New subtitle api

[Luke 42077]

This will be in the next dev build. In one sentence, this means

 

Subtitles without transcoding.

 

Which is obviously a very good thing. The api is very easy to use.

 

First, there is a new property added to MediaStream: IsTextSubtitleStream

 

Then, there are two api endpoints:

 

 

/Videos/{Id}/{MediaSourceId}/Subtitles/{Index}/Stream.srt

/Videos/{Id}/{MediaSourceId}/Subtitles/{Index}/Stream.vtt

 

Any text stream supports this - meaning they can be converted to either srt or vtt, depending on what you need.

 

If resuming or seeking, you can also supply StartPositionTicks.

Nice, does the web client use this? I would like to try it out.

[Luke 42077]

in the dev server yes

Are you planning on expanding the StreamBuilder class to generate this url as a companion to the video url if subtitles are requested? Or should we handle that logic separately?

[Luke 42077]

yes, i will be doing that soon, because subtitle delivery method will affect the decision making of direct stream vs transcode

[darwindeeds 356]

Luke, looks like the subtitle stream has to be a part of the m3u8 playlist for iOS to be able to use it without burning/transcoding. Is it something that is possible?

[Luke 42077]

At some point yea. You'll just have to burn it in for now.

[Luke 42077]

But with direct stream you can still use this.

[darwindeeds 356]

Ok cool. Thanks.

Nothing new, just getting it on github.
