<div dir="ltr">Hello,<div><br></div><div>I was using a screen capturing program called Kazam which captures my screen on Linux. It uses gstreamer to save the video. My computer crashed and now I'm left over with a .movie and .mux file that I canno't play or use. I recorded a one time event and really need this video feed.</div>
<div><br></div><div>I know the video results should be an MP4, I tried the following command.</div><div><br></div><div><div>gst-launch filesrc location=kazam_5bcdqb.movie.mux ! mp4mux name=mux ! filesink location=movie.mp4</div>
<div><br></div><div style>With result:</div><div>Setting pipeline to PAUSED ...</div><div>Pipeline is PREROLLING ...</div><div>Pipeline is PREROLLED ...</div><div>Setting pipeline to PLAYING ...</div><div>New clock: GstSystemClock</div>
<div>ERROR: from element /GstPipeline:pipeline0/GstMP4Mux:mux: Internal GStreamer error: negotiation problem. Please file a bug at <a href="http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer">http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer</a>.</div>
<div>Additional debug info:</div><div>gstqtmux.c(2496): gst_qt_mux_add_buffer (): /GstPipeline:pipeline0/GstMP4Mux:mux:</div><div>format wasn't negotiated before buffer flow on pad audio_00</div><div>Execution ended after 183817 ns.</div>
<div>Setting pipeline to PAUSED ...</div><div>Setting pipeline to READY ...</div><div>Setting pipeline to NULL ...</div><div>Freeing pipeline ...</div><div><br></div><div style>So my question is how can I convert this ".mux" file to mp4? I already contacted the original author of Kazam he send me here.
