cmu-pocketsphinx failing

[mroberts1]

Videogrep is installed, as well as cmu-pocketsphinx (via brew), but when I run videogrep on a video without subtitles the transcription stage fails (see error below). Pocketsphinx appears to be the culprit - I found multiple threads with install problems on recent versions of MacOS.

Tried installing Python 3.9.10 with pyenv but keep getting the same error, including with the latest Python (3.10) on MacOS Monterey.

hi! this looks like an issue with the way videogrep is calling pocketsphinx. I will take a look...

This is now address in the new beta branch (using vosk now instead of pocketsphinx for much better results)
