I think the Video Containers might have to be reworked to support it 🤔 There are .srt and other subtitle files out there, but it also would come down to I'd think the support of the LibVLC whenever we'd get it swapped.
Shouldn't libvlc already support ass
and srt
subtitles?
libvlc_video_set_spu
to select the subtitle track in the file

Defiantly something id put my hat into to keep updated on this. Virtually all of my video files are mkv with multiple subtitle tracks and audio tracks to support different languages.
I've looked into this, but it seems that with the current UMP library there's no way to get the subtitles through the API unfortunately. We might need to wait until we upgrade to the official libVLCsharp.
We've added external subtitle import support in 2021.8.29.1240. Embedded subtitles aren't supported yet, as that requires more integration with the video playback, keeping this open for that now.
This unfortunately doesn't work with my use-case. I'm swapping out video and image URLs with Logix. This doesn't work for the subtitles here because Neos appears to convert the subtitles to AnimX on manual import, there's no way of providing a SRT/SSA/ASS subtitle file as a URL to Neos and use this functionality which is what's needed for real dynamic functionality.
I could add a "DynamicSubtitleProvider" component for that purpose, that would do the conversion on the fly from a given aset URL.
That would be perfect Froox, thank you.

This has been added in 2021.9.1.665 now!
DynamicSubtitleProvider doesn't appear to work properly. It doesn't seem to update when I replace the URL with a new one and just continues to serve content from the original URL instead, or nothing if I disconnect everything and reconnect it all. Nothing relevant appears to have been logged regarding this.
EDIT: Jeana noticed that resetting the Text field target (selected in the screenshot) seems to get it working again, at least until something breaks it again.
Should be fixed in 2021.9.3.1281 now.
Would it ever be possible to get support for subtitles in a livestream?
I'm not sure how subtitles are normally included with streams so I don't really know what the underlying technical aspects of it are, but it would be nice to be able to use that to encode information through a stream and parse it out in neos.
Also thanks a lot for adding subtitle support, it is very very appreciated.
That should be done implicitly with the support for embedded subtitles from the video player. VLC should decode any subtitles from a video stream if they're part of it.
And no problem, glad they help!

Sorry I think I may be a little confused on what your reply here meant, does this mean that it is currently possible, or that it can be made possible in the future?
Just add to this request, but still in scope of the original ask, please can you also provide EIA-608/CTA-708 support using libVLC for embedded closed captions found within the video stream data.
An example of this is the sample video found at https://sampleplatform.ccextractor.org/sample/4
in a static file in VLC you should be able to see it appear like this:-
STREAM TEST
Using https://github.com/ratwithacompiler/OBS-captions-plugin I am able to encode closed caption data in OBS on to an RTSP stream hosted on VRCDN, which then appears on VLC as a sub track option:-
Additionally this is also true for Twitch streams. More and more users are now using closed captions for including less able viewers. e.g. https://critrole.com/live-closed-captions-on-twitch/
I would love youtube subtitle support. As someone who sometimes has trouble hearing, i would love to see this added in some way.
It would be really nice to be able to use subtitles on videos in some way, potentially with subtitles included in video files or an external subtitle file?
Not going into specifics as I don't really know what would go into implementing this. There have been attempts to implement this through logix but it is typically quite heavy and can be difficult to set up quickly for each video.
