How can I set the font used by the FLVPlaybackCaptioning component for subtitles? Using the style property of the textarea does nothing, and using a TextFormat makes the text go blank, even though the font had been embedded.

  1. It seems the font, as well as the other properties of the text, are specified in the XML file where the subtitles are read (this is from the documentation):

    <?xml version='1.0' encoding='UTF-8'?>   <tt xml:lang='en' xmlns='http://www.w3.org/2006/04/ttaf1'  xmlns:tts='http://www.w3.org/2006/04/ttaf1#styling'>       <head>           <styling>               <style id='1' tts:textAlign='right'/>               <style id='2' tts:color='transparent'/>               <style id='3' style='2' tts:backgroundColor='white'/>               <style id='4' style='2 3' tts:fontSize='20'/>           </styling>       </head>       <body>            <div xml:lang='en'>               <p begin='00:00:00.50' dur='500ms'>Four score and twenty years ago</p>               <p begin='00:00:02.50'><span tts:fontFamily='monospaceSansSerif,proportionalSerif,TheOther'tts:fontSize='+2'>our forefathers</span> brought forth<br /> on this continent</p>               <p begin='00:00:04.40' dur='10s' style='1'>a <span tts:fontSize='12 px'>new</span> <span tts:fontSize='300%'>nation</span></p>               <p begin='00:00:06.50' dur='3'>conceived in <span tts:fontWeight='bold' tts:color='#ccc333'>liberty</span> <span tts:color='#ccc333'>and dedicated to</span> the proposition</p>               <p begin='00:00:11.50' tts:textAlign='right'>that <span tts:fontStyle='italic'>all</span> men are created equal.</p>      <p begin='15s' style='4'>The end.</p>           </div>           </body>   </tt>

    So maybe the component doesn’t want you overriding those?
