Hello
I have ubuntu 18.04 server where i have install ffmpeg and compile sdk as
well as all requirement of NVIDIA tesla M 60 driver .
*1.Issue is whenever i define gpu , both gpu 1 and gpu2 take the process *
*2.ffmepg mostof the time shows frame drops and video buffer *
*Here is have attached all the output and script *
