Is ffmpeg necessary for playing back local files? #98

Opening this to continue discussion we've been having by e-mail. Does ffmpeg need to be installed for TiLiA to playback local files?

FelipeDefensor commented 4 months ago

@azfoo Let's continue talking here.

You mentioned that you are unable to load any audio on a clean install of TiLiA. I think I have reproduced that behavior with ffmpeg installed. Following a hunch about what's going on, I was able to fix it by running TiLiA with admin privileges. Does that fix it on your end?

It would be very weird that ffmpeg is both required for playback and not bundled with PyQt because I have succesfully loaded media in previous versions of TiLiA in several different computers and some of them definitely didn't have ffmpeg available.

So I tested things again and it seems that PyQt6.6 doesn't have the issue, but 6.7 has. Considering 6.7 was only released in April, that might explain your previous experience. Perhaps downgrading and defining PyQt's version would be a quick fix?

Having to run an app like that with admin privileges makes the app sound suspicious...

Yeah, I agree that requesting admin privileges is not ideal. Downgrading seems great, but I wasn't able to do it on my computer as some DLL error crops up. I'll try again.

Try: pip install --force-reinstall PyQt6==6.6.0 PyQt6-Qt6==6.6.0 PyQt6-sip==13.6.0 PyQt6-WebEngine==6.6.0 PyQt6-WebEngine-Qt6==6.6.0?

Will try, but I'm away from my setup until Monday.

Installing all dependencies with pip install -e . and then downgrading PyQt with the above works on a fresh environment on Windows 11. I will retry this on my usual setup tomorrow, but I think we can be confident that this works.

Confirming that this also works on my usual setup.

I'm closing this one as this douments the PyQt version issue. The question about bundling ffmpeg separately remains, though.
