Win 10x64
VLC ver. 3.0.10 Vetinari
I'm converting an MKV to MP4 (not sure if that matters) after its done it says "The output file already exists Overwrite / keep existing file" when finishing for the first time. This goes on forever no matter what option you choose. It just re encodes endlessly if you choose overwrite.
Tested on vlc-4.0.0-dev-win64-d77d82b4 also failed with a different issue:
Your input can't be opened
VLC is unable to open the MRL 'sout#transcode{scodec=none}std{access ... etc
