Title: Set _assetWriter.shouldOptimizeForNetworkUse = YES

When the value of this property is YES, the output file will be
written in such a way that playback can start after only a small
amount of the file is downloaded.

I think, 99.9% of use cases of this pod, is to capture video and upload it to s3 and later stream from network.
