I believe this is fine, just let me remind you of two points (from the
above i guess you know them already):

1) since you are changing demuxer api, you must increase the version
number at the corresponding header.

2) since old demuxers (with different version numbers) won't load
anymore, it would be very nice if you could also update all other
demuxers with your changes. (that is, provide the dummy methods)


that's it. i just hope we can get a gpl'ed dvbsub decoder sometime! :)
