Hi,
It been a while since I updated my EPIA-M frontend to CVS but today I
did.
I compiled using ./configure --cpu=pentium-mmx --enable-xvmc
and all seems well but there are strange hickups in blackback.
This is in the log :

I have xvmc off, xvmc-vld on , bob deint on, extra audio buffering on,
libmpeg2 off, video as timebase on and chmod+s and realtime priority on.
Anyone else seeing these?
I believe there is a patch out there that will up the number of XvMC
buffers when using VLD to 16. That should resolve the problem if you
are only using XvMC w/VLD. I haven't applied it yet because MythTV
should be using 16 buffers already whenever they are available, I
don't want to put in a fix for VLD that will break regular XvMC when
it is VLD is enabled at compile time.

Hi,
Enclosed is the patch. This should only affect XvMC VLD decoding.
As stated it is not ideal. I think that videoout_xv.cpp should
determine how many surfaces the Video driver can support prior
to creating the video buffers and then set the number of
video buffers to this limited to a maximum of 16 ?

Ok, I saw this enter cvs (euh svn, have to get used to that). I'm still
getting pre buffer messages I'm afraid (but a bit less). Anything else I
should try?

Anyone making any progress on this problem? I'm seeing it on an EPIA
SP13000 system about one or twice per second.
I will try and hav a look later this week.
I am currently using MythTv from CVS release date 2005.06.09 with
something like my xvmc_vld_5.patch (a bit more hard coded). This
is working well for me with a Via M10K system.
