Emby Server 3.0.8500.0 (Windows 10 64-bit) is unable to serve external .srt subtitles to Samsung Tizen JS9000, whereas Serviio is successfully able to do so.
Proper DLNA profile configured for Samsung Tizen TV in Emby and confirmed to be in use. The subtitle profile section contains the below:
<SubtitleProfile format="srt" method="External" didlMode="CaptionInfoEx" />
Wireshark TCP capture for failed Emby external subtitles serving scenario showed the following wrong section:
<CaptionInfoEx d3p1:type="srt" xmlns:d3p1="sec" xmlns="sec">
Wireshark TCP capture for successful Serviio external subtitles serving scenario showed the following correct section:
This issue is tied to the methods in MediaBrowser.Dlna/Didl/DidlBuilder.cs which should be checked.
Looking forward to have this issue fixed..and making Emby The One & Only !
