Research direction

Start with the parsed-output documentation and compare the expected dateTimeObject with the m3u8-parser parse-stream.js reference linked in the issue. Then trace how live and VOD MPD timing data is parsed, including timescale and presentation timing, and verify that the relevant absolute start-time information is exposed in the parsed output.

Description

Hi,

Thanks for creating such an awesome parser! I'm currently migrating a service that parses manifests to use mpd instead of m3u8 manifests. I am trying to find our when the stream's absolute start time is. Similar to the X-PROGRAM-DATE-TIME of HLS.

Looking at the Docs' parsed output, it looks like there should be a dateTimeObject. In the m3u8 parser, this object definitely exists, and I can see in the code that it gets populated.

I am parsing both Live and Vod mpd manifests but this value never gets populated - and I can't see anywhere in the code where it gets set.

Looking at some Shaka player documentation, I've been able to manually calculate the startTime of my stream as seen here. However, I can't see the variables exposed anywhere, such as timescale etc.

Hopefully I'm missing something obvious, pretty new to all this.

Thanks.
