upcoming ffmpeg transition

[Andreas Cadhalpun]

Hi,

ffmpeg upstream removed some deprecated APIs, so the next release will require
a transition. A large number of reverse dependencies need source code patches.
Most of those are simple changes like renaming functions/macros, but some are
more complex:

building:           30
simple changes:     61
complex changes:    21
----------------------
total:             112

I'll file bug reports for the affected packages with:
User: pkg-multimedia-maintainers at lists.alioth.debian.org
Usertags: ffmpeg2.9

Additionally, there are five unrelated FTBFS bugs among the affected packages:
bino:      #802374
gazebo:    #797809
mrpt:      #803700
ovito:     #803701
pjproject: #793094

It would be good if most of this was fixed, when the next ffmpeg
version gets released.

Best regards,
Andreas
