Recording live streams with Encoder
If you opt to auto-archive with your encoder (e.g., Adobe Flash Media Live Encoder, OBS), you can save the video content recording to your hard drive. From there, you can then do whatever you want to with that file. For example, you can make it available to your viewers as VOD content, and you can generate revenue by monetizing the VOD content as well.
You can also edit or upload the previously aired content to DaCast, or to another streaming service of your preference (e.g., YouTube).
