What does this mean?
When you set the streaming setting to Original, it never is supposed to transcode., for OTA, the server does not even see the video stream (tuner sharing off). With TVE, the stream always goes through the server and out to clients. This is what I was told and understand how your software works.
HLS far as I understood, was only used when transcoding is needed, like to web browser. Not used in direct play to a client. So this forces HLS then?
This buffer setting pictured is under the Transcode section, thus only is applicable to remote streaming or web browser playback. You mention this in your statement, however, the 3rd condition, when you enable the debug option? what do you mean, where is that? in the client app? I do not see any option on my Apple TV. (edit: i was not using the test flight version, now i see 4 options under debug.) Can you explain what 'Use HLS Streaming when Efficient" does compared to the others?
Enabling this now results on full moving the live tv pause buffer to the server? Is that what this HLS streaming setting does? If so , that is not really made clear that is what this feature does.
For some servers, like a Pi, having constant read/write to the storage drive could significantly lower performance overall. But for more powerful devices, I would think would surpass the client device in performance perhaps.
I have no low performance/low storage client devices anymore to play around with this feature though.
