## Description

StageIt is a platform which enables musicians to sell tickets and receive tips to their livestream concerts.

On StageIt's front page, they proudly proclaim: "On StageIt, artists perform live online shows from their laptop that are never recorded or archived. That's right! Every StageIt show is a once-in-a-lifetime experience that's not to be missed."

Well, with your help, I would like to change this. I've been recording concerts my entire life. When a concert ends, I like to leave with a souvenir...a recording of the performance I just witnessed, so that I can relive it again and again.

It's free to setup a StageIt account. Most concerts are "pay what you can", so you can usually buy a ticket for $1, although $10 is the recommended price. StageIt uses "Notes" as currency. 10 Notes = $1.00 USD. When you buy Notes, you must buy a minimum of $5.00, which you can use for concert tickets and/or tips.

Here's the URL from this morning's Michael McDermott concert, although obviously, as per their policy, this stream is no longer available:

https://www.stageit.com/michael_mcdermott/the_american_in_me/84726

I've attached some screenshots of my Developer Tools window. It's very easy to identify the a/v elements. In this case, they are streamed as separate .m4a and .m4v elements. For example:

chunk_1593961228_e1f584b7d3.m4a
chunk_1593961228_e1f584b7d3.m4v

chunk_1593961229_e1f584b7d3.m4a
chunk_1593961229_e1f584b7d3.m4v

chunk_1593961230_b0c4b201c0.m4a
chunk_1593961230_b0c4b201c0.m4v

chunk_1593961231_b0c4b201c0.m4a
chunk_1593961231_b0c4b201c0.m4v

Thanks for your help!
