Tvheadend transcoding with mutiple subtitle streams

Hi all, I am currently trying to create stream profile to transcoding channels for kodi on my tvbox. The default "matroska" or "pass" streaming profil...

UsePIPE profile and useFFMPEG then do what you need.

Hi,
By "PIPE profile", Do you mean the "MPEG-TS Spawn/built-in" streaming profile? If so, Kodi cannot use this profile, it will report the streaming profile not available, so doesn't look like a solution for my situation.
By my testings, Kodi seems to only support these profiles: htsp, "Transcode/av-lib". As I said before, on my tvbox, Kodi hw acceleration mode is not usable when using htsp profile; and Kodi (maybe not only Kodi, if I view tv recordings recorded with "Transcode/av-lib" profille, using other video player like vlc, mpv, the same "1 subtitle" problem also exists) has "1 subtitle" problem when using "Transcode/av-lib" profile.
Looks like if I want to use Kodi with Tvheadend backend on my tvbox, there are currently no solution for my "only 1 subtitle" problem (at least maybe with the current limitation of Transcode/av-lib" profile)?
I have googled for sometimes now with my problem, still haven't found any solution yet. If anyone have a working solution for situation similar to mine, please kindly let me know.

Pass profile stream all as is,
no one watch same stream with all subtitles in same time.
remove unneeded and stream one you use.

Thanks for the reply. But with the current situation, I will not be able to choose subtitle for different show. Because although the channels have more than 1 subtitle streams, but not all of them will be present in the stream. For example, on channel X although always have a total of 4 subtitle streams, show A maybe only have chinese and english subtitle present, but tamil and malay subtitle stream are blank; Another show B maybe have malay and english subtile present, but chinese and tamil are blank. I think you can get the idea.

With one you need from 4 possible?

I think you can get the idea.

I will get the idea when you tell me witch language for audio and subtitles you need.
Until now complete mess with your explanation.

The main problem here is there seems to be no default non blank subtitle stream for the channels. So with the current situation, I might get a blank subtitle stream for some show.

With language is most important for you?

Ok, Consider this situation, I have several channels each with multiple subtitle streams in it; For the sake to simplify explaination, lets assume that channel "X" has a total of 4 subtitle streams at all times, sometimes some of them will be blank, because:
1. Lets say Show "A" is currently playing, it only has english and chinese subtitles available, but the other 2 are blank(which is the tamil and malay subtitles),
2. Then for another time and another show "B", it only has english and malay subtitles available, but the other 2 are blank(which is the chinese and tamil subtitles),
3. Again, another time and another show "C", it only has malay subtitle available, but the other 3 are blank(which is the chinese ,english and tamil subtitles),
4. Again, another time and another show "D", it only has chinese subtitle available, but the other 3 are blank(which is the malay ,english and tamil subtitles),

...

With all these different shows with different situations. and they don't seems to have a default non blank subtitle stream, I might get a blank subtitle stream for some show when I can only get 1 subtitle (because of the streaming profile). So I really can't make sure which one to choose. Hope my explaination is clear this time.

Well, maybe Chinese subtitle, although It will not always be available.

If not Chinese subtitle then maby in same moment Chinese audio is used

Go in Stream filters and set Chinese subtitle as USE other to remove

Ok, thanks, will try that soon.
I do hope that the "1 subtitle only" limitation for the "Transcode/av-lib" stream profile get resolved soon in the future, as this will make the transcoding function more complete in my opinion.

Go ahead and start improving it, otherwise it won't get resolved.
