 Summary of the bug:
 I have been using the -fps_mode option together with -fps_max to to allow
 my videos to have variable framerate while at the same time limiting it to
 30 fps, similar to how handbrake have a peak framerate setting. But now
 when I do that it gives this error message "//One of -r/-fpsmax was
 specified together a non-CFR -vsync/-fps_mode. This is contradictory.//".
 I found out that this was a recent change, specifically
 [https://github.com/FFmpeg/FFmpeg/commit/260f3918937463f1b90e1b77cba80b917f3cb8c1
 This] commit on git master. The description of this commit talks about how
 -r should always give constant framerate but it doesn't talk about
 -fpsmax. If this is intentional I would like to know how to achieve
 something like handbrake's peak framerate option with ffmpeg with this new
 restriction. Thanks in advance!

 How to reproduce:
 {{{
 % ffmpeg -i input -fps_mode vfr -fpsmax 30 -c:v libx264 -crf 20 -c:a copy
 output
 ffmpeg version git-master
 built on 22/1/2023
