However, there are thumbnail solutions that work, like the Ogg Video Tools http://www.streamnik.de/oggvideotools.html.

https://bugzilla.wikimedia.org/show_bug.cgi?id=47465 --- Comment #6 from Jan Gerber jger...@wikimedia.org --- One way to improve this would be to force more keyframes. currently TMH has a hard limit of how fare back it looks for the previous keyfr ame. Another option would be to switch Open Access Media Importer from Ogg (Theora/Vorbis) to WebM (VP8/Vorbis) -- You are receiving this mail because: You are the assignee for the bug.

https://bugzilla.wikimedia.org/show_bug.cgi?id=47465 --- Comment #7 from nils+bugzilla.wikimedia@dieweltistgarnichtso.net --- Looking at the code, it already tries to use OggThumb. As I OggThumb does not produces garbage thumbnails, why not just install it? https://git.wikimedia.org/blob/mediawiki%2Fextensions%2FTimedMediaHandler.git/83fc3186a3aabce5406814c29294f6bc2d90ca54/TimedMediaThumbnail.php -- You are receiving this mail because: You are the assignee for the bug.

https://bugzilla.wikimedia.org/show_bug.cgi?id=47465 --- Comment #9 from Jan Gerber jger...@wikimedia.org --- OggThumb is no longer used since videos are accessed via http to extract frames and OggThumb does not support that. Above patch calculates the seek offset based on framerate and fixes thumbnails for the videos linked above. -- You are receiving this mail because: You are the assignee for the bug.

https://bugzilla.wikimedia.org/show_bug.cgi?id=47465 --- Comment #4 from Jan Gerber jger...@wikimedia.org --- This is a limitation/bug of libav/ffmpeg regarding ogg theora videos with large gaps between keyframes. We might be able to tune this but some videos will fail unless libav/ffmpeg is fixed to decode from the previous keyframe. -- You are receiving this mail because: You are the assignee for the bug.

After downloading two media files, one with a normal thumbnail and one with a corrupted one, I have the same problem on my local computer (for the corrupted one, totem-video-thumbnailer does not create a thumbnail at all). Is there a reason to assume that the software on the servers is faulty, instead of the video file? -- You are receiving this mail because: You are the assignee for the bug.
