25 August 08 - 15:31MythTV 0.21-fixes with ffmpeg backport for Ubuntu Hardy
The latest weekly packages provided by mythbuntu enable you to use coreav's binary implementation of their x264 codecs. Theoretically this means that any HD file/show that is encoded x264 can be watched with less strain on your CPU. I tried it and did not encounter much difference between the native libraries and this 15$ proprietary one. But I stumbled upon a backport of the ffmpeg libraries from the development MythTV to the 0.21-fixes branch. I tried patching the source packages from mythbuntu with this new patch but got a build error due to the rather old x264 libraries provided with Ubuntu Hardy. But using this patch I was finally able to compile it. As soon as I collect some performance data and it turns out to be worth the time I will post a how-to.
Well, now I found out that this patch crashes while watching AVI files. No-Go for me. Then again I found this repository that has a synced ffmpeg version of the Ubuntu Hardy packages available.

05 August 08 - 16:46opengl bug with nvidia 8600 GT and MythTV
I had bought a new Nvidia 8600 GT card for my MythTV server/player. As this card is not supported to do chromakey for the OSD I wanted to get OpenGL to do the same trick. But I ran into the infamous black
screen bug which Mark fixed with his patches. After a steep learning curve I have finally written a tutorial to build your own Mythbuntu packages to fix the error. Aditionaly I had to remove "--enable-glx-procaddrarb" from the configuration as it keeps the error on 64bit systems. And don't forget to install the latest Nvidia drivers (177 or better).
