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'm using the ffmpeg-python library(https://kkroening.github.io/ffmpeg-python/), but the error happens both by calling the library and using the command line directly, for example: ffmpeg -hwaccel cuvid -c:v h264_cuvid -i rtmp://... -c:a ac3 -vf scale_npp=1280:720 -c:v h264_nvenc -sc_threshold 0 -g 60 -keyint_min 30 -hls_time 6 -b:v 2800k -maxrate 2800k -bufsize 4200k -b:a 128k -r 30 -f hls pipes/... 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 Fourth 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.
