Early results are looking good for me. I do have a HDHR Extend, so my LiveTV is h.264 in .ts. Scrubbing/Timeshifting/watch from start is working on a recording in process, 45 minutes in, when using a Roku client (direct stream), from a web client (Chrome, transcoding) and PMP on Linux (also direct stream. I know, PMP on Linux is not supported, but it is working!)
It isn’t working from an Android client, but I know this is expected at this point. I’ll be also testing on a longer recording as I can.
Thank you!
Edit: Just for fun, I disabled transcoding on my Extend so it’s mpeg2/.ts. It is still working with the same scenarios with the direct stream. I can’t test direct play on my Roku due to a bug in the current Roku Plex client that crashes the Plex app when trying to direct play live TV (including watch from start I’m finding.) I’ve been told that this will be fixed soon in the Roku Plex app, and I’ll test direct play then.
