[FFmpeg-user] Lossless h265/YUV420

Hi everyone,

I am trying to use NVDEC to speed up my transfers of OpenGL related stuff (3D Objects), that means treat these objects as images and encode them. As stated at https://developer.nvidia.com/nvidia-video-codec-sdk#NVDECFeatures, NVDEC only supports the YUV420 pixel format, so I can’t put my numbers in RGB – Image files and encode them.

My question is, is there a possibility to create images with yuv420 pixel format, and feed these images to ffmpeg, or do I have to write my own program, where I put my data in the YUV planes and encode them?

I am grateful for every pointer in the right direction!
