Hello. I'm trying to use ffmpeg to generate test images, and I'm not getting very fast performance. Is there any way to improve speed? If Lavfi is the problem, then is there any other high-performance virtual input I can use instead? I would actually prefer to use something more complex, like mandelbrot, but I just changed to solid red color for this test.
Example command: ffmpeg -f lavfi -i color=color=red -t 60 -pix_fmt rgb48le -y -s 3840x2160 ffmpeg\%4d.tiff ffmpeg version N-90610-g2accdd3871 This runs at 6fps. My CPU usage is only about 1% and my disk has plenty of bandwidth (3000 MBps). Thanks, Elliott _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
