Symbol not found: _av_codec_iterate

Having trouble getting av to work. I have ffmpeg 4.1.2 installed via homebrew and no errors on pip install av==6.1.2. However, I get the following errors below when trying to use av in Home Assistant. Any ideas what I should do to resolve the missing symbol issue?

Exception in thread stream_worker:

It looks like you have built PyAV against modern ffmpeg libraries but are attempting to run it against an older library version. Most likely your "new" ffmpeg libraries (libav*) are in a location not picked up by the dynamic linker so you will need to set DYLD_LIBRARY_PATH to help it find them.
