That is exactly what I did today, (that is use ffplay to debug my code).

It turns out that I made a poor assumption to do with the timing, and
the subtitle was only displayed for an insignificant time.  Also I had
the alpha channel backwards!

Anyway thanks for all your help, I will keep on plodding along and
hopefully by the end of next week I will have something that works
properly and is pretty enough for the FFmpeg guys.

I'm just about to test my latest version against Myth, if I have success
in showing the subtitles I will post a newer version of the patch on the
ticket I opened.  This is just for people to test with and I do not
expect it to be included in MythTV before the FFmpeg guys accept it.

Thanks again!
