Description Dominik Kummer 2024-04-24 20:56:42 UTC

I want to open certain mp4 files which I recorded with Sony Actioncam. It always worked, but since the latest update I get an error: "Cannot open file /data/C0001.MP4"

This totally breaks everything I worked on.

This is most likely a packaging error. First check if there are any updates to MLT of FFmpeg. 
Then try opening one of these files in a terminal with FFmpeg and MLT:

ffplay /data/C0001.MP4
melt /data/C0001.MP4

What is the result of these commands.
Workaround would be to use the AppImage until things are resolved on your distro

Thanks for your quick answer! It was my fault of course :)
I got an outdated version of glslang installed on my system.
Thank you so much!!
