[Libav-user] Converting AV_PIX_FMT_CUDA image (AVFrame) to AV_PIX_FMT_BGRA image

[Ахмед Анам]

Hello!

I am trying to use libav API with hardware accelaration (CUDA). I need to transform an AVFrame with AV_PIX_FMT_CUDA pixel format to the frame with AV_PIX_FMT_BGRA pixel format. I tried to create Sws_Context for this purpose (  my_sws_context = sws_getContext(width, height, AV_PIX_FMT_CUDA , width, height, AV_PIX_FMT_BGRA , SWS_BILINEAR, NULL, NULL, NULL) )  but the function always return NULL.

What is the best way to do this? Are there some examples?
