Description Michael Dale 2009-08-26 13:30:31 UTC
The current version of ffmpeg used on wikimedia servers seems to mangle the thumbnail generation of videos encoded with the latest theora encoder. (included with firefogg) 

I have not confirmed but I believe a more recent version of ffmpeg solves this problem. An alternative would be to use a xiph based tool to abstract the thumbnail.

Reassigning to Fred for software update.
Comment 2 Daniel Schwen 2009-10-07 16:42:40 UTC
More test cases:

in the #theora channel I was told that old versions of ffmpeg do not fully implement the theora 1.0 standard, and that the 1.1 encoder uses unimplemented features.

Please update.
Comment 3 Michael Dale 2009-10-07 20:54:26 UTC
We added support for oggThumb for thumbnail generation r57439. This supports theora 1.1 encoder. The example files should work now.
