seems like an ffmpeg error, '-f null' should help

Thank you Selur. 

I installed the same distro onto another drive and your dev build worked out of the box. Nice work.

How do I go about adding ffmpeg commands into hybrid, can I do it inside hybrid itself?

Good to know. Thanks for testing.

You can't, why would you want to?

You're welcome.

Not sure, I thought this would be a good way to test. I'm quite slow writing stuff out when I'm not used to programs. I've used your GUI since I delved into video encoding and never needed to go into the code

I put this back here, it was a PM.

hello. I am a bad tester sorry. Not done much of this before and was not aware how linux works or even terms like dependencies. 

They are not all there. the program launches. I think a big issue I am running into at the moment is framecounter. Its probably making it harder for you I'm running nobara as I can't get jack992's his fedora version to launch. Only just noticed he had one. 

Here is the report. I thought it was quite normal for things to be missing and user just installs them manually.

According to the start-up output there is no issue,
What issue do you have with FrameCounter? The output on start-up does not show any issues.
Do you see any errors?
Did you try the dev version of the AppImage?
AppImage files need to be set as executable and you usually need to have fuse installed. Read: https://github.com/AppImage/AppImageKit/wiki/FUSE

Selur, the reason I thought framecounter is the issue is line 363 framecounter, checksingle: false. it seemed like the only critical thing left. I had same false flags before, then I would install program and they go away. I have tried all builds. Can get ffmpeg to run in program with yadif but not QTGMC. I can't get QTGMC in terminal either, I will cross reference the errors and try to determine which one is further along.

"AppImage files need to be set as executable and you usually need to have fuse installed. Read: https://github.com/AppImage/AppImageKit/wiki/FUSE"

they are executable, sure I remember installing fuse, will check. 



Check version for FrameCounter, path: ./FrameCounter, checkSingle: false
