We have been on YouTube since February 2011 and did our 1st live stream April 2013. Since then we have covered a number of live events. From Ice Hockey, Baseball, Softball to Memorial Services.
Technology keeps changing and we are able to stream using a good mobile phone and reliable 5G network. At the moment in our experience, the Odido Unlimited (T-Mobile Go-Unlimited) offering is the most reliable in most of the Netherlands.
For Baseball, Softball and Ice Hockey away games, we us an Android phone with the IRL Pro App software. Mobile Pictore-in-Picture (PnP) is achivede using the VDO.ninja project and embedding the additional camera(s) in an iFrame.
For home games or where we have access to power and a wired Internet connection, we use OBS Open Broadcaster Software Studio and a prosumer Panasonic video camera connected through an Algato Cam Link USB capture card. Additional cameras are Neocoolcam USB webcams from AliExpress.
