Not sure about ffmpeg, but you should definitely try memorising regexp. Casual Search&replace that becomes possible is worth it.

Don't learn the Perl influenced extensions. You just need POSIX EREs (and BREs for some older utilities) which are simple enough to keep in the head.
I'll just leave this here

Many loosely compatible (so, not compatible if we are strict..) implementations are a problem, but awareness and testing helps.
All in all, my life would be miserable if I would not have regexp available in grep/sed/editor/ide/java/python, their usefulness trump any such inconveniences.
in 15 years it never sticks and by the time i need it again i've forgotten it! :D
