Webcasting needs to be smooth, short delay, clear picture requires high requirements of the CDN acceleration services, as well as the player's Buffer capacity should be well controlled. The cost of the above is quite high, the independent creation of live video is estimated to be mediocre. I recommend using POLYV's live video service. He has the advantage of CDN acceleration of more than 300 nodes across the country, which can solve your troubles in the country to play the low concurrency limit. And you only need a computer connected to the Internet and the camera can be.
