Almost certainly directly or indirectly related to this "fix" :

http://code.mythtv.org/trac/changeset/4cd818657100d13a813dfa7a8a44201184c49d71/mythtv

My device will no longer play video properly. I don't 100% recall my
previous setting (CPU- if I recall), but video playback now has an
EXTREMELY high contrast. If I switch to openGL, playback is normal;
however, my underpowered front-end video card can only support openGL for
SD and not HD (it stutters).

I should note that HD videos play fine outside of myth in VLC (this is not
a drivers issue).

So, is there a workaround to manually change the video playback settings
without using one of the canned examples? Or are .25 users stuck with
generic settings which are unusable for some systems?

Comment:

Resetting to defaults.

We need to know what hardware you're using, a copy of the frontend
playback logs, and ideally a sample of the video. Assuming these are TS
recordings from a digital tuner of HDPVR, 'dd' a chunk of it, and test it
with mythavtest to make sure it causes your issue.

Comment (by david@…):

I'm not sure what good the video will do. It's any normal video that I
play. When in the setup wizard, I can reproduce the issue with the
Blender video.

As for the logs (on debug)

http://dl.dropbox.com/u/431264/slimprofile_w_highcontrast.log

This device I'm using:
http://www.newegg.com/Product/Product.aspx?Item=N82E16856119051

(Intel GMA 3150)

I'm not sure how to get my submitted hardware profile.

Comment (by mdean):

This is actually almost definitely related to
2e7722d436dd8348d9131b069bf963a96b04a1dd (and unrelated to Playback
Profiles/the removal of the broken Playback Profile groups from the
database), and you likely just need to reset your Playback Picture
Controls (hit F during playback, then fix the appropriate settings (may
require hitting F multiple times)).

It is also likely related to #10609. As in #10609, we need the output of
xvinfo and mythfrontend -v playback (while playing back a video).

Comment (by mdean):

And when I say "related to 2e7722d43", that means the issue should be
fixed by that change. What revision of 0.25-fixes are you running? Your
frontend log doesn't provide a useful revision number, but does
mythfrontend --version do so?

Comment (by david@…):

CTRL-F (disable night mode) makes the contrast better, but it certainly
isn't good enough for normal watching.

I had some time today so I downloaded 12.4 Mythbuntu and reinstalled from
scratch. Same dealio, so it's repeatable.

Here's mythfrontend --version:

How do I get you the output of xvinfo exactly?

Comment (by mdean):

You're using a version of MythTV from before the fix. Please install the
Mythbuntu-repos package, as described at http://www.mythbuntu.org/repos ,
and update to current 0.25-fixes.

You can close this ticket, the fixes repo did the job.

Thanks for hunting this down for me.
