Функции

av_dirac_parse_sequence_header()

int av_dirac_parse_sequence_header	(	AVDiracSeqHeader **	dsh,
		const uint8_t *	buf,
		size_t	buf_size,
		void *	log_ctx
	)

Parse a Dirac sequence header.

Аргументы

dsh	this function will allocate and fill an AVDiracSeqHeader struct and write it into this pointer. The caller must free it with av_free().
buf	the data buffer
buf_size	the size of the data buffer in bytes
log_ctx	if non-NULL, this function will log errors here

0 on success, a negative AVERROR code on failure
