Hi Marton,
TL;DR
xcompgrab uses more CPU but produces much better streams than x11grab.
I have the following CPU usage performance report (on my i7-8700k,
Nvidia 2080 Ti RTX, governor set to 'performance', on Ubuntu 18.04 using
Gnome shell).
The capture has been a surface area of 1720x1376 fo

Hi Marton,
Capturing at 60 FPS 1920x1080, the difference is even more noticeable:
x11grab is choppy, xcompgrab is smooth (this time I used H264 ultrafast
to encode).

The change to the documentation would be unnecessary if James' patch
https://ffmpeg.org/pipermail/ffmpeg-devel/2020-April/260984.html were
applied. But it is only internal documentation, so changing and
reverting it is easy.

Allows shifting of subtitle display times to align them with the video.
This avoids having to rewrite the subtitle file in order to display
subtitles correctly when input is seeked (-ss).
Also handy for minor subtitle timing corrections without rewriting the
subtitles file.
