[0122] It can be seen that this optional embodiment can determine the target assisting transcoding device based on the current device status and idle computing power information of the pre-configured assisting transcoding device, and the transcoding assistance request information, which is conducive to improving the comprehensiveness, integrity and rationality of the target assisting transcoding device determination method, and further conducive to improving the accuracy and reliability of the determined target assisting transcoding device, thereby facilitating improving the subsequent video transcoding accuracy and efficiency based on the target assisting transcoding device, and reducing the occurrence of poor video transcoding effects due to inappropriate configuration of the assisting transcoding device.

[0123] In another optional embodiment, the second processing end determines an assisting transcoding device that meets a preset video transcoding condition from all assisting transcoding devices according to the current device state and idle computing power information of each assisting transcoding device and the transcoding assistance request information, as the target assisting transcoding device, which may include:

[0124] The second processing end determines, according to the current device state of each assisting transcoding device, a first assisting transcoding device that meets a preset idle / low power consumption state condition from all the assisting transcoding devices;

[0125] Determining, according to the idle computing power information and the transcoding assistance request information of each first transcoding assisting device, a second transcoding assisting device that meets a preset transcoding capability condition from all the first transcoding assisting devices;

[0126] A target assisting transcoding device is determined according to all the second assisting transcoding devices.

[0127] Further optionally, the above-mentioned assisting transcoding devices that meet the preset idle / low power consumption state conditions and meet the preset transcoding capability conditions are determined from all assisting transcoding devices. For example: the assisting transcoding devices that are idle and have idle computing power to support video transcoding of this type of format (i.e., can complete the transcoding requirements of the video to be transcoded) are determined from all assisting transcoding devices. The embodiments of the present invention are not limited to this.

[0128] Furthermore, it is necessary to determine the assisting transcoding device that meets the preset transcoding capability conditions. For example: the higher the resolution of the transcoded video, the higher the required device performance, the higher the frame rate requirement, the higher the hardware and network speed requirements; for example, when the frame rate of 4k or 8k original video is converted to 1080p, the CPU and network speed requirements are higher than those of 1080p original video to 720p video, which is not limited in the embodiments of the present invention.

[0129] Further optionally, the determining of the target assisting transcoding device according to all the second assisting transcoding devices may include:

[0130] All second assisting transcoding devices are determined as target assisting transcoding devices.

[0131] It can be seen that this optional embodiment can determine the target assisting transcoding device through two levels of device status conditions and transcoding capability conditions, which is conducive to improving the progressiveness and comprehensiveness of the target assisting transcoding device determination method, and further conducive to improving the diversity and pertinence of the screening conditions for the target assisting transcoding device, thereby helping to improve the accuracy and reliability of the determined target assisting transcoding device.

[0132] In another optional embodiment, the second processing end controls each target assisting transcoding device to perform a corresponding video transcoding operation according to each video transcoding task information to obtain a video transcoding result corresponding to the video to be transcoded, which may include:

[0133] The second processing end controls each target assisting transcoding device to perform corresponding video transcoding operations on the corresponding video split segments according to each video transcoding task information, and obtains the segment transcoding results of each video split segment;

[0134] For each segment transcoding result, according to the determined first transcoding time information of the segment transcoding result, a corresponding transcoding segment splitting operation is performed on the segment transcoding result to obtain one or more transcoding split contents corresponding to the segment transcoding result, and second transcoding time information of each transcoding split content is determined;

[0135] The second transcoding time information of each transcoded split content is sent to the first processing end.

[0136] Optional, for example: split the original video, assign transcoding tasks to multiple assisting devices for transcoding, and split the transcoding results after successful transcoding of the assisting device. There is no need to send the successfully transcoded video stream to the NAS. After receiving the split result, the NAS will mark the corresponding fragment source address in the m3u8 file as the assisting device address according to the fragment content. When the player plays the video later, it can directly request the video stream from the assisting device; further example: transfer one minute or tens of seconds of content to the assisting device for transcoding, then the time point of transcoding is clear. After successful transcoding, it will indicate that the current video specifies the time content fragment to request the assisting device, which is not limited in the embodiment of the present invention.

[0137] Optionally, the first transcoding time information may be the overall time information corresponding to the fragment transcoding result, and the second transcoding time information may be the specific transcoding time information of each transcoded split content, which is not limited in the embodiment of the present invention.

[0138] Optionally, the above-mentioned first transcoding time information of the determined fragment transcoding result is used to perform a corresponding transcoding fragment splitting operation on the fragment transcoding result to obtain one or more transcoding split contents corresponding to the fragment transcoding result. For example: according to the transcoding time of the fragment transcoding result, the fragment transcoding result is further split into fragments to obtain one or more transcoding split contents corresponding to the fragment transcoding result, which is not limited in the embodiment of the present invention.

