Functions
| Name | Description |
|---|---|
| OH_AVDemuxer * OH_AVDemuxer_CreateWithSource (OH_AVSource *source) | Creates an OH_AVDemuxer instance based on a source instance. |
| OH_AVErrCode OH_AVDemuxer_Destroy (OH_AVDemuxer *demuxer) | Destroys an OH_AVDemuxer instance and clears internal resources. |
| OH_AVErrCode OH_AVDemuxer_SelectTrackByID (OH_AVDemuxer *demuxer, uint32_t trackIndex) | Selects a track from which the demuxer reads sample data. |
| OH_AVErrCode OH_AVDemuxer_UnselectTrackByID (OH_AVDemuxer *demuxer, uint32_t trackIndex) | Deselects a track. The demuxer no longer reads data from a track after it is deselected. |
| OH_AVErrCode OH_AVDemuxer_ReadSample (OH_AVDemuxer *demuxer, uint32_t trackIndex, OH_AVMemory *sample, OH_AVCodecBufferAttr *info) | Reads the sample and related information from the specified track. (This function is deprecated from API version 11.) |
| OH_AVErrCode OH_AVDemuxer_ReadSampleBuffer (OH_AVDemuxer *demuxer, uint32_t trackIndex, OH_AVBuffer *sample) | Obtains the compressed frame and related information at the current position from the selected track. |
| OH_AVErrCode OH_AVDemuxer_SeekToTime (OH_AVDemuxer *demuxer, int64_t millisecond, OH_AVSeekMode mode) | Seeks to the specified time for all the selected tracks based on a seek mode. |
| OH_AVErrCode OH_AVDemuxer_SetMediaKeySystemInfoCallback (OH_AVDemuxer *demuxer, DRM_MediaKeySystemInfoCallback callback) | Sets an asynchronous callback for obtaining the media key system information. (This function is deprecated from API version 14.) |
| OH_AVErrCode OH_AVDemuxer_SetDemuxerMediaKeySystemInfoCallback (OH_AVDemuxer *demuxer, Demuxer_MediaKeySystemInfoCallback callback) | Sets an asynchronous callback for obtaining the media key system information. |
| OH_AVErrCode OH_AVDemuxer_GetMediaKeySystemInfo (OH_AVDemuxer *demuxer, DRM_MediaKeySystemInfo *mediaKeySystemInfo) | Obtains the media key system information. |
