However I thought that GPU Encoding might help here, but I don't get this working. The frames are like 5 seconds behind and then have lots of bugs in them so it takes at least 10 or 15 seconds to see the hole frame (the video is a "live stream" from a canvas). ffmpeg -f image2 -r 30 -i 09d.jpg -vcodec libx264 -profile:v high444 -refs 16 -crf 0 -preset ultrafast a.mp4. And I want convert local gif to mp4 using ffmpeg, so which encoder works for me ffmpeg h. h264amf h264nvenc h264omx h264qsv h264v4l2m2m h264vaapi h264videotoolbox I do not know what's the difference between. configure -list-encoders grep 'h264', you can see them.

'-f', 'mpegts', // output container format '-pix_fmt', 'rgba', // input pixel format Those are my settings: var ffmpegArgs = [ What I do is, I pipe raw data direclty into ffmpeg to output them to a udp stream.
I'm currently trying to use FFMPEG with Hardware/GPU Encoding with the H264 Codec.
