[vlc-devel] Theora in configure.ac

[ogg.k.ogg.k at googlemail.com]

The weird stride problem happens also (on some videos) for
the 'filename on top of video' string. A clue might also be that
the video comes in at 4:3 ratio, though the libtheora plugin
makes it come at 16:9 ratio, it that rings a bell for anyone.

Also, the ffmpeg not playing nice with Thusnelda videos bug
I was remembering was fixed in december, it seems.
