ff_av1_extract_obu()

int ff_av1_extract_obu	(	AV1OBU *	obu,
		const uint8_t *	buf,
		int	length,
		void *	logctx
	)

Extract an OBU from a raw bitstream.

Note

This function does not copy or store any bitstream data. All the pointers in the AV1OBU structure will be valid as long as the input buffer also is.
