Why isn't shared video showing on live stream?

I started a video via API using

this.api.executeCommand('startShareVideo', 'myvideo.mp4');

The video started fine, but it doesn’t appear on live stream. Why ?

I also tried to use “Share Youtube video” option with a valid youtube video and it didn’t appear on live stream.

Anyone has any idea on how can I sent it to live stream ? Thanks

I found the what was wrong. The problem is that I was trying to access a local asset that wasn’t available to the streaming infrastructure. Thank to everyone who have read this anyhow.
