SOLVED: Roku app crashes when showing thumbnails

[finicky6457]

I'm using Roku app version 2.2 build 1 and when open Shows, then a specific show, then the Season, the Roku app crashes. It doesn't happen to most channels but i did notice is always happens when viewing This Old House and Ask This Old House on my local PBS station. Other shows on the same channel do not cause it to crash. Seems like something with the thumbnails or metadata is causing it to crash.

Happy to upload any logs that would help.

So this is a live TV channel? Are you viewing the TV guide or are you viewing the recording for the show? Are you able to tell what KIND of image it is using for the show? PNG? JPG? AVIF?

These are recorded shows. I looked in the directory where Jellyfin stores the .ts recordings but there is only the video file and a .NFO metadata file. The Roku app shows thumbnails but I don't see an image file for it.

In the NFO file, either in tvshow.nfo or the NFO for the individual episode, does it provide a file path or URL for the image? Or is it just using the thumbnail from the video itself?

If neither has an image specified, it is probably just an image it pulled from the TS file.

Can you try going into a browser and for the show/season/episode, then refreshing metadata but select "replace all metadata" and check "replace all images".

The .NFO files do not have URLs for the images. I refreshed the metadata and this fixed the crashing problem.

Possibly related, when i tried to play these video files, the Roku app quickly flashed "error during playback" on each of the videos on one show, and the first video on the second show. The rest of the episodes played from the second show.

After refreshing, did those files successfully play? Or are you still having issues? If they still fail, share your full jellyfin server log via pastebin.

After refreshing, the app now lists all of the recorded episodes (it hadn't been able to show them because it crashed). Now I get playback errors when watching some of the episodes (but not all). The first three episodes had the playback error. the other ones played correctly. I played them all and here is the log file:

I also noticed that there were no transcode logs when i played them on the Roku. Also, these episodes play fine in the web browser (and have transcode logs).

What codec are the recordings in? If they are MPEG2, turn off MPEG2 compatibility in your Roku?

[finicky6457]

They are MPEG2. Turning off the MPEG2 support on the Roku seems to have fixed it. Is that the recommended setting?

[TheDreadPirate]

It varies depending on your Roku model. My Roku (4802X) direct plays MPEG2 without issue. I've also seen a bug with the Roku app where, depending on how hardware acceleration is setup, MPEG2 in TS will direct play if you have HWA enabled and it will fail when HWA is disabled.

Remuxing to MP4 should work around the issue, if you have the same issue as that github link.
