notfreebeer 3 Posted October 16, 2021 Share Posted October 16, 2021 Hi, apparently I'm not able to switch to another audio track from the Emby app for Tizen (1.1.04). I found this post which is very similar, and I'm wondering if it's still a thing, in particular: Quote @Luke the problem here is that the default track is not the first audio track. chrome has no api to change tracks, so when we direct play, we are relying on it to choose the track marked as default. To resolve this we will have to trigger a transcode when the default track is not the first track. Except this is not in chrome but in Tizen, similarly to that post the media (mkv/h264/eac3) is being direct played and the audio track selection is only modified in the player UI... the audio keeps going with the first track no matter what. Thanks everyone for your support. Link to comment Share on other sites More sharing options...
FrostByte 5024 Posted October 16, 2021 Share Posted October 16, 2021 Could you post your TV model and a screenshot of the media info from the web client for one of the videos you're having problems selecting an alternate audio track? Are you switching tracks before clicking play or during playback? When you try changing the audio track is the popup appearing to switch the audio track coming up and then just not changing anything when clicking play? Or is the selection popup not even appearing? Are you starting from the beginning of the movie, or jumping to a chapter after making your audio change? There is a known problem when doing this.

I can't change it before playing since it's already detected as the default track and showing as the selected track (but in practice the other one is picked when playback starts). During the playback I just try to switch back and forth but nothing happens. 3 hours ago, FrostByte said: When you try changing the audio track is the popup appearing to switch the audio track coming up and then just not changing anything when clicking play? Or is the selection popup not even appearing? You mean the audio track selection dialog? Yeah it does come out, I select the language but the audio is unchanged. Nonetheless, this new track is (in)correctly reported as the current one when I open the audio settings again... 3 hours ago, FrostByte said: Are you starting from the beginning of the movie, or jumping to a chapter after making your audio change?

Luke 36887 Posted October 16, 2021 Share Posted October 16, 2021 Why do you think you can't change it before playing? You can set it to any track you want before playing. Link to comment Share on other sites More sharing options...
notfreebeer 3 Posted October 16, 2021 Author Share Posted October 16, 2021 (edited) Sorry maybe I was not clear enough... I mean, there is nothing to change, the one I want is already selected (i.e. the app succeeds in detecting the default track, but is failing to play it... and additionally is also failing to switch between them).

SamES 880 Posted October 16, 2021 Share Posted October 16, 2021 Can you please post the media info from the bottom of the details page on the server? Please also confirm if playback is DirectPlay, DirectStream or Transcode? Have you tried refreshing the metadata for the file? Link to comment Share on other sites More sharing options...

I confirm DirectPlay. 1 hour ago, SamES said: Have you tried refreshing the metadata for the file? Yes, nothing changes. I should also add, in my PC browser (it reports DirectStream, and remuxing to HLS + transcoding to AAC afaict) everything works as expected, i.e. the default track is actually played by default, and tracks switching during playback actually works.

SamES 880 Posted October 16, 2021 Share Posted October 16, 2021 So this looks like the second audio track is positioned after the internal subtitle stream. That might be causing the issue. Can you please attach a copy of the ffmpeg log from playback as HLS in the browser? Link to comment Share on other sites More sharing options...

SamES 880 Posted October 17, 2021 Share Posted October 17, 2021 I will try and reproduce this, but one question, was the file always like this or did you add the additional audio track somehow? Link to comment Share on other sites More sharing options...

That might be causing the issue. Actually - speaking about the Tizen app in DirectPlay mode - I tried with other medias where subtitles are the last streams in the container or with no subtitles at all, and the issue is the same: only first audio track played (which may happen to be the default one) and in all cases no possibility to switch between tracks. 11 minutes ago, SamES said: was the file always like this or did you add the additional audio track somehow? No, I didn't modify anything of the original file (strictly speaking about me, i don't know about the file creator).

FrostByte 5024 Posted October 17, 2021 Share Posted October 17, 2021 While SamES is looking at it there is something you could do to fix the file so that it's in the normal order. Mkvtoolnix will allow you to easily reorder them using drag and drop (just grab a track and move it up or down). You can also set the appropriate default/forced flags then too if needed. Then just remux. If you have a lot of them it could take awhile, but at least the file should be good no matter what app you're using for playback. Typically, tracks should be grouped together in video/audio/subtitles/chapters order. Then you usually want your default tracks to be the first in each section also as some apps have issues with that. 1 Link to comment Share on other sites More sharing options...
notfreebeer 3 Posted October 17, 2021 Author Share Posted October 17, 2021 Hey @FrostByte thanks! Yes I'm aware that I can reorder the streams, and that would fix the first issue for sure (the desired track selection), still not second one maybe (track switching at playback time)... as you say, it can be a temporary workaround, but not very feasible on the long run and with multiple files. Especially because it would require human inspection or scripting, and would double the space requirements to hold the modified copy if keeping the original is required. Anyway yes, it's sad many apps have issues with ordering or default selection. The internal media player on Tizen is no exception (via dlna or usb stick), but at least I can switch between tracks there. 1 Link to comment Share on other sites More sharing options...

notfreebeer 3 Posted October 18, 2021 Author Share Posted October 18, 2021 Hi @Luke, @SamES since my files are quite large I looked for an equivalent sample video which has the same issue and that anyone can grab. I picked the sample 5 from Matroska test files... must be a good and well-formed demo to use as reference I guess. The original file is mkv with video + default audio + default subtitle + other subtitles + secondary audio + other subtitles. Starting from this I created a second file which is an exact copy, except the default flag removed from the primary audio track and assigned to the secondary one. The results are: the samples are DirectPlay-ed for both of them the first track is used when the playback begins for both of them the played track is unaffected when switching during playback for both of them the played track is unaffected when switching before playback although nothing changes, the player UI is updated according to the selected track similarly to the post above from the other day, everything is ok from the web app, both default selections and track switching (DirectStream/HLS) If you have other things to test I think we can agree on this file as reference.

FrostByte 5024 Posted October 20, 2021 Share Posted October 20, 2021 Do you have the latest firmware for your TV? Sometimes these odd playback issues are firmware related. I'm seeing 1805.4 with a date of Sept 16. Link to comment Share on other sites More sharing options...
