Okay, this updated patch plus this 0004 patch for asfdec.c which
depends on 0001 (but is independent of 0002 and 0003) will give
support for asfdec.c and allow formats without parsers to work by
introducing a new virtual function into AVInputFormat for flushing.

There are also some bugfixes detailed in the patch log.

I wasn't sure how to send 0004 since it would change the email subject
and break the thread.
Please let me know if there is a more preferred way.
