Android-播放串流影音( Play RTSP Vedio )( 一 )

(更新日期 : 20150430)
目前有看到幾種方法
1 . Media Player 直接撥放
2 . 利用HttpClient連結
3 . Vitamio

實驗結果
如果直接使用方法 1 :
常常因為硬體廠商有無對軟體矯正，LG目前可行，星星星、$ony目前都會出現Error ( 100 , 0 )


直接說明 Vitamio
他有 MediaPlayer 功能，但是相較之下，Vitamio設計的 MediaPlayer 功能更為強大。
但請注意若App內有包含Vitamio和MediaPlayer，必須明確指向路徑!!!
以下是 Rtsp 範例 :

若程式碼內有 " 請更改為 "

1 . 首先下載 : https://www.vitamio.org/Download/

2 . Sample的內容非常實用

3 . 若無方向，這整理出一個範例

4 . 找下載好的 Vitamio 裡面的Lib

5 . 建立一個新的專案並且匯入上一步的Lib( 專案要在同層比較不會有錯誤 )

6 . activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <SurfaceView
        android:id="@+id/surface"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" />

    <TextView
        android:id="@+id/sub1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerInParent="true" />

</RelativeLayout>

8 . 重點( AndroidManifest.xml ) :
要記得新增頁面

<activity
    android:name="io.vov.vitamio.activity.InitActivity"
    android:configChanges="orientation|screenSize|smallestScreenSize|keyboard|keyboardHidden|navigation"
    android:launchMode="singleTop"
    android:theme="@android:style/Theme.NoTitleBar"
    android:windowSoftInputMode="stateAlwaysHidden" />

9 . 權限

<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

10 . 完成
