  • HTML5 does not include a dedicated streaming protocol, nor does the iPad/iPhone
  • RTMP streaming can change video quality mid-stream
  • allows for optimal playback quality in the fullscreen and WiFi/3G scenarios
  • if the connection speed drops below the minimum bandwidth needed for the video, playback will be continuously interrupted.
  • has specific server and protocol requirements, which makes it less accessible and adds significant complexity and cost
  • Adaptive HTTP Streaming is a fairly new streaming format
  • Adaptive HTTP Streaming works by storing your videos on the server in small fragment
  • daptive HTTP Streaming leverages standard webservers, it is supported by webhosters and CDNs alike.
  • none of the Adaptive HTTP Streaming implementations work with regular MP4 files.
  • Adaptive HTTP Streaming will likely become the single video streaming method over time
  • live streaming is not possible,
  • o data is downloaded in advance and data a user has seen is immediately discarded.
