[mythtv-users] How do I use hardware MPEG decoding on my EPIA?

[Morten]

Aloha!

Just a clarifying comment to my post: I *have* compiled and installed
MythTV with CLE266 support (i.e. I have outcommented the options in
settings.pro).

Cheers,

Hi again!

Thanks for your response. I didn't see the options in settings.pro for
the CLE266.

However, I get [not so funny] codec errors now:

  "Unknown codec: 4"

This error arises as soon as I try to use the Epia HW decoder. Using
software, nothing crashes but my video is a bit "bumpy" (pauses
occasionally) due to 100% CPU usage.

Is it because I encode the files in a wrong format (I'm using Hauppauge
DVR-250 as you know), or is the problem hidden somewhere else...?
(What's all those different stream types doing anyway?!) -- I cannot get
any video out at all through hardware decoding as "Live TV" or from
previous recordings.

I'm not quite sure about which XFree86 patches you're referring to.
Basically my system is a modified Mandrake 9.2 system (new kernel):

* Patched 2.6.1 kernel (from kernel.org).
  -- It supports v4l through CLE266 and LIRC as well.
* XFree86 4.3.0 (RPM distributed with Mandrake 9.2)
* MythTV 0.14 (no CVS here).

Regarding libddmpeg.so, I have simply compiled it and copied it to
/usr/X11R6/lib. (It's in the ldconfig path, and ldconfig has been
executed.)

Xine works fine BTW (though VeXP), so I have contact with the hardware
decoder in some way at least....

Here's my module list in case you need it:

Anyway. I ***really*** hope that somebody can help me out on this one,
since it renders my Myth box unusable as a video recorder. Do I need to
install some codecs in order to make this work, or what ???
