Hi I'm trying to encode a live 8K footage from a decklink 8k p ro card using nvenc hevc codec but i get Decklink input buffer overrun! always. I have tested outputting to -f null /dev/null but i get the same I tried with the -thread_queue_size option too without luck. My 2 pci ports are 16X each on a 32 lines pci express 3.0 mother board.
My test command : ffmpeg -thread_queue_size 5096 -f decklink -r 30000/1001 -rtbufsize 200M -i 'SDI1' -vsync 1 -c:a aac -b:a 128k -c:v hevc_nvenc -b:v 50M -preset fast -profile main -level auto -f null /dev/null Any ideas on how to troubleshoot this ? -- Sent from: http://www.ffmpeg-archive.org/ _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
