Also compile the unichrome driver with  XV_DEBUG and see what logs you get 
then.

32M should be fine.
If mp2player doesn't work then you have a problem you need fixing before 
trying something more complex like mythtv.

What benchmarks are you getting in your X log? In fact what memory have you 
got in the machine and what are the BIOS memory speed settings?

2005-03-20 Thread Bill Weir 
Ivor,

- AGP aperature in BIOS was 64M; I have now enlarged it to 256M - perhaps
this was the wrong direction - not sure what the aperature does. Now -v all
gives continuously repeating messages like this:
2005-03-20 14:24:33.532 Broadcasting free space avail
2005-03-20 14:24:33.536 audio waiting for buffer to fill: have 3072
want 4096

Occasionally interspersed with

2005-03-20 14:24:33.577 Attempting video sync thread restart

- Still nothing notable in Xorg.0.log (I think)

- Yes I have included the EnableAGPDMA in the Device section, per Jaxon
Lee's doc:

Section "Device"

Screen for "VideoCard0" is as follows (depth is 16 or 24? I'm new to X):

Hi,

What size is your AGP window in the BIOS?

Do you have:
Option "EnableAGPDMA" "true"
in your X.org device section?

What res/depth  are you trying to run at?

And - apologies for the bad wrapping. Here's the mythfrontend -v all output

1. Can you try the sample mp2decoder application from the unichrome site,
that 
will test whether your decoding is working.
2. What hardware are you using.
3. Can you get a "mythfrontend -v all" log for the failing playback. 4. What
do you see in the X log when you start playback.

[mythtv-users] Epia M: LiveTV blank

2005-03-20 Thread Bill Weir 
Title: Message



Can someone point me 
in the right direction? Reviewing the users thread I don't see an answer to 
this.
 
I'm trying to get 
MythTV to work on an Epia-M client with Unichrome HW MPEG accelleration, with 
the video feed on a separate backend. When I pull up LiveTV I get a 
blank screen. I can ESC out of it, and when I go to exit out of 
mythfrontend, it won't let me exit. I want to be able to hit LiveTV and see live 
TV. I know it's possible (not a backend problem) because I tried installing 
MythTV 0.17 from RPM's and it all worked, except I got a frame rate of 2 - 3 
frames per second (it wasn't using hardware acceleration).
 
Here's the steps I 
have taken:
 
1. Built a linux 
kernel from source to mirror Terry Barnaby's:  
2.6.9-1.724_FC3
    - 
Made sure agpgart and via_agp were selected (as modules)
    - 
I see these loaded with lsmod
 
2. Built X.org 
X11R6.8.2 from source per instructions on http://dri.freedesktop.org/wiki/Building
    - 
Used latest official source release, not CVS
    - 
Used DRM from CVS
    - 
Used Mesa from CVS
    - 
Result: Able to modprobe drm and see it load
 
3. Built via driver 
and XvMC per Tarry's ""Unichrome Mini-Howto" article at http://sourceforge.net/docman/display_doc.php?docid=21910&group_id=102048
    - 
For the via driver I used Unichrome-X-r30 (an official build) instead of 
CVS
    - 
For the XvMC driver I used release-0.13.3 instead of CVS
    - 
Result: X seems to start OK
 
4. Followed the 
"Unichrome 3D-HOWTO" article by Jaxon Lee at http://sourceforge.net/docman/display_doc.php?docid=26963&group_id=102048
    - 
Result: StartX works, glxinfo indicates "direct rendering: Yes", glxgears shows 
gears just fine, frame rate around 200fps
 
5. Built MythTV 0.17 
from source per instructions
    - 
Made sure the XvMC_VLD lines were uncommented in 
settings.pro:
# XvMC_VLD support, 
modify as necessary. Incompatible with normal XvMC 
support.    # Used for hardware 
accelerated decoding on VIA EPIA-M (and other) 
boards.    CONFIG += using_xvmc 
using_xvmc_vld    DEFINES += 
USING_XVMC USING_XVMC_VLD    
EXTRA_LIBS += -lviaXvMC -lXvMC
 
Here's some
