Fragment/chunk IDs on HDS and HLS

Hello,

When I publish a live stream to Flash Media Server, it assigns HDS Fragment IDs and HLS chunk numbers based on the RTMP timestamps. The benefit of this is that if I am using multiple bitrates, or redundant media servers, the chunk numbers are guaranteed to stay in sync.

Is it possible to achieve the same thing with Wowza?

Thanks!

calculateChunkIDBasedOnTimecode sounded promising, but on closer inspection, does not appear to do what I need (“It will not sync chunks between servers which I think you are looking for.”).

I gather there is a hook which allows custom configuration of chunk IDs for HLS (see List chunks on an HLS live stream), which might solve this problem for HLS. Is there anything similar for HDS?
