Run ./autogen.sh instead of autoconf, so that we don't need to patch

 If an option is wanted, it is easy to add.

It is not exact with rgb blending.

The name might be ill chosen, but duplicated code is worse.

recursive=expand can be too time-consuming (preventing users from exiting vlc)

We do not need to copy here anyway.

This kills a memory copy in most cases (FFMPEG input padding is the same
as VLC block padding, at least on my system).
