Thanks. Is it supposed to work (undocumented) in 0.19 or will it be in 0.20 ?

Doesn't work for me with PNG in 0.19 ... "frame%06d.ppm" is one file ? And what the "%" is supposed to mean ? Please release 0.20 soon and document the features and syntax ;-)

ffmpeg2theora -f image2 *.png -o output.ogg -> Failure

Is / will be PNG (and BMP) supported or only PPM ?

Bugs not fixed in 0.20, now 0.21 is out, will retest DOS386 21:56, 28 May 2008 (PDT)

Lossless compression for Theora II ?

Could theora II also have lossless compression integrated.

For many people it is important, especially people who take their movies seriously. or when it matters to have no data loss. Xpete

You had asked this on Talk:Main_Page already. We now have:
  • HuffYUV (free, but GPL'ed, no OGG support)
  • Lagarith (free, but GPL'ed, no OGG support)
  • Dirac lostless mode (BSD-like free, but not yet ready)
IMHO no need for Theora lostless. I suggest suspending this issue for a month or 2, then, when Theora 1.0 is out and Dirac is more mature, choose a preferred OGG lostless video codec ;-) DOS386 21:52, 28 May 2008 (PDT)

Are these features okay for theora or not?

Thank you for the open source codex theora with tools. However there is no variable framerate support. [1]

Is there double buffering in the theora decoder?

On blendernation there was an article where there was talked about double buffering added in a theora decoder, or something like that. (I'm not sure and haven't found the article on blendernation.)

This was part of adding a video texture player in Blender: [2]

When searching with google, there is no mentioning of double buffering in the theora decoder.

Wat is interesting to read, with integrating double buffering in the blender video project. The cpu consumption was a lot lower.
