[FIXED] Grayish black bars

After upgrading to windows 7 x64 and using EVR as renderer (overlay mixer isn't an option anymore) I see the entire bottom black bar being gray and part of the right top bar.
Self explanatory screencap:

The partial gray top bar isn't always here between computer reboot, the bottom one is ALWAYS here.
Using any decoder (ffdshow alone, coreAVC alone) in any color output (RBG32, YUV...) with any resolution (SD, HD720p/1080p)

There is a temporary solution to the problem: pressing "5" on the numpad (pan-scan reset), everything turn out black, but getting out from fullscreen and getting back to fullscreen gets the problem back
I previously seen the problem on XP using VMR7, but a bit differently (player element was painting gray where they were moved)

I see those bar clearly since I perform a YUV->RBG32 conversion that move the correct luma of 16-235 to 0-255 (gray to back and white)

Other maybe useful info:
GC: Ati Radeon X1650
Display: Samsung 20" 1600x1200 DVI
OS: Fresh windows 7 x64
Preferred decoder: coreAVC->ffdshow->upscale/RBG32conversion->vsfilter

Thank you for reading.

same problem for me: (it's purple for me)
same problem for me: (it's purple for me)

and someone already report it to bsplayer support team but they did not manage to reproduce it.

and it's also happen for me on my friend's pc.
something is really weird with bsplayer.

I think bsplayer pro has some problem with coreavc pro.

I really appreciate bsplayer team and I hope they will manage to fix it.

Well looking further in detail the problem we can see that it is a YUV output problem.
As You may know a computer screen work on the color space of:
Y:0-255 CbCr 1-255 against TV: Y:16-235 CbCr 16-240
convertion tout RGB: 0-0-0 and 15-0-15 (dark purple some red+blue)
Witch mean that we send to the TV an image with grayish black and grayish white. So if whe send the image to a TV we won't see the problem, but on a computer it's not the case.
So the problem is probably mainly in our video drivers/hardware system. after for the rest of technical detail it seems a bit complex.
This weekend if I have time I will try to test alternative configuration (VGA instead of DVI, single-head/dual-head, hardware overlay parameters etc...)

I did not get this problem (purple bars) with ffdshow alone.
(but I get it with coreavc pro).
but maybe you are right.
anyway we need to wait for Ico-man respond.

Got the opportunity to test a few other things.
You where right about ffdshow alone (using libavcodec of ffmpg-mt).
But, since I use coreAVC and ffdshow in the same time (coreAVC decode, send to ffdshow, and ffdshow perform upscale and rgb32 conversion). (directvobsub has no effect)

What it mean is that it's no the link between bsplayer and coreAVC and therefore maybe coreAVC fault.
I also tried falling back in VGA, changing COLOR ICC profile, no change.

I also performed a massive modification of the video stream in ffdshow, removing any flag information (aspect ration/interlacing etc...) to be sure coreAVC don't say anything to bsplayer) but didn't worked

What’s left to test is changing software version (older CoreAVC, and bsplayer)

EDIT: Tested coreAVC 1.8.0, same problem (CoreAVC failed to work under 7)

I guess it will be fixed in the next bsplayer version v2.51 (w/ coreavc 2.0).

shablul123 1st December 2009 03:04 PM

OK it will be fixed in the next version!
I have got this email from bsplayer support team:

this should be fixed in new beta, which will be released sometime today.

Great, with the very imminent release of coreAVC 2.0, it will be perfect :)

shablul123 3rd December 2009 03:09 AM

v2.51b is out.
they fixed the problem.

neb1236 3rd December 2009 12:53 PM

I confirm \o/
Thank you BSplayer team for your hard work.
