Hello,

I am using Wowza Cloud, wuith ULL.

Here is my Config of my iOS Gocoder SDK :

[goCoderBroadcastConfigsetVideoFrameRate:24];

[goCoderBroadcastConfigsetVideoKeyFrameInterval:48];

[goCoderBroadcastConfigsetVideoBitrate:650\*1024];

But I have an issue when i am in a place with bad network, so low bandwith : the playback is slow, video stuck etc…

I see that we can use param to the broadcastConfig to prevent this. I see 3 params :

_setVideoFrameBufferSizeMultiplier_

_setVideoFrameRateLowBandwidthSkipCount_

_setVideoBitrateLowBandwidthScalingFactor_

_I have 2 questions :_

_- Which of theses params must i have to use ? and which value is the best ?_

_- If the bandwitdh go slow and after go back fast, my previous param will be set again ?_

_thanks you in advance 🙂_
