Hi Carlos,

This particular API is badly designed and needs changing. When you create a 
stream it doesn't start sending the stream data, it simply tells the backend 
to start encoding the video to a smaller resolution and bitrate, suitable for 
streaming. You have to call a second API with the returned stream Id to get 
the actual video stream resulting from this.

See https://www.mythtv.org/wiki/Content_Service#GetLiveStream

The video is streamed using HLS which must be supported by the browser to 
work.

I don't think from the sound of it that this API is what you want. If the TV 
and MythBackend are on the same network then you don't need to reencode the 
video, you can just stream it directly using this API:

This is what is used for UPnP which works with most TVs.
