issues with ffmpeg and arch linux

[ConnorRigby]

It looks like Arch linux has a new version of ffmpeg that is incompatible with qcma. Heres a snippit:

[codestation]

Are you building from AUR? i put a patch there to deal with that error

https://aur.archlinux.org/cgit/aur.git/tree/qcma-avdecoder.patch?h=qcma

I haven't pushed to the repo yet since i didn't have time to test if it break on older ffmpeg versions.

Ah i haven't tried from the aur. Will report back.

Just installed via the AUR and it worked great! thanks!
