Your NVIDIA GeForce 7600 GS is an NV40 series card and has a VPE2 video decoding engine. According to the VPE2 details in the Nouveau Wiki at http://nouveau.freedesktop.org/wiki/VideoAcceleration/
* MPEG4 and H.264 decoding is not possible via VDPAU. * MPEG1/2 decoding is possible via VDPAU but is not implemented yet. * Only MPEG1/2 decoding is possible via XvMC, but you will need a Kernel 3.11 and mesa-git. The good news is that you don't need any firmware. * To use XvMC, you need to point your /etc/X11/XvMCConfig at the libXvMCnouveau.so library (single line with the full path). The under-development Ubuntu 13.10 currently has the 3.11.0-2.5 kernel, which is based on the upstream 3.11-rc5 kernel. If it doesn't already have a new enough version of mesa it probably will by the time of it's final release in October 2013. If you want to install the 3.11 kernel on an earlier Ubuntu release, you can get it in a PPA from http://kernel.ubuntu.com/~kernel-ppa/mainline/ and instructions on how to install an uninstall it are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds You can install the latest mesa on an pre-13.10 versions of Ubuntu by using the xorg-edgers PPA at https://launchpad.net/~xorg- edgers/+archive/ppa So it looks like your original MPEG4 use case is not possible via GPU hardware acceleration, although I'm not sure why xv-blit is not producing any images for you. It's probably worth re-testing on a more recent version of Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/515865 Title: "Wrong" Fallback Video Renderer playing MPEG4(NUV) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mythtv/+bug/515865/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
