Nvidia Shield TV: Mis-rendered VOBSUBs (MKV, MPEG2)

This only occurs on the plex app on the nvidia shield; iOS, plex media player on mac (even VLC) are all fine. In the Opera ‘Les Troyens’, at the line ‘the pure air of the fields’ the MKV with VOBSUBS is blurred or rendered incorrectly:

But the file is not corrupted, and plays perfectly in VLC:

Doesn’t have the problem playing via Plex Media Player on the Mac:

Here is a sample of where the problem is:

Could this be a regression? A similar thing was fixed here: https://forums.plex.tv/discussion/comment/1213181/#Comment_1213181 (My post also). @“MovieFan.Plex” did report as fixed back in August 2016:

Sorry, should have been more clear. There is an issue with the subtitle detection of “DVD_Subtitles” versus “vobsub”. This will be fixed in an upcoming update. There is another issue that once this is working, something with the vobsub you provided causes the subs to get rendered incorrectly. So the initial fix to show vobsub subtitles should be available with the update, but you may see some rendering issues which is being looked at and may or may not make it into the same update.

Just wanted to update. The fix was included in 4.29.0 last week. Can you check if it is working for you now or not?

No blurred, mis-rendered VOBSUBS via the iOS app:

So does look like a NVIDIA SHIELD TV issue or maybe a exoplayer issue as it was the last time this was fixed?

I tried playing the file with the plex add-on for kodi, and that too didn’t display the problem that the plex app for android tv is having. Just a quick word from plex to acknowledge this would be most welcome.

Anyone. Maybe @drhill can help?

Hey. Sorry, I had seen this thread earlier and lost track. Can you provide me a short sample with that section of the film? I’m not able to reproduce on my end with the files I have.

I provided one in first post. Only happens on the shield.

Doh, how did I miss that. I was able to recreate the issue. Thanks for the report, I’ll let the devs know.

Any update on this @“MovieFan.Plex”

No update yet.

@“MovieFan.Plex” Any news on this? I didn’t notice a mention in any of the release notes.

@“MovieFan.Plex” Just checked. Still same issue in version 5.8.0.

Still same problem there in 5.10.2

Any news on this @“MovieFan.Plex”

@“MovieFan.Plex” The same issue occurs on a number of other files too:

Issue: VOBSUBS are malformed via the Plex app on the Nvidia shield TV; this issue is NOT present when using Plex for Kodi on the Shield TV or VLC on the Mac.

I reported this back in February, is there any word on a fix? Paging @drhill (who implemented VOBSUB and PGS direct play in MKV)

Sorry, no update.

It’s been 6 months, but I know you’re all busy, so not a problem. Thanks very much for the update.

@“MovieFan.Plex” or @kinoCharlino this is still not fixed. I reported this problem on 12th February. It was acknowledge as a bug too.

Sorry. It’s still listed on our todo list. Just haven’t had time to get to it.

That’s a shame.
