Comment #14 on issue 17174 by gmaxwell: Theora block-level quant not supported http://code.google.com/p/chromium/issues/detail?id=17174
Please also try: http://people.xiph.org/~tterribe/tmp/sign_irene_cif-3qi-b.ogg The first example is all I-frames, this video is more typical. You can also grab the ffmpeg2theora nighties. Unfortunately ffmpeg doesn't use the libtheora reference code and ffmpeg's support appears to have mostly been written against what was found in the wild rather than the Theora spec. The intersection of ffmpeg experts and theora experts is nearly, but not quite, the empty set. :( I'll go nag the person who did this fix. To the best knowledge of the Theora developers the current support in ffmpeg mainline works for all the files thrown at it except: It only handles 4:2:0 chroma subsampling (Theora also allows 4:2:2 and 4:4:4), and the offset parameter is not handled correctly (so you will get colored lines along the borders of some videos). FFMpeg's theora decoder is also substantially slower than the reference encoder, though it has gotten somewhat better recently. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
