From: Zhao Zhili <zhiliz...@tencent.com> The macro is meant to suppress false uninitialized warnings. However, sometimes these 'false uninitialized warnings' are really undefined behavior, and leading to real issue like crash, e.g., ab792634197e.
For false uninitialized warnings, it can be silenced by initialization, and compiler can easily optimize away unnecessary initializations. av_uninit shouldn't be used in any case.
