[FFmpeg-devel] [PATCH 00/22] Deprecate av_uninit

[Zhao Zhili]

From: Zhao Zhili <zhilizhao at 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.

Zhao Zhili (22):
  avfilter/af_aecho: Remove use of av_uninit
  avfilter/af_compand: Remove use of av_uninit
