[0026] figure 1 It is a schematic flowchart of a method for playing an audio-visual file provided by the first embodiment of the present invention, which specifically includes the following steps:

[0027] Step 11. Receive a request for playing the audio-visual file, and execute step 12.

[0028] For example, when the user clicks or touches the play button of the multimedia connection device (such as a Blu-ray disc player), the play request is sent to the audiovisual file play device in the form of an instruction. Wherein, the video file playback request carries the content to be played (such as a video disc, video) or the location of the content (such as an IP address, etc.), so that the content to be played by the user can be quickly found during subsequent playback.

[0029] Step 12: Obtain the playback format supported by the audio-visual file, and execute step 13.

[0030] Among them, the playback format includes audio formats (such as Chinese + PCM encoding format, English + PCM...

[0073] figure 2 It is a schematic flowchart of a method for playing an audiovisual file provided by the second embodiment of the present invention, which specifically includes the following steps:

[0074] Step 21: Receive a request for playing an audio-visual file, and execute step 22.

[0075] For details, refer to the detailed description of this step in the foregoing embodiment, which will not be repeated here.

[0076] Step 22: Obtain the video and audio files and the playback format supported by the playback device respectively, and execute step 23.

[0077] For example, by reading the audio code stream contained in the disc or video file, the audio code stream contains the audio format supported by the disc or video, and the audio code stream data is parsed to obtain the encoding format information and language, thereby determining the disc Or the audio format supported by the video. For example, the audio format supported by the acquired audio-visual file is English+AAC enco...

[0096] image 3 It is a schematic flowchart of a multimedia playback method provided by the third embodiment of the present invention, which specifically includes the following steps:

[0097] Step 31: Receive an audiovisual file playback request, and execute step 32.

[0098] Step 32: Receive the playback format selected by the user, and execute step 33.

[0099] Step 33: Output the data code stream of the video file corresponding to the playback format selected by the user to a playback device, so that the playback device can play the video file, and step 34 is executed.

[0100] Step 34: Update the play format sorting table.

[0101] For example, taking the audio format sorting table as an example, the audio format selected by the user is English + VQF encoding format, then the historical selection times corresponding to the English + VQF encoding format in the audio format sorting table will be updated. Take the above table 7 as an example , The number of historical selections corr...

Abstract

The embodiment of the invention discloses a video and audio file playing method and device. The method includes receiving an audio-visual file playback request; obtaining the playback format supported by the audio-visual file; querying the playback format sorting table, the priority order of the playback format is recorded in the playback format sorting table; determining the playback format in the playback format sorting table Whether to include the playback format supported by the audio-visual file, if included, select the playback format with the highest priority from the playback formats supported by the audio-visual file according to the playback format sorting table; The data code stream of the video file is output to the playback device, so that the playback device plays the video file according to the data code stream. The embodiment of the present invention can automatically select the playback format for the user according to the playback format sorting table, so that the video file can be played Smarter.

Description

Technical field [0001] The embodiments of the present invention relate to multimedia technology, and in particular to a method and device for playing audio-visual files. Background technique [0002] With the development of multimedia technology, there are more and more types of playback formats supported by video and audio files (for example, audio formats include combinations of audio encoding formats and recording languages, and subtitle languages), and playback devices are also compatible with multiple playback formats. Take audio format as an example. Common audio formats include Chinese + Digital Theatre System (DTS) format, English + DTS encoding format, Korean + DTS encoding format, Chinese + Dolby encoding format, and English + dolby encoding Format, Chinese + Pulse Code Modulation (PCM) format, English + PCM coding format and Japanese + PCM coding format, etc.; take subtitle languages ​​as an example, including Chinese, English, French, etc. Different people have diffe...
