Convert .mux to something readable (generated when kazam won't finish saving)

Asked by bert on 2013-01-04

Hello friends,

I recorded a video in my computer (Ubuntu 12.10) that cannot be recorded again. Kazam was not able to save it to mp4, but it left a .mux file. I tried playing the .mux with mplayer and xine, and I know that at least the sound is there and working!

maybe it's some sort of raw format (which by the way my players are not able to reproduce either). Anyway I run a channel and I need to upload this video by the end of the week.

I know it takes time to repair the bug so I am really asking for is a conversor! Something to fix the broken output, I know the information is there, it's just not readable. I need to edit it with kdenlive, so anything that works with it is fine for me.

Please consider! Thanks

Ricardo

Please I recorded a one time event and then my computer shutdown, how can we convert the mux and movie file to an mp4?

Please help!

.mux file is output from gstreamer, more precise from x264 encoder. Right now, I am not sure if it can be turned into a valid video file. I'll have to ask around on GStreamer mailing lists.

I ran into the same issue. I recorded a screen cast and then my computer over heated and crashed..... Now I have two files one a .movie and the other a .movie.mux.

I even tried to start a new session, pause it, delete the new files and rename the ones I am trying to recover to the new names. It combines them, but not correctly, so it won't play.

Same problem here...
Is there something news?

Same here, I recorded a mp4 - no sound, I pressed ''finish'' and closed Kazam normally. Found a .movie and a .mux file instead of the mp4.

I am running the Kazam version 1.4.3 on kubuntu 13.10

After some research I found a way to retrieve the corrupted video data - at least partly.
However, this solution requires Windows or Mac:

Some notes:
- I was able to do the trick by renaming my *.mux file to *.mp4
- My original recordings did not have any sound, I wanted to retrieve only video information.

I hope this helps a bit until a proper solution is found.

I see there hasn't been any update on this bug/program flaw.

Can one of the devs chime in on this if there is a native way to recover these .mux & .movie files by re-running kazam via terminal commands?

Tim Ritberg (xpert-reactos) said : #12

Maybe someone take the code, that save the mux in kazam to mp3 into a single script?
