Luke 37054 Posted November 24, 2020 Share Posted November 24, 2020 Hi there, we're working on getting a new release out to the store. Let's see if it still happens once that is available. Thanks. Link to comment Share on other sites More sharing options...

SamES 890 Posted November 25, 2020 Share Posted November 25, 2020 Can you show me what all the audio tracks are for that movie? If the LG TV cannot play an audio track it will automatically play the next compatible track. It does this in such a way that the Emby app does not know about it, so while you you may have selected the first/French track, and that is what Emby believes it is playing, if the track is not supported (ie: TrueHD or DTS) the TV will select the next playable track (ie: AC3/DD5.1 which may be in English) I suspect this is what is happening. But Luke is right, in the next update DTS will be converted to another format (AC3/DD5.1) so this will resolve this problem. 1 Link to comment Share on other sites More sharing options...

nitrup93 15 Posted November 25, 2020 Author Share Posted November 25, 2020 Oh ok, so this is solved on the next release with the desactivation possible of the DTS for transcoding ? Link to comment Share on other sites More sharing options...
SamES 890 Posted November 25, 2020 Share Posted November 25, 2020 Yes, it will convert DTS audio to AC3, but you will most likely find that playback performance will not be acceptable. For 4K content, DirectPlay is really the only way to ensure smooth playback, therefore no TrueHD or DTS tracks. If the file does not already have an alternate track in the right language and format, then your best solution is to manually convert the DTS track to DD5.1 and add it to the file as an additional audio stream. Ideally the first audio stream so that it becomes the default playback item. Link to comment Share on other sites More sharing options...
nitrup93 15 Posted November 25, 2020 Author Share Posted November 25, 2020 (edited) Do you have a link or tutorial to convert the DTS track to DD5.1 and add it to the file as an additional audio stream ?

nitrup93 15 Posted November 26, 2020 Author Share Posted November 26, 2020 I use emby on synology NAS and can't find ffmpeg to follow the tutorial. Link to comment Share on other sites More sharing options...
SamES 890 Posted November 26, 2020 Share Posted November 26, 2020 Have a look in the emby system folder on the server. ffmpeg should be located in there. Quote Go to your emby server system directory and find ffmpeg Then at a command window use the following to ADD an AC3 track and make it the default track :- ffmpeg.exe -i input.mkv -map 0:v -map 0:a:0 -map 0:a -map 0:s? -c:v copy -c:s copy -c:a copy -c:a:0 ac3 -disposition:a:0 default -disposition:a:1 0 output.mkv It copies all the existing tracks (original quality) and just adds an AC3 track, derived from the 1st Audio track. This will work on any mkv file incl 4K - it will not touch the original 'input.mkv' file. Link to comment Share on other sites More sharing options...
Happy2Play 8279 Posted November 26, 2020 Share Posted November 26, 2020 Or you can just get ffmpeg on your system. You are not limited to use ffmpeg that is packed with Emby to do this process. You can even look at something like FFMPEG Batch, but there are many programs that can be used to convert/add additional audio tracks from existing tracks.

nitrup93 15 Posted November 26, 2020 Author Share Posted November 26, 2020 So i used XMediaRecode and easy to use, copy video to no transcode it and convert the DTS audio channel to AC3 5.1. We wait the new version of WebOS for desactivate the DTS and use the automatic transcoding on Emby Link to comment Share on other sites More sharing options...
SamES 890 Posted November 26, 2020 Share Posted November 26, 2020 It is quite probable that even with the automatic conversion in the next version that you will find that performance of on-the-fly conversion of the audio track will be unacceptable for a 4K stream, so eventually you will decide that continuing to add additional tracks manually is preferred. 1 Link to comment Share on other sites More sharing options...
rbjtech 4255 Posted November 27, 2020 Share Posted November 27, 2020 @SamES I'm wondering if this function could easily be added into the Emby 'Convert' function to just add an AC3 or AAC soundtrack to the existing Media ? Presumably the Convert function is just using ffmpeg now do do the video conversions - if so, then I guess the code is simply a matter of passing the file location variables and using a video/sub copy function the same as my CLI version .. ? Maybe something I could add to the suggestions ? 2 Link to comment Share on other sites More sharing options...
