I am publishing H264 from Flash 11. I was using FFmpeg to inspect the stream and noticed I am getting duplicate pts/dts time stamps. I edited libavformat/flvdec.c to dump what is pulled from the fly container. Below is a small portion of the log. FMLE does not exhibit this problem, nor does a RTP stream coming out of wowza regardless of the input (FMLE or Flash). What should I look for in the wowza DEBUG log. [log] stream: pts dts. //generally it is not this bad.

You can look at stream pts and dts by adding this Property [https://www.wowza.com/docs/how-to-debug-encoder-multi-bitrate-keyframe-alignment](https://www.wowza.com/docs/how-to-debug-encoder-multi-bitrate-keyframe-alignment) If you are trying to do multi-bitrate with ffmpeg, it has never worked in our tests.
