Hi there， I am currently using ffmpeg qsv_h264 and opengl redering on windows ， is there any api that can transfer the decode frame to opengl texture to make the 0-copy rendering, thank you.

av_hwframe_map() may map a qsv frame to a d3d11 frame, then you may use the d3d11 frame in your app. See https://github.com/FFmpeg/FFmpeg/blob/master/libavutil/hwcontext.h#L543-L583

very appreciate it, thank you, and I'll try to research how to share the memory for d3d11 and opengl.

By the way, Do mediaSDK has the similar function like the link refers for cuda https://www.qtav.org/blog/cuda_0_copy.html.
