Unrelated, but in one of the versions of ffmpeg (2.5 I think), I screwed up something major and only files worked. No networking or special URI schemes.
What Jurassicc needed was a version that works with the concat: protocol.
The reason concat: or data: doesn't work in 3.0.2 is because of a different type of amiga-paths patch I used. Basically, if no :// is present in the full path name, then it's treated as a file path, and so concat: and data: will look for volumes with those names instead of being treated as protocols. If you actually have volumes with those names, in the upcoming version (and previous fully-working versions) you just need to insert a capital letter (i.e Data: instead of data:) and it'll treat it as a file path again. I don't want to break or remove any functionality.
A newer & fixed version will go up soonish (probably within a week).
concat can be used in 3.0.2 if you use a list file and -f concat. Check
https://trac.ffmpeg.org/wiki/ConcatenateSince 2.8.7, you need to also use -safe 0 before -i if your concat paths are absolute (i.e contain the volume name).
Edit: A new build of 3.1.1 is available for testing using a different style of paths patch. PM me for a link.
