[Freeswitch-dev] Compiling mod_av cannot find definitions for enum AVLockOp, AV_LOCK_DESTROY

[Seven Du]

FreeSWITCH support libav up to the ffmpeg version 4.4, version 5.0 and up
removes all depracated stuff, we'd like to support the new version and in
the mean time keep the old version work as long as possible. Maybe you can
join the signalwire office hour and the slack channel to talk more about
this. And new ClueCon is coming.
