<div>In your first pipeline it should be udpsink , not udpsrc.<br><br></div> <div>Another thing is that you are not properly setting up rtp packets of encoded data.</div> <div>So I think your pipelines should look like this;<br><br></div>gst-launch videotestsrc ! videoscale ! videorate ! video/x-raw-yuv,width=640,height=480,framerate=25/1 ! ffmpegcolorspace ! ffenc_mpeg4 ! rtpmp4vpay ! udpsink host=127.0.0.1 port=5000 <div> </div>gst-launch udpsrc port=5000 ! application/x-rtp,media=video,payload=100,clock-rate=100000000,encoding-name=MP4V-ES ! rtpmp4vdepay ! video/mpeg,width=640,height=480,framerate=25/1,mpegversion=4,systemstream=false ! avimux ! filesink location=test.avi<br> <br>And I could play this file using gst-launch playbin uri=file:///home/maemo/test.avi <br><br><br><br><div> </div> <div><br> </div> <div class="gmail_quote">On Thu, Nov 18, 2010 at 10:02 PM, Peter Innerhofer <span dir="ltr"><<a href="mailto:peter.innerhofer@student.tugraz.at" target="_blank">peter.innerhofer@student.tugraz.at</a>></span> wrote:<br> <blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0px 0px 0px 0.8ex; padding-left: 1ex;" class="gmail_quote">hello,<br><br>i have an issue with multiplexing and writing a stream to a file.<br><br>for example:<br> gst-launch v4l2src ! videoscale ! videorate !<br> video/x-raw-yuv,width=640,height=480,framerate=25/1 ! ffmpegcolorspace !<br>ffenc_mpeg4 ! avimux ! filesink location=test.avi<br><br>ok, this stream works fine. vlc can open and show codec meta data. but<br>now i send the stream to a udpsink and receive it.<br> <br>gst-launch v4l2src ! videoscale ! videorate !<br>video/x-raw-yuv,width=640,height=480,framerate=25/1 ! ffmpegcolorspace !<br>ffenc_mpeg4 ! udpsrc host=127.0.0.1 port=5000<br><br>gst-launch udpsrc port=5000 ! video/mpeg, width=(int)640,<br> height=(int)480, framerate=(fraction)25/1, mpegversion=(int)4,<br>systemstream=(boolean)false ! avimux ! queue ! filesink location=test.avi<br><br>now the video wont play in vlc and i cant open it in video editing<br>programs which are not based on gstreamer, they can't find any codec details<br> <br>ideas? what's wrong here, i have tried several multiplexer<br>(mpegtsmux,qtmux,ffmux_mp4), but its the same. shall i exit the pipeline<br>in an other way?
