For many years im using the ubuntu with nouveau and the yuy2 scalemode in mame. I think the last one was 11.10 or 12.04, not sure. Now in the ubuntu 13.10 the yuy2 scalemode dont work in mame, but works fine with the intel driver. Tested with the kernels 3.11 and 3.12 from the ubuntu repository. I think there's a regression in the nouveau used in ubunt...

Hi everyone, I face a problem trying to encode a mkv file into theora using directshow filters I have a mkv file containing only video encoded in YUY2. I use the DirectShowNet Lib V2.1 ( <http://sourceforge.net/projects/directshownet/files/> http://sourceforge.net/projects/directshownet/files/) I use the matroska splitter directshow filter v1.0.2.9 ( <http://www.matroska.org/downloads/windows.html> http://www.matroska.org/...

Hello, I am trying to get the latest wine (Wine 20030219, fake windows) working with the GordianKnot (0.27). Unfortunately, Virtual Dub is not be able to compress a avs-file with the DivX-codec. It crashes if trying to. Also, it would be nice to compress an mpeg-source with Xvid but also it crashes. BTW, VirtualDub does not list it in its codecs window ?f "msvfw32" is set to

...ent giving a high-level overview of how to use "libtheora"? As it stands, I'm scrounging through headers and example code, and doing a whole lot of guessing. In the meantime, could you either confirm or deny the following guesses? 1) Before compressing with Theora, I must unpack my YUY2 data into three separate arrays (Y, U, and V respectively), and record in a "yuv_buffer" structure. 2) "yuv_buffer.y_stride" is this the number of bytes in one row of Y data. In other words, y_stride*8/y_width = num bits per Y component 3) "theora_encode_header" mus...

...h display DivX 4.01 material with sound. This is simply great :-) However, the performance is not that great. Especially when going fullscreen the cpu is overburdened (slide show). I assume that the XVideo extension is not used yet? xdpyinfo says I have the XVideo extension and xvinfo says I have YUY2, YV12, UYVY an dI420 image formats. Is support for the XVideo extension being worked on or is it already included (and I did not enable it)? regards, Bernhard Ege

It should be able to say here's some YUY2 data and OggStream could figure out how to encode that to Theora by using an intermediate filter. >Um, other formats? I don't grok your statement.

...hat happens if i set it to 0 ? Will it do some default action ? Also the aspect ratio fields... i am just setting aspect_numerator = videoWidth aspect_denominator = videoHeight Am i correct in doing this ? Any restrictions ? Also... i'm noticing that most of the filters in directshow output YUY2 and not YUV12... just curious if there is code floating around somewhere to do the conversion before i write it myself... it doesn't look too complex anyway. Also, looking at some wmv output... (which is a format that outputs YV12)... it doesn't set a frame rate in the setup header... so i...

Has anyone noticed this? I have a video made with Final Cut Pro, which I convert to .mov via Compressor. This .mov file plays back fine in Quicktime. But when I then use ffmpeg2theora to convert to ogv, the video seems to play back too fast compared to the audio (I'm using VLC 1.0.2, the latest I believe, to play back the ogv file, and I also have an app that uses the recently
