I tried it in Linux as well and it ""crashed"" with unhandled SIGPIPE. '''How to reproduce:''' - everything running on windows 7 Professional 64 bit with SP1 - for the test I used Adobe flash server, dacast, wowza, ustream, livestream, showcaster - start streaming with ffmpeg (or use software which utilize the ffmpeg's set of libraries). - unplugg the ethernet cable (e.g. simulate connection drop). - in few moments I have crash (no special info is given except : unhandled exception at
(avformat-54.dll) : Access violation writting location ...) '''callstack has only 1 entry (rest is just some addresses) : avformat-54.dll!avformat_get_riff_audio_tags()''' ''what I think it's going on is, that part of the ffmpeg is trying to send data (RTMP Send) but it does not handled WSAECONNABORTED WinSock Error properly (10053), so it keeps writing to something that is not a valid socket anymore.''
