[0002] With the continuous development of terminal devices, playing video, audio and other media data through terminals is widely used by users. In the process of playing the above media data, it is necessary to obtain the corresponding data from the server and play it.

[0003] Due to the network status of the terminal device, there may be problems such as freezing during the playback of media data. In order to ensure the smoothness of media data playback, cache data of media data is set on the terminal. Therefore, the size of cache data is an important factor to pay attention to during the playback of media data. Summary of the invention

Thus, the user can autonomously choose whether to provide personal information to software or hardware such as an electronic device, application, server, or storage medium that performs the operation of the technical solution of the present disclosure according to the prompt message.

In addition, the pop-up window may also carry a selection control for the user to choose "agree" or "disagree" to provide personal information to the electronic device.

[0034] It is understandable that the above notification and the process of obtaining user authorization are merely illustrative and do not constitute a limitation on the implementation of the present disclosure. Other methods that meet the relevant laws and regulations may also be applied to the implementation of the present disclosure.

[0035] It is understandable that the data involved in this technical solution (including but not limited to the data itself, the acquisition or use of the data) shall comply with the requirements of relevant laws, regulations and relevant provisions.

[0036] For example, see Figure 1 , Figure 1 : is a schematic diagram of an application scenario provided by an embodiment of the present disclosure. Among them, the uploading terminal is connected to the server in communication, and the server is connected to the viewing terminal in communication. The uploading terminal is used to upload media data to the server, and the server stores the media data uploaded by the uploading terminal. The viewing terminal requests the media data from the server, caches it locally and plays it. It can be understood that the uploading terminal and the viewing terminal can be the same electronic device or different electronic devices. Here, the uploading terminal and the viewing terminal can include but are not limited to electronic devices such as mobile phones, tablet computers, PCs or computers.

[0037] In this embodiment, the media data includes but is not limited to audio data, video data, etc. Among them, the video data includes long videos or short videos, etc.

[0038] During the playback of any of the above types of media data, the media data is requested from the server and cached locally. The cached data is judged by the cache threshold, and the media data is played when the amount of cached data meets the cache threshold. At present, the cache threshold is generally a pre-set fixed value. Therefore, the cache threshold cannot be dynamically adjusted and cannot be applied to different terminals, especially terminals with poor network status. Compared with terminals with good network status, the above cached data is judged based on the same cache threshold. Terminals with poor network status are more likely to experience playback jams, which affects the smoothness of the media data playback process.

[0039] In view of the above technical problems, an embodiment of the present invention provides a playback control method, see Figure 2 , Figure 2 The present invention provides a flowchart of a playback control method provided by an embodiment of the present invention. The present invention is applicable to the case where the cached data is judged when the media data is in a non-playing state to switch to a playing state. The method can be executed by a playback control device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, which can be a mobile terminal, PC, etc. Figure 2 As shown, the method includes:

[0040] S110: When the media data is in a non-playing state, obtain current cache data of the media data, and obtain freeze data of the playback device within a preset time window.

[0041] S120: Determine a playback cache threshold based on the jamming data.

[0042] S130: Perform a playback determination on the current cached data based on the playback cache threshold; if the current cached data satisfies a playback condition corresponding to the playback cache threshold, switch the non-playback state to a playback state, and play the media data based on the current cached data.

[0043] In this embodiment, the non-playing state of the media data includes a stuck state and an unstarted state, wherein the unstarted state is a state where the media data is not started to play. The stuck state is a paused state caused by a stuck play during the playing of the media data.

[0044] When the terminal is in a non-playing state or a stuck state, media data is requested from the server and cached locally, that is, the cached data of the media data continues to increase. Switching from the non-playing state to the playing state, and switching from the stuck state to the continued playing state, both require that the amount of cached data is greater than or equal to the playback cache threshold. Here, the playback cache threshold is a dynamic threshold, that is, when the media data switches to the non-playing state, the playback cache threshold applicable to the current non-playing state is determined, and the amount of cached data in the current non-playing state is determined.

[0045] In this embodiment, when it is detected that the media data is in a non-playing state, the jamming data of the playback device within a preset time window is obtained to determine the current playback cache threshold. The preset time window may be a historical time period before the current moment, and the current moment is the end time of the preset time window. Exemplarily, the duration of the preset time window may be 100ms, 1 minute, 5 minutes, etc., which may be determined according to the detection requirements.

