◆ 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.
