I have followed the guide at http://www.wowza.com/forums/content.php?460
I can via the captionLanguages decide what subtitle is the default one, and that works;
But, on the IOS unit, on the subtitles menu, I can select "Off," "Auto" or "Hidden text on unknown" . The last one is the only one that gives text on the device. Same thing happens in Safari in OSX when I load my url http://stream10.sli.se:1935/test/_de.../playlist.m3u8.
<!-- Properties for TimedText -->
My expectation was to select "Auto" on the device to get the Wowza default subtitle, and that the other subtitles available in the ttml file should be presented to the user of the IOS device. Is that simple not the case, or am I doing something wrong?
In this test case; Wowza Streaming Engine 4.01., IOS 7.0.6
