I dunno about you but libmpeg2 is the only one that plays smooth on mine. standard decoding is choppy and any deinterlacer slows it down too as well as the OSD.
So i'm sad sad sad!

| Post subject: | XvMC in MythTV .20 broken? Solved! |
For those of you looking for a solution, this problem has been fixed in the MythTV SVN branches. Original post: Is XvMC in .20 not working for people? When I enable it on my knoppmyth box it goes really slow and skips a LOT and on my ubuntu pc it goes slow too. XvMC worked for me in .19 and went really fast. I put the output logs from the "mythfrontend -l frontout -v playback" command on my webserver instead of posting them here because there kinda long. Knoppmyth box Ubuntu PC Could someone help me work this out because my knoppmyth box needs it to play smoothly. Thanks! |

I just upgraded from R5D1 and am having the same problem. XvMC causes to video to slow way down and stutter. It's like it's playing at half-speed. I had to go back to the "standard" decoding, and now my CPU usage for X is around 20-30%, and it's crowding MythFrontEnd. Oh, and I DID read your post before I did this. I should have known better... |

Yeah, so it isn't working... So are they trying to fix it or do I have to make a ticket because I really want to get this working again. |

I saw some mentions in the MythUsers list: http://mythtv.org/pipermail/mythtv-user ... bject.html So it's not just us, but I don't see anything definitive there as to whether it's a problem with nVidia or Myth, or something else. I'm running nVidia drivers 8774, btw. |

Jury is still out, but I think I've got a solution that works for me. I'm using Standard encoding, not XvMC. Disabled Vertical Sync in the front-end and everywhere in nvidia-settings. Seems much better now. CPU use of X is higher than with XvMC, but it's still working pretty well. Haven't done enough to really tell whether I'm ahead of where I was or not. (But I'm loving MythArchive and the internal DVD player!!!!) |

When I upgraded to R5D1 I started having problems with XVMC. I found that de-selecting the "Use Open/GL Vertical Sync" option solved the problem and XVMC works fine for me on my FX6200. I'm using the latest nvidia driver -- version 8774. marc |

That's because R5D1 includes MythTV .19. Thornsoft and I compiled/installed .20 which has the problem.

I'm pretty happy right now with Standard library + Bob Deint. X stays at about 9%, and the frontend doesn't max out, even on my dreaded "bills vs patriots" clip that gave me trouble last week with 0.19 + XvMC. It's actually playing much better now, than last week with 0.19. I'm in a happy place right now. Happy happy happy. |

I found a ticket on the mythtv trac for this issue and I added some details to it so hopefully they will fix it soon. The ticket can be found here: http://svn.mythtv.org/trac/ticket/2412 |

I saw they did some work on XvMC in the SVN so I installed it and XvMC is now working! It seems to be a little slower than it was in .19 but it defently useable. Just thought I might let everyone know about this. |

I actually have been working on my own script that compiles mythtv. I posted it today in the howto section http://mysettopbox.tv/phpBB2/viewtopic.php?t=11985 I think everything in the wiki works it just needs to be compacted because it has too many breaks. |

Hmm. I'll give your script a try this weekend maybe. Thanks! |

I performed Cecil's upgrade directions to upgrade my R5D1 to 0.20. This broke my XVMC to the point that HD is unwatchable. Turning off XVMC is also yields a slow system, as the frontend takes up about 70% of my CPU. I heard that the 0.20 fixes fix the XVMC issue, so I tried to install the SVN once via WattoToydarian's script and again using the directions on the Knoppmythwiki. The compile errored out both times I tried it, so I wanted to know if there is another way to apply these fixes outside of compiling the SVN. Can I do an apt-get or something to fix this? Myth is pretty unusable until I can fix this. |
