Currently, I’m broadcasting the screen to ULL targets with ReplayKit. Everything is good except audio. I want to broadcast in-app audio as well. I only find a sample on github to use the default WOWZAudioDevice class to capture audio from microphone and I succeed on it. However, it turns off in initialization audio and even when I play the music after that, it does not capture in-app audio. I tried attaching an audio encoder WOWZAACEncoder. In audio capturing event of ReplayKit, I call audioFrameWasCaptured(…) with data from the sample buffer but I could not hear anything when playback.

Is there any sample for custom audio with GoCoderSDK iOS?

Thank you.
