Now I want to stream different files, for example a mp4 file encoded h264. I<br>
run next command on the server:<br>
//new-server<br>
gst-launch -v filesrc location=h264codec_mp4format.mp4 ! ffenc_mpeg4 !<br>

But I get this error:<br>

<br>
I think I have to set the frame size, could you help me with this?<br>
And in general, is there a way to find out what capabilities has a file, for<br>
example h264codec_mp4format.mp4?<br></blockquote><div><br></div><div>On Linux you can use mediainfo for a quick summary of the media file.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
