Concise Description of the Issue: The output image when using d311 is so brightness black are grey and red are so fade.


Look at the attach file to download screenshots.

Here you can download a zip where i decode some frames with d3d9 renderer and d3d11 renderer. One also with the original image without h264 compression. We can see that d3d9 is really close to the original, just a litlle noised due to h264 compression but the d3d11 one is really too much brightness. Black is grey and Colors are fade.

Does anyone have idea why this decoder has problem?


I have an other decoder which used Nvidia GPU card and with d3d11 i have not this problem.


Thanks for your response.

Hi Paul,

so just to be sure, it seems to me the decoding, but about decode+playback. is that correct?

The problem with Decode+playback can be related to screen settings, so d3d9 is not reflected and enable all the color enhancement assumed to be enabled on platform.
