Speaking notes

I will introduce Spark, a video tool. It is not Apache Spark. That is Spark URL. Click it. major features are Video Preview, In-Player Thumbnails, Watch Next, Smart Auto-Play, Floating player. Video Preview is similar to Animated Thumbnail feature. Watch Next is automatic suggestions for next video. In-Player Thumbnails is similar to Seeking Thumbnail feature. Floating Player is player don't disappears from view when the user scrolls up or down. It is a fantastic player with many other features. Yes, Is is Open source. Look at pricing. You allow advertising, some features are available. If you don't like it, you need money. Personally, I did focus on smooth streaming, no buffering. Because, We also need it. So, How does Spark make smooth streaming and no buffering? Solution is multiple CDNs. Spark algorithm selects the fastest server to deliver first few seconds of the video. And, If one of the server that is streaming the video slows down, Spark algorithm selects another server that can continue streaming the video with no buffering. How about us? Problem of SMR CDN often occurs. If we prepared multiple CDNs and streaming server changing algorithm, Is not it more competitive?

Thanks.
