Re: [FFmpeg-user] ffmpeg ip cam stream with drawtext
I was looking at this, it lists decode capability but not encode. https://trac.ffmpeg.org/wiki/Hardware/QuickSync As for putting text on the video, there's a library called OpenCV that lets you put text on the video and do lots of other things. It probably would be too much trouble though, since OpenCV can read an RTSP stream, but can't send it to youtube. You'd have to capture the OpenCV window or something.

The CPU was unable to do the curves filter at 30fps above 1080p. We put my GeForce 1060 3GB in the computer, and it doesn't use much CPU at all now. Here is the command we're using that uses the Nvidia GPU. c:\ffmpeg\bin\ffmpeg1.exe -re -rtsp_transport tcp -y -i "rtsp:// admin:12345@192.168.1.64:554" -f lavfi -f dshow -rtbufsize 2000M -thread_queue_size 5096 -i audio="virtual-audio-capturer" -c:a libmp3lame -ab 128k -ar 44100 -bufsize 5096k -c:v h264_nvenc -preset:v hq -rc cbr_hq -b:v 12M -buffer_size 1k -vf curves=psfile=c22.acv -f flv "rtmp:// a.rtmp.youtube.com/live2/abcd-efgh-1234-1234" If you an afford it, a GPU would help a lot.
