環境:

srs: 2.0release,編譯參數 ./configure --disable-all --with-hls --with-ssl --with-http-server --prefix=/home/longjing/srs-2.0release/trunk/build --with-transcode

ffmpeg: 3.2.2 static build，推流命令 `ffmpeg -i "udp://@225.0.0.4:49668?overrun_nonfatal=1&buffer_size=1000000" -vcodec libx264 -acodec aac -preset ultrafast -strict -2 -r 25 -s 720x576 -vf w3fdif -y -f flv rtmp://10.10.10.188:2935/live/live49668/index`

剛開始推流都很好，時間一久了，就發現播放時視頻沒有了，音頻還在，srs.log顯示:
