[0053] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0054] It should be noted that the terms "first", "second", and the like in the embodiments of the present application are only used for the purpose of description and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection claimed by the present application.

[0055] In the description of the present application, it should be understood that the numerical reference number before the step does not indicate the order of execution of the steps before and after the step, but only for the convenience of describing the present application and distinguishing each step, therefore it should not be understood as a limitation of the present application.

[0056] First, the explanation of the terms involved in the present application is provided:

[0057] Encapsulation format: generally called encapsulation format or container format, is a format used to store audio and video data.

[0058] MP4: MP4 or called MPEG-4 Part 14 is a standard digital multimedia container format. The extension of MPEG-4 Part 14 is.mp4, mainly used to store digital audio and digital video, but also can store subtitles and still images. Because it can accommodate video streams that support bit streams (such as advanced video encoding), it is a streaming media. The format of MP4 stores various data in units of Box, and a Box can contain another Box.

[0059] Track: Common media files contain audio and video, and the audio and video are generally called audio track and video track. Generally, a media file contains only one audio track and one video track, but many encapsulation formats support multiple tracks.

[0060] MediaSource: Media Source Extensions API or MSE, is a media playback interface provided by the browser to the developer, which allows playing audio and video files generated by program code, instead of only playing audio and video from files or network addresses.

[0061] MIME Type: Multipurpose Internet Mail Extensions (MIME) is an Internet standard. Browsers usually use MIME types (not file extensions) to determine how to handle URLs, so it is important for web servers to add the correct MIME type in the response header. If the configuration is not correct, the browser may not be able to parse the file content, the website will not work properly, and the downloaded file will be misprocessed. In MediaSource, the MIME Type is needed to tell the browser the current playing audio and video format.

[0062] Secondly, in order to facilitate the understanding of the technical personnel in the art, the related art is explained as follows:

[0063] The MP4 format container supports storing multiple audio and video tracks. Most local players support switching the currently playing track at any time when playing multi-track media files.

[0064] In the web browser standard, track switching can be performed by controlling the enabled attribute of audioTracks and videoTracks, but the new version and most browser kernels on the market do not support this function.

[0065] In view of the poor support of browsers for multi-track media format, most solutions store tracks in multiple media files, so that each media file has only one audio or video track. Each time the video track file and the audio track file to be played are downloaded, and then played through the MediaSource interface provided by the browser.

[0066] Although multi-track media is an industry standard, it is only supported by a small number of browsers, so it is currently only used in the scene of local playback. When playing multimedia video in the browser, although multiple track media files can be preprocessed into multiple media files on the server to realize playback and track switching, there is a big difference between the preprocessing and playback logic and the ordinary media playback logic. The difference is that the previous playback media only needs to download one media file, and after using this scheme, at least two media files need to be downloaded, so the use cost is increased, and it is difficult to reuse the existing server and client system.

[0067] To this end, the embodiment of the present application provides a technical solution of switching of a media file. In the technical solution, track basic information corresponding to a multimedia file is acquired; wherein the multimedia file corresponds to a plurality of media files of different tracks, and the track basic information contains a mark bit used for indicating a main track currently required to be played; in response to a switching event of the played media file, a first media file required to be played is determined from the plurality of media files of different tracks, and the track basic information is adjusted so that the main track in the mark bit points to the first media file; and the played media file in the embedded player of the switching webpage is controlled according to the adjusted track basic information. When the played media file needs to be switched, the first media file required to be played is determined, and the track basic information is modified so that the main track in the mark bit points to the first media file. It can be understood that the track basic information contains track information corresponding to each media file, and each track information always points to the position of the media file corresponding to the track, therefore, modifying the track basic information means changing the mapping relationship between the track and the media file, for example, modifying the track number or data mapping address corresponding to the first media file can change the mapping relationship between the track and the media file, so that the switching of the media file can be realized by adjusting the track basic information in real time before playing the multimedia file, without preprocessing the media file, without supporting playing and switching of the multi-track media on the embedded player of the webpage supporting the multi-track media, and realizing the same seamless switching of the audio or video track as the local player in the browser, without the situations such as lag, black screen, and jump of the playing time. Details are shown below.

[0080] Embodiment One

[0081] FIG. 2 schematically shows a flowchart of a switching method of a media file according to Embodiment One of the present application.

[0082] As shown in FIG. 2, the switching method of the media file can include steps S202-S206, wherein:

[0083] In step S202, track basic information corresponding to a multimedia file is acquired; wherein the multimedia file corresponds to a plurality of media files of different tracks, and the track basic information contains a mark bit for indicating a main track currently required to be played;

[0084] In step S204, in response to a switching event of the played media file, a first media file required to be played is determined from the plurality of media files of different tracks, and the track basic information is adjusted so that the main track in the mark bit points to the first media file;

[0085] In step S206, the played media file in the embedded player of the switching webpage is controlled according to the adjusted track basic information.

[0086] The switching method of the media file provided by the present embodiment can be understood as follows: when the played media file needs to be switched, a first media file required to be played is determined, and the track basic information is modified so that the main track in the mark bit points to the first media file. It can be understood that the track basic information contains track information corresponding to each media file, and each track information always points to the position of the media file corresponding to the track. Therefore, modifying the track basic information means changing the mapping relationship between the track and the media file. For example, modifying the track number or data mapping address corresponding to the first media file can change the mapping relationship between the track and the media file. Thus, the switching of the media file can be realized by adjusting the track basic information in real time before playing the multimedia file, without preprocessing the media file. The switching of the multi-track media can be realized on the embedded player of the webpage without supporting the multi-track media, and the seamless switching of the audio or video track in the browser can be realized as in the local player, without the situations such as lag, black screen, and jump of the playing time.

[0087] The steps S202-S206 and optional other steps will be described in detail below in combination with FIG. 2.

[0088] In step S202, track basic information corresponding to a multimedia file is acquired; wherein the multimedia file corresponds to a plurality of media files of different tracks, and the track basic information contains a mark bit for indicating a main track currently required to be played;

[0089] The multimedia file corresponds to a plurality of different track media files, such as two video tracks and two audio tracks, which can be packaged in a multimedia file and played in the embedded player of the webpage.

[0090] In the embodiment, the track basic information can be parsed from the track header of the multimedia file, and the track basic information includes the track information corresponding to each media file. The track information of the media file always points to the position of the data area corresponding to the track. In addition, the track basic information can also include a flag bit, which is used to indicate the main track currently required to be played. The main track is the track used by default by the player.

[0091] Specifically, a processing program for switching media files is deployed in the embedded player of the webpage. The processing program can parse the encapsulation format of the multimedia file. Different encapsulation formats have different storage structures for multi-track files, but most formats include a "track information area" and a "data area". For example, FIG. 3 shows a module block diagram for switching media files in MP4 format. In FIG. 3, the multimedia file in MP4 format is taken as an example. Each area is called a Box in this format. The track basic information is stored through TKHD and TFHD Boxes. MDAT is an audio and video data block. The track and data can be associated through TKHD and TFHD Boxes. It should be noted that the multimedia file in MP4 format also includes other types of Boxes, which are omitted in FIG. 3. TKHD includes a flag bit, which is used to indicate whether the current track is the main track. At the same time, if TFHD exists, TKHD will associate the track number (track_id) with the TFHD of the same track number.

[0092] In step S204, in response to the switching event of the played media file, a first media file required to be played is determined from the plurality of different track media files, and the track basic information is adjusted so that the main track in the flag bit points to the first media file.

[0093] Specifically, by deploying a processing program for implementing switching of media files in the embedded player of the webpage, when the embedded player of the webpage receives a switching event for the played media file, the processing program determines a first media file to be played from the plurality of media files of different tracks in response to the switching event for the played media file, and adjusts the track base information so that the main track in the mark bit points to the first media file. For example, the main track in the mark bit is directed to the first media file by modifying the track number in the track base information or the mapping address of the track information and the data area. The main track in the mark bit can also be directed to the first media file by deleting the non-main information (the track information corresponding to the media file of the track other than the first media file) or replacing the Box type with a Box type ignored by the player, such as the FREE Box type. In this way, even if the media file of the track still exists in the data area, the player does not know the existence of the track. At this time, the MIME Type type of the MediaSource can be set like a normal single-tone video, so that the embedded player of the webpage can directly play the first media file.

[0094] In step S206, the played media file in the embedded player of the webpage is controlled according to the adjusted track base information.

