int(*)(AVFormatContext *, AVPacket *, AVPacket *, int get_packet,
int(*)(AVFormatContext *, const AVPacket *, const AVPacket *)  compare_ts 
)

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.

Parameters
get_packetfunction will output a packet when streams are correctly interleaved.
compare_tsfunction will compare AVPackets and decide interleaving order.
