[0033] In this embodiment, a method for playing media data is provided. Figure 2 It is a flowchart of the method for playing media data according to an embodiment of the present invention, as Figure 2 shown, and the process includes the following steps:

[0034] S202, in response to a target play operation, play the target historical media data at a preset speed, where the target historical media data is the media data that needs to be played selected by the target play operation;

[0035] Optionally, in this embodiment, the above-mentioned media data may be images that can be played by a user collected by video capture devices such as cameras, cameras, and webcams. Among them, the steps of collecting and saving video data may include, but are not limited to, being synchronized.

[0036] Optionally, in this embodiment, the above-mentioned target play operation may include, but is not limited to, operations such as clicking, dragging, double-clicking, and inputting voice commands that can be used to indicate playing media data.

[0037] For example, Figure 3 is a schematic diagram of a specific example of a method for playing media data according to an embodiment of the present invention. As Figure 3 shown, the user performs a target play operation 302 on the client interface 301 to select the target historical media data 304 in the media data list 303.

[0038] The above is only an example, and the present application does not make any specific limitations.

[0039] Optionally, in this embodiment, the above-mentioned preset speed may include, but is not limited to, a speed set in advance according to requirements. The preset speed may be 1x speed, or may also be 0.75x speed, 1.75x speed, etc. No specific limitation is made on what the preset speed is set to.

[0040] Optionally, in this embodiment, the above-mentioned target historical media data may include, but is not limited to, the media data that has been saved after the user's retrieval. Among them, the target historical media data is the media data that needs to be played selected by the target play operation.

[0041] S204. After the playback of the target historical media data ends, play the first historical media data at N times the speed, where the playback duration of the target historical media data is the target playback duration. The first historical media data is the media data saved after being recorded for the target playback duration during the playback of the target historical media data. The system time when the recording of the first historical media data starts is the first start time, and the system time when the recording of the first historical media data ends is the first end time. N times the speed represents N times the preset speed, and N is greater than 1.

[0042] Optionally, in this embodiment, the above-mentioned first historical media data may include, but is not limited to, images that can be played by users collected by video recording devices such as cameras, cameras, and webcams. The first historical media data may also include, but is not limited to, data in formats such as videos, audios, animations, and texts. The first historical media data may be the media data saved after being recorded for the target playback duration during the playback of the target historical media data.

[0043] Optionally, in this embodiment, the above-mentioned first start time may include, but is not limited to, the system time when the recording of the first historical media data starts; the above-mentioned first end time may include, but is not limited to, the system time when the recording of the first historical media data ends. The duration between the first start time and the first end time is determined by the target playback duration and N times the speed, and N times the speed represents N times the preset speed.

[0044] Optionally, in this embodiment, the above-mentioned target playback duration may include, but is not limited to, 1 second, 8 seconds, 1 minute, 1 hour, etc. The target playback duration is the total time used for the target historical media data from the start of playback to the end of playback. The specific size of the target playback duration is determined by the total duration of the target historical media data and the preset playback speed.

[0045] For example, when the preset speed is 1 and N is 2, N times the speed is 2 times the speed. When the duration of the target historical media data is 8 seconds and the 2 - times - speed target historical media data is played starting from 1:00 am, the target historical media data can be played in 4 seconds. At this time, the target playback duration is 4 seconds. Then the start time of recording the first historical media data is 1:00 am, and the end time of recording is 1:04 am.

[0046] Optionally, in this embodiment, the above-mentioned event video data may include, but is not limited to, video data that has been collected and saved by video recording devices such as cameras, cameras, and webcams. When the user plays the video data, they can choose to play it at normal speed or at multiple speeds according to their personal needs.

[0047] S206, when the first time difference between the first end moment and the first current moment is less than or equal to the first preset threshold, play the target real-time media data at a preset speed, where the target real-time media data is the media data collected by the real-time image acquisition device at the first current moment, and the first current moment represents the current system moment when the playback of the first historical media data ends.

[0048] Optionally, in this embodiment, the above-mentioned first current moment is used to represent the specific time corresponding to the end of the playback of the first historical media data. The specific time may include, but is not limited to, any specific time point from 0:00 to 24:00. It may be determined by the time where the user is located, or may be determined by taking the start recording time as 0:00 and incrementing the recording time from 0:00 to the time when the playback of the first historical media data ends. The above-mentioned first current moment represents the current system moment when the playback of the first historical media data ends. Among them, the above-mentioned first time difference may include, but is not limited to, the difference between the first end moment and the first current moment.

[0049] Optionally, in this embodiment, the above-mentioned target real-time media data may include, but is not limited to, the media data collected by the real-time image acquisition device at the first current moment. The media data may include, but is not limited to, data in formats such as video, audio, animated text, etc. For example, the target real-time media data may be the news broadcast picture at 7 pm every night, the latest live game picture, real-time voice call data, real-time video data, and other media data.

[0050] Optionally, in this embodiment, the above-mentioned first preset threshold may include, but is not limited to, being pre-set by relevant technical personnel according to prior data. The first preset threshold may be set to 1 minute, or may also be set to 3 seconds. The specific setting time is determined according to actual needs. When the above-mentioned first time difference is less than or equal to the first preset threshold, after playing the first historical media data, the target real-time data may be played at a preset speed.

[0051] Through the embodiments of the present application, in response to a target playback operation, play the target historical media data at a preset speed. After the playback of the target historical media data ends, play the first historical media data at N times the speed. When the first time difference between the first end moment and the current system moment is less than or equal to the first preset threshold, after the playback of the first historical media data ends, play the target real-time media data at a preset speed, enabling the user to seamlessly switch from historical media data to target real-time media data naturally. It solves the problem in the related art that the playback scheme of media data is relatively complex, resulting in low display efficiency, and achieves the technical effects of improving the playback efficiency of media data and simplifying the playback method of media data.

[0052] As an alternative embodiment, after the playback of the target historical media data ends and the first historical media data is played back at N times the speed, the method further includes: when the first time difference is greater than the first preset threshold, after the playback of the first historical media data ends, the second historical media data is played back at N times the speed, where the second historical media data is the media data saved after being recorded for the first playback duration during the playback of the first historical media data, the first playback duration is the ratio of the target playback duration to N, the system time when the recording of the second historical media data starts is the second start time, and the system time when the recording of the second historical media data ends is the second end time; when the second time difference between the second end time and the second current time is less than or equal to the first preset threshold, the target real-time media data is played back at a preset speed, where the second current time represents the current system time when the playback of the second historical media data ends.

[0053] Optionally, in this embodiment, the above-mentioned second historical media data may include, but is not limited to, data in formats such as video, audio, animated text, etc. The second historical media data is the media data saved after being recorded for the first playback duration during the playback of the first historical media data, that is, the second historical media data is recorded for as long as the first historical media data is played. The second historical media data is the media data recorded after the first historical media data.

[0054] It should be noted that the above-mentioned first playback duration being the ratio of the target playback duration to N can be understood as, for example, if the target playback duration is 8 seconds and the playback speed is 2 times, the first playback duration is 4 seconds.

[0055] Optionally, in this embodiment, the above-mentioned first playback duration represents the duration between the first start time and the first end time, and the second media data will be continuously recorded within this duration. The above-mentioned second start time may include, but is not limited to, the system time when the recording of the second historical media data starts, and the second end time may include, but is not limited to, the system time when the recording of the second historical media data ends.

[0056] Optionally, in this embodiment, the above-mentioned second current time may include, but is not limited to, any time between 0:00 and 24:00 in a day. This time represents the current system time corresponding to when the playback of the second historical media data ends. For example, if the time when the playback of the second historical media data ends is 6:00, then the second current time is 6:00.

[0057] Optionally, in this embodiment, the second time difference may include, but is not limited to, the difference between the second end time and the second current time. When the second time difference is less than or equal to the first preset threshold and the playback of the second historical media data ends, the target real-time media data is played at a preset speed.

[0058] Through the embodiments of the present application, when the first time difference is greater than the first preset threshold, the second historical media data is played at N times the speed. When the second time difference between the second end time and the second current time is less than or equal to the first preset threshold and the playback of the second historical media data ends, the target real-time media data is played at a preset speed. In this way, the playback is switched from the second historical real-time media data to the target real-time media data. By storing the second historical media data, playing it at a preset multiple speed and catching up with the target real-time data, and then seamlessly switching to play the target real-time media data, the problems in the related art that the playback scheme of media data is relatively complex are solved, and the efficiency of switching from playing historical media data to playing target real-time media data is improved, and the technical effect of simplifying the media data switching playback method is achieved.

[0059] As an optional embodiment, the method further includes: when the first time difference is greater than the first preset threshold, after the playback of the first historical media data ends, playing the second historical media data at N times the speed, including: when the first time difference is greater than the first preset threshold, determining the second start time according to the first end time, where the system times indicated by the first end time and the second start time are the same; searching for the second historical media data according to the second start time and playing the second historical media data at N times the speed.

