 Using FFmpeg v3.3.1 and trying to open a stream to an RTMPS URL (Facebook
 with SSL actually) results in a few RTMP packets written to the output
 stream but then libavformat tries to read something in return. The thing
 is Facebook does not returns anything resulting in a connection hanged
 after 5-6 packets.
 I solved this issue with this:

 rtmpproto.c:3220 from:

     ret = ffurl_read(rt->stream, &c, 1);


     //ret = ffurl_read(rt->stream, &c, 1);
     ret = AVERROR(EAGAIN));


 This modification will force to not read anything from the server so the
 connection does not hang. With this fix I can see the RTMPS stream on
 Facebook Live preview and does not affect other RTMP streams.
