ffmpeg stuck at startup; Input/Output error #1052
Description
Hello,
I have stream server using nginx 1.12.0, nginx-rtmp-module 1.1.11 and ffmpeg 3.2.5-1~bpo8+1. When I connect to nginx using OBS everything goes fine, but ffmpeg often stuck at startup, but hardly ever doesn't goes stuck and everything works fine.
My command for ffmpeg:
ffmpeg -i rtmp://127.0.0.1:1935/$1/$STREAM_KEY -vcodec libx264 -vprofile high -preset ultrafast -x264opts keyint=40 -vf scale=640x360 -minrate 600k -maxrate 800k -acodec aac -strict -2 -f flv rtmp://127.0.0.1:1935/hls/"$NICK"_low -vcodec libx264 -vprofile high -preset ultrafast -x264opts keyint=40 -vf scale=858x480 -minrate 900k -maxrate 1200k -acodec aac -strict -2 -f flv rtmp://127.0.0.1:1935/hls/"$NICK"_mid -c copy -f flv rtmp://127.0.0.1:1935/hls/"$NICK"_src
FFmpeg output before it goes stuck

Nginx receive play command, because I can find it in access log.
Situation is same with this very simple command that should ends with error there is needed atleast one output.
ffmpeg -i rtmp://127.0.0.1:1935/$1/$STREAM_KEY
When I kill ffmepg with CTRL+C I get Input/Output error.
There shouldn't be any problem with RTMP stream, because it plays normally in VLC.
In my PC everything worked fine, but in server of my company I get this error.
