您好我正在开发应用程序，我需要在Facebook和YouTube上播放实时视频。所有我都知道Facebook和YouTube提供clock-frequency。
现在我需要将public class DBHelper extends SQLiteOpenHelper{
//USER TABLE
public static final String USER_TABLE_NAME = "MyTableTwo";
public static final String USER_COLUMN_USER_ID = "id";
public static final String USER_COLUMN_USER_NAME = "Item_Name";
public static final String USER_COLUMN_USER_ADDRESS = "Weight";
public static final String USER_COLUMN_USER_CREATED_AT = "MRP";
public static final String USER_COLUMN_USER_UPDATED_AT = "BARCODE";
public DBHelper(Context context,
String dbName,
Integer version) {
super(context, dbName, null, version);
}
@Override
public void onCreate(SQLiteDatabase db) {
tableCreateStatements(db);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + USER_TABLE_NAME);
onCreate(db);
}
private void tableCreateStatements(SQLiteDatabase db) {
try {
db.execSQL(
"CREATE TABLE IF NOT EXISTS "
+ USER_TABLE_NAME + "("
+ USER_COLUMN_USER_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ USER_COLUMN_USER_NAME + " VARCHAR(20), "
+ USER_COLUMN_USER_ADDRESS + " VARCHAR(50), "
+ USER_COLUMN_USER_CREATED_AT + " VARCHAR(10) DEFAULT " + getCurrentTimeStamp() + ", "
+ USER_COLUMN_USER_UPDATED_AT + " VARCHAR(10) DEFAULT " + getCurrentTimeStamp() + ")"
);
} catch (SQLException e) {
e.printStackTrace();
}
}
public List<MyTableTwo> getMyItems() {
List<MyTableTwo> mySuperList = new ArrayList<>();
SQLiteDatabase db = this.getReadableDatabase();
String selectQuery = "SELECT * FROM " + USER_TABLE_NAME ;
Cursor c = db.rawQuery(selectQuery, null);
if (c != null) {
c.moveToFirst();
while (c.isAfterLast() == false) {
MyTableTwo myTable = new MyTableTwo();
myTable.itemName = (c.getString(c.getColumnIndex("Item_Name")));
myTable.weight = (c.getString(c.getColumnIndex("Weight")));
myTable.mrp = (c.getString(c.getColumnIndex("MRP")));
myTable.barcod = (c.getString(c.getColumnIndex("BARCODE")));
mySuperList.add(myTable);
c.moveToNext();
}
}
return mySuperList;
}
public Long insertUser(MyTableTwo user) throws Exception {
try {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(USER_COLUMN_USER_NAME, user.itemName);
contentValues.put(USER_COLUMN_USER_ADDRESS, user.barcod);
contentValues.put(USER_COLUMN_USER_CREATED_AT, user.weight);
contentValues.put(USER_COLUMN_USER_UPDATED_AT, user.barcod);
return db.insert(USER_TABLE_NAME, null, contentValues);
} catch (Exception e) {
e.printStackTrace();
throw e;
}
}
private String getCurrentTimeStamp() {
return String.valueOf(System.currentTimeMillis() / 1000);
}
传递给RTMP URL客户端。 WebRTC官方网站说 -
运行AppRTCMobile App AppRTCMobile是一款Android应用程序 通过JNI使用WebRTC Native API（这里记录了JNI包装器）。
。对于JNI，我需要包含NDK，这将使app变得沉重。 webRTC是唯一的方式吗？任何帮助将不胜感激。
答案 0 :(得分：3)
我最近参与了一个项目，我在项目下面整合了相同的要求 -
它是免费的，OpenSource在 GitHub 上有效。您所需要的只是提供您将从Facebook / YouTube获得的RTMP网址。
