Hello there,
I’m tying to capture and play an rtp stream using omxh264enc an omxh264dec. Here are my pipelines.
gst-launch-1.0 nvarguscamerasrc ! ‘video/x-raw(memory:NVMM), width=1280, height=720, framerate=60/1’ ! nvvidconv ! omxh264enc control-rate=0 ! video/x-h264, stream-format=byte-stream ! rtph264pay mtu=1400 ! udpsink host=localhost port=5000
Using avdec_h264 i have no problems, besides bad performance when the bitrate goes up.
gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=H264,payload=96 ! rtph264depay ! h264parse ! queue ! avdec_h264 ! xvimagesink sync=true
If i try to use omxh264dec instead of avdec_h264 i got the following errors.

I’m doing something wrong, that’s for sure.
Thanks in advance!
