Corrupted bottom line of pixels.

I have a Zotac ION based frontend, and lately I sometimes get
corruption in the bottom line of pixels. I'm running in 1080p50.
I've seen the corruption when playing 576i content via vdpau,
and also with GOOM in mythmusic. Rebooting seemed to fix
it last time I tried it. It's only recently that it's started
doing this, and it might correlate with putting the frontend
in a confined area where it may have been overheating, although
now I have it back in a cooler environment and it's still
sometimes doing it.

Anyone else seen similar? Anything I can try to fix it?

Cheers,
Paul.

Are you seeing pixelation or ant fights?

I would get a couple pixel width line of black and white static (ant
fights) across the top of my screen.
Adjusting overscan hides it.

This is probably caused by closed captions and like the other poster
said adjusting the overscan to hide this fixes the issue.

I don't think it's closed caption, because it's the bottom line
not the top. It looks like the bottom line is showing part of
another line from elsewhere in the image, repeating the partial
line 3 or 4 times. I've had it with the GOOM effect in mythmusic
too, so it's not in the source.

Cheers,
Paul.

I've noticed more of a pattern to it.

1) All but the bottom line of pixels are correct.

2) The last quarter of the horizontal extent of the bottom line is correct.

3) The first three quarters of the bottom line are copies of the last
quarter.

No one else ever seen this? I wonder if my ION board is faulty.

I have the same issue when viewing recordings. I don't use mythmusic
so can't tell for it.
For me, it depends of the content viewed and is not always present.
I'll look for overscanning to go around this problem.

Brilliant, thanks. That means I don't have to try to return the ION,
and go back to an old mobo while waiting for it's return or replacement!
And perhaps it'll disappear in later driver releases (or could it
even be a MythTv bug?).

Do you mean overscanning in my TV? I didn't really want to do that
because then the ION is scaling 576 to 1080, and the TV is doing
a second scaling from 1080 to 1080 + a bit, whereas the TV is
nicely 1-1 without overscanning. I think I see a difference
in quality, although I guess I'm not sure.

Cheers,
Paul.

That sounds like a different issue. Sounds like it's being introduced
in the recording process. I guess you could have my problem too, since
yours would mask mine.

I have this as well, but only for 1080i recordings (I currently let the STB feeding the HDPVR output native format). It definitely seems to be in the recording, because the preview image in the Watch Recordings screen shows it to. Usually its blinking/flashing green dots/lines at the bottom of the screen.

The HDPVR recordings from ESPN (720p) don't exhibit it.

Not sure what to try. I'm running 1.5.6.1 firmware in the HD-PVR.

Hmmm... Seems like my conclusion it is actually in the recording is wrong. Playing on my Mac w/VLC shows no green lines on the bottom, and player doesn't either. So its something in how MythTV is processing the image -- both for preview generation and playback -- which is causing the corruption.

Interesting. Does the preview generation also involved VDPAU?

I wonder how many forms of this we have. So far two have been descrived:

1) The whole bottom line is incorrect, and is a solid single colour.

2) Only the first 3/4 of the bottom line is incorrect and consists of
3 copies of the last 1/4.

Who's seeing which? I see No 2.

Paul.

I would say I'm seeing #1, but its really more flashing dots on the bottom row of pixels (where most often there are so many dots that it forms lines), and its not always the same color. Mostly green, last night I watched a show with blue and pink. Its not usually mixed, however.

Still collecting more data. Might switch the STB to 720p and see if that really makes it go away. I see the corruption on all 3 TVs (all are driven by IONs, one zotac DIY and 2 revo 1600s).

Sounds like Closed Captions Data to me but I thought that was normally at
the top of the screen?, it probably makes sense that the HDPVR just displays
it...

Nope, its definitely not closed captions data. That shows up as white and at the top.

The puzzle to me is why it doesn't show up when mplayer plays it back.

In some case where I've seen the problem, I've downloaded the file to my
PC using Mythweb, and played it with Nero Showtime. Never seen the
corruption there.

Of course that is just ruling out the source, not VDPAU.

Good point, my mplayer test was flawed: I didn't force mplayer to use vdpau. I need to try mythtv vdpau without deinterlacers as well.

Ah that's a thought. I'll try that too when next home, although I'm
playing SD material and it seems to be one screen line that's corrupted
rather than one source line... I think... I'll double check that too.

Hang on, I nearly forgot. I've seen the problem when displaying GOOM
in Mythmusic, so it has to be in the scaling stage (I have mythmusic
set to use a factor of 2 because the ION can't keep up otherwise).
Presumably VDPAU isn't involved in scaling GOOM visualisation.

Any more news on this? Has anyone opened a bug in trac?

I confirmed it doesn't happen if I set the deinterlacer to None (or force the video sync to progressive).

I'm running a fairly old nvidia driver (190.<something>), so I wanted to make sure the newer drivers don't fix it, but haven't had a chance for downtime on the box.

David.

Oh right. I'll try that next time I see it.

I'm using latest Minimyth that has 195.36.31

Cheers,

That doesn't fix it for me. I can set to progressive and the bottom line
is still corrupt.

Are you seeing exactly the same problem as I am: four copies
of the same 1/4 line across the bottom?

Cheers,
Paul.

Hmmm. maybe not.

Mine looks more like a bunch of stuck pixels -- though the color they are stuck to differs between recordings. Usually green, but I've also seen blue or pink.

Again, only happens w/1080i recorded from the HD-PVR and a deinterlacer enabled.

I switched the STB to 720p output, so it dropped down my list of things to worry about.

David.
