ffmpeg version compatibility

[legraphista]

Hey, awesome project and i've been waiting for something like this for the past 5 years :D

I am running ffmpeg (and shared libraries) at 4.2.4, and I have some build issues

Is this compatible only with ffmpeg 5+?

Developed on ffmpeg master. But I think it will compile with FFmpeg 5.0 too (master FFmpeg have some source filters fixes for setting frame_rate of outlinks, so if you can, pick that one instead of 5.0). Anything older than 5.0 is not supported.

mentioned ffmpeg version in readme.md file.
