Hello everybody,

Rendering in my kdenlive suddenly stopped working (probably after an automatic update), and it can't render anything. It doesn't matter what format I choose, rendering crashes with message like:
Requested output format 'mp4' is not a suitable output format

I tried to update ffmpeg, melt, codecs and most of other stuff that I can relate to the problem, but nothing helps.

I have no problems with playing any of video formats on my system, preview and all other functions in kdenlive work OK.

My system is openSUSE 13.1 x86_64 on Toshiba Satellite with CPU i3 3120M @ 2.5 GHz.

I would like to avoid upgrading my whole system for now, just to repair kdenlive rendering.

Thanks!

Do you use mlt from distro package or other binaries/builds? seems it is not linking properly with libavformat
Try to run the config wizard and see what codecs it has

Thank you for your suggestion, that directed me how to find the cause of the problem. Yes, when I checked in the wizard, all important codecs were missing. In the meantime, I upgraded the system to openSUSE 13.2, but the problem still persisted. Finally, I discovered that one of the libraries was installed from VideoLAN repository, and as soon as I replaced it with the same version from Packman, everything started to work

Thanks again!
