Can I use ffmpeg to record my Xorg desktop (without audio) at one frame a second into a video file that will play back the frames at 30 frames per second without requiring a conversion process?
The following command records my left display at 1 frame per second but the resulting video will advance the video frame once per second.
ffmpeg -r 1 -f x11grab -s 1920,1080 -i :0.0+0,0 -vcodec libx264 -crf 0 -preset ultrafast -threads 0 out.mkv
- Make screenshots at an interval, then combine videos using mencoder
- As #1 but using ffmpeg
- Record a video of the desktop with ffmpeg at 1 fps or less, if the encoder supports such numbers and speed up the video afterwards via ffmpeg.
If it is not possible with
ffmpeg alone, would a combination of
ffmpeg or some other tools allow the time-leap video to be ready as quickly as possible after ending the recording?
