Review of Mpeg-4 & on2's vp3...
The site: http://www.techimo.com/articles/index.pl?photo=33&SID=12&tag=SNnb323 has a review & comparison of several mpeg-4 codecs, and they also include vp3. (Be warned, it's a very big web page, due to all of the image examples!) Not really all that informative, but I thought somebody might be interested in hearing about it. *** On2 VP3 3.2.5.0 Positive: extreme low bitrate

[PATCH] nouveau/video: make sure that firmware is present when checking caps
Apparently some players are ill-prepared for us claiming that a decoder exists only to have creating it fail, and express this poor preparation with crashes (e.g. flash). Check that firmware is there to increase the chances of there being a high correlation between reported capabilities and ability to create a decoder.

Fwd: Re: [Olpc-open] XO review & Theora
As far as video playback is concerned, it seems to mostly come down to how the video is compressed - although Gnash (the open flash player) still has a ways to go to play flash media as well as the closed source flash players. For the Colingo activity and library, we've found it very difficult to find optimum settings for flash and instead have decided to go with Theora. We've managed to

Re: DSP stamp
Yes, the Theora codec is based on VP3, which is an earlier version of ON2's VP6 codec. Theora is currently at its alpha 3 release, and is stable enough to have been used already for streaming live video from a number of conferences, and for encoding several videos that can be found at www.theora.org. Development has progressed to the point that the value of the codec can be seen. That

video codec comparisons
Reviewers who have published comparisons of video codecs recently tend not to publish their source video clip, nor encoded video clips.? It might help promote theora if there was a link we could provide to a nice source clip, only one or two minutes long with a mix of action and talking head spots, with several versions of it compressed in theora format; maybe 250 kbps, 500 kbps, 750 kbps, 1 mbps,

Dynamic Change Parameters..
I am going to improve theora codec with dynamically changing way. In this case we want to change compression parameters like video_q, sharpness when a keyframe is generated. When i set video quality parameter using cpi-> pb.info.quality in CommpressKeyFrame in encoder_toplevel it will not change dynamically. Can you please help me to do this.

Ogg doesn't measure up?!
Nullsoft Streaming Video. Basically a video container format. Can be used for files or streaming. Though it can use any audio video formats internally currently it is just VP3/MP3 (or VP5/MP3, but that's internal only and not publicly available). Basically video for the next version of SHOUTcast. http://www.nullsoft.com/nsv/ From: "Geoff Shang" <gshang@uq.net.au> > BTW,

Slowdown on lots of motion
I'm playing the "Honey" movie (both Honey-small and Honey-large) and I notice significant slowdown during periods of lots of motion (when the camera shakes, when the first man hops into bed, when people turn around and approach the camera, etc.). The audio plays smoothly all the time but when there is a lot of motion, the picture freezes and resumes when there's less motion.

Limiting bandwidth to around max. 8k per second - possible? Working?
Hello, I am using the latest binary download from vp32.com, just as a starter. We try using the VP32 codec in a video conferencing application, replacing Intel indeo for obvious reasons. I must note that I have considered contacting ON2 for a license of the VP5 codec, but after sending emails for amore than a week and never getting back calls after they were announced, and after not reaching

Hi, just a note for everybody who stumble across this thread in the future in order to bring this thread to a proper end. If I run the kernel with nouveau.debug="PVP=debug,PBSP=debug,PPPP=debug" I see messages about the firmware files gettings loaded. If the firmware files are missing, I get some warnings/errors. So far everything works as expected. But if I invoke

Limiting bandwidth to around max. 8k per second - possible? UPDATE
Ok, we got it working with 176x144 resolution. The following string produced an image that was not falling behind too much for too long - basically a little when it was getting TONS of movement, and then catching up fast. "65 58 110 0 1 1 90 8 120 1 1 " Now, we need to get this working on a 320x240 resolution, too (as sadly VP3 does not support 160x120. Seems to be a little senseless,
