> So far i have the following command: > ffmpeg -y -loglevel info -f lavfi -i aevalsrc=0 -f rawvideo -pix_fmt > rgb24 -video_size 1280x720 -framerate=25 -i "-" -f flv -acodec aac -vcodec I don't think this is supposed to work. > h264_nvenc -profile:v high -vf "fps=25,format=yuv420p" -minrate 3000k Careful with the fps filter: If input fps == output fps, don't use it to be on the safe side. > -maxrate 3000k -bufsize 6000k output.mp4 -g should set the keyframe interval.
