HLS fMP4

Open ReubenM opened this issue 8 years ago • 6 comments

With HLS supporting mp4 fragments instead of ts since sometime last year, do you have any plans to make it possible to write HLS and DASH manifests that reference the same segment chunks?

Currently it's really easy to cut TS fragments from TS input. But since DASH needs mp4 anyway, probably at some point it will make sense to write only mp4. Now there's much other work to do on the module until that.

You might want to keep an eye on the CMAF (ISO/IEC CD 23000-19) spec. That's where this supposed unification of DASH / HLS fragment formats is taking place.

I haven't really been able to determine if it is intended to replace DASH & HLS, or if it is supposed to be an abstraction that is meant to ensure interoperability.

Thanks @ReubenM.

BTW, HLS is now defined in RFC8216 and has a chapter about fMP4.

I think that creating an nginx-cmaf-module would be a killer. Are you interested in it?
