viswanth1038 2 Posted November 24, 2018 Share Posted November 24, 2018 When I start playing a movie, it plays fine(Direct Play) but when i turn on subtitles it starts to transcode the file and video quality is lost. Is there no way of playing without transcoding? Link to comment Share on other sites More sharing options...
Luke 37068 Posted November 24, 2018 Share Posted November 24, 2018 Hi there, some subtitle formats require transcoding. Can we please look at an example? Please attach the information requested in how to report a media playback issue. thanks ! Link to comment Share on other sites More sharing options...

ebr 14913 Posted November 24, 2018 Share Posted November 24, 2018 Hi. The app is falling back to transcoding due to an error trying to direct play. It could be something non-standard in the subtitle format. In any case, if you acquire external srt subs (Emby can do it for you) for these items I believe they will play fine.

viswanth1038 2 Posted November 24, 2018 Author Share Posted November 24, 2018 How can emby get them for me? Link to comment Share on other sites More sharing options...
erikblues 4 Posted November 24, 2018 Share Posted November 24, 2018 (edited) How can emby get them for me? Follow these steps: Access your emby dashboard Select "plugins" on the left menu Open the plugin "catalog" Search for the plugin "OpenSubtitles" (under "metadata" plugins) and install it Restart Emby server Afte you restarted, Access your emby dashboard again select "Library" on the left [For each of your movie/series libraries, do this:] Open the advanced menu (click the 3 dots ... ) Select "Manage Library" Enable "show advanced settings" At the bottom you will find "subtitle downloads" Select the languages you wish to download and enable the settings you need Save and close Select "scheduled tasks" in the left menu Activate "Download missing subtitles" task (click the "play" button right next to it) Wait for subtitles to finish downloading Done PS: If you have lots of movies, it might take a few days untill they all have subtitles. This is to avoid the Emby server spamming the opensubtitles webpage and is normal. Just be patient and in 1-5 days it should be complete. I hope this is clear enough for you to follow. I am new here at the forum so, if you have any questions (or corrections) please let me know. Edited November 24, 2018 by erikblues Link to comment Share on other sites More sharing options...

Gerrit507 24 Posted November 25, 2018 Share Posted November 25, 2018 (edited) I have a similar issue. When I start a movie in the Android TV app and turn on a subtitle it just doesn't appear. I also have pre-configured that it should always show the force subtitles and they do also not appear. The app always shows that the subs are activated. SUBRIP format should be fine. I had this issue with several movies and series in direct play... Edited November 25, 2018 by Gerrit507 Link to comment Share on other sites More sharing options...

Gerrit507 24 Posted November 25, 2018 Share Posted November 25, 2018 Here is an example. I've turned on the eng forced subtitle. According to the log file there are no subs applied as far as I can see. And there is another issue I just found: I wanted to skip forward to a position where I know a subtitle should appear but I'm unable to skip forward. When I skip forward it jumps back to the current position. ffmpeg_sub_log.txt Link to comment Share on other sites More sharing options...
Gerrit507 24 Posted November 26, 2018 Share Posted November 26, 2018 (edited) I've just tried some other files. When a remux is done by emby and subtitles are enabled it doesn't show any subtitles and the skipping is broken. In "true" direct plays or "true" transcodes subtitles work and skipping is working too. Skipping is working in remux but only with all subtitles disabled. I hope this info helps you to narrow it down. Edited November 26, 2018 by Gerrit507 Link to comment Share on other sites More sharing options...

And there is another issue I just found: I wanted to skip forward to a position where I know a subtitle should appear but I'm unable to skip forward. When I skip forward it jumps back to the current position. In this example we are having to convert the audio from TrueHD to plain DD because your system doesn't support the HD audio. There is, however, a plain DD track already. I believe if you selected that one, this issue would go away. I'm pretty sure the reason you aren't seeing subs is because, when we have to remux an item with internal subs, the only way to display those internal subs would be to either burn them in or use a process to extract them to a file and then use that file. If we burn them in, this causes a very heavy load on your server but will display the subs immediately. If, instead, we extract them, they cannot be displayed until this extraction process is complete - which could take a few minutes. Which of these we do is controlled by an option in the playback/transcoding settings in the server. I believe your case was the latter and you just didn't wait long enough for the extraction to complete. The use of external text subs negates all of these problems though.

The use of external text subs negates all of these problems though. 1) You are right with the DD 5.1 stream it's working because it isn't remuxing anymore. The DD 5.1 stream on this movie is german but I usually watch in english and most of them are 7.1... 2) When I first encountered the issue the movie was already running for 30 min when something was spoken in spanish, there the forced subs should appear, and they do on kodi but not in the emby app. I very much doubt that the extraction process was not finished by then... I also don't get it why extracting a subrip subtitle from an mkv would take several minutes. I can do this with mkvtoolnix in a second... Where can I see if there is a subtitle extraction ongoing? Burn-in is no option because emby re-encodes everything in x264 then, that means no HDR for example. Edited November 26, 2018 by Gerrit507 Link to comment Share on other sites More sharing options...
Luke 37068 Posted November 27, 2018 Share Posted November 27, 2018 We don't currently have a way of monitoring the extraction process, if that's what you're asking. Link to comment Share on other sites More sharing options...
Gerrit507 24 Posted November 27, 2018 Share Posted November 27, 2018 Why needs a text based subtitle to be extracted in the first place? I thought this is only for bitmap subtitles. Link to comment Share on other sites More sharing options...
ebr 14913 Posted November 27, 2018 Share Posted November 27, 2018 Why needs a text based subtitle to be extracted in the first place? I thought this is only for bitmap subtitles. Well, if you are transcoding the item and want that subtitle to appear we have two options: 1) Burn it in in a transcode 2) Deliver it as a separate stream to the player The only way we can do 2 is if we have it as a separate stream.

Tanks for the explanation. That means a remux counts as transcode and those two options apply for remuxes too? Just for clarification...

Luke 37068 Posted December 1, 2018 Share Posted December 1, 2018 Remux is not the same thing as a full transcode. Remux could just be a simple container swap. We do not have a way to extract in advance at this time. Thanks. Link to comment Share on other sites More sharing options...
Gerrit507 24 Posted December 2, 2018 Share Posted December 2, 2018 I know what a remux is. To clarify my question: Does the need of either extracting the subtitle or burning it also apply for remuxes? By the way, extracting a srt subtitle takes about 3 minutes on my server when I do it manually with ffmpeg. If after 30 min a subtitle doesn't appear in emby then something isn't working right there. Just saying... Link to comment Share on other sites More sharing options...
Luke 37068 Posted December 2, 2018 Share Posted December 2, 2018 Burning in subtitles only happens during a full video transcode, so this would not be a remux. Sometimes we have the ability to extract the subtitles and avoid the full transcode, that is why we do that whenever possible. So yes, sometimes you could see a remux in combination with a subtitle extraction. 1 Link to comment Share on other sites More sharing options...
