--------------------------------+--------------------------------------
My build is based on the master branch and with CUDA 10.2 (from CUDA
toolkit cuda_10.2.89_440.33.01_linux) . When using this build to encode a
mp4 sample , ffmpeg run at 0.1fps on a Tesla T4 instance, while it works
fine on Tesla M60 or Tesla V100 instance
