If I take the sources from here https://github.com/Brainiarc7/ffmpeg_libnvenc
I can compile it with working nvenc for a NVIDIA GRID K1.

Your GPU and/or system seems to be out of memory capable to transfer surfaces. Unfortunately, there isn't much I can tell you about that. 1MB per surface should not overwhelm any somewhat modern GPU(So, every NVENC capable one). I also don't have too much of an idea about Non-GeForce GPUs. You might be better of asking Nvidia about this. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
