similar to: VP3/QT: 3.2.6.1 is OK w/QT6

The new 3.2.6.1 codecs work great with QuickTime 6 (thank you!), but there's no way for an application to identify them. And since the older 3.2.1.x and 3.2.2.x installers will actually *downgrade* the installed version of VP3, it would be nice if an application could warn the user. The attached patch increments kdxlqt_CodecVersion (and documents all the Component Manager arcana involved).

It looks like there's more QT 6 trouble, and this is specific to the post-3.2.5.x builds. I'm on it, and will try to sort things out by Monday. Cheers, Eric (not a happy camper!) --- From a note I sent to Dan Miller: The "3.2.2.0" binaries on www.vp3.com fail with an error I haven't seen before--"You may experience problems playing a video track in credits_v.mov

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

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 all, It's been a few years since I encoded a number of movies using the VP3 codec (v3.2) on my Quicksilver PPC. Now I have a new Intel mac and I'd like to play them. However, it seems that the codec offered on On2's website is only for the PPC architecture. Does anyone know a workaround or some other codec that works on the MacIntel platform? I'm using Quicktime Pro 7.

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

I was working with the VP3 code, planning to integrate it with Ogg for a self-contained solution for video playback, platform independant, no installation required, no QT, no AVI runtimes. My main interest is CD-based work using local files and portability/performance, not really into streaming or anything fancy (network error correction, prediction,

a couple points before I look at this too hard: "For VP3, since you can't do a constant quality encode" what? that should not be the case. Could be a QT-specific bug. Theora at any rate is certainly capable of doing constant-quality encode. This probably explains your standard deviation complaint -- VP3 is running a rate control alg, where the other codecs are just shooting for

I think I'll start with the simple stuff, just to be safe. :-) Here are some cvsignore updates, and a fix for the inter-project dependencies in the MSVC *.dsw file.

First, an introduction: I work in a group that makes educational software. In the coming months, we're planning to release our entire Mac/Windows runtime under the GPL. We currently encode our audio with MP3 and our video with VP3. For playback, we rely on QuickTime 5 on MacOS and Windows. In the short run, we'd like to help maintain the VP3 QuickTime codecs, preferably without

Taking a look ahead at your QT (OSX version) work, you have Theora Encoding and Decoding on the list. This could be very beneficial as many times the only way to get a constant frame-rate out of QT is to export (and for DV video recorded in QT, this can be a large issue). Another major issue is that the video coming from DV (at least the sources I have used) is almost always

Supposedly On2 transferred their Video Recorder and TrueCast5 streaming server into opensource along with VP3. Theora is obviously the VP3 project, and while I can find nothing on Xiph about it, the recorder source is offered on vp3.com; but I can find nothing on Xiph or vp3.com about what happened to Truecast5. I contacted On2 about whether TrueCast5 was really going to be open source, and they

Hi, Since a number of people are eager to try out the native VP3 decoder in xine, I have made a patch available, bz2-compressed: http://www.pcisys.net/~melanson/codecs/xine-vp3-decoder-patch.bz2 To work with this patch: 1) Get the latest xine-lib from CVS. Visit this page for more details: http://sourceforge.net/cvs/?group_id=9655 The module name is xine-lib, but you will also need

I don't know how to change a video quality on the fly - I want to provide a slider with a preview window, so user could see the result immediately in this window.

Hi, I have been on a documentation kick recently. I finally updated my VP3 format document tonight: http://www.pcisys.net/~melanson/codecs/vp3-format.txt v0.2: October 9, 2003 - expanded section "Reversing the DC Prediction" - added Appendix B: Theora Differences Feel free to look it over and point out any glaring mistakes.

Hi, Some of you may recall that I got the VP3 decoder working with the xine multimedia player some time ago and posted a patch for anyone else to try. I really messed up when I did that since I generated the patch against some random CVS snapshot of xine-lib. I did better this time and generated the patch against the latest release of xine-lib (1.0-beta4, released today). If you

Hi, A few questions: Is libtheora strictly backward compatible with VP3? Can I set it up to shove raw VP3 data through and trust it to decode the same way as On2's open source code did, loop filters and all? Also, is libtheora just supposed to be a C-based reference implementation? I was looking through the code and noticed a distinct lack of any kind of optimizations. Naive tree-based
