Re: [mythtv-users] prebuffering pause on live playback

Thanks for the info.  It sounds like this hardware should support what I'm trying to do, so I guess I must have something miss configured.  I'm using Fedora Core 3, getting mythtv/drivers from the ATRpms testing repository.  I used the link that you mention to get the display unichrome drivers installed, but that was where I had difficulty.  I couldn't use the kernel RPMs because they were compiled i686, and my Fedora install uses a i586 kernel.  I also had some problems with some of the libraries because the RPMs conflicted with the xlib package.  The xorg.conf didn't work either because it's setup for PAL, and my TV is NTSC.

How do you control hardware acceleration on the display?  How do you tell if it's accelerated (other than CPU usage).  I think my problem is that it's not using hardware acceleration on display.  Also, what resolution(s) do you hare the X server set at.  I see discussion about all kinds of different modes, but all I can get my X server to accept is 800x600.  All the other modes are rejected for one reason or another (usually a message that says something like "TVencoder does not support that mode").

Thanks for the info,

Brian

Hi - I have an M6000 and have just finished setting it up with version
0.18 . MythTV is fantastic despite my fears over the relatively
underpowered hardware.

I am running Gentoo and have an Avermedia 771, so am getting an mpeg2
stream which means less CPU used for mpeg2 decoding with the unichrome
mpeg2 card. I am running backend and frontend on the same box with no
problems.

When I run anything without hardware acceleration, the CPU maxs out and
the pictures lag a bit. When acceleration is on, I get about 40% idle and
the picture is perfect. Even when I play an xvid file with mplayer and an
xv driver, I get 50% idle.

In short, the M6000 is fine for all video formats and can run the full
mythtv package on it's own as long as you have hardware support.

It sounds as if you may not have hardware acceleration support on - have
you compiled Myth and your kernel with Unichrome support? What distro are
you using?

NOTE: Even when hardware acceleration is on, you will get "prebuffering
pause" messages. I have got over this by running mythfrontend  with nice -
eg "nice -n -2 mythfronend".

As for your Xorg, here is a really good page that will sort out TVout. I
am using the guy's xorg.conf file and the picture is fantastic.

Hope this helps.
