I'm on jessie (pure jessie, not a mix with wheezy) and i did nothing special except apt-get update and apt-get dist-upgrade and then the following pipeline works perfectly : (receives h264 from a PC)
gst-launch-1.0 -v udpsrc port=5000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264" ! rtpjitterbuffer ! rtph264depay ! queue ! h264parse ! queue ! omxh264dec !
queue ! glimagesink
this did not work before.
Now as far as i can notice:
eglglessink element is available and works on wheezy but not on jessie.
