Hello. As a note, dvdread if compiled using mingw or cross compiled for windows, seems to fail with all sorts of failure messages. This patch (from the vlc team [1], thanks!) seems necessary there: https://raw.github.com/rdp/ffmpeg-windows-build-helpers/master/patches/dvdre... I'm not sure if it affects other OS's or not. I "think" the problem stems from gcc packing structures differently with 4.7+ though I'm not certain [2] . All I really know is that, for windows with gcc 4.8, it fails without this patch and works with it. Thank you, thought I'd mention it since there was a recent call for trivial patches. -roger- [1] https://github.com/videolan/vlc/blob/master/contrib/src/dvdread/rules.mak#L3... and https://github.com/videolan/vlc/blob/master/contrib/src/dvdread/dvdread-win3...