[0046] The jamming data characterizes the jamming degree within a preset time window. For example, the larger the jamming data, the more serious the jamming state. Furthermore, the jamming data can characterize the network state of the playback device (such as a viewing terminal). For example, the smaller the jamming data, the better the network state of the playback device within the preset time window, and the larger the jamming data, the worse the network state of the playback device within the preset time window. By determining the jamming data and determining the playback cache threshold based on the jamming data, the determined playback cache threshold is applicable to the network state of the playback device.

[0047] Optionally, obtaining the jamming data of the playback device within a preset time window may be to obtain the number of jamming times within the preset time window as the jamming data. A jamming data set may be created in advance, and the jamming data set is used to store jamming information, wherein the jamming information may include a jamming identifier and a jamming timestamp. In the event that any media data is detected to be jammed during playback, jamming information is generated and stored in the above-mentioned jamming data set. In some embodiments, multiple jamming data sets may be created and maintained according to the type of media data, for example, including a video jamming data set, an audio jamming data set, etc. Accordingly, when the media data is in a non-playing state, a jamming data set of a corresponding type is called according to the type of the media data to determine the jamming data of the corresponding type of media data.

[0048] According to the preset time window, a match is performed in the above-mentioned jamming data set to determine the jamming information / jamming identification where the jamming timestamp is within the above-mentioned preset time window, and the number of the above-mentioned jamming information / jamming identification, that is, the number of jamming times, is counted as the jamming data.

[0049] In some embodiments, the jamming data set may be a jamming data set corresponding to a preset time window, that is, when a new jamming occurs, the generated jamming information is added to the jamming data set, and when the timestamp corresponding to the stored jamming information exceeds the time range of the preset time window, the jamming information is removed from the jamming data set. Accordingly, the number of jamming information / jamming identifiers in the jamming data set is counted to obtain the number of jamming times as the jamming data within the preset time window.

[0050] Optionally, obtaining the jamming data of the playback device within a preset time window may be to obtain the jamming duration within the preset time window as the jamming data. The jamming timestamp in the jamming information in the jamming data set may include a jamming start timestamp and a jamming end timestamp, and the jamming duration of each jamming may be determined based on the jamming timestamp. The jamming duration within the preset time window is determined by summing the jamming durations corresponding to the jamming information within the preset time window, and the jamming duration within the preset time window is determined as the jamming data.

[0051] Optionally, obtaining the jamming data of the playback device within a preset time window may be by obtaining the number of jamming times within the preset time window, obtaining the jamming duration within the preset time window, and determining the jamming data based on the number of jamming times and the jamming duration. Exemplarily, the jamming data may be determined as the product of the number of jamming times and the jamming duration. Exemplarily, the jamming data may be determined based on (1+number of jamming times)*(1+jamming duration). The jamming data is determined by the number of jamming times and the jamming duration, thereby improving the accuracy of the jamming data.

[0052] Since the playback duration in the preset time window is uncertain, the number of freezes in the two preset time windows is n, and the playback duration in the first preset time window is longer than that in the second preset time window. Accordingly, it can be known that the network status of the playback device in the first preset time window is better than that in the second preset time window. In order to avoid the interference of the above-mentioned playback duration on the freeze data and network status, the freeze data of the playback device in the preset time window can be obtained by obtaining the number of freezes in the preset time window and the playback duration of the preset time window, and taking the ratio data of the number of freezes to the playback duration as the freeze data. Among them, the playback duration of the preset time window can be determined according to the playback time information of the historical media data, and the total playback duration in the preset time window is determined. By taking the ratio data of the number of freezes to the playback duration as the freeze data, the accuracy of the freeze data is improved.

[0053] In some embodiments, the playback duration of the playback device in the preset time window may be the playback duration of media data of the same type as the media data currently being played within the preset time window.

[0054] Optionally, obtaining the jamming data of the playback device within a preset time window may be to obtain the jamming duration within the preset time window and the playback duration of the preset time window, and use the ratio data of the jamming duration to the playback duration as the jamming data. Here, the method for determining the jamming duration within the preset time window and the playback duration of the preset time window is not repeated.

