My concern is primarly the 'marketing' aspect. If UCI, or MCF, or any other interface, is adopted by the toolmakers, then that's a perfectly good solution. <p>-----Original Message----- From: Christian HJ Wiesner [mailto:christian.hj.wiesner@web.de] Sent: Tue 11/12/2002 10:10 AM To: theora-dev@xiph.org Cc: Subject: [theora-dev] Re: [vorbis-dev] ACM codec

All the notes you mention for VC are in vp32_build.html in the release, but thanks for reiterating. Last time I built for Mac I believe I did the os9 version in CW6 and the OsX version in CW8, but I can't think why they shouldn't both compile in CW8. <p>-----Original Message----- From: Tabuleiro [mailto:beta@tabuleiro.com] Sent: Thu 9/5/2002 4:25 PM To: theora-dev@xiph.org Cc:

some of you may find this helpful: I've uploaded a short (5 second) raw clip in yuv4mpeg format, associated audio, and batch files to exercise the encoder & decoder examples. In addition I've included the file as compressed (test.ogg), and a longer version as well to test playback sync. Notes: to use MPlayer with the -vo yuv4mpeg option, you need to get the latest release and compile

A new mailing list has been created -- theora-codecs@xiph.org. This list should be where we discuss issues pertaining to Qucktime and Windows codec implementations, including legacy VP3 codecs for those platforms. We've done this to keep the discussions discrete and focused. There is a pressing need to maintain the existing VP3 codecs until we get Theora up and running. Anyone who is

QuickTime 6 for Windows breaks the VP3 codec quite severely--if you turn on "Safe Mode" (which forces QuickTime to draw through GDI), you'll see a white or black screen instead of video. This is logged as bug #2111990 in Apple's QuickTime feedback system. The fix is a classic one-liner, although it took me a long time to figure it out. :-/ Also attached is a patch to bump the

hmm -- you make a good point. However note that Divx is quite popular in spite of having gone with AVI format, so your logic doesn't hold in that case. Frankly though I sort of agree, in that Divx would have been even more popular and cause less headaches with a .DVX extension rather than AVI. I 100% agree that the form of the codec that should be distributed for playback is OGG. The

At this point, my understanding is as follows. Monty has the final word but I believe this is his intention: * Theora is a video codec. It is a modification of VP3. Presently it is assumed that Theora will be a superset of VP3; ie, VP3 streams can, with a little header magic, be losslessly transcoded into Theora streams. However, we expect future versions of Theora to diverge significantly

Hi everybody, I'm currently writing a real time video conferencing tool for Windows and I want to use the Theora Library for this purpose. My questions are: 1.) is there a vfw implementation of theora 2.) if no, can I bundle the VP3 vfw codec that's available from On2's website with my application Best regards, Florian (Stuttgart, Germany)

As I understand it the current plan is to make it possible to losslessly transcode VP3 video to Theora video. In my experience, one of the "features" of VP3 is it drops frames in the event that there is little/no movement in a frame, or if "drop frames" is enabled, to drop frames if the data rate is getting too high. I understand that the way that VP3 does this in

Well, I've been slamming my head against this all night, so it's time to ask for help... Having gotten together a reasonably decent port of what I thought was the whole API to the Ogg Way, complete with Ogg mem management and bitpacking, I started digging deeper in the code... only to find that it looks like I only have a middle stream handler. The encode and decode code both assume that

[standard disclaimer about my mail format] in ftp.vp3.com/theora user: vp3 pass: vp3dev theora_dbm_5-28.zip this implements a bitstream change; the header now contains a compressed huffman tree rather than the frequency counts (as discussed) pardon my inability to use diff correctly. The change in toplevel.c is trivial (new function names & params) huffman.c is the important one. I

just for the record -- I think you mean video/theora when you mention vorbis+VP3. Vp3 is becoming Theora. Tarkin is another video codec project at Xiph. As for this whole MIME type issue, can someone enlighten me as to how this problem is addressed with Quicktime, Microsoft, and RealNetworks plug-ins today? Also, does an MPEG4 tag specify which audio codec is used? thanks - dan

I found out about vp3 from the new winamp and coincidentally i also happen to be trying to find a suitable solution to broadband streaming. I have used flaskmpeg to create a 17mb .avi file from an 82mb Mpeg 1 file and it looks great it took about twenty minutes to encode. It runs for eight minutes and the audio is also fantastic using the lame encoder. However when I try to do the same in

Hi, Can anyone tell me the significant differences between VP30 and VP31 (or are you allowed to)? Are there different token and quantizer tables? Are there algorithmic differences? I have a VP30-encoded file that plays with the VP3 VfW DLL but not with the open source decoder. Thanks... -- -Mike Melanson --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project
