Hey @zydjohnHotmail, unfortunately this is not implemented yet. I'm planning to add it in v3.2 hopefully soon. I've already the code whice gives you the extract frames but that wouldn't be enough as it will happened in GPU and you need to bring the frame back to CPU/memory (requires pixel shaders as well). You could force it though to use RGB sws_scale. If you are up for coding check this code here

Hello:
I looked at the code, but I think it was in C++, which I already forgot many years ago. Anyway, I will try to find other way to do, but if you can release new version and add the feature, let me know.
I need some C# code with good performance, since my real job will need such feature for much bigger video files.
Thanks,

The code is actually in c# that I gave you even the title says c++. It would be easy to write it without performance that's why I want to write it once for good with hardware acceleration and pixel shaders. I will leave this open to remind me when the time comes ;)
