Hi, Is there a plan to make a FLAC ACM codec? Then we could use FLAC together with an open source lossless video codec like Huffyuv (http://www.math.berkeley.edu/~benrg/huffyuv.html). Daniel

This seems interesting so I thought I'd put it out to see what you all think...

It isn't available for now: format not frozen, no support in MP/ME, in FFMPEG it doesn't work :-( I doubt that Theora-lossless would be doable/useful ... maybe OGG-HuffYUV could be a more interesting idea ?

Well, we're talking about an uncompressed format. OggMNG is already "FLAC for video". However, it doesn't do YUV (well, not without abusing the ICC chunk, anyway) or interlaced. BTW, there are already a number of general "raw" video formats in professional use; it&...

...lossless, and that means supporting interlace and the chroma sampling it's likely to be needed for. This is also interesting work in that, once we're done, we'll have a standard to use for a compressed lossless format.. a FLAC for video, for editing or archival purposes, similar to HuffYUV. I'm drafting OggYUV and OggRGB on the wiki right now, so everyone can be on the same page for what the result of this will look like. The questions we need to answer are which colorspaces are needed and which encoding methods are needed. -- The recognition of individual possibility,...

I've made attempts to contact the author of HuffYUV over the past week. He's not easy to track down, but his (windows) implementation is GPL'ed, and it shouldn't be difficult to rewrite his codec into a GNU/Linux library, and such a rewrite could be placed under a Xiph license (I doubt there's much code reuseability, anyways, th...

I know this probably transcends the scope of the current aims of Ogg video, but one thing I'd consider extremely useful is a lossless video compressor. There are a few of them out there (e.g. PICVideo's lossless wavelet codec) but I've found no free ones so far. The primary use would be for storage of video clips that would be too cumbersome to store as raw frames but still require

I think that's something completely different. Any specialised lossless compression, as opposed to raw data will have it's own special setup requirements. > I'm drafting OggYUV and OggRGB on the wiki right now, so everyone can be > on the > same page for what the result o...

Is the Vorbis ACM codec still being maintained? Then I encode an avi with Vorbis audio, the sound gets out of sync after a while no matter what I try. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the
