) |
Rechunk audio PCM packets per AudioInterleaveContext->samples_per_frame and interleave them correctly.
The first element of AVStream->priv_data must be AudioInterleaveContext when using this function.
get_packet | function will output a packet when streams are correctly interleaved. |
compare_ts | function will compare AVPackets and decide interleaving order. |
