Description

H264CapsFixup Node — normalizes ambiguous H.264 RTP caps before depayload.

Some upstream RTP sources negotiate caps that omit framerate or frame size, which trips up downstream stages that need them. This Node patches in fallback values so the rest of the pipeline can negotiate cleanly. Insert between an RTP source and H264Depacketize when caps from the source are unreliable.
