* commit '0ebb523f':
  asfdec: check ff_get_guid() return values during seeking

Conflicts:
	libavformat/asfdec.c

The code that pretends that a truncated index is correct and complete is not merged
as it obviously would cause problems if a really truncated index is encountered
If someone has samples that work better with that hack, please share them / mail me

also the bug this apparently attempts to fix isnt reproducable before this in ffmpeg
