VLC Web Plugin -- Subtitles -- UDP Stream

dooffas · Postby **dooffas** » 17 Oct 2013 18:39

I am streaming a live TV channel over UDP and to a webpage.
I am using VLCWebPlugin 2.0.8 Twoflower to display the stream.

Code: Select all

        var vlc = document.getElementById("vlc_control");
        var id = vlc.playlist.add("udp://@IPADDRESS", "vlcWindow");
        vlc.playlist.playItem(id);

The video displays and streams fine, without issue. I am trying to use the subtitle track that is included in the stream. I have interrogated the stream and confirmed that a subtitle track is included within the stream.
I have also played the UDP stream in the VLC desktop client and the subtitles work.

Code: Select all

        vlc.subtitle.crount;
        {returns "2"}

        vlc.subtitle.description(0);
        {returns "Disable"}

        vlc.subtitle.description(1);
        {returns "DVB subtitles - [English]"}

Originally I tried setting the subtitle track when loading the VLC object:

Code: Select all

        var vlc = document.getElementById("vlc_control");
        var id = vlc.playlist.add("udp://@IPADDRESS", "vlcWindow");
        vlc.playlist.playItem(id);
        vlc.subtitle.track=1;

This however does not work, so after a lot of searching, it is suggested that a delay is used before the subtitles are initialised.

Code: Select all

        var vlc = document.getElementById("vlc_control");
        var id = vlc.playlist.add("udp://@IPADDRESS", "vlcWindow");
        vlc.playlist.playItem(id);

        function subtitles(){
        vlc.subtitle.track=1;
        console.log("Subtitle track set");
        }

	function start(){
                timeout = setTimeout(subtitles,6000);
        }

        <body onload=start()>

Unfortunately this still does not work. Does anyone have any insight in to this problem?

After further investigation in to this problem it appears to be a bug in version 2.0.8 of the VLC - Mozilla plugin.

Where as the documentation suggests vlc.subtitle.track expects a subtitle track id, it in fact expects the subtitle pid.

I have raised this as a bug: https://trac.videolan.org/vlc/ticket/9715
