Thanks for testing it. :)

The altivec optimizations on powerpc are still disabled, but I don't think
this should delay the transition. I intend to fix this one way or another
before stretch is released anyway.


It seems that you have now reimplemented the flavors logic in the ffmpeg
package. Nice.

The only thing that I spotted so far is the issue with "libavcodec-extra".


I've put my transition plan on the wiki [1].

1:
https://wiki.debian.org/Debate/libav-provider/ffmpeg#How_Debian_should_switch_to_FFmpeg


I'm not sure if I understand that wiki correctly, but it seems to be that
you plan on keep on using the package names "libavXXX-ffmpegNN". That seems
unnecessary to me, why wouldn't you want to co stright to libavXXXNN?

I guess the reason is because that matches the actual soname, that is,
libavcodec is currently installed with the SONAME "libavcodec-ffmpeg.so".
This is to ensure co-installability with "libav", but do we really need to
keep this? I think everyone is rather in favor of not having to have both
around.

Unless there is a good reason (such as making the transition significantly
easier, I'd rather avoid those names.

Best,
Reinhard
