[FFmpeg-devel] [PATCH 1/2] avcodec: Add interface to motion estimation

[shen long]

This discussion again hehe. I'm just a user and I don't think a
reunification is possible, I was reading the gentoo forums and it
became a flame war between users, most of them bashing Libav. Though I
like the name "libav" better.

https://forums.gentoo.org/viewtopic-t-1010096.html

The way Libav started, it was clear that it was not a fork, but a
replacement, something meant to put and end to ffmpeg immediately, so
it needed a purely political position. A fork must rename its
applications AND libraries, so both original and deritive works can
coexist peacefully and users can choose what is best for them.
