Function Documentation

ff_h2645_sei_message_decode()

int ff_h2645_sei_message_decode	(	H2645SEI *	h,
		enum SEIType	type,
		enum AVCodecID	codec_id,
		GetBitContext *	gb,
		GetByteContext *	gbyte,
		void *	logctx
	)

Decode a single SEI message.

This function may either use gb or gbyte to decode the SEI message.

Parameters

[in,out]	gb	GetBitContext that needs to be at the start of the payload (i.e. after the payload_size bytes); it needs to be initially byte-aligned
[in,out]	gbyte	a GetByteContext for the same data as gb

Returns

< 0 on error, FF_H2645_SEI_MESSAGE_HANDLED if the SEI message has been handled or FF_H2645_SEI_MESSAGE_UNHANDLED if not.
