Svideo Tearing

While mplayer SD video as viewed on my CRT is excellent, I get
tearing during fast pans in clone mode viewing SD video through
svideo-out on a standard TV. I have the same results with both a
GeForce FX 5500 and GeForce FX 6200. I have tried repeatedly to get
a single response from the Nvidia support forum but have been
unsuccessful to date. I have a WinTV PVR 500 capture card and the
mpg files it generates are excellent. This has been proven by
watching the video on a Windows box using Windows Media Player and a
Samba mount of the file.

I need to demonstrate to my spouse that my MythTV investment is
worthwhile. The tearing annoys her and while the video quality on a
PC is excellent, watching shows using Tapeworm on her PC will not cut
it for her. I am running all the most recent versions of
MythTV. Any help would be most appreciated.

My xorg.conf and .nvidia-settings-rc files are listed below. I am
running FC5, 2111 kernel, and the 8756 nvidia driver.

It's just a guess, but "0/XVideoBlitterSyncToVBlank=0" might be
relevant. See if you can enable that option. I'm not sure what the
difference between Xvideo textures and blitter is or what MythTV uses.

Also, looking in nvidia-settings on my desktop (which currently only has
a VGA CRT connected), I see the setting "Sync to this display device,"
which seems to correspond to your XVideoSyncToDisplay attribute. It
seems to me that you need to select the TV as the display to sync to,
but I don't know what "256" means.

Re: Svideo Tearing [In reply to]

Thanks,

I will try it.

Anyone else have any ideas?

Hi Mache,

By tearing, could you mean it's not interlaced? There are a variety of
de/interlacing options available in myth..

However I am probably misinterpreting the problem,

Re: Svideo Tearing [In reply to]

Tearing has nothing to do with interlacing.

Tearing occurs when the painting of pixels on one section of the
screen lag behind the painting of pixels to the rest of the
screen. In my case it appears that on fast side to side pans, blocks
of pixels at the top of the screen noticeably lag behind the rest of
the updates on screen. It is a slight lag, but is an annoying
artifact none the less.

This only happens on svideo out and not on the CRT.

I see what you mean now, thanks for the explanation :-)

One video output signal and two refresh rates = tearing on one display...

What do you mean by that? Where are the two refresh rates coming into
play? I have a similar problem, I am using a Grandtec VGA->Component
convertor and I get this problem as well, and I'd love to fix it... :)

Re: Svideo Tearing [In reply to]

How do you set it up so it tears on the CRT and not on the TV?

Make the CRT the primary display. See the driver README (
http://download.nvidia.com/XFree86/Linux-x86/1.0-8762/README/index.html
) for more info.

Oops. I read that wrong. Set up whichever you want to not have tearing
to be the primary display. (Based on your question, you'd set the TV to
be the primary display.)

Re: Svideo Tearing [In reply to]

It may be your NVAGP settings. Running in AGP1x can (and has for me
many times in the past) caused this type of problem.

Here's mine, which works great at 1080 with no tearing.

Section "Device"
Identifier "Videocard0"
Driver "nvidia"
VendorName "Videocard vendor"
BoardName "NVIDIA GeForce FX (generic)"
Option "RenderAccel" "1"
Option "NvAGP" "3"
Option "XvmcUsesTextures" "true"
Option "ConnectedMonitor" "TV"
Option "IgnoreDisplayDevices" "CRT"
Option "TVStandard" "HD1080i"
Option "TVOutFormat" "COMPONENT"
EndSection

I've had problems with tearing too. As you say,
assigning the primary display to the preferred device
so it gets the video overlay is key, but my
understanding is the FX6x00 series doesn't support an
overlay like the FX5x00 series. I have a 5200 so I
don't know if you can completely eliminate the problem
with an FX6x00.

Also, I found OpenGL sync to make a huge difference.
I'm running the latest nVidia binaries with FC5 and
the drivers seem to be working with OpenGL sync. Wish
I could get my Via Unichrome Pro system to works as
well :(.
