Streaming from 'rtmpsrc' doesn't require rtph264depay or h264parse

Does anyone know why streaming RTMP with rtmpsrc doesn't require rtph264depay or h264parse in the pipeline? The below pipeline works just fine:

gst-launch-1.0 rtmpsrc location=rtmp://ip/test ! decodebin ! videoconvert ! autovideosink

And this pipeline does not:

gst-launch-1.0 rtmpsrc location=rtmp://ip/test ! rtph264depay ! h264parse ! decodebin ! videoconvert ! autovideosink

Solution

  • rtph264depay is for parsing RTP data. You are dealing with RTMP. Those to have absolute nothing in common. You re kinda lucky you don't need a parser as your decoder undestands the data as it comes from RTMP. Having the parser there won't hurt.
