No offense taken (by me at least) ;-)

I might have confused the past reference to libavcodec with libav too.

Anyway, my point for Wei Gao was that it would be very nice to have more
advanced openCL support for ffmpeg as that will benefit a very wide range
of needs and uses and that there has already been some work done on
integration which he may not be aware of.

Come to think of it it seems the deprecation warning in Debian is probably
being added by the package maintainer. I'm sure that s/he has their own
reason but it does seem a little unnecessary to me. Clearly FFMPEG is
alive and well but the Debian people seem to have made a choice to switch
to libav. Probably that topic should be a separate thread though and it
may just be old news that doesn't need to be rehashed.
