Player for android TV and firetv

[TheDreadPirate]

I don’t have many files with DVD subtitles to test, but if all of them are failing, there might be a problem either on the server or on the client side. As an additional workaround, you can disable subtitles on the server. The AndroidTV client uses the server’s settings, so if you disable subtitles there, they won’t load automatically on the client.

Go to Settings -> Subtitle and set Subtitle mode to None.

Where is this setting?  The subtitle config in the library settings is the only one I know of that applies to all clients.

Also, I've only played PGS subbed content since 0.17 was released. But I'll test some of the DVDSUB content I have when I get home.

On the home screen when you click on your avatar, you'll see the subtitle menu.
   

[TheDreadPirate]

Does that apply to your user across all devices?

[vince954]

I think I had it set that way but will check. If so that would solve my problem. If you like I can share a movie file to test with. But having the ability to default subtitles off would resolve it for me.

I did two separate tests (mp4 container with dvdsub) and they both had the same results. When I leave the subtitle mode to default the subs will load automatically and ATV will request a burn-in and the server will error out causing playback failure. When I set subtitle mode to none, the ATV starts without loading subtitles causing successful playback. ATV is the only non-web-based client I have to test.

I also have a Roku Ultra 4800X to test with.

I will be home in a couple hours and will report back on both the Roku and CCwGTV 4K with DVDSUBs.

@TheDreadPirate

I did additional testing and found that all MP4 files with DVDSUBs failed to play, each showing the same extraction error. These files also did not play in the web client. However, when I tested a DVDSUB file in an MKV container, it played successfully on both ATV and the web client. If you can verify this, it seems to be a bug with the server.

Here's a pull request that notes ATV uses the server settings to enable subtitles by default.

Log playing a MP4 DVDSUB file on the web client.

i can send you a link to get some files to test with. note that i am using the windows versio of the server. not sure if this matters. upon some more testing i can confirm i have the server set up to none on subtitles but the players seem to always deault to on and give the error. as far as i can tell its only the androidtv player that does this, strange.. the workaround i am using is to set a button to select subtitles and then turn it off when you start playing the file... this seems to work for now.

[TheDreadPirate]

You could remux your MP4s into MKVs. No re-encoding required.
