FFmpeg NVENC GPU Memory Usage

Hi, I transcoding video on NVIDIA QUADRO K4000 in Ubuntu (ffmpeg version is 2.7.1, NVENC SDK 5.0.1). GPU Memory usage for one stream is 100 MB, but when I run the same transcoding process with the same ffmpeg parameters on another computer with NVIDIA GTX 980 TI (ffmpeg version is 3.0, NVENC SDK 5.0.1) then GPU Memory usage for one stream is 170 MB.

Why such a difference in memory usage? Can I decrease a GPU Memory usage on GTX 980 TI to 100MB for one transcode process as on QUADRO K4000?


try use ffmpeg 2.7.1 in gtx 980

Thanks for the comment. I tried this and I received the same results.
