copied!<p><b>Edit</b><br/> I stopped using VLC and switched to <a href="http://www.google.be/search?q=GMax+FLV+Encoder+3.8.0.0" rel="nofollow noreferrer">GMax FLV Encoder</a>. It does a much better job IMO.</p> <p><b>Original post</b><br/> I am sending my desktop (screen) as an H264 video stream to another machine that saves it to a file using the follwoing command lines:</p> <p>Sender of the stream:</p> <pre><code>vlc -I dummy --sout='#transcode{vcodec=h264,vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' </code></pre> <p>Receiver of the stream:</p> <pre><code>vlc -I rc rtp://@:4444 --sout='#std{access=file,mux=ps,dst=/home/user/output.mp4}' --ipv4 </code></pre> <p>This works, but there are a few issues:</p> <ul> <li>The file is not playable with most players.</li> <li>VLC is able to playback the file but with some weirdness:</li> <li>=> it takes about 10 seconds before the playback actually begins.</li> <li>=> seeking doesn't work.</li> </ul> <p>Can someone point me in the right direction on how to fix these issues?</p> <p><b>EDIT</b>: I made a little progress.</p> <p>The initial delay in playback is because the player is waiting for a keyframe. By forcing the sender of the stream to create a new key-frame every 4 seconds I could decrease the delay:</p> <pre><code>:screen-fps=10 --sout='#transcode{vcodec=h264,venc=x264{keyint=40},vb=512,scale=0.5} :rtp{mux=ts,dst=192.168.0.1,port=4444}' </code></pre> <p>The seeking problem is not solved however, but I understand it a little better. The RTP stream is saved as a file in its original streaming format, which is normally not playable as a regular video file. VLC manages to play this file, but most other players don't. So I need to convert it to a regular video file. I am currently investigating whether I can do this with ffmpeg if I provide it with an SDP file for the recorded stream.</p> <p>All help is welcome!</p>
