问题 We’re taking in mind the possibility of using a media server in order to build our on-premise media service. We’re only focusing at Video- and Audio-on-Demand use-case. Live stream is out of our scope right now. I mean, we’re need to serve pre-registered videos and audios with a good performance.

The problem here is because the videos are not streaming, mediaPlayer on Android fully downloads video and then displays it and this is really slow as you can guess. I am not a native speaker so reading documents mostly hard to understand for me. Which path should I go? RTSP or HTTP streaming. Any tips how can I achieve my goal?

问题 I've made an app to view vine videos on Android devices. These are basically .mp4 videos being loaded into a VideoView . From the following documentation (http://developer.android.com/guide/appendix/media-formats.html), mp4 video playback is supported on Android version 3+ devices.
