这个直播的视频格式可能用的少,之前遇到了一次,现在想起来记录一下

<1>根据后台给出的m3u8的地址，实现播放,核心代码贴出

try {

String url = "http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8";//测试的m3u8地址

//String url="http://devimages.apple.com/iphone/samples/bipbop/gear1/fileSequence0.ts";

MediaPlayer mPlayer = new MediaPlayer();

mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

mPlayer.setDataSource(url);

mPlayer.prepare(); // might take long! (for buffering, etc)

mPlayer.setDisplay(surfaceHolder); //设置显示视频显示在SurfaceView上 自己写个SurfaceHolder设置进去，不懂的可以上网查下这个如何设置

} catch (IOException e) {

e.printStackTrace();

}

<2>下载m3u8的视频。用浏览器打开m3u8的地址，会发现它是个下载地址，默认会把m3u8文件下载下来，右键以文本方式打开m3u8,会发现是一串有规律的文本文件：

#EXTM3U

#EXT-X-STREAM-INF:PROGRAM-ID=1, BANDWIDTH=200000

gear1/prog_index.m3u8

#EXT-X-STREAM-INF:PROGRAM-ID=1, BANDWIDTH=311111

gear2/prog_index.m3u8

#EXT-X-STREAM-INF:PROGRAM-ID=1, BANDWIDTH=484444

gear3/prog_index.m3u8

#EXT-X-STREAM-INF:PROGRAM-ID=1, BANDWIDTH=737777

gear4/prog_index.m3u8

把此地址放到浏览器中，我们又会得到一个同样名为prog_index.m3u8的文件，内容如下：

#EXTM3U

#EXT-X-TARGETDURATION:10

#EXT-X-MEDIA-SEQUENCE:0

#EXTINF:10, no desc

fileSequence0.ts

#EXTINF:10, no desc

fileSequence1.ts

#EXTINF:10, no desc

fileSequence2.ts

#EXTINF:10, no desc

fileSequence3.ts

#EXTINF:10, no desc

fileSequence4.ts

#EXTINF:10, no desc

省略后半部分

通过网络下载把所有的ts文件都下载下来，我写了个方法，在此贴出:

/**

* 给类提供访问网络的方法

* @author Administrator

*

*/

public final class HttpConnect {

/*import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.impl.client.DefaultHttpClient;*/

/**

* 利用HttpClient获取指定的Url对应的HttpResponse对象

* @param url

* @return

*/

public static HttpResponse getResponseFromUrl(String url){

try {

HttpClient client = new DefaultHttpClient();

HttpGet get = new HttpGet(url);

HttpResponse response = client.execute(get);

if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK){

return response;

}

} catch (Exception e) {

// TODO: handle exception

e.printStackTrace();

}

return null;

}

/**

* 利用HttpClient获取指定Url对应的字符串对象

* @param url

* @return

*/

public static String getStringFromUrl(String url){

try {

StringBuilder result = new StringBuilder();

HttpResponse res = HttpConnect.getResponseFromUrl(url);

if(res != null){

InputStream is = res.getEntity().getContent();

BufferedReader reader = new BufferedReader(new InputStreamReader(is));

String line = "";

while((line = reader.readLine()) != null){

result.append(line);

}

is.close();

return result.toString();

}

} catch (Exception e) {

// TODO: handle exception

}

return null;

}

}

使用:

/**

* 解析m3u8,下载m3u8文件

* @param url 传入m3u8的地址

*/

public static void checkURlBTS(String url) {

List m3u8List = null;//m3u8地址集合

List tsList = null;//ts文件地址集合额

HttpResponse res = HttpConnect.getResponseFromUrl(url);

//HttpResponse res = HttpConnect.getResponseFromUrl(url);

try {

if (res != null) {

m3u8List = new ArrayList<>();

tsList=new ArrayList<>();

InputStream in = res.getEntity().getContent();

BufferedReader reader = new BufferedReader(new InputStreamReader(in));

String line = "";

while ((line = reader.readLine()) != null) {

if (line.startsWith("#")) {

} else if (line.length() > 0 && line.endsWith(".m3u8")) {

String mUpM3u8URL=url.substring(0,url.lastIndexOf("/")+1);

m3u8List.add(mUpM3u8URL+line);

} else if (line.length() > 0 && line.endsWith(".ts")) {//判断该文件是否含有.ts文件

String mUpTSURL=url.substring(0,url.lastIndexOf("/")+1);

tsList.add(mUpTSURL+line);

}

}

in.close();

}

} catch (Exception e) {

e.printStackTrace();

}

if(m3u8List!=null&&m3u8List.size()!=0){

for (int i=0;i

checkURlBTS(m3u8List.get(i));//使用递归方式

}

}else if(tsList.size()!=0){

//下载.ts文件

addLoad(tsList);

}

}

/**

*添加下载的ts文件

*/

public static void addLoad(final List urlList){

//for (int i=0;i

for (int i=0;i<5;i++){

Log.e("get(i)-->",""+urlList.get(i));

load(urlList.get(i));

}

}

/**

* @Desciption: 读取任意文件，并将文件保存到手机SDCard

*/

public static void load(String loadURL) {

String path = loadURL.substring(loadURL.substring(0, loadURL.lastIndexOf("/")).lastIndexOf("/") + 1, loadURL.lastIndexOf("/"));

String fileName = loadURL.substring(loadURL.lastIndexOf("/") + 1, loadURL.length());

OutputStream output = null;

try {

//因ts文件非常之多，下载很缓慢，我们项目是使用了okHttp下载的，但为了方便大家，写了个httpclient下载

URL url = new URL(loadURL);

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

//取得inputStream，并将流中的信息写入SDCard

String SDCard = Environment.getExternalStorageDirectory() + "";

String pathName = SDCard + "/" + path + "/" + fileName;//文件存储路径

File file = new File(pathName);

InputStream input = conn.getInputStream();

if (file.exists()) {

return;

} else {

String dir = SDCard + "/" + path;

new File(dir).mkdir();//新建文件夹

file.createNewFile();//新建文件

output = new FileOutputStream(file);

//读取大文件

byte[] buffer = new byte[4 * 1024];

while (input.read(buffer) != -1) {

output.write(buffer);

}

output.flush();

Log.e("success-->","come in");

}

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

if (output!=null){

output.close();

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

最后播放缓存的m3u8.这个就不贴代码了,播放时,就把本地的m3u8地址替换网络的播放地址就可以了。
