Hi @Alexlp-8657,
Thanks for your patience. Streaming is billed as the combination of streaming services and the quantity of data transferred. When Azure Content Delivery Network is enabled via Media Services portal or API for a streaming endpoint, standard Content Delivery Network pricing applies for all data transferred. Billing is prorated per minute of video processed per stream. Billing starts once the video pipeline processing is started, no matter what the processing status is (running/failed etc.), and stops when the processing is explicitly stopped. So you are paying a price per video being streamed.
Hope that helps. please let us know if you have further questions.
Best,
Grace
