[FFmpeg-devel] [PATCH] urlconcat protocol

[Michele Orrù]

Ok, tested with some videos, splitted previously with "split" , using
ffmpeg, ffplay, and also seek_test (just cat:$file).
Seems to work.


About *urinod : Why waste time destroying and making a new pointer?

It's just for urls (also http, ftp, etc.) , but if you concat two videos of
different screen size,  for example, it won't work.

Me, too, I prefer urlconcat, and since the user will only use cat:, it
doesn't really matter if it's a little longer.

I repeat: I've tested it only with some splitted videos. Trying, for
example, to concat foo.avi|foo.avi, you may would see in the output just the
first video, since its time, title, ... are written in the first file (2/3
times it won't work, tested :D).
