MediaPlayer：在包android.media中。
VideoView：在包android.widget中，direct subclass of the Android SurfaceView（具体介绍请参考书）。
pixels, resolution, aspect ratios, color depth, alpha channels, pixel blending, image compositing, and even data footprint optimization（类似于图片的概念）。
计算影片大小：每帧的大小＊帧率＊时间
Internet 2.0 IP infrastructure is 1536 kbits/second (1.5 MBPS, or megabits per second)。
A faster data pipe is at least 2048 kbits/s, or 2 mbits/s or 2 MBPS, and video compressed at this higher bit rate exhibits a higher visual quality level. More modern 4G networks claim to be between 3 and 6 mbits/s（3G networks deliver between 600 kbits/s and 1.5 mbits/s, so, on average, these will be 1.5 mbits/s and classified as a medium data pipe）。
DPI：density pixel imagery
For digital video, this also includes different target bit rates, so that you can try to fit all of the different device screen densities and the different processing power capabilities of single-core through quad-core CPU product offerings。
