AW: about gstreamer rtp

Hi, I forgot to mention that if you replace decodebin by qtdemux and h264parse followed by a capsfilter with stream-format=byte-stream you can save decoding and re-encoding your h264 stream. This will not only save you CPU but will also help to maintain the quality of the video. I am assuming that the mp4 file doesn’t contain audio.

Betreff: about gstreamer rtp

I am trying to stream vedio through this pipeline but it doesnot showing anything on launch screen

 gst-launch-1.0 -v filesrc location = 1.mp4 ! decodebin ! x264enc ! rtph264pay ! udpsink host=192.168.0.1 port=5000

after executing this this ,i am getting... like this...,

Setting pipeline to PLAYING ...
New clock: GstSystemClock

,and my client side pipeline is ...

gst-launch-1.0 -v udpsrc port=5000 caps="application/x-rtp, media=video, clock-rate=90000, encoding-name=H264, payload=96, ssrc=3394826012, timestamp-offset=2215812541, seqnum-offset=46353" ! rtph264depay ! decodebin ! videoconvert ! autovideosink sync=false,

but i am not getting any launch screen ..
