Description​

Depayloads RTP-encapsulated H.264 into a raw H.264 byte stream.

Place between an RTP source and a decoder. When enforce_h264_caps is true and any of h264_fps / h264_width / h264_height is set, the Node enforces those values on the depayloaded caps; otherwise it negotiates dynamically.
