Can watch TV through mplayer but not mythtv

Post #1 of 7 (1685 views)

I've been following Jarod's directions for setting up a PVR-[23]50
system (http://pvrhw.goldfish.org/tiki-pagae.php?pageName=rh9pvr250).
I've nominally finished the installation but appear to have some
configuration problems. I can watch TV through mplayer at the shell but
not through mythtv.

Details:

1. I can watch TV through "mplayer /dev/video0". My
"/etc/mplayer/mplayer.conf" contains "vo=dga".

2. I have configured my capture card within mythtv as described.
Specifically, under "Capture Cards", I have specified /dev/video0 with
Default Input "tuner" and card type "Hardware MPEG Encoder Card".

3. Under "Input Connections", I enabled /dev/video0 (Tuner0 -> cable)
where "cable" was defined under "Video Sources".

4. When I start "mythbackend", I get the following message:

Probed: /dev/video0 - Composite 0
Probed: /dev/video0 - Composite 1
Probed: /dev/video0 - Composite 2
Probed: /dev/video0 - Composite 3
Probed: /dev/video0 - Tuner 0
Probed: /dev/video0 - Composite 4
Probed: /dev/video0 - S-Video 0
Probed: /dev/video0 - S-Video 1
Probed: /dev/video0 - S-Video 2
Probed: /dev/video0 - S-Video 3

5. When I "Watch TV" through mythfrontend, the picture is messed up,
similar to what happens if I run mplayer from the shell without
specifying vo, which leads me to ask...

How do I tell mythtv to give mplayer the argument "vo=dga"? I specified
it under "Video Settings", but it's not clear to me that's used for live
TV. Does mythtv use /etc/mplayer/mplayer.conf?

I would be most grateful for any advice.

I'm not a wintv pvr user - but I don't think you should have it
specified as Hardware MPEG decoder in the setup screen. That I think is
only for Matrox cards.

That is absolutely, completely, utterly false.

MythTV doesn't use mplayer. You need to get a working video card that
supports Xv for video display.

Hmmm, then I was absolutely, completely, utterly wrong :) I absolutely,
completely, utterly apologise - I'm struggling with my own cvs bugbears
at the mo, shouldn't get involved in other threads without thinking

Myth doesn't use mplayer (except in MythVideo, where it's called as an
external player for non-Myth video files). For a more accurate test, call
mplayer with "vo=xv". You'll probably get the same messed-up picture that
Mythtv gets. Myth uses the Xv output extensions to display video, not DGA.
Also, try running "xvinfo" from a terminal and see what it tells you.

i think myth wants to use -vo xv (X video extensions) no matter what you
do. so.. fix xv extensions in Xfree and try it maybe...?
