When I use this command line to stream to http, it doesn't seem to want to display the subtitles.

vlc -I cli --no-sub-autodetect-file --verbose 3 --network-caching=10000 --file-caching=10000 --sout '#standard{access=http,mux=ts}' --http-host=192.168.6.6 --http-port 8080

Here is the version info of the streaming side.
VLC media player 2.1.6 Rincewind (revision 2.1.6-0-gea01d28)
VLC version 2.1.6 Rincewind (2.1.6-0-gea01d28)

Here is the info from within VLC.

At the > prompt I specficially select the subtitle stream with 'strack 3'

It shows on the AppleTV for TvOS (version 1.0.7, based on 3.0.0-git Vetinari) a selection for the subtitle, but when selected, nothing shows.

This is also true for other versions of VLC player on other devices.

I do get a lot of these.

spudec decoder debug: invalid starting packet (size < 4 or pts <=0)
spudec decoder debug: spu size: 0, i_pts: 4571302412 i_buffer: 2

I made the movie file that I'm playing with Handbrake using the Universal setting and added VobSub subtitles.

Maybe I'm missing a setting or something.

I'm not sure DVD subtitles can get inside TS.

I wondered about that.

What would be my possible options at this point?

Seems like maybe I can somehow pull the embedded subtitles out of the file and then stream it that way?

Thanks for any ideas you might have about that.
