Comment on Is it possible to simultaneously record from microphone and camera?
I have done this, but in my test, I found that shortly after toggling Capture Audio and update the stream, the AVAssetWriter will give me an error getSubtractiveDecodeDuration signalled err=-16364 (kMediaSampleTimingGeneratorError_InvalidTimeStamp) (Decode timestamp is earlier than previous sample's decode timestamp.). This will lead to my output video file unplayable. I have no idea how to fix this.
