[FFmpeg-user] Compile ffmpeg-4.2.2 on macOS with SRT 1.4.1 >>> ERROR: srt >= 1.3.0 not found using pkg-config

[Al-Batin Saltanat]

Hi Jonathan,

thank you so much for your help.
On Superuser I got the  advice to use "brew tap homebrew-ffmpeg/ffmpeg”. I didn’t know about this tap and thought I have to compile it myself.
But your advice is very helpful for coming projects. Thanks.

Best Regards,
Robert
