Can you describe the stream settings?

1: Video and Audio codec?

2: Frame Rate

3: Bitrate

4: Keyframe interval(GOP length)

For iOS devices, video should be H264, audio should be ACC. If mp3 then the settings should be 44100Hz, 128kbs.

Profile should be set to “baseline”. A GOP length of 2 seconds is recommended.

You can look at [this chart](http://en.wikipedia.org/wiki/H.264#Levels) to see what frame size to use based on fps.

You can also use the Wowza Transcoder to generate a multi-bitrate set of streams to support different playback clients:

Thank you, I got that my video and audio codec are H264 and acc respectively, frame rate is 25 fps and bit rate is 600 bps

and the profile I set into Main before after I change to base line the green defect has gone.

Many Thanks

Mark
