I archived that. I am able now to play the video and it looks fine. The problem appears with the audio. I'm trying to send both video and audio to the Raspberry but the Faad (Free AAC decoder) doesn't work properly. This error appears: ERROR: from element /GstPipeline:pipeline0/GstFaad:faad0: Could not decode stream. Additional debug info: gstfaad.c(820):gst_faad_handle_frame (): /GstPipeline:pipeline0/GstFaad:faad0: Failed to init decoder from stream. Using the tail --gst-debug-level=2 in the receiver, it reveals warnings like " Invalid sample rate index 13" (from the aacparse) or Channel coupling not yet implemented (from audio decoder) or Bitstream value not allowed by specification. I attach you the pipelines I have used: Server: gst-launch-1.0 -v filesrc location=/home/carlos/Descargas/test.mp4 ! qtdemux name = dmux dmux.audio_0 ! aacparse ! rtpmp4gpay ! udpsink host=192.168.137.3 port=5004 dmux.video_0 ! queue ! h264parse ! avdec_h264 ! x264enc tune="zerolatency" threads=4 speed-preset=2 ! rtph264pay config-interval=2 mtu=4500 ! udpsink host=192.168.137.3 port=5002 Client (Raspberry): gst-launch-1.0 -v udpsrc uri=udp://<a href="http://192.168.137.3:5004" target="_blank">192.168.137.3:5004</a> caps="application/x-rtp,media=(string)audio" ! queue ! rtpmp4gdepay ! aacparse ! faad ! alsasink udpsrc uri=udp://<a href="http://192.168.137.3:5002" target="_blank">192.168.137.3:5002</a> caps ="application/x-rtp" ! rtpjitterbuffer ! queue ! rtph264depay ! h264parse ! omxh264dec ! autovideosink I will appreciate your help to solve the problem. -- View this message in context: <a href="http://gstreamer-devel.966125.n4.nabble.com/Could-not-decode-stream-error-with-GStreamer-tp4661571.html" target="_blank">http://gstreamer-devel.966125.n4.nabble.com/Could-not-decode-stream-error-with-GStreamer-tp4661571.html</a> Sent from the GStreamer-devel mailing list archive at Nabble.com. _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div> </div>
