variable framerate HLS

Wowza Streaming Engine
1

hi,

I am using Wowza-3.5.0 and I am able to do ABR HLS. I have a scenario whose details are given below:

stream 1 : bitrate = 800Kbps framerate = 30 key-frame-interval = 1 sec

stream 2 : bitrate = 400Kbps framerate = 25 key-frame-interval = 1 sec

stream 3 : bitrate = 100Kbps framerate = 15 key-frame-interval = 1 sec

So my query is, with the above scenario ( variable frame-rate across 3 streams and different bitrates ) is it possible to do HLS using wowza.? How does the Key-frame sync happens.?? Does wowza require equal framerate across all input streams for HLS?

Thanks in advance.

As long as the key frames are aligned this should work.

You can check if the key frames are aligned by enabling these properties:
