I got a new drive and I can copy files fine with simple cp
on the drive. However for some weird reason I get Permission denied
with ffmpeg.
Permissions seem fine unless I'm missing something
> ll /media/manos/6TB/
drwxrwxrwx 13 manos 4096 Apr 16 00:56 ./
drwxr-x---+ 6 manos 4096 Apr 16 00:49 ..
-rwxrwxrwx 1 manos 250900209 Apr 15 17:28 test.mp4*
..
But ffmpeg keeps complaing
> ffmpeg -i test.mp4 test.mov

test.mp4: Permission denied
Simply copying like below works fine..
> cp test.mp4 test.mp4.bak
'test.mp4' -> 'test.mp4.bak'
Any ideas on what is going on? This is pretty annoying. Note ffmpeg is installed at /snap/bin/ffmpeg

So after a lot of digging I figured the issue is with snap package manager. Apparently by default, snap can't access the media directory so we need to manually fix this.
Check if ffmpeg has access to
removable-media
like belowAdd that permission if it's missing
