aacparse progress ? ADTS to raw and vice versa

[Peter Maersk-Moller]

Hi Tim-Philipp.

Thanks for the prompt answer. Looks promising. Looking forward to test. If
I read it right, the code is already in the git-master for plugins-bad?
Will it be in 1.1.4 also or 1.1.5? Is there a plan for which stable version
it will be in. Tried to find the answer to that in the many messages, but
failed.

BTW on the page http://gstreamer.freedesktop.org/modules/ the links to
version 1.1.4 all have a %0A in the end of the link rendering them unusable
without a manual editing. Not a big problem, just an annoyance though.

Best regards
Peter
