Hi All,

Does WZAACEncoder only support 1 channel audio data?

I’m using method “audioPCMFrameWasCaptured: bufferList: time: sampleRate:” to encode my audio data, but:

- If my audioBufferList has 1 channel ==\> no problem

- If myAudioBufferList has 2 channel ==\> xcode console always show error “WowzaGoCoderSDK: Audio conversion error; status = -50”.

Any help or advice would be highly appreciated.

Thanks,

---

Hello,

I see this question was addressed in a ticket with Developer Support.

It is noted that the SDK app should be encoding in stereo (2) channels.
