Ok, I dunno where else to look. I've searched my brains out and tried
just about everything. Using:
Knoppmyth R5A22
SP130000 motherboard
PVR-350
ivtv kernel 0.4.0
ivtvdev - not sure what version, but not current. Found at:
http://membres.lycos.fr/badzzzz/ivtvdev_drv.o.gz
- PVR 350 is enabled in Mythtv
SYMPTOMS:
- Watching TV gives crystal clear playback.
- Watching untranscoded TV recordings is clear.
- Watching DVDs gives extremely poor framerate
- Watching transcoded recordings gives poor framerate
- Watching downloaded mpg videos gives poor framerate
This is all happening through the PVR-350 tv out.
I've tried everything under the sun I can find from a million
different sources, and right now I'm simply amazed I haven't
completely cratered my mythtv installation.
I tried going to the latest ivtvdev drivers, but when I do it fails
with the following:
(II) v4l driver for Video4Linux
(II) IVTVDEV_TST: driver for framebuffer: PVR-350
(II) Primary Device is: PCI 01:00:0
(WW) ivtvdev: No matching Device section for instance (BusID
PCI:0:20:0) found
(EE) No devices detected.
Note that my card is at 0x14 (which translates to 20 I believe)
Switching back to the older driver works fine except for the frame
rate problems listed above.
Any thoughts?
Sounds like you're not using the XV accelerated framebuffer driver for
your PVR-350 output. This is causing your non-MPEG2 recordings
(although I wonder what is happening with your DVD playback, maybe your
DVD player software isn't using PVR-350 acceleration either?) to have
poor performance.
I don't have this card, but I believe you can download the X driver here:
