Abstract
The invention provides a method for adaptively selecting audio tracks, which comprises the following steps of: analyzing a transport stream to obtain an audio track information list, the audio track information at least comprising the number of audio tracks and an audio track audio coding format; acquiring audio coding format support information in the audio track information list; wherein the support information is acquired through a first interface; and selecting an audio track supported by an audio coding format in the audio track information list for playing. In addition, the invention further provides a device for adaptively selecting the audio tracks and a storage medium. According to the audio track self-adaptive selection method and device and the storage medium provided by the invention, the audio track number and the audio coding format of the audio track are obtained when the transport stream is analyzed, the audio track information list is obtained, the support information in the audio track information list is obtained through the first interface, and the audio track is selected for playing according to the support information. The problem that the audio cannot be played due to the audio coding format is avoided, the user experience is good, and the application range is wide.
Description
technical field [0001] The invention relates to the technical field of adaptively selecting audio tracks, in particular to a method, device and storage medium for adaptively selecting audio tracks. Background technique [0002] When the user uses the software to play multimedia, it plays according to the audio track in the transport stream (Transport Stream, TS), but the TS stream usually contains multiple audio tracks, and there are many audio encoding formats supported by each audio track. Types, such as WMA format (Windows Media Audio, WMA), Digital Theater Systems (Digital Theater Systems, DTS), MPEG (Moving Picture Experts Group, MPEG), MP3 (MPEG Audio Layer-3), Dolby Digital's AC3 (Audio Coding3 , AC3), AC3_PLUS, Advanced Audio Coding (AAC), Pulse Code Modulation (Pulse Code Modulation, PCM), Adaptive Differential Pulse Code Modulation (Adaptive Differential Pulse Code Modulation, ADPCM), RAAC (Real Application Clusters, RAAC ), COOK, lossless compression audio format...
