I have an interesting issue with Omni Describer. When I first tried it several months ago, it worked like a dream. Now, I cannot even get to the point where the YouTube video is downloaded. It times out. It doesn't matter which vid I try, even short ones. I've swapped out the API key, not that we're even getting to that stage. I've updated the app. It's a shame because it used to be good.
@brian_hartgen that is interesting that yours is timing out. I just tried it with the following youtube video, and mine went threw it just fine.

I have attached an mp3 file showing you that it did work for me.
