The FFmpeg code is not complete. It's missing important parts needed at
least to parse timing information (IIRC ffplay shows the subtitles with
completely arbitrary end times that have nothing to do with the correct
timing information). So using the current FFmpeg decoder is not enough
to parse the subtitle packets.

In addition to decoding the subtitles, a rendering implementation is
also needed. The test code I wrote earlier supports vo_vdpau only (since
that was the easiest to implement rendering for). That code would need
some changes before I could publish it even for testing purposes.