[0060] Optionally, in this embodiment, the first end time may include, but is not limited to, the system time when the recording of the first historical media data ends. Whenever the recording of the first historical media data ends, the first end time is the time when the recording ends. At the same time when the recording of the first historical media ends, the recording of the second historical media data starts, that is, the system times indicated by the first end time and the second start time are the same.

[0061] For example, when the first preset threshold is 3 seconds and the first time difference is 5 seconds, the recording of the second media data continues. If the first time difference is 3 seconds or less than 3 seconds, the recording of the second historical media data will not be performed.

[0062] Through the embodiments of the present application, when the first time difference is greater than the first preset threshold, the second start time is determined according to the first end time, the second historical media data is searched according to the second start time, and the second historical media data is played at N times the speed, achieving the effect of playing while storing, effectively avoiding the problem that after the latest queried video is played, it is necessary to query and update the file again.

[0063] As an alternative embodiment, the above method further includes: searching for the second historical media data according to the second start time and playing the second historical media data at N times the speed, including: obtaining target index information, where the target index information records the second start time, the second end time, and when the second historical media data has not been recorded yet, the second end time is the system time when the first historical media data is played, and when the second historical media data has been recorded, the second end time is the system time when the second historical media data is recorded; searching for the second historical media data according to the second start time and the second end time, and playing the second historical media data at N times the speed.

[0064] Optionally, in this embodiment, the above target index information may include, but is not limited to, relevant information such as the start recording time, end recording time, and estimated time to end recording of the media data. Among them, the above target index information may be index information recording the second start time and the second end time.

[0065] Optionally, in this embodiment, the above target index information may include, but is not limited to, the media data file corresponding to the recorded end, the media data file that is being recorded and has not been recorded yet. When the media data corresponding to the target index information has ended recording, the target index information may include, but is not limited to, the start recording time and the end recording time; when the media data corresponding to the target index information is being recorded and has not been recorded yet, the target index information may include, but is not limited to, the start recording time of the media data, the estimated end recording time, the estimated remaining recording time, the estimated size of the remaining recorded media data, etc. At this time, the media data that is being recorded and has not been recorded yet can be played through this target index information, and the target index information is continuously updated as the media data is recorded.

[0066] It should be noted that when the second historical media data has not been recorded yet, the second end time is the system time when the first historical media data is played, and when the second historical media data has been recorded, the second end time is the system time when the second historical media data is recorded.

[0067] Through the embodiments of the present application, by obtaining target index information, when the second historical media data has not been recorded yet, the second end time is the system time when the first historical media data is played to completion; when the second historical media data has been recorded, the second end time is the system time when the second historical media data is recorded to completion. By searching for the second historical media data according to the second start time and the second end time, and playing the second historical media data at N times the speed, the problem that after the latest retrieved video is played, there will be an updated file that needs to be queried again can be effectively avoided.

[0068] As an optional embodiment, the above method further includes: when the first time difference is greater than the first preset threshold and less than or equal to the second preset threshold, before playing the first historical media data, establishing a transmission channel for real-time media data, and during the playing of the first historical media data, caching the first real-time media data, where the second preset threshold is greater than the first preset threshold, and the first real-time media data is media data collected by a real-time image acquisition device between the first start time and the first end time; after the first historical media data is played, playing the first real-time media data at M times the speed, where the system time when the first real-time media data starts to be cached is the third start time, the system time when the first real-time media data ends caching is the third end time, and M times the speed represents M times the preset speed, and M is greater than 1; when the third time difference between the third end time and the third current time is less than or equal to the first preset threshold, playing the target real-time media data at the preset speed, where the third current time represents the current system time when the first real-time media data is played to completion.

[0069] Optionally, in this embodiment, the above second preset threshold may include but is not limited to being set by relevant technical personnel according to historical data or prior experience.

[0070] For example, if the first time difference is 5 seconds, the first preset threshold is 3 seconds, and the second preset threshold is 5 seconds, at this time 3 seconds < 5 seconds = 5 seconds, that is, the first preset threshold < the first time difference = the second preset threshold, meeting the above conditions, and at this time, a transmission channel for real-time media data is established before playing the first historical media data. When the first time difference is within the second threshold, preparations are made to switch from historical media data to real-time media data.

[0071] Optionally, in this embodiment, the above transmission channel for real-time media data may include but is not limited to a channel that can transmit and cache real-time media data for a certain period of time.

[0085] It should be noted that the second real-time media data is cached during the playback of the third historical media data and is played at M times the speed after the playback of the third historical media data ends.

[0086] Through the embodiments of the present application, when the first time difference is greater than the second preset threshold, after the playback of the first historical media data ends, the third historical media data is played at N times the speed. Then, when the fourth time difference between the fourth end time and the fourth current time is greater than the first preset threshold and less than or equal to the second preset threshold, a transmission channel for real-time media data is established before the playback of the third historical media data, and during the playback of the third historical media data, the second real-time media data is cached.

When the fifth time difference between the fifth end time and the fifth current time is less than or equal to the first preset threshold, the target real-time media data is played at a preset speed. In this way, the problem in the related art that the switching playback scheme of media data is relatively complex, resulting in low efficiency of switching playback of media data, is solved, and the technical effect of improving the efficiency of switching playback of media data and simplifying the switching playback method of media data is achieved.

[0087] As an alternative embodiment, after the playback of the target historical media data ends, update the page playback progress bar. Wherein, the end moment before the update of the page playback progress bar is the system moment when the target historical media data ends recording, and the end moment after the update of the page playback progress bar is the first end moment; when starting to play the target real-time media data at a preset speed, cancel the display of the page playback progress bar and display a target prompt message, where the target prompt message indicates that the currently playing media data is real-time media data.

[0088] Optionally, in this embodiment, the above-mentioned page playback progress bar may include, but is not limited to, a graph represented by a timeline to represent the playback progress of the media data.

[0089] Optionally, in this embodiment, the above-mentioned target prompt message may include, but is not limited to, information such as graphics, animations, texts, data, sounds, etc. that can be used to remind the user. The above-mentioned target prompt message can be to remind the user that the currently played data is real-time media data.

[0090] For example, the user receives a message: "The historical media data has been played, and now the real-time media data is being played." At this time, the played data will be the latest real-time media data, and the double-speed playback will no longer be available. At this time, the latest media data cannot be obtained by adjusting the position of the progress bar either. One can only wait for the update. The user can only play along with the latest real-time media data or adjust the progress bar back to the position of the previous historical media data for playback.

[0091] It should be noted that after the end of the playback process of the target historical media data, since the real-time media data is continuously updated during the playback process of the target historical media data, the page progress bar will also be updated accordingly. And the end moment before the update of the page playback progress bar is the system moment when the target historical media data ends recording. When playing the target real-time media data at a preset speed, cancel the display of the page playback progress bar and display a target prompt message, where the target prompt message indicates that the currently playing media data is real-time media data.

[0092] Optionally, in this embodiment, the above-mentioned first end moment may include, but is not limited to, the end moment after the update of the page playback progress bar.

[0093] The present invention will be specifically described below with reference to specific embodiments:

[0094] The current video recording files are saved according to a certain strategy. For example, after the video data is written into a certain video recording file for 5 minutes, the video recording file file1 ends, and then a new video recording file file2 is created for saving. After file1 ends, the index information of this video recording saves the start and end times of this video data. However, the index information of file2 only saves the start time. When querying the video recording currently, if a certain time is used as the start time and the current system time is used as the end time, then only the video data of this part is returned. When playing, it can only play up to the video with the system time as the end time at the time of querying.

[0095] For example, when a user queries the device video recording on the client, and queries according to the start time and end time. If the end time is the current system time T_curr and the start time is T_s, the device returns 3 video recordings, including the latest video recording file that is being written, as Figure 4 shown. If the user selects to play the video at normal speed starting from file2 until the time of playing to file3 is a total of 4t, then after playing the above 4t video recording, the device saves the latest video recording with a duration of 4t again and creates a new file file4, as Figure 5 shown. Since the user only queries the video recording with a duration of t at the beginning of file3, if the user wants to continue playing the updated video after playing the video recording with a duration of t at the beginning of file3, a new query needs to be made.

[0096] If the user selects to play Figure 4 the file3 in it at normal speed for a duration of t, then the playing is completed. At this time, file3 has appended a video recording with a duration of t. When currently playing this appended video recording, to exit the playing page to the query interface and then query and play again. After the playing is completed, the above problem will still be encountered, that is, after the latest video recording is played, an updated file will be generated and a new query is required, which is extremely inconvenient for the user to operate.

[0097] To solve the above problems, the following solutions are proposed:

[0098] In the above example, after the user queries 3 files (file1, file2, file3), plays file3 at normal speed, and the video recording index information of file3 is returned by the device. If the file has ended writing, the index information returns the complete start and end times; if the file is being written, the extended index information is returned. The extended index information includes the following content:

[0099] (1) The start time T_b when the file starts recording the video;

[0100] (2) The current system time as the end time T_curr for the video recording query;

[0101] (3) Estimate how long it will take to finish writing file3, i.e., the remaining writing time 2t;

[0102] (4) The remaining writable file size size;

[0103] (5) The estimated end writing time Te of this file.

