Current versions of ffmpeg2theora include by default a metadata track as substream 0.0; the version of ffmpeg we have installed seems to barf on this and refuses to process the file: Error generating thumbnail Error creating thumbnail: [theora @ 0x7ffbd5f4f330]Theora bitstream version 30201 [theora @ 0x7ffbd5f4f330]584 bits left in packet 81 [theora @ 0x7ffbd5f4f330]7 bits left in packet 82 Input #0, ogg, from '/mnt/upload3/wikipedia/test/e/ed/PSA-Web-400-15fps-nl.ogg': Duration: 00:03:10.8, start: 0.533333, bitrate: 314 kb/s Stream #0.0: Video: 0x0000, 1000000.00 fps(r) Stream #0.1: Video: theora, yuv420p, 400x224, 15.00 fps(r) Stream #0.2: Audio: vorbis, 44010 Hz, mono, 64 kb/s PIX_FMT_YUV420P will be used as an intermediate format for rescaling Output #0, mjpeg, to '/mnt/upload3/wikipedia/test/thumb/e/ed/PSA-Web-400-15fps-nl.ogg/mid-PSA-Web-400-15fps-nl.ogg.jpg': Stream #0.0: Video: mjpeg, yuvj420p, 400x224, q=2-31, 200 kb/s, 15.00 fps(c) Stream mapping: Stream #0.0 -> #0.0 Unsupported codec (id=0) for input stream #0.0 Ideally there's some parameter we can pass to ffmpeg which will ignore the track if it's present; worst case we should identify a version of ffmeg which works and upgrade to it. A thread from December 2007 about this sort of issue: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-December/039774.html --no-skeleton option can be passed to ffmpeg2theora to avoid adding the track as a workaround.
*** Bug 16208 has been marked as a duplicate of this bug. ***
The current version of ffmpeg from RPMFusion (ffmpeg-0.4.9-0.52.20080908) seems to handle the Skeleton stream by ignoring it: Stream #0.0: Invalid Codec type -1 Stream #0.1: Video: theora, yuv420p, 512x288, 25.00 tb(r) Stream #0.2: Audio: vorbis, 32000 Hz, stereo, s16, 56 kb/s
Per mdale this is also breaking chopped Oggs, which add a skeleton metadata stream. :( Current image scalers *appear* to be using the stock Ubuntu 8.04 ffmpeg package: Version: 3:0.cvs20070307-5ubuntu7.1 I can't see a newer package in the official hardy-backports set, so we might need to find an unofficial package or update it ourselves or... bleah. Tim, can you take a look?
Backported the one from intrepid to hardy, it just needed a slight tweak to the build deps. Seems to work.
