EXT-X-START support, manifest manipulation

Question

Is it possible to set EXT-X-START value somehow, or can we edit manifest so we can insert any unsupported tag at any position?

Thanks

Hello,

I spoke with a member of the MediaLive team and learned MediaLive does not support the EXT-X-START tag. If you would like to suggest it as a feature request, you can do so by using the feedback link in the AWS Console while using MediaLive (1).  Select "Feature Request" from the feedback type dropdown.

Thanks, I just submitted a feature request.

Answer

Hello and thank you for contacting AWS re:Post!

I reviewed your information and have some feedback for you. According to RFC8216 (1) for HTTP live streaming, 4.3.5.2 (2) EXT-X-START is the preferred start point of a playlist, one of the Media or Master Playlist tags.  The tag is listed as optional but has 2 attributes:  TIME-OFFSET is required, while PRECISE is not (if omitted, treated as "no").

I am inquiring with colleagues to get some additional details, but believe this tag is supported in manifests.  I surmise you've done some internet research and are finding limited details as I am.  I'll update the post with more details when/if I can find them!

Thank you!
