A suggestion about an item to be discussed in the Agenda, We can have a perfect DASH validator (We already have one, but a better one) The existing validator does these I guess we can do these.
and some other mathematical stuff that can validate the accuracy of getting the manifest played as expected, not just validate syntactically. @dsilhavy please add this if you could see some potential need for this in the Industry. If yes, we can enhance this. |

Hi all. I would be interested to introduce S4S (Server Side Segment Selection for Streaming) that is based on a transport level available bandwidth estimation. S4S supports a transparent mode based on self-initializing segments (which works with dash.js out of the box) and a non transparent mode requiring to modify the player in order to supports the protocol (a set of HTTP headers and/or query string parameters. We have modified the dash player for supporting both modes and for reporting accordingly the informations displayed by the UI. |

Topic: Subtitle rendering in LL DASH. Recently, there have been discussions in the W3C Timed Text WG (TTWG) about possible issues with subtitle decoding/rendering in low latency scenarios (LL DASH in particular). The issues were whether subtitles need to be delivered in chunks and whether progressive parsing and rendering of subtitle documents are required. The discussion started with IMSC, but the same scenario applies to WebVTT. For more info on the TTWG discussion see the mailing list thread and the TTWG meeting minutes. It would be good to hear some views from the player/decoder perspective. Is there a problem and what could be the next steps for a solution? |
