Colour losses in Video Window

[Ravindra]

Hello,

I have developed application for Video viewing.
My development machine is i3 , Windows 7-64 bit without graphics card. Uses intel Graphics.
I see everything fine in my development machine. Perfect colors.

When i deploy and install on other desktop machine i saw there are loss of colors. (Colors spread)
This machine has n-vidia graphics card. I saw same problem with my laptop with no graphic card uses built in  Intel ATI Mobility graphics.
I have installed latest K-lite codec pack. I also observed that when i run same video on same machine with
Windows Media Player it is fine. No color loss. It happens on both desktop and laptop.

Please guide me how to fix this issue.

Regards,

Ravindra.

Hello,

Windows Media Player doesn't make use of DirectShow for most video formats so the video stream is generated differently: usually this kind of problems is due to an incompatibility between the color format generated by the DirectShow codec in use and the driver of the video card.

The first thing to check would be the availability from the manufacturer of an updated driver for the video card.

If this shouldn't be enough, in order to give further help it would be convenient receiving a sample video clip reproducing the issue and a screenshot of the DirectShow graph generated by the GraphStudioNext.exe application on the troublesome machine.

You can eventually upload the clip on our FTP site:
ftp://ftp.multimediasoft.com

Once the upload is completed, please, send us a note.
   
Please, send also a log generated by the DxDiag.exe application (usually available inside the \Windows\System32 folder) on the troublesome machine and specify if your .NET application is compiled specifically for "Any CPU" or for "x86".

Hello Severino,

Thanks for guidance.

After doing some work around i changed settings of K-lite codec and problem was resolved.

I changed the video driver settings for H264 to Microsoft.
