similar to: Formats other than Vorbis in Ogg

I sent a little mail some time ago asking if there was going to be an ogg pic-format, and you replied that PNG, MNG and JNG is good enough (sorry for this late answer btw).. But, consider this: The ogg video-format (tarkin ? where do you get these names from anyway ? :) ) needs a way to compress its frames. Are you going to use MNG for that ? :) .. If you had an ogg pic format, that format could

With both vorbis and libmng nearing stable status, I've been thinking about combining the two to make a real multimedia format. What would be involved in embedding mng in an ogg bitstream? From what I've read of the documentation, there doesn't seem to be any codec-enumeration system. Do we just interleave the packets and let the player guess based on the headers which codec to try? I

I am trying to figure out file(1) magic(1) for Ogg and Vorbis. (I am using file from NetBSD 1.5.1.) Currently I have: 0 string OggS Ogg data >29 string vorbis \b, Vorbis audio Some results: $ file ~/audio/kaas.* /home/reed/audio/kaas.mp3: MP3, 128 kBits, 44.1 kHz, Stereo /home/reed/audio/kaas.ogg: Ogg data, Vorbis audio /home/reed/audio/kaas.wav: RIFF (little-endian) data, WAVE audio,

I'll get to the technical aspects of these letters in a bit; they require an a little thought and I'm knee deep in the codebook engine right now... > <RANT> > > I personally favor the MNG approach over the Ogg strategy because of the way > the licensing agreements read.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi Is there any tool out there wich allows you to use a flac file with ogg metadata as an the file of origin and converts its to an ogg.vorbis file without losing any of the metadata tag, I know there is a perl script wich does something similar but it keeps the metadata in separate files, basicly what I am asking is if there is any application that

Have you considered trying to have FLAC become an official part of the Ogg project? Ogg has Vorbis but no lossless codec, and FLAC is already production quality. You've already written the code to wrap FLAC in an Ogg bitstream. Ogg Squish seems to be abandoned, and it would be a grand waste of effort to revive it when FLAC already works so well. The Ogg people would be much better off

I just read some of the discussion on the list about 'bitrate peeling' and remembered an interview of Monty that I have read recently. In it he says that Vorbis uses MCDTs <sp> and that these are theoretically reversable. And now, I learn that theoretically we can use bitrate peeling to make smaller files from larger ones, and that leads to my question. Could I theoretically

This is a proposal for Ogg MIDI streams. It will also help other stream additions to Vorbis, as they should follow a similar model. Ralph has done much of the work on this, and also is working on MNG Ogg streams. Background ---------- I was contracted to do this work, so even if you can't think of a use for this, there is one ;) Basically with midi in Ogg, we can have a synchronized

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

Hi everybody, I wrote last time some code to do video compression using a 3d integer wavelet transform. Since it uses a reversible lifting scheme and avoids a lot of floating point operations compared to Jacks initial Tarkin code, this should be somewhat faster and allow lossy+lossless compression. The current implementation is very experimental, but nevertheless I would be happy if some of you

Dear David, I hope it's ok to forward your email to the developer lists. I have not seen a comprehensive scheme for MIME type naming and file extensions for ogg files yet - please anybody put me in the picture if there is. However, I have seen application/x-ogg used for ogg-vorbis files, which is according to MIME type registration rules an unregistered and experimental MIME type (see

I thought some here may find this interesting... There has been discussion in Monkey's Audio forum about creating a new open source format for lossless audio compression with the intent of creating a *standard* for lossless compression, similar to what Xiph is trying to do with Ogg Vorbis. Some have even been tossing around the idea of trying to work in conjunction with Xiph on this, and a

Hi, I think we can start by defining an official field name at www.xiph.org/vorbis/doc/v-comment.html which is used as a file system link to an existing image file. I suggest the field name to be "PICTURE". What is ogg MNG? Is it a container format for PNG files which should be embedded in OGG files? If I understand correctly, the picture would be placed in a different logical stream

[ I'm not in the list because I didn't find a digested version; please move the lists to sourceforge.net, and we would have the digested version. I read the replies from the archive. ] Hello. Would it be possible to allow Vorbis use the same codebook for multiple files? I could keep a 650 MB codebook on CD-R and use that for all my audiofiles. If that is possible, how much the

Hello, I have proposed to WebM to use FLAC in a future version. Since FLAC was designed a decade ago, I was wondering if there were any new compression techniques that FLAC could use in a new version to improve compression ratios. If so, it would be worth synchronising with WebM for compatibility reasons. Here's the WebM discussion:

I agree, but the idea behind the OGG formats is to build patent free codecs. Is FLAC really patent-free ? And does the OGG team agree to include FLAC in their specs ? smoerk wrote: > I agree.
