rexerm 21 Posted May 7, 2023 Share Posted May 7, 2023 (edited) Streaming Stick 4K+ on an LG C2. Embedded SRT (aka, plain text) subtitles won't show up, but external SRT files are fine. In the attached transcoding logs: --first I played the file with the embedded SRT on the Roku (direct play, did not display subtitles) --second I played the file with the external SRT on the Roku (direct play, displayed fine) --third I played the file with the embedded SRT on the LG Emby app (transcoded, displayed fine) Files I used for testing can be found in here: https://mega.nz/folder/Suw3CBhB#7hkGw18Q0aGqI4Qk29Foyg ffmpeg-transcode-30f908a4-0214-48cb-99f4-31ee602eb6d9_1.txt ffmpeg-transcode-cd1f7ce0-aa33-49ff-a511-70318d7e878a_1.txt embyserver.txt Edited May 7, 2023 by rexerm Link to comment Share on other sites More sharing options...

pwhodges 1531 Posted May 7, 2023 Share Posted May 7, 2023 Your file has both default and forced flags on the embedded subtitle stream. I observed only yesterday subtitles not being played with those settings - removing the forced flag fixed it. It's a pain, as HandBrake currently sets the forced flag as well when you select default.

pwhodges 1531 Posted May 7, 2023 Share Posted May 7, 2023 Server, as all my subtitles get burnt in at present - but I'd have to do more experiments to discount other things before making a real report. Paul Link to comment Share on other sites More sharing options...

Also, if you use "Playback Correction" does the subtitle show up? I actually want the "forced" flag, as that's how I've flagged all of my files that contain subtitles (and I've got the "only forced subtitles" setting set on the server). I did test using mkvtoolnix to remove the "default" flag header entirely from the file and just leave "forced," but no change there. I also tested on the other Roku in the house connected to a cheap 1080p Insignia TV and it is also not display the subtitles. Anything else with the "forced" flag (and "default" flag, for that matter) will play ok... but all those are forced to transcode due to being image-based subs. It's only the embedded SRTs that don't get through. Strangely, I embedded SRTs back in the day as Plex on Roku will only direct play if the SRT is embedded and not external. Unfortunately, I don't have a list of what those files were to un-embed them. Link to comment Share on other sites More sharing options...

speechles 1919 Posted May 7, 2023 Share Posted May 7, 2023 (edited) Without changing anything in your media and leaving both the default and forced flags set your file plays with subtitles for me on my Roku without doing anything. The subtitles automatically show. I went and removed the default flag and created a new remux. That new remux also shows the subtitles Automatically. I cannot make it fail without turning them to None (OFF) they turn off. Turn them back on just fine. The screenshot cannot show the video layer. But you can clearly see the stats for nerds shows direct play and those subtitles are showing on your media. What is the model number of your Roku? Which firmware is running on that Roku? What settings do you have in Emby regarding subtitles for that user? Is yours set similar? 44 minutes ago, rexerm said: Ah, yes, it actually does. Have not used this before -- what does this setting do? The video player will react as if it has encountered a problem and simulate a playback error. The response will try to recover playback in the best means possible. It will also remove the ability for the Roku to perform the "Format Detection" (this will use HLS) and will instead choose the video, audio, and subtitle streams to make available to the Roku (using an M3U8).

pwhodges 1531 Posted May 7, 2023 Share Posted May 7, 2023 (edited) With those exact settings I see the same behaviour on my HiSense Roku TV with firmware 12.

rexerm 21 Posted May 7, 2023 Author Share Posted May 7, 2023 Out of curiosity, I switched the subtitle settings to match speechles' (any / no / checked), but it had no effect (other than manually having to select the embedded track). Link to comment Share on other sites More sharing options...
speechles 1919 Posted May 7, 2023 Share Posted May 7, 2023 (edited) The Emby (cc icon) subtitle selector works with both embedded and external subtitles. The * invokes the Roku built-in subtitle handler. The Roku built-in subtitle handler (using *) only works with embedded. Their built-in subtitle handler be giving us grief on firmware 12 and they (Roku) changed/broke something.. If you press * while the video plays and you use the Roku built-it subtitle handler does it show the subtitle which you can select and when selected can you actually see them on screen?

The * menu does not find any subtitles... but it doesn't find them for ASS / DVD / BD subtitles, either, on other movies. However, this particular file defaults to "Always On" under the Closed Captions section in here, whereas the others default to "Off." Changing this to Off doesn't help, though.

pwhodges 1531 Posted May 7, 2023 Share Posted May 7, 2023 Clicking * just brings up the Roku menu which allows selection of "always on" - which I have enabled; as far as I know the Roku never shows a list of subs to be selected (but I may never have tried when there was more than one...). In this case Emby shows the subtitle as selected, but it doesn't play. Paul Link to comment Share on other sites More sharing options...

Solution ebr 14913 Posted May 11, 2023 Solution Share Posted May 11, 2023 Okay, I've confirmed that removing the "Forced" flag on that track solves the issue. With that flag, the Roku player simply doesn't see the track... Link to comment Share on other sites More sharing options...
