Embedded subtitle handling clarification needed

[n3mmr]

When Serviio serves up an MKV container with embedded subtitles, will the renderer see all the embedded subtitle streams??

Are there any problems with "PSG subtitles"??? (I have no knowledge of what a PSG subtitle format is, but supposedly they're BluRay style (????) subtitles, and OPPO BDP105EU can supposedly natively play MKV files with H264 video and PSG subtitles.... )

If the file is not transcoded ot serves the file with subtitles. Otherwise not, as PSG subs are image based.

If serviio needs to just remux a container, without any real transcoding, for a particular device, will all the audio, video and subtitle tracks be included in the container stream served to the renderer?

Or do you have to write some special transcoding entry into the profile for that device for all the streams to be included?

Or will this only work for particular types of subtitles?

The Subtitles support page states in the first line of text;

Subtitles support

Serviio supports delivering external or embedded subtitles to all devices.

Is this true even if the container needs remuxing, but no transcoding??

This is normally the case of delivering then either as external text resource, if the tv supports it, or burned in. Serviio does not mux subtitles tracks in files, as mpegts only supports image based subtitles, afaik.

What if one set Serviio up to remux into a format that does support embedded text based subtitles?

For OPPO BDP-s, MKV containers seem to be the ideal delivery format, using H264 and various subtitle formats including text based.

You always seem to reason as if mpegts is the only format Serviio remuxes to. Am I missing some point here?

mpegts is used because its one of the few containers that can be used for on the fly remuxing. If Serviio remuxed to mkv, it would have to wait until the entire file was written before sending it to the TV.
