Merge remote-tracking branch 'cus/stable'

* cus/stable:
  ffplay: add support for toggling between multiple video filters with the w key
  ffplay: fix typo in docs
  ffplay: try multiple sample rates if audio open fails
  cmdutils: replace usages of "#ifdef __MINGW32__" with "#ifdef _WIN32" because MSVC only defines _WIN32
  ffplay: fix compilation with Visual Studio
  ffplay: increase AV_SYNC_THRESHOLD_MIN to 0.04
