Hallo all, I currently hacking on cheese an got problem with variable framerate produced by webcams (2-30fps). There is no problem to encode it with theora, but problem to mux it in ogg. Or at least to play produced file. There is no problem tu mux it in to matroska. My question is: should actually ogg support timestamps, also variable framerate? If yes: it seems to be som...

Hi, This is probably a slightly odd question.... Is there anyway to decrease packetization? I'm using voip over a wireless network, and framerate is extremely important! Is it possible to reduce the framerate? Right now it's using about 90 frames/sec in to the phone and 40 frames/sec out from the phone (back to the PBX)

..., very nice. The effects are very tasteful and enhance the desktop experience instead of being distracting. Compiz itself works great, the animations are smooth and it's very nice that it now uses the Metacity themes. The only reason I'm not using Compiz full time is that it clobbers the framerates of my other 3D apps, aka games. From what I understand, one way around this would be to activate the unredirect_fullscreen_windows option which would disable Compiz effects for fullscreen apps and hopefully restore the framerate of the games. Of course, that doesn't work. From what I rea...

I've been getting max 10 FPS in Oblivion, even with extremely low graphics settings. Any ideas why? I didn't have any problems with running Oblivion on Windows, and even for Wine this seems quite low. I think it might be my graphics card drivers possibly. OS: Ubuntu 9.10 Karmic GPU: nVidia 8600M GT CPU: Intel Core 2 Duo @ 2 GHz GPU Driver: Version 195 (I got it by going System ->

I'd like to get basic information about a Theora file using C# .NET. How can I get started on this? I know there's oggz-info and other utilities, but I'd like to do this straight from in .NET. What's the documentation page to find more on this? Can I just read the first x bytes of the video corresponding to each field? I found this page which I think is what I need, but I'm

I tried to encode some video from a DVD with encoder_example and ffmpeg2theora, and it looked great, except that with both encoders the A/V sync would drift noticeably after about 10 minutes, and by the end of a two hour movie it would be a couple seconds off. So instead of just whining about this and waiting for someone else to fix it, I decided to try to learn about what's causing the

Greetings to everyone. I understand that this problem may discussed many times, and i searched through forums but nothing solved my problem. In windows game runs perfectly with max details at 1680x1050. And i have something about ~50 FPS. But in Linux with same options i have ~18. I don't know why is that, when i'm trying to use native dll's in Wine config game won't startup. I

I have a strange problem in Halo where the mouse seem to run many times slower than the framerate. Even when the framerate is decent the mouse is choppy for lack of a better word. It's sort of a strange motion I can't really describe, sticky and halting, but it does seem to be related to the framerate in that that faster it is,the faster the mouse is. I have heard of a mouse warping...

http://www.youtube.com/watch?v=BcwieeBEySc My performance doesn't even come close to this even at low resolution and overclocked, and I have the 512Mb version of this card, this guy has the 256mb version and I have the same settings, i've seen people run some really high-end games on this like crysis at decent settings, (not high just decent). Does wine actually bottleneck performance on

Hello, I'm using ffmpeg2theora.linux to encode video casts from http://digit.cz For one particular episode 24, I discovered two issues: 1. minor one - at beginnig, software is reporting very big and long result ffmpeg2theora.linux digit24.mp4 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'digit24.mp4': Duration: 00:42:41.04, start: 0.000000, bitrate: 1177 kb/s Stream #0.0(eng):

Hi I'm trying to store video I encode to a file using Theora and Ogg. The video I record is from my webcam and although the framerate is set to 30 fps I rarely get more then 28-29 fps. Since Theora is fed with a framerate which isn't precise the time of each frame when I play it in VLC doesn't match the exact time of when the frame occurred. So basically I wonder how can I sync a video frame to a clock using Theora and...

Hallo all, I started this discussion today on gstreamer.irc and ogg-dev list. So there seems to be different results.

We build a Voip client with Iaxclient(Jiaxclient+Iaxclient2.1beta1+Theora1.0+libvidcap0.21),when we established video call with resolution 640X480(bitrate:500000,frameRate:11,fragsize:1472) in both sides,the CPU is consumed about 100%,the workload of Asterisk server is good at that moment.This issue does not exist with the resolution 320X240(bitrate:204800,frameRate:11,fragsize:1500), the environment is as following, - CPU Interl Celeron 2.66GHz,RAM1GB,...

Hi, I'm a newbie here, so please don't threat me too bad. :D I wanted to ask you .. Yesterday I installed Linux Ubuntu 8.04 (Hardy) on my PC, it's the first Linux OS I use on it and I'm pretty confused, but I'm trying to make it work anyway. I installed WoW, using this FAQ https://help.ubuntu.com/community/WorldofWarcraft. I followed it, step to step, except for the

...the plots to a multipage pdf, it is relatively trivial to then use the pdf2swf command in SWFTools (http://www.swftools.org/download.html; mac install instructions here: http://9mmedia.com/blog/?p=7). pdf2swf seems to generate swf animations with a slow frame rate, but you can increase the framerate using 'swfcombine -r 30 --dummy myslow.swf -o myfast.swf', where the value passed to -r is the framerate. Unfortunately, this method seems to have limitations with regards to the number of plots it can convert. For example, on my system (17" macbook pro, 2.33GHz, 2GB ram, O...

...Far-End SES" on their side) Since the circuit appeared to work fine, calls went through, and the crc counters on our side was zero, it was impossible we were getting that many errors and something must have been wrong with our handling of the E-bit signal. I've come across the DS21554 framer documentation and i've seen that it has a flag for enabling the E-bit generation in the "TCR2" register and that the wct1xxp.c wasn't setting it. So i tried this small patch and the telco is perfectly happy with it, now, the E-bit error has disappeared. Since there had been...

Hi, I've been thinking about how a Theora encoder could be integrated into mencoder or transcode and I'm not sure whether I understand the A/V sync strategy of Theora/Vorbis correctly. When transcoding from some video format (ie MPEG2 or DivX), at least some images of the video stream will have time stamps, as well as the fragments of the audio stream. Or at least time stamps can be
