Comment:

 I updated ffmpeg with the last version 3.2-1.
 I send the same command used for the version 2.8.8, but the behavior is
 different.
 With the version 2.8.8. i can view via RTMP player the RTMP output and the
 video is late about 5 sec on the audio.
 With the version 3.2-1 i can not view via RTMP player the RTMP output (is
 always in initialization state) but in the ffmpeg output log  i can see
 new warnings not showed by old ffmpeg version, but no error.

 What is the problem?

 Output log:
