While not mentioned in RFC 4629, this is required for H.263 in 3GPP TS 26.234. It is in practice required for playback with Android stagefright and on Samsung bada phones. Originally committed as revision 26062 to svn://svn.ffmpeg.org/ffmpeg/trunk

commit ab8610aa176c13b5e25a2d8770df28a14665e169 Author: koorogi <koorogi@9553f0bf-9b14-0410-a0b8-cfaf0461ba5b> Date: Thu Mar 18 23:13:04 2010 +0000 The vflip filter does not need to keep ownership of a picture reference. Avoid creating and releasing useless extra picture references in the start_frame and end_frame callbacks. Originally committed as revision 22596 to svn://svn.ffmpeg.org/ffmpeg/trunk The new reference creation is required when the linesizes are used by the previous filters in the filterchain, for example as in "pad=W:H:X:Y,vflip".

This macro is disabled if --enable-small or --disable-optimizations are set. Currently, this leads to warnings about functions being defined but not used, for functions in header files. By defining av_always_inline as inline or as av_unused, we avoid these warnings. This doesn't make a normal build with --enable-small any larger, since the compiler probably chooses not to inline these functions even if they're marked as inline.
