ffmpeg - upload video stream and audio stream on iOS -

Here are the requirements: People record videos through my app and upload the stream to our website, you know Are like a live show

When they are recording, the network gets spoiled, then record audio instead of video. And when the viewers see, the video comes first, audio with a still image comes in a certain time.

How should I do this? Thank you.

I got it after thinking, so I will answer by my own self.

If you want to record video and audio separately, use a lower level library to handle it. Then upload it and you can get the speed of upload, when the speed decreases, you can stop the video upload process.
