Re: [PD] alternative for quicktime

De: "Mathieu Bouchard" matju@artengine.ca

Though ideally, I'd be replacing it with gmerlin, a newer library by the same author. Last time I looked, something about installing it was a mess, but I don't remember what it was, and it was years ago, so it's surely much better now.

It's still a mess on windows, on msys apply this following patch for resolving missing X11 headers:

http://comments.gmane.org/gmane.comp.video.gmerlin.general/325

there are plenty of errors popping from *_ffmpeg.c, I've manually resolved some, but this is not really elegant.
