Streaming Media Development-live video implementation

We will not elaborate on the live broadcasting information here. We should be very familiar with live broadcasting and there are various live broadcasting in our life. How can they achieve it? In fact, we should develop a simple and not simple live broadcasting, you only need two addresses: 1. live video address 2. Player. For live video addresses, we can use a lot of software to connect to them. There are also many open-source players. The most common one is FFMPEG, however, if the development workload of FFmpeg is large, we can use third-party player libraries, such as VLC and vitamio. Here we use the vitamio library.

First, create a project named "live". After the project is established, we need to configure the environment required by vitamio. There are a lot of online environments, so we will not write them out here. After adding the dependency library, add a main interface, here I have added only one editview and button. The configuration is as follows:

 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".Live" >    <EditText        android:id="@+id/live_url"        android:layout_width="match_parent"        android:layout_height="100dp" />    <Button        android:id="@+id/play"        android:layout_width="120dp"        android:layout_height="60dp"        android:layout_below="@id/live_url"        android:layout_centerHorizontal="true"        android:layout_marginTop="100dp"        android:text="Play" >    </Button></RelativeLayout>

Main Interface Class:

package com.jwzhangjie.live;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;public class Live extends Activity {public static final String  DEFAULTPATH = "http://ipadlive.cntv.soooner.com/cctv_p2p_hdcctv6.m3u8";EditText Live_Url;Button PlayBtn;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_live);Live_Url = (EditText)findViewById(R.id.live_url);Live_Url.setText(DEFAULTPATH);PlayBtn = (Button)findViewById(R.id.play);PlayBtn.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {Intent intent = new Intent();intent.setClass(Live.this, JieVideoPlayer.class);String path = Live_Url.getText().toString();if (path == null) {path = DEFAULTPATH;}intent.putExtra("path", path);startActivity(intent);}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {getMenuInflater().inflate(R.menu.live, menu);return true;}}
