I just got into usenet and some of the files downloaded are ISOs. I’m trying to figure out the best way to convert them to mp4s so that I can play them through plex. I’m running on a headless arch server (Manjaro), and I’d prefer to keep the conversion there if possible.
If there is no encryption involved, you should be able to unpack them with 7zip without any mounting and then convert with ffmpeg to a format of your liking. IIRC, DVDs usually consist of a bunch of VOB files. You can just cat them all together and then send directly to ffmpeg.
