kevinmd88 20 Posted August 4, 2022 Share Posted August 4, 2022 (edited) Just wanted to know if Emby has this capability. A lot of my videos have subtitles embedded in the file, SRT and ASS are common. During library scans, can Emby server be configured to automatically extract the subtitles from these files and store them alongside the videos, following the expected naming conventions Emby uses? Just as an example case, if I have the following video Movies |-Movie (2000) |-Movie.mkv and Movie.mkv contains embedded subtitles for the English language, metadata flagged as "forced", the following file would be produced Movies |-Movie (2000) |-Movie.mkv |-Movie.eng.forced.srt (note: I'm aware Emby is capable of handling embedded subtitles in playback, I just want to know if they can be extracted as part of the library) Edited August 4, 2022 by kevinmd88 Link to comment Share on other sites More sharing options...

rbjtech 4222 Posted August 4, 2022 Share Posted August 4, 2022 (edited) This subtitle extraction/cleanup functionality is exactly what has been recently added to the MediaInfo plugin. The Plugin is in the catalogue - but I don't believe the subtitle bit has been fully added yet to this version as it's still in testing. @Cheesegeezer@FrostByte Maybe we can add you to the testing team but please be aware this should not be tested on your main library ! This is the function branded as 'SubKiller' - it removes all the unwanted embedded subs and extracts all text based subs as external SRT's. I believe there is some discussion on having the option to removing all the embedded subs altogether (once they have been extracted) but we need to understand the logic on how emby chooses which subs to use. I believe it will use the external first - in which case, I see no reason to remove the embedded ones. Edited August 4, 2022 by rbjtech 2 Link to comment Share on other sites More sharing options...

I believe it will use the external first That’s correct, that’s what I do, no need for me to remove the internals. To ensure it chooses the external first is better to use default tag in external filename, just in case some internal is already set as default, this works perfectly with smart and always modes. But in the case of “Default” mode if there is a default (no forced) external and a default forced internal it chooses the internal. I haven’t tested default forced external vs default forced internal in default mode to confirm priority.

Its in the final phases of testing and i would value you input along with @FrostByte we just need to tweak the outputs now. Link to comment Share on other sites More sharing options...

So any SSA/ASS subs will have styles and positioning removed, I guess - making it useless for general anime. Paul Link to comment Share on other sites More sharing options...

Paul I don't believe so - the formatting for SSA/ASS (and SRT for that matter) is just held in the external text file instead. ffmpeg just copies it as is - but we need to check this. 1 Link to comment Share on other sites More sharing options...

I have very limited experience with using fonts - I'm assuming ffmpeg could extract it, but not sure if externally Emby is setup to use it if specified in the external sub file ? Do fonts works 'today' with emby if embedded in the source file ? - if yes, then we could just recreate this step before hand. Not sure where the font file would be held though. The whole reasoning behind this is to reduce the possibility of transcoding/streaming - so unless the end result is direct play - we have not gained anything by doing this.

Paul Sure I have extracted the subs for my entire Anime library, fonts the same, what I have noticed with the extracted ass files is that the extracted one is shown with tinier fonts than the internal one in emby android tv, not sure other clients, need testing to compare that. 1 Link to comment Share on other sites More sharing options...

Not sure where the font file would be held though. Sure they do. I've just been helping softworkz debug a case in which a particular font triggered a crash in Emby's ffmpeg. To the best of my knowledge, if fonts are not embedded, they need to be installed in the system - and that would therefore be required for external ASS files. It's also fair to say that a considerable proportion of ASS files don't use sophisticated styling, and work well enough with default fonts.

ASS files contain a statement of the video size they are intended for. Sometimes (especially if they've been taken from an SD original and transferred to a BD rip without the correct adjustment) this is incorrect, and maybe font sizes were adjusted instead of correcting the video size. This can give rise to unexpected results in some circumstances. Paul 1 Link to comment Share on other sites More sharing options...