[0095] In the embodiment, the embedded player of the webpage reads the main track recorded in the mark bit field and acquires the multimedia file corresponding to the main track to play the multimedia file each time the multimedia file is played. Specifically, after the embedded player of the webpage completes the playing of the media file, the mark bit in the track base information is re-read, and then the key frame of the media file corresponding to the main track is acquired according to the mark bit. The key frame is sent to the MediaSource interface of the embedded player of the webpage, and the media file corresponding to the main track is played by using the MediaSource interface.

[0096] Specifically, adjusting the track base information includes two cases. One is to modify the mapping relationship between the track and the data area in the track information so that the main track in the mark bit points to the first media file. The other is to shield the non-main information. In this case, since the player can only read the first media file for playing, the main track in the mark bit will also point to the first media file. When the multimedia file is played, the first media file can be acquired according to the adjusted track base information to control the played media file in the embedded player of the webpage.

[0097] In an optional embodiment of the present application, the adjusting the track base information so that the main track in the mark bit points to the first media file comprises:

[0098] determining first track information corresponding to the first media file from the track base information, wherein the first track information comprises a track number; and adjusting the track number in the first track information according to the main track in the mark bit, so that the main track in the mark bit points to the first media file.

[0099] In the embodiment, when switching the media file is needed, a processing program for switching the media file is deployed in the embedded player of the webpage, the processing program determines first track information corresponding to the first media file from the track base information, wherein the first track information comprises a track number, and the track number is a unique identification code of the track, and then adjusts the track number in the first track information according to the main track in the mark bit, so that the main track in the mark bit points to the first media file.

[0100] In an optional embodiment of the present application, the adjusting of the mapping relationship so that the main track in the mark bit points to the first media file comprises:

[0101] determining first track information corresponding to the first media file from the track base information, wherein the first track information comprises a data mapping address; and adjusting the data mapping address in the first track information according to the main track in the mark bit, so that the main track in the mark bit points to the first media file.

[0102] In the embodiment, when switching the media file is needed, a processing program for switching the media file is deployed in the embedded player of the webpage, the processing program determines first track information corresponding to the first media file from the track base information, wherein the first track information comprises a track number, and the track number is a unique identification code of the track, and then adjusts the track number in the first track information according to the main track in the mark bit, so that the main track in the mark bit points to the first media file.

[0103] In an optional embodiment of the present application, the adjusting of the track base information so that the main track in the mark bit points to the first media file comprises:

[0104] determining a second media file other than the first media file from the plurality of media files of different tracks; determining second track information corresponding to the second media file from the track base information, and deleting the track information corresponding to the second media file, so that the main track in the mark bit points to the first media file.

[0105] In the embodiment, when it is needed to switch media files, a second media file other than the first media file in the plurality of media files with different tracks is determined by a processing program, wherein the second media file contains one or more media files; then, second track information corresponding to the second media file is determined from track basic information, and the track information corresponding to the second media file is deleted, so that the main track in the mark bit points to the first media file. Since the embedded player of the webpage performs a reading operation on data according to the track information, after the track information corresponding to the second media file is deleted, even if the data of the track still exists in the data area, the embedded player of the webpage does not know the existence of the track, and the MIME Type type of the MediaSource can be set like a normal single-tone video.

[0106] In an optional embodiment of the present application, the adjusting the track basic information so that the main track in the mark bit points to the first media file comprises:

[0107] determining a second media file other than the first media file in the plurality of media files with different tracks; determining second track information corresponding to the second media file from the track basic information, wherein the second track information contains a Box type; and adjusting the Box type in the second track information based on a preset type, so that the main track in the mark bit points to the first media file.

[0108] The Box type refers to the data type of a basic unit of a media encapsulation format. The preset type refers to some data encapsulation structures that are ignored / not supported by the embedded player of the webpage, for example, a FREE Box type.

[0109] In the embodiment, when it is needed to switch media files, a second media file other than the first media file in the plurality of media files with different tracks is determined by a processing program, wherein the second media file contains one or more media files; then, second track information corresponding to the second media file is determined from track basic information, and the track information corresponding to the second media file is deleted, so that the main track in the mark bit points to the first media file. Since the embedded player of the webpage performs a reading operation on data according to the track information, after the track information corresponding to the second media file is deleted, even if the data of the track still exists in the data area, the embedded player of the webpage does not know the existence of the track, and the MIME Type type of the MediaSource can be set like a normal single-tone video.
