Re: Improving frame rate of screen-recording
Could the reason the recording gradually slows down be because appending data to a large (and growing) file is slow (I have no idea if it is, just guessing)? I tried saving the output to /tmp (which I have running in RAM because it's mounted as tmpfs) but the increase in write speed didn't help much or at all (and I should think my hard drive can handle writing ~50mbps to disk anyways, for RAM it should be no problem).
If it does have to do with the increasing file size, is there a way I can get ffmpeg to create a new file after, say, 200 MB is written so it never has to write to a file larger than that?
I also tried setting my game to run at 1/2 frameskip and set ffmpeg to record at 30 fps, but the same exact problem occurs there too.

The whole thing is so patently infantile, so foreign to reality, that to anyone with a friendly attitude to humanity it is painful to think that the great majority of mortals will never be able to rise above this view of life.
