Server Version#: 1.27.2.5929 Synology NAS 64bit
Player Version#: 7.0.13.7804-2fd4cda44-Plex
Roku app 7.0.13.7804-2fd4cda44-Plex on Roku Ultra model 4660RW, software version 11.0.0 build 4193-46
I have compared this problem to Google Chromecast +GoogleTV 2020, which does not have the problem, nor the Plex Player app on macOS.
This is specific to my Roku Ultra
If I have a two part movie, with part 1 being a .mp4 file and part 2 a .mkv file. The Roku fails to play part 2, after part 1 plays.
If the movie parts are both .mp4 or both .mkv, the problem does not occur.
The Chromecast +GoogleTV 2020 does not have a problem with this, nor does the Plex App for macOS
I have only recently noticed the Roku app failing for this, so I think the problem might have been introduced recently.
Before you say, “just remux the files to be the same type” I will explain that I am doing this purposefully, so that I can retain custom metadata in the .mp4 tags, while preserving the ability to display PGS subtitles in the .mkv file. (The PGS subtitles are not supported in the .mp4 file type). MKV does not support some of the tags that Plex reads from .mp4 files, such as “Long Description”, “Director”, “Screenwriters”, “Studio”, “Genre”, “Release Date”. I keep this metadata in .mp4, so I can preserve metadata, which will automatically be re-read, in case I need to rebuild my database. (If .mp4 supported PGS subtitles, I could just keep one combined .mp4 file, and there would not be a problem like this).
Also, I can’t just toss my Roku, because it supports some apps that the Chromecast doesn’t.
It’s doubtful many others will be encountering this Roku bug, but I hope it can be fixed.
