Axis IP Camera -> Wowza 4.1 -> HLS -> JW Player..... Buffering......

Wowza Streaming Engine

I have an Axis IP Camera Q6044 being pulled from Wowza and then pull to the end user via HLS and JW Player. When playing back through JW Player I get lots of spinning wheels every so often. When playing back on VLC, there is no problem. Is there some smoking gun that I am missing? Server resources are plenty.

Do you see in your logs if Wowza is having source connectivity issues? If you are unsure, zip up your conf/ and logs/ (include your .stream file) and send it to support@wowza.com for further review.

Thanks,

in ios playback cupertinoChunkDurationTarget , cupertinoMaxChunkCount , cupertinoPlaylistChunkCount settings are important .Also keyframe interval, and fps of stream is important , recommended keyframe 1 ~ 4 . fps 25-30 as I remember .

What’s your current configuration listed above?

This settings worked for me on axis p1346 ,3 years old model. baseline 3.1 ,keyframe 2 ,fps 30

cupertinoChunkDurationTarget

5000

Integer

cupertinoMaxChunkCount

10

Integer

cupertinoPlaylistChunkCount

5

Integer

cupertinoRepeaterChunkCount

5

Integer

if there is gov settings, set up gov as fps*2 .Can you try like this if problem still occur ?
