TechSmith fork of mp4v2 needs gcc >= 5:
https://github.com/TechSmith/mp4v2/issues/47
As a result, the following build failure is raised since bump to version
5.0.1 in commit df22a9d6b77d9e245dceb7c8fd3f9d80c8917ca0:
In file included from ./include/mp4v2/mp4v2.h:58:0,
from ./libplatform/platform_posix.h:37,
from ./libplatform/platform.h:24,
from libplatform/impl.h:6:
./include/mp4v2/file.h:336:5: warning: identifier 'nullptr' is a keyword in C++11 [-Wc++0x-compat]
ShouldParseAtomCallback cb = nullptr );
^
While a it, drop first patch which is not needed now that mp4v2 depends
on gcc >= 5

-Subject: [PATCH] src/mp4track.cpp: replace nullptr by NULL
-
-Commit 15ec11166ba9ee7b77631d0d9234522f656cfd66 added code that uses
-nullptr. nullptr is C++11, it will break the build with gcc < 5.
-
-Semantically, NULL and nullptr are different, so should not be mixed.
-In this situaiton, m_File.FindAtom() indeed does not return nullptr,
-but NULL (on error, that is).
-
-Switch back to comparing against NULL.