[0055] On the basis of the above embodiments, the playback cache threshold is determined based on the stuttering data determined by any of the above methods. It should be noted that the non-playback state includes a stuttering state and a not-started state, wherein the playback cache thresholds determined by the stuttering state and the not-started state are different. Here, the status identifier of the playback device may be read to determine whether the playback device is in a stuttering state or a not-started state. Exemplarily, the status identifier may be 1 or 0, wherein 1 may represent a stuttering state and 0 may represent a not-started state. The specific form of the status identifier is not limited here, and it can be used to distinguish between a stuttering state and a not-started state.

[0056] In some embodiments, the determination strategies of the playback cache thresholds corresponding to the stuck state and the non-starting state are pre-set, and the corresponding determination strategies of the playback cache thresholds are called according to the determined stuck state or non-starting state, and the current playback cache threshold is obtained based on the stuck data and the above-mentioned determination strategies of the playback cache thresholds. Among them, the determination strategy of the playback cache threshold may include calculation rules and calculation factors, and accordingly, in the determination strategies of the playback cache thresholds corresponding to the stuck state and the non-starting state, one or more of the calculation rules and calculation factors are different. Among them, the calculation factor is a parameter in the calculation rule, which can be one or more, determined according to the calculation requirements. The calculation rule is a processing rule for the calculation factor and the stuck data to obtain the playback cache threshold. Accordingly, the determination strategy of the playback cache threshold is called according to the state type, and the determination strategy of the playback cache threshold may include a preset calculation formula, and the calculation formula includes the to-be-determined stuck data and the preset calculation factor, and the stuck data is input into the above-mentioned determination strategy of the playback cache threshold to obtain the playback cache threshold corresponding to the state type.

[0057] In some embodiments, determining the playback cache threshold based on the jam data includes: obtaining the state type of the non-playing state of the media data, determining the corresponding calculation factor based on the state type; and determining the playback cache threshold corresponding to the state type based on the calculation factor and the jam data. Here, the state types of the non-playing state include the jam state and the non-playing state. Accordingly, the jam state and the non-playing state have different calculation factors corresponding to them, and the calculation factor corresponding to the current state data is read. Based on the read calculation factor and the determined jam data, the playback cache threshold corresponding to the state type is determined.

[0058] Optionally, the calculation factor includes initial data and growth parameters, wherein the initial data may be a minimum playback cache threshold. The playback cache threshold increases with the increase of the jam data, and the growth data may be unit growth data of the playback cache threshold. Accordingly, determining the playback cache threshold corresponding to the state type based on the calculation factor and the jam data includes: determining the growth data based on the growth parameter and the jam data, and determining the playback cache threshold based on the growth data and the initial data.

[0059] Exemplarily, the product of the jam data and the growth data may be determined as the growth data; Exemplarily, the jam data may be processed by a preset type to obtain a jam parameter, and the product of the jam parameter and the growth data may be determined as the growth data. The preset types of jam data processing herein include, but are not limited to, exponential data, preset type processing, etc., which are not limited here.

[0060] In some embodiments, determining the growth data based on the growth parameter and the jamming data includes: performing preset type processing on the jamming data to obtain the jamming parameter; determining the growth data based on the jamming parameter and the growth parameter. Among them, the preset type processing includes logarithmic function processing, exponential function processing, power function processing, etc. In some embodiments, the preset type processing is logarithmic function processing. By performing logarithmic function processing on the jamming data, when the jamming data increases, it can be clearly reflected in the growth data and the playback cache threshold, and the playback cache threshold applicable to the jamming data is obtained, and the cache data in the current non-playing state is determined.

[0061] Exemplarily, the growth data may be determined by: growth parameter * log (1 + stuck data). Furthermore, the sum of the above growth data and the initial data is determined as the playback cache threshold, or the playback cache threshold is calculated based on the following formula: initial data * (1 + growth data). In summary, for the stuck state, the first growth parameter and the first initial data corresponding to the stuck state are read, the first growth data is determined based on the first growth parameter and the stuck data, and the playback cache threshold corresponding to the stuck state is determined based on the first growth data and the first initial data. For the not-started state, the second growth parameter and the second initial data corresponding to the not-started state are read, the second growth data is determined based on the second growth parameter and the stuck data, and the playback cache threshold corresponding to the not-started state is determined based on the second growth data and the second initial data.

