I'll apply this to reduce the amount of patches you need to resend.

Great. Thanks a lot. It will be a real facilitation for us. We will avoid
constantly checking and updating the ffmpeg version numbers while patchset
generating.
As it comes to all the changes you mentioned and that must be done  before
merging our code to ffmpeg, we'll provide fixes as soon and include them in
the next patchset.
