I tried posting this to mythtv-dev but it never made it (maybe because I
am not subscribed?) I am reposting to mythtv-users...
Hi,
I am trying to get the VIA CLE266 HW decoder working with mythtv-0.15 on
a 2.6 kernel. Everything is working when I use software decoding. When
I select HW decoding (from the settings) mythfrontend dies.
Here is what I have:
. PVR-250 (on a remote server in the other room)
. EPIA-M10000 (Nehemiah client box - diskless - dhcp boot)
. 1.4 build of gentoo
. 2.6.6 kernel
. patch-2.6.6-epia1.bz2 (from: http://www.alterself.com/~epia/wiki/tiki-index.php)
. latest alsa
. libddmpeg-1.6 (from emerge libddmpeg)
. ivtv-0.1.9 (from ivtv emerge)
. xfree-epia (from xfree-epia-4.3.99.902-r6.ebuild)
. mythtv-0.15 (from download today)
. VIA cle266 support is enabled in settings.pro
. UseViaSlice = 1 in table settings (it works fine when UseViaSlice = 0)
. I am running as root
When I try to play a recording from the server I get (in the mythfrontend log):
2004-05-28 00:49:09 mythfrontend version: 0.15.20040505-1 www.mythtv.org

then mythfrontend SIGSEGVs.
Please let me know what you suggest... or if you need any additional
information (like my kernel .config or other lib levels etc.).
Thanks!
Dick
