Well it looks like the patch omits the check for the header completely. The value of have_mp4v2_h is not checked anymore. Does this not break the build if you have the library but not the development headers installed? I guess the build system should check for either mp4v2/mp4v2.h or mp4.h
I do not really understand why this aborts "when loading an mp4 file". It looks like it should already abort at the configure step due to unfulfilled dependencies.
