#10767 closed Bug Report - General (Fixed)

Video Playback has extremely high contrast - unwatchable

Reported by: david@… Owned by:
Priority: minor Milestone: unknown
Component: MythTV - Video Playback Version: 0.25-fixes
Severity: medium Keywords: video playback high contrast .25
Cc: Ticket locked: no


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

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?

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.

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)

This device I'm using:

(Intel GMA 3150)

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

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).

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?

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?

You're using a version of MythTV from before the fix. Please install the Mythbuntu-repos package, as described at , 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.
