 Summary of the bug:

 Hi. I've have some trouble trying to save or play an rtmp stream with
 ffmpeg (lip-sync trouble).
 The same stream plays without any trouble with ffplay!
 Seems that ffmpeg connot manage very well (although ffplay can!) any DTS
 errors (see attached ffprobe report)

 The ffmpeg package is build from the master ffmpeg git (N-74786-g50f2f7a).
 The live stream can be viewed at rtmp://82.208.148.204:1935/live/tvriasi

 I try variour -vsync/async option without any luck.
 Any help will be appreciated.

 best regards,
 laurb
