[FFmpeg-devel] Why this is happening? CUDA ERROR OUT OF MEMORY

[Rodrigo Dal Ri]

Hi guys, 

I am using ffmpeg to transcode some live channels, but I'm having a recurring problem. 
All the time I get a CUDA out of memory error( attached print ), even though the video card has nothing to process. 
I build my ffmpeg following the NVIDIA FFmpeg Transcoding Guide ( https://devblogs.nvidia.com/nvidia-ffmpeg-transcoding-guide/ ). 
I already used the following setups, but in all the error keeps happening . 



First Setup: 
OS: Ubuntu 18.04.3 LTS 64 bits 
kernel: 5.0.0-37-generic 
GPU: Quadro P4000 
driver: 440.33.01 




Second Setup: 
OS: CentOS 8.1.1911 
kernel: 4.18.0-147.3.1.el8_1.x86_64 
GPU: Quadro P4000 
driver: 440.33.01 




Third Setup: 
OS: CentOS 8.1.1911 
kernel: 4.18.0-147.3.1.el8_1.x86_64 
GPU: Quadro P4000 
driver: 435.21 Short Lived 




F ourth Setup: 
OS: Ubuntu 14.04.6 LTS 
kernel: 4.4.0-148-generic 
GPU: Quadro P4000 
driver: 435.21 Short Lived 




Fifth Setup: 
OS: CentOS 8.1.1911 
kernel: 4.18.0-147.3.1.el8_1.x86_64 
GPU: Quadro P4000 
driver: 440.33.01 


According to what I researched this error can be caused by a possible combination between OS, kernel, gpu and driver. ( https://emby.media/community/index.php?/topic/74738-42018-nvenc-sometimes-randomly-fails-with-cuda-error-out-of-memory-out-of-memory/ ) 


Can someone help me? 
Thanks.
