Hi there,
Looking at your Output config JSON, I see that you have MUXED the Video and Audio for your CMAF output. What that means is that you have included the Video and Audio under a single output. Currently it looks like this:
CMAF Output Group: |
. -> Output-1:|
. ->Video-Data,
. ->Audio-Data
Per CMAF architecture, this is an incorrect way of designing a CMAF stream. The correct way would be to produce the same Video and Audio parameters, but in their separate outputs. This should look something like this:
CMAF Output Group: |
. -> Output-1:|
. ->Video-Data
. -> Output-2:|
. ->Audio-Data
You may try the following Output JSON instead of the one shared above:

Thank you so much. Let me try this out and update soon.
Thanks, A modification to the baove config, finally worked. But i realised, I was looking for generating fmp4 H265 HLS streams. I am a little confused if CMAF with a different config will be used or Apple HLS .
Is there any documentation I can refer to for this. Apologies for the possibly noob question
