Hello:
Put it simply: How to automatize a playlist with some ads for continuous streaming, in other words to use OBS with a software like Instaplayot or Marsis Playout
For considering: I think that the whole question behind this thread is to obtain affordable solutions for small creative channels. The solutions does exist, but only big networks can pay that. I have learned IMHO that the content is the most valuable think for the future of small TV channels, but spending thousands of dollars for a software is out of the budget.
If you are working on a affordable solution for linux, believe me, many people out there will support that idea and pay a reasonable price.
Thank you for your interest in asking
