Hi I have excellent news!
libavsequencer now flawlessly integrates into FFmpeg, just check out my
latest git. Please do a git pull --rebase, Stefano had problems without
using it.
Here are the allmixers.c, configure, common.mak, cmdutils.c, Makefile
and libavsequencer.v part of the BSS to review.
This version compiles perfectly.
