enum SEIType  type,
enum AVCodecID  codec_id,
GetBitContext gb,

)

Decode a single SEI message.

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

Parameters
[in,out]gbGetBitContext 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]gbytea 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.
