I noticed from the last FFmpeg resync that libavcodec now supports

might pop up in future FFmpeg versions...
I noticed there was a codec id range added for DVD subtitles, and also that
the first ID in that range overlapped with the DVB sub's ID. Can you
give any pointers
how should I adapt the patch to use the API? I'm not familiar with ffmpeg API.
I'm not that familiar with it myself - but it looks like FFmpeg provides
decoders - so your decoder would have to be ported into libavcodec (and
probably then sent off to the ffmpeg people for good measure). The decoder
returns an AVSubtitle struct, which looks like it has a position, size,
timecode and an 8-bit palettised image, which could then get fed through
your display code.