[0104] When the client finishes playing the t-duration video of file3 and reaches time T_curr, the client background queries the device again for the video after T_curr, i.e., the start time is T_curr and the end time is the system time denoted as T_c1. Since the client has received the index information of file3, after the playback duration t, it predicts whether the current file will be finished. If this file will be finished, it queries the updated file; if not, it queries the current file.

[0105] For example, in this example, after file3 has been played for the duration t, file3 has written another t-duration video, i.e., a video with a total duration of 2t. When playing to the end time T_curr, the client queries the device for the video. Since file3 is not finished, the extended index information returned includes the following:

[0106] (1) The start time T_curr when the file starts recording the video;

[0107] (2) The current system time as the end time T_c1 for video query;

[0108] (3) Estimate how long it will take to finish writing file3, i.e., the remaining writing time t;

[0109] (4) The remaining writable file size size1;

[0110] (5) The estimated end writing time Te of this file.

[0111] (4) The remaining writable file size size; After the video is returned to the client, the client playback page updates the page playback progress bar in a timely manner, and the end time of the progress bar is T_c1. After the previous video is played, it starts playing from the immediately following playback progress bar, and the end time of the playback is T_c1, as Figure 6 shown.

[0112] When playing the newly queried video, regardless of the previous playback mode, intelligent playback is used when playing the new video. That is, event data is played at normal speed, and normal videos are played at 2x / 4x speed. If the proportion of event videos is more than 50%, normal videos are played at 4x speed; if the proportion of event videos is less than 50%, normal videos are played at 2x speed. For the sake of description, all videos in file3 in this example are normal videos. When playing a video with a duration of t between T_curr and T_c1 at 2x speed, it takes t / 2 time, and the actual device stores another t / 2 duration of video. When it reaches the time of T_c1, the client queries the video again. The start time is T_c1, the end time is the system time T_c2, and the duration is approximately t / 4. When playing a video with a duration of t / 4 at 2x speed, it takes approximately t / 8 time, and the actual device stores another t / 8 duration of video. As Figure 7 shown. That is, subsequent queries and playbacks are the same as before. When the current video is finished playing, the background uses the end time of the current video as the start time and the system time as the end time to query for new videos. The new videos may be only in the current file, or it is possible that the current file has been written full and ended, and a new file has been created to write the video. After the video is found, intelligent playback starts until the playback time of the video catches up with the live video screen.

[0113] Before the video playback time catches up with the live video screen, if the client requests to establish a live media stream from the device 3 seconds before the preset time, at this time, the live media stream and the video media stream are sent to the client at the same time. In order to achieve seamless switching from video data to the live media stream, seamless switching can be achieved by caching data on the client. When the client is playing the video that is the latest from the live stream on the device at variable speed and needs to switch to the live stream, the client notifies the device end that a bitrate switch is required. Then, when the device end returns the latest video to the client, it sends the live stream to the client at the same time. As Figure 8 , the client plays the video file sent by the device end and caches the live stream. After the client finishes playing the latest video at variable speed, it plays a relatively older live stream in the cache at variable speed until it is all live media stream and then plays it at normal speed. Thus, bitrate switching can be performed. At this time, there is no progress bar for video playback, and the playback page prompts that it has been switched to live data.

[0114] The above is all for ordinary video recording. When there is actual event video recording, in the case of a large number of event videos, the ordinary video is played at 4 times the speed, and the video playback can still catch up with the live stream. The principle of the video data stored in blocks is the same. That is, when there is a new block to be stored and the storage space is sufficient, the current video segment index only has a start time, and the video data is continuously written without an end time. Then, according to the above method, for the video near the live stream, the ordinary video can also be played at a multiple speed to catch up with the live stream. After catching up with the live stream, switch to the live stream and continue playing. After the client queries the latest video of the device and sends a live stream establishment message, and notifies the device that it is seamlessly switching the media stream, after the device sends the video query result, it sends the real-time stream after this video to the client for caching. The client first plays the latest video data at a multiple speed. After playing, it plays a segment of the cached live stream at a multiple speed until it can play the real-time stream. Since the event video is played at normal speed, when the event video cannot catch up with the live time and there is too much live data cached by the client, when the client finishes playing the current video, it re-queries the video and caches the new live stream. For block-stored videos, it is also possible to avoid the situation that after the latest video is played, a new video file needs to be queried and played again, which is extremely inconvenient for user operations. The same applies to other storage methods.
