ff_audio_rechunk_interleave()

int ff_audio_rechunk_interleave	(	AVFormatContext *	s,
		AVPacket *	out,
		AVPacket *	pkt,
		int	flush,
		int(*)(AVFormatContext *, AVPacket *, AVPacket *, int)	get_packet,
		int(*)(AVFormatContext *, AVPacket *, 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_packet	function will output a packet when streams are correctly interleaved.
compare_ts	function will compare AVPackets and decide interleaving order.
