Function Documentation

ff_isom_write_vpcc()

int ff_isom_write_vpcc	(	AVFormatContext *	s,
		AVIOContext *	pb,
		const uint8_t *	data,
		int	len,
		AVCodecParameters *	par
	)

Writes VP codec configuration to the provided AVIOContext.

Parameters

s	address of the AVFormatContext for the logging context.
pb	address of the AVIOContext where the vpcC shall be written.
data	address of a data array which contains coded bitstream data from which codec information can be extracted. May be NULL.
len	length of the data array.
par	address of the AVCodecParameters which contains codec information.

Returns

>=0 in case of success, a negative value corresponding to an AVERROR code in case of failure
