I’m not sure at what point this occurred, as I had taken a break from using the Xbox Plex app for a few months, but when I play a video file in Plex, video/audio is not synced/garbled for roughly 5 seconds, before the issue clearing and playback continuing without issues.
The only time this does not occur, is if I have a playlist (whether an actual playlist, or playing all for a season, etc), and then it’ll occur for the first video in the playlist, but not at all for any of the other videos in the playlist.
It occurs in both the old Plex app, and the 2.0 version recently released. This issue did not exist the last time I had used Plex regularly on my Xbox One, which was a few months ago.
It does NOT occur on Plex Web, Plex for Chrome, or Plex for Android (the other ways I use Plex). Server is up to date to the last non-Plex Pass release.
After some experimenting, I also found the garbling for a few seconds does not appear on a file if I started playing it on another platform (ie: my laptop in Chrome), and then resumed that same file on the Xbox One (whether I start back at the beginning or at the point I had stopped watching on another platform).
Also, 5 seconds is the long end. Some files only garble for a second before stabilising.
Hmm diagnosing direct play issues is a little tricky. With direct play we’re just passing the file over to the system video player to decode and play. Any playback issue is likely an issue with the system decoder. If you lower the quality or disable direct playing and direct streaming does the file play back okay? The reason the other platforms might not struggle is because they may be transcoding or their platform player stacks are more resilient to issues in the file.
