我們知道，Android中MediaPlayer和VedioView能夠播放視頻文件，但是其支持的格式僅限於mp4與3gb。但是視頻格式如此之多，我們不可能只要求播放這兩種，所以就有了下文。
目前比較出名的第三方庫有vitanio與VLC，其中vitamio使用非常簡單，讓開發者直接以library的形式導入工程即可使用，代碼極其簡單；而VLC相比之下就困難的多了。
所以在這裏選擇相對簡單的vitamio第三方庫，而且能夠支持幾乎是全部格式的視頻，非常棒。

官方demo演示效果：![]()
Vitamio支持各種常見的流媒體協議，可以點播或者直播音頻和視頻，例如如下常見協議均能無縫支持：
-
MMS
-
RTSP (RTP, SDP), RTMP
-
HTTP progressive streaming
-
HLS - HTTP live streaming (M3U8)
音頻和視頻格式
Vitamio使用了 FFmpeg 做爲媒體解析器和最主要的解碼器，同時開發了針對不同移動平臺的硬解碼方案，能夠完美支持 H.264/AVC、H.263、MPEG4 等常見的視頻編碼，覆蓋上百種多媒體格式。下表只是一些最常見的視頻格式支持，除特殊標明，全部支持硬件加速：
-
DivX/Xvid
-
WMV (一般只有軟解碼)
-
FLV
-
TS/TP
-
RMVB (只有軟解碼)
-
MKV
-
MOV
-
M4V
-
AVI
-
MP4
-
3GP
一、重寫的MediaPlayer播放效果：![]()
二、重寫的VedioView播放效果![]()
移植到自己的工程之後的效果
一、MediaPlayer演示效果![]()
二、VedioView移植效果![]()
移植過程
一、從官網下載下來的demo打開後是，只有vitamio（庫）和vitamia-sample（使用demo）有用。
二、將官方工程（InitActivity庫+VitamioListActivity例子）導入eclipse，以及建立自己要移植額工程（tieniu_demo）。
三、將InitActivity庫導入我們的工程
四、修改代碼
MainActivity.java
package com.example.vitamia_demo;
