omxh264enc framerate=0/1
When I use this Gstreamer pipeline:
gst-launch-1.0 videotestsrc ! "video/x-raw,width=640,height=480,framerate=24/1" ! videoconvert ! omxh264enc ! h264parse ! rtph264pay ! udpsink port=9000
With this receiver pipeline:
gst-launch-1.0 -v udpsrc port=9000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! rtph264depay ! avdec_h264 ! videoconvert ! xvimagesink
avdec_h264 outputs that framerate=(fraction)0/1
Gstreamer isn't able to determine the framerate, because of this a lot of (RTP) players aren't able to play this RTP stream.
When I try this pipeline with the same receiver pipeline but with x264enc encoder:
gst-launch-1.0 videotestsrc ! "video/x-raw,width=640,height=480,framerate=24/1" ! videoconvert ! x264enc ! h264parse ! rtph264pay ! udpsink port=9000
The output of the same receiver pipeline is this:

Redistribute latency... `
Here you can see that the framerate is set correctly.
I think there is some missing information in the omxh264enc H264 stream. How can I fix this?
