I have problems with subtitles on older webOS 2 tv sets.
External srt is diplayed for a second then disappears. Subtitles embedded in the mkv file cannot be chosen, the first is displayed regardless of settings.
Any other client I tried works fine, including newer LG tv sets, Android phones, a Samsung TV and several web browsers.
(Screenplay application can't display subtitles either, so I think the problem must be webOS version related)
I restarted the emby server from the web interface, then started a movie with an external subtitle. The subtitle displayed for a second, then disappeared. Subtitle size and colour settings were not what I set up previously in user preferences.
The client I started the movie on:
LG 43UF7787-ZA, application version Emby Theater 1.0.20, software version 04.05.85, webOS version 2.2.1-2147 (beehive-biscayne)
My Emby server version is 126.96.36.199, it's running on a Synology DS215+
The user I tried to play the file with is named IRO.
The movie is a H264 mkv with AC3 audio. Full details from the movie page are attached.
According to the stats on the client interface and Emby dashboard the movie were direct played.
I can't see new ffmpeg log files generated on the server if I start the movie on the TV, nor on my Android phone, so can't post them. (If I play from a web browser ffmpeg-directstream files are indeed created)
I attach the embyserver and hardware-detection logs.
If it's any help, the oldest LG set which works fine among the ones I tried is a 55LF652V-ZA, software version 04.06.30, webOS version 2.2.3-169 (beehive-biscayne). It's a slightly newer webOS but still version 2.
