Function Documentation

validate_sps()

bool cbs::validate_sps	(	const AVPacket *	packet,
		int	codec_id )

Validates the Sequence Parameter Set (SPS) of a given packet.

This function initializes a Coded Bitstream Context and reads the packet into a Coded Bitstream Fragment. It then checks if the SPS->VUI (Video Usability Information) is present in the active SPS of the packet. This is done for both H264 and H265 codecs.

Parameters

packet	The packet to validate.
codec_id	The ID of the codec used (either AV_CODEC_ID_H264 or AV_CODEC_ID_H265).

Returns

True if the SPS->VUI is present in the active SPS of the packet, false otherwise.
