Here is the process in My application.
- Mic -> AVCaptureOutput -> Audio(PCM) -> Audio Encoder -> AAC Packet (Encoded)
- Camera -> AVCaptureOutput -> Image -> Video Encoder -> H.264 Video Packet.(Encoded)
So, My App is Movie Encoder.
Crash is happened when camera is switched. (Front Camera <-> Back Camera)
Crash line is AudioConverterFillComplexBuffer.
maybe NativeInt16ToFloat32Scaled_ARM..
what does that mean??? why???
