Skip repeated messages, this requires the user app to use av_log() instead of
(f)printf as the 2 would otherwise interfere and lead to
"Last message repeated x times" messages below (f)printf messages with some
bad luck.
Also to receive the last, "last repeated" line if any, the user app must
call av_log(NULL, AV_LOG_QUIET, "%s", ""); at the end
