The bottom line during my testing was that I couldn’t
preview the hybrid stream within Nimble Streamer; I
had to copy the playlist URL and paste it into an email
(or create a bit.ly link) to test it on a Mac or iPhone/
iPad that was compatible the hybrid stream. That’s
not a big deal because you’re going to want to do that
anyway, and because by the time you read this, Nimble
Streamer should add JW Player version 8 to the WMSPanel testing, which reportedly can play the newer
I tested playback on my iPhone 6 upgraded to the
iOS 11. 2. 1, and the video played fine (Figure 11). When
testing on a Mac Pro that was not upgraded to High
Sierra, so therefore couldn’t play HEVC, the HLS
presentation loaded, but froze on the first displayed
frame. The stream also wouldn’t play on Microsoft
Edge, which plays HLS natively.
With the legacy stream, I could test within Nimble
Streamer, and the stream played fine on both the older Macintosh and Microsoft Edge. So Nimble Streamer was able to produce the two sets of streams, but
you’ll be in charge of routing them correctly to the
Step 8: Check Server CPU Utilization
Click Servers from the WMSPanel main menu, and
then select the server, and you’ll see the screen shown
in Figure 12. Obviously, this shows that we had plenty of
overhead on the Amazon instance, so we could either
push more streams or rent a cheaper cloud computer.
So that’s it. Hopefully, by the time you read this we’ll
know how to create a single HLS presentation with
H.264 and HEVC streams that can play in all Apple
HLS endpoints. Check the web version of this article
for any progress on that score.

I couldn’t test the stream inside the WMSPanel because none of the supported players were
compatible with Apple’s newest HLS format.
Here’s the hybrid HEVC/HLS presentation playing on an iPhone 6 updated to iOS 11. 2. 1.
Encoding and creating the two adaptive groups left plenty of resources to spare.
