ff_isom_write_vpcc()

int ff_isom_write_vpcc	(	AVFormatContext *	s,
		AVIOContext *	pb,
		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.
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
