Post subject: | no working video renderer available (xvmc-blit) |
Hello, I have installed Knoppmyth 5.5 on a Via Epia Me6000 Mainboard and I need to use the onboard chipset CLE266 for video acceleration. I have also installed xserver packages of openchrome. In my xorg.conf I start the driver in section "Device" with "openchrome" This all works as I have a perfect working DVD-playback with Xine. Unfortunately my Mythfrontend does not use the hw acceleration although I have tried different selection in the tv output configuration. I have tried XvMC as well as Via-XvMC. As video renderer there is xvmc-blit available but when I start whatching TV/recording I receive messages like Quote: > VideoOutputXv: Desired video renderer 'xvmc-blit' not available.
> codec 'None' makes 'xv-blit,xshm,xlib,' available, using 'xv-blit' instead. But the fall back renderer obviously do not support hw acceleration. (High CPU load, choppy video) I did some research in the internet and I found that this might be an issue of the new in Mythtv version 0.21 (which I have installed) http://svn.mythtv.org/trac/ticket/4792
Please include all output in bug reports. MythTV Version : 17686M MythTV Branch : branches/release-0-21-fixes Library API : 0.21.20080304-1 Network Protocol : 40 Options compiled in: linux release using_oss using_alsa using_arts using_jack using_backend using_dbox2 using_directfb using_dvb using_firewire using_frontend using_hdhomerun using_iptv using_ivtv using_joystick_menu using_libfftw3 using_lirc using_opengl_vsync using_opengl_video using_v4l using_x11 using_xrandr using_xv using_xvmc using_xvmcw using_xvmc_vld using_bindings_perl using_bindings_python using_opengl using_ffmpeg_threads using_libavc_5_3 using_liv My (urgent) questions: - which renderer is the right one to pass video out through CLE266? When I tried any other renderer offered in the Mythtv settings, I received a very choppy video - how can I install Mythtv 0.20 instead? - Do I need to recompile 0.21? But how? Thanks for help Nightstranger |

Hello forum, after a while I try again to get R5.5 working on my VIA Epia ME6000 Mainboard. Again, I did a clean Auto Install and again I face similar problems like above. When I start "watching TV" I see a black screen for a few seconds, then Mythfrontend crashes. My settings in Mythfrontend configuration TV playback: I added a new output profile with only one setting for all resolutions: Code: Decoder: VIA XvMC #this sounds suitable for VIA CLE266 decoder# Video Renderer: xvmc-blit #nothing else selectable# When I run Mythfrontend in a terminal, I receive those messages: Code: [...] 2011-11-03 21:56:29.871 Connecting to backend server: 127.0.0.1:6543 (try 1 of 5) 2011-11-03 21:56:29.876 Using protocol version 40 2011-11-03 21:56:29.899 TV: Attempting to change from None to WatchingLiveTV 2011-11-03 21:56:29.902 Using protocol version 40 2011-11-03 21:56:33.264 New DB connection, total: 3 2011-11-03 21:56:33.266 Connected to database 'mythconverg' at host: 127.0.0.1 2011-11-03 21:56:33.372 NVP: Disabling Audio, params(-1,2,44100) 2011-11-03 21:56:33.811 VideoOutputXv: Desired video renderer 'xvmc-blit' not available. codec 'None' makes 'opengl,xv-blit,xshm,xlib,' available, using 'opengl' instead. 2011-11-03 21:56:34.480 GLVid, Error: Fatal error here some lines of my xorg.conf (generated during installation): Code: [....] Section "Device" ### Available Driver options are:- # sw_cursor is needed for some ati and radeon cards #Option "sw_cursor" #Option "hw_cursor" #Option "NoAccel" #Option "ShowCache" #Option "ShadowFB" #Option "UseFBDev" #Option "Rotate" Identifier "Card0" # The following line is auto-generated by KNOPPIX mkxf86config Driver "openchrome" VendorName "All" BoardName "All" # BusID "PCI:1:0:0" EndSection [...] $lsmod | grep via Code: via 43520 2

If I recall, it should just be "XvMC" not, "XvMC-blit". Did you get it resolved? I can install 5.5 on a system w/ a Unichrome chipset if it would help... |
