Pipeline syntax for decoding h264 video from pcap containing RTP/UDP

[user1890246781234]

I'm looking to get a sanity check on my pipeline syntax for extracting a
video file from a wireshark pcap containing rtp/udp for the video.

Here is the command I'm using and the error I'm receiving.


$ gst-launch filesrc location=udponly.pcap ! pcapparse !
application/x-rtp,media=video,clock-rate=90000,payload=123,encoding-name=H264
! rtph264depay ! decodebin ! autovideosink      Setting pipeline to PAUSED
...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal
data flow error.
