[mythtv-users] Mythfrontend failing to display subtitles for some type of file

[Paul Gardiner]

One further discovery: if I demux the orifinal file to produce two 
files, one containing combined video and audio, the other (a .srt file) 
containing just the subtitles, mythfrontent displays the subtitles 
without problem. The logs suggest this mode uses a very different code 
path, so the experiment didn't help track down the cause.

I wonder if, in the failing case - without demuxing, the subtitles are 
being displayed off screen or with opacity 0. Perhaps it's silently 
failing to load a font. The logs show events as each subtitle should be 
displayed.

At the moment I can't think of a way to track this down further.
