Description

H264Depacketize Node — extracts H.264 NAL units from RTP packets.

Wraps rtph264depay. Insert between an RTP source (e.g. RTSPInput or a udpsrc) and an H.264 decoder. Optional caps enforcement injects framerate / geometry into the depayloaded stream when the upstream source is ambiguous.
