Set the encoding level restriction (from 0 to 62) (default auto) Set the encoding profile (from 0 to 3) (default main) Set the encoding tuning info (from 1 to 4) (default hq) Set the encoding preset (from 0 to 18) (default p4) Supported pixel formats: yuv420p nv12 p010le yuv444p p016le yuv444p16le bgr0 rgb0 cuda d3d11

Supported hardware devices: cuda cuda d3d11va d3d11va This is what I get with ffmpeg -hide_banner -h encoder=h264_nvenc Encoder h264_nvenc :

c:v h264_nvenc -cbr true -b:v 9M -preset slow -c:a copy -gpu 1 -f flv 'rtmp://youtube_server/streamkey' c:v h264_nvenc -cbr true -b:v 6M -preset slow -c:a copy -gpu 1 -f flv 'rtmp://facebook_server/streamkey' c:v h264_nvenc -cbr true -b:v 6M -preset slow -c:a copy -gpu 1 -f flv 'rtmp://twitch_server/streamkey' ffmpeg -hide_banner -i rtmp://localhost:1935/live/stream Input encoding is done by the GPU 0 and passed to MonaServer on localhost. GPU 1 is Nvidia Quadro p1000 with patched drivers to be able to do more than 3 concurrent connections. Is there a way to improve the quality of the output without increasing the bitrate? Also, is there a way to improve the quality of the code using tee?Īfter reading everything I could find about ffmpeg and nvenc I was able to write these commands and they work just fine if there is no action (in-game lobby where not too many things moves), as soon as I get some action, the quality of the output drops -> artifacts all over the place.
