<div dir="ltr"><div><div><div><div>I telecommute to work, and my office has recently started streaming the contents of our video projector during meetings so folks like I can see what is being projected. I don't know too many details of their setup, except that they are using VLC to capture the projector stream and are sending out over a VNC. I'm told the stream is an asf-mux of wmv2 video.<br>
<br></div>At my end the data shows up at <a href="http://localhost:8080">http://localhost:8080</a>. I can watch the video by running:<br><br></div>vlc <a href="http://localhost:8080">http://localhost:8080</a><br><br></div>
so that I know I'm getting the data correctly. However, I would like to figure out how to decode this stream via gstreamer so I could play it on my video wall.<br><br></div>So far my every attempt at this has failed. The best I've been able to accomplish is this:<br>
<br><span style="font-family:courier new,monospace">$ gst-launch-1.0 playbin uri=<a href="http://localhost:8080">http://localhost:8080</a><br>Setting pipeline to PAUSED ...<br>Pipeline is PREROLLING ...<br>buffering... 0% <br>

Does anyone have other ideas of what I could try?<br>