[0139] It can be seen that this optional embodiment is able to perform video transcoding operations, transcoding result splitting operations and transcoding time determination operations on the video split segments, which is conducive to improving the comprehensiveness and integrity of the method for determining the video transcoding results of the video to be transcoded, and further conducive to improving the transcoding accuracy, pertinence and efficiency of the video split segments, thereby helping to improve the accuracy and reliability of the segment transcoding results of the video split segments, and further conducive to improving the accuracy and comprehensiveness of the video transcoding results of the video to be transcoded.

[0140] In yet another optional embodiment, after the second processing end sends the second transcoding time information of each transcoded split content to the first processing end, the method may further include the following operations:

[0141] The first processing end determines the video playback file corresponding to the video to be transcoded, and determines the device address information of the target assisting transcoding device corresponding to each segment transcoding result;

[0142] According to the device address information of each segment transcoding result, each transcoding split content and its corresponding second transcoding time information, a corresponding request address marking operation is performed on the video playback file to obtain a request address marking result;

[0143] The request address marking result is used to determine the target assisting transcoding device of the video to be transcoded and obtain the video transcoding content of the video to be transcoded through the target assisting transcoding device to complete the transcoding and playback of the video to be transcoded.

[0144] Optionally, the video playback file corresponding to the video to be transcoded may be an m3u8 file, or other files capable of implementing a video playlist, which is not limited in the embodiment of the present invention.

[0145] Optionally, the fragment transcoding result of each video split segment (that is, the content obtained by fragment transcoding) is stored in the target assisting transcoding device that transcodes the video split segment, and the corresponding fragment content request address (that is, the address of the target assisting transcoding device) is marked in the finally generated m3u8 file. The corresponding fragment source address is marked in the m3u8 file as the device address of the corresponding target assisting device according to the fragment content. When the subsequent player plays the video, it can directly request the video stream from the assisting device, which is not limited to the embodiment of the present invention.

[0146] Further, for example: after the target assisting device A successfully transcodes the 10s-15s video, it will be marked in the m3u8 file that the 10s-15s video content is requested from the address of the target assisting device A. When the player plays the video subsequently, it reads directly from the address of the target assisting device A without reading from the NAS itself. This is not done in the embodiment of the present invention.

[0147] It can be seen that this optional embodiment can provide a request address marking function for the video playback file of the video to be transcoded to achieve subsequent video playback, which is beneficial to improving the comprehensiveness and integrity of the transcoding and playback method of the video to be transcoded, and further beneficial to improving the efficiency, convenience and accuracy of obtaining the transcoding results of the video to be transcoded, thereby helping to improve the playback efficiency and playback convenience of the video to be transcoded, and can also reduce the data space storage occupancy of the first processing end (i.e., the NAS machine).

[0148] In yet another optional embodiment, the original video parameter information includes at least original video format information, original resolution information, and original frame rate information; the target video parameter information includes at least target transcoding resolution information and target transcoding frame rate information;

[0149] Further optionally, before the first processing end sends the transcoding assistance request information to the second processing end, the method may further include the following operations:

[0150] The first processing end determines a video to be transcoded that needs video assisted transcoding;

[0151] Perform corresponding video format transcoding and reading operations on the video to be transcoded to obtain original video format information of the video to be transcoded, and perform corresponding picture quality and resolution frame rate analysis operations on the video to be transcoded to obtain original resolution information and original frame rate information of the video to be transcoded;

[0152] According to the transcoding request information received from the user for the video to be transcoded, the target transcoding resolution information of the video to be transcoded is determined, and according to the target transcoding resolution information and the determined network speed information of the assisting device, the target transcoding frame rate information of the video to be transcoded is determined.

[0153] Optionally, the video to be transcoded may include, but is not limited to, one or more of original video files, video streams, other forms of videos, etc., which is not limited in the embodiment of the present invention.

[0154] Optionally, the above-mentioned corresponding video format transcoding and reading operations, picture quality and resolution frame rate analysis operations are performed on the transcoded video. For example, the video to be transcoded is decoded into uncompressed original video frames and audio data to obtain original video format information, original resolution information and original frame rate information, which is not limited to the embodiments of the present invention.

[0155] Optionally, the transcoding request information output by the user for the video to be transcoded may be transcoding request parameter information sent by the user operating the client, which is not limited in the embodiment of the present invention.

[0156] Optionally, the determined network speed information of the assisting device may be understood as the current network speed information of the assisting transcoding device, which is not limited in the embodiment of the present invention.

[0157] It can be seen that this optional embodiment can provide a method for determining original video parameter information and a method for determining target video parameter information, which is conducive to improving the comprehensiveness and rationality of the method for determining original video parameter information, and further conducive to improving the accuracy and reliability of the determined original video parameter information. In addition, it is also conducive to improving the comprehensiveness and rationality of the method for determining target video parameter information, and further conducive to improving the accuracy and reliability of the determined target video parameter information, thereby facilitating improving the accuracy and reliability of the transcoding effect for the video to be transcoded.