[0062] On the basis of the above-mentioned embodiment, before playing the media data, the media data is preloaded and cached, and when switching to playing the media data, the media data is played based on the preloaded data. It should be noted that when switching to playing the media data, the preloading process of the media data is stopped, and the amount of preloaded data no longer increases, but the cached data of the media data can continue to be obtained to increase the amount of cached data. In this embodiment, the network status of the playback device can be characterized according to the amount of preloaded data, wherein the larger the amount of preloaded data, the better the network status of the playback device, and conversely, the smaller the amount of preloaded data, the worse the network status of the playback device. In the non-playing state, different playback cache thresholds are determined according to the amount of preloaded data to adapt to different network states and improve the accuracy of the playback cache threshold.

[0063] For the non-started state, the preloaded data for the media data is determined, and the start type of the media data is determined based on the preloaded data, and the start type includes preloaded start and non-preloaded start. Wherein, when the amount of preloaded data is greater than or equal to the preset preload threshold, the start type is determined to be preloaded start, and when the amount of preloaded data is less than the preset preload threshold, the start type is determined to be non-preloaded start. Wherein, preloaded start and non-preloaded start can respectively correspond to different playback cache threshold determination strategies, that is, preloaded start and non-preloaded start can correspond to different calculation factors and / or calculation rules.

[0064] In some embodiments, the method for determining the playback cache threshold includes: calling the corresponding calculation factor according to the determined start type; and determining the playback cache threshold corresponding to the start type based on the determined calculation factor and the freeze data. Correspondingly, the playback cache threshold corresponding to the non-start state includes a preloaded playback cache threshold and a non-preloaded playback cache threshold.

[0065] Optionally, the calculation factor corresponding to the preloaded start is smaller than the calculation factor corresponding to the non-preloaded start. Furthermore, when the jamming data is the same, the preloaded start cache threshold is smaller than the non-preloaded start cache threshold to ensure that the number of jamming events is reduced after switching to the playback state.

[0066] On the basis of the above embodiment, after determining the playback cache threshold corresponding to the state type based on the calculation factor and the jamming data, it also includes: obtaining the preset maximum threshold corresponding to the state type; if the playback cache threshold corresponding to the state type exceeds the preset maximum threshold corresponding to the state type, updating the playback cache threshold based on the preset maximum threshold.

[0067] In order to avoid the situation where the playback cache threshold is too large, resulting in a long non-playing state, a preset maximum threshold corresponding to each state type is set, and the determined playback cache threshold is determined to avoid the problem of being in the non-playing state for too long.

[0068] After determining the playback cache threshold corresponding to the current non-playing state, the data volume of the current cached data is determined based on the playback cache threshold, and it is determined that the data volume of the current cached data is greater than or equal to the playback cache threshold. If so, it indicates that the current cached data meets the playback condition, and the media data is played based on the current cached data. If not, it indicates that the current cached data does not meet the playback condition, then continue to obtain the cached data, and re-read the current cached data after a preset time interval to re-determine the playback condition until the playback condition is met or the duration of the non-playing state meets the timeout duration, switch to the playback state, and play the media data based on the current cached data.

[0069] In some embodiments, when the current cached data does not meet the playback conditions, the jamming data can be reacquired and the playback cache threshold can be re-determined. Accordingly, after a preset time interval, the current cached data to be read is determined based on the re-determined playback cache threshold.

[0070] The technical solution of the disclosed embodiment is that when a playback device plays media data and the media data is in a non-playing state, the jamming data of the playback device in a preset time window is read to determine a playback cache threshold suitable for the current playback device based on the jamming data. The recent cause effect of jamming is fully considered, and the jamming data in the preset time window is updated in real time. In the case of a non-playing state, the latest jamming data is read to ensure the accuracy of the jamming data. The playback cache threshold is determined by the jamming data, that is, the obtained playback cache threshold meets the requirements of the jamming data, that is, meets the requirements of the network status of the playback device. The current cache data is judged by the playback cache threshold to determine whether the playback conditions are met, and the playback state is switched to play the media data when the playback conditions are met. Among them, the current cache threshold meets the playback conditions, indicating that the cache data continuously obtained under this network state can ensure the smoothness of playback and reduce playback jams.

