[FFmpeg-devel] [PATCH 3/5] Renamed reinterlace to tinterlace

[Vasile Toncu]

Hello,

Still Baptiste Coudurier and Michael Zucchi could not be reached, however
since the old GPL tinterlace was replaced with a new LGPL implementation
aren't we on the second course of action recommended by Nicolas George? And
by that means can we change the license of this implementation without the
approval of the original contributors whose code was removed?
Maybe someone else can have a look at the new implementation and provide
the necessary feedback in order to merge this patch and unblock the
development of the patches with new functionalities.

Thank you.
Best regards.
