Relevant thread:

The last time it was discussed we seemed to agree on the migration,
what we lacked was someone actually doing the thing.

One of the advantage of using git would be to have FFmpeg+libswscale
in a unique repo, currently making the checkout of an old version is

Also we may have some commits which require changes to both libswscale
and FFmpeg, currently this cannot be done with a single atomic commit,
same for having a git branch with committs applied to both repos.

Also even using git-svn some commit needs to be done using SVN, for
example a file renaming.

(many others, Google is your Master...)

No need to add another document.

I cannot but agree, currently my patch on the libavfilter test is
frozen exactly because of that.