[0071] Based on the above embodiment, a preferred example of a playback control method is provided. Figure 3 , Figure 3It is a flow chart of a playback control method provided by an embodiment of the present invention. When the media data is in a non-playing state, it is determined that the state type of the non-playing state is a stuck state or a non-playing state. For the stuck state, the stuck data and the current cached data in the preset time window are read, and the corresponding playback cache threshold is determined based on the stuck data, that is, the stuck water level rebuf_dur. Specifically, it can be calculated based on the following formula: rebuf_dur = min(rebuf_dur_min*(1+rebuf_dur_inc_factor*log(1+rebuf_count)), rebuf_dur_max), where rebuf_dur_min is the initial data corresponding to the stuck state, rebuf_dur_inc_factor is the growth data corresponding to the stuck state, rebuf_count is the number of stuck times, that is, the stuck data, and rebuf_dur_max is the preset maximum threshold corresponding to the stuck state. It should be noted that rebuf_count here is only an example of jamming data. In other embodiments, the jamming data may also be the jamming duration rebuf_time, or the jamming data determined by the number of jamming times and the jamming duration, or the jamming data determined by the number of jamming times and the playing duration, or the jamming data determined by the jamming duration and the playing duration, etc. For example, rebuf_dur = min(rebuf_dur_min*(1+rebuf_dur_inc_factor*log(1+(1+rebuf_count)*(1+rebuf_time))), rebuf_dur_max).

[0072] The current cached data is compared with the playback cache threshold corresponding to the stuck state, and the media data is played when the current cached data is greater than or equal to the playback cache threshold corresponding to the stuck state. When the current cached data is less than the playback cache threshold corresponding to the stuck state, the stuck data and the current cached data within the preset time window are returned to be re-acquired, and the playback cache threshold is re-determined, and the re-acquired current cached data is judged.

[0073] For the state of not starting to play, the preloaded data, the current cached data and the jamming data in the preset time window are obtained to calculate the playback cache threshold corresponding to the state of not starting to play, that is, the startup water level startup_buf_dur. Accordingly, the playback cache threshold can be determined by different calculation formulas according to the size of the preloaded data. Exemplarily, the amount of preloaded data preload_size is greater than the preload threshold startup_cache_size, which can be 500kb. The start type of the unstarted state is determined to be preloaded start, and the playback cache threshold is min(startup_buf_dur_preloaded_init*(1+startup_buf_inc_factor_preloaded*log(1+rebuf_count)), startup_buf_dur_preloaded_max), wherein startup_buf_dur_preloaded_init is the initial data corresponding to the preloaded start, startup_buf_inc_factor_preloaded is the growth parameter corresponding to the preloaded start, and rebuf_count is the number of freezes, i.e., a type of freeze data. Similarly, the number of freezes can also be freeze data determined by other methods. startup_buf_dur_preloaded_max is the preset maximum threshold corresponding to the preloaded start.

[0074] The data amount preload_size of the preloaded data is less than the preload threshold startup_cache_size, and the start type of the unstarted state is determined to be non-preloaded start, and the playback cache threshold is min(startup_buf_dur_nonpreloaded_init*(1+startup_buf_inc_factor_nonpreloaded*log(1+rebuf_count)), startup_buf_dur_nonpreloaded_max), startup_buf_dur_nonpreloaded_init is the initial data corresponding to the non-preloaded start, startup_buf_inc_factor_nonpreloaded is the growth parameter corresponding to the non-preloaded start, and startup_buf_dur_nonpreloaded_max is the preset maximum threshold corresponding to the non-preloaded start.

[0075] Compare the current cached data with the playback cache threshold corresponding to the not-started state, and play the media data if the current cached data is greater than or equal to the playback cache threshold corresponding to the not-started state. If the current cached data is less than the playback cache threshold corresponding to the not-started state, return to re-acquire the jam data, current cached data, and preloaded data within the preset time window, re-determine the playback cache threshold, and make a judgment on the re-acquired current cached data.

[0076] Figure 4 A schematic diagram of the structure of a playback control device provided by an embodiment of the present disclosure is shown in FIG. Figure 4 As shown, the device includes: a data acquisition module 210 , a playback buffer threshold determination module 220 and a playback module 230 .

[0077] The data acquisition module 210 is used to acquire the current cache data of the media data when the media data is not in a playback state, and acquire the freeze data of the playback device within a preset time window;
