I suppose one last thing to keep in mind is that transcoding does create multiple versions of your stream for playback on various devices that require different bitrates and resolutions and that is very common approach in streaming. If you are not familiar, that is called adaptive bitrate steaming (ABR).
Today’s viewers are out and about, accessing streams from a variety of devices. Different screens and varying internet speeds make video transcoding and processing essential. But, you may not HAVE to for your use case, I don’t know.
For example. viewers on mobile devices would need a lower bitrate and resolution. So carefully consider whether or not you can get away with no transcoding as far as your viewers.
Did that help?
