android 播放视频代码
android 播放视频播放视频的两种方式：使用VideoView播放视频（方便，推荐）使用MediaPlayer和SurfaceView播放视频（早期的方式）第一种方式：使用VideoView播放视频的步骤如下：在界面布局文件中定义VideoView组件，或在程序中创建VideoView组建调用VideoView的如下两个方法加载指定视频setVideoPath(String paht)：加载path文件所代表的视频setVideoURI(URI uri):加载uri所对应的视频调用VideoVIew的start(),stop(),pause()方法来控制视频播放MediaContraller类与VideoView一起结合使用的还有一个MediaContraller类，它的作用时提供一个友好的图形控制界面，通过该控制界面来控制视频的播放，快进键，暂停键，后退键以及播放进度条都是该类提供例子代码：xml布局：?<!--?xml version="1.0"encoding="utf-8"?-->1<linearlayout2 3 4 5 xmlns:android="/apk/res/android "android:ori entation="vertical"android:layout_width="match_parent"android:layout_height="match_parent"><!-- 定义VideoView 播放视频 --><videoviewandroid:id="@+id/video"android:layout_width="match_parent"android:lay out_height="match_parent"></videoview></linearlayout>Activity ： ?1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 importjava.io.File;importandroid.app.Activity;importandroid.graphics.PixelFormat;importandroid.os.Bundle;importandroid.widget.MediaController;importandroid.widget.VideoView;publicclassVedioViewTestextendsActivity {VideoView videoView;MediaController mController;@OverridepublicvoidonCreate(Bundle savedInstanceState) {16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 super.onCreate(savedInstanceState);getWindow().setFormat(PixelFormat.TRANSLUCENT);setContentView(yout.main);// 获取界面上VideoView 组件videoView = (VideoView) findViewById(R.id.video);// 创建MediaController 对象mController =newMediaController(this);File video =newFile("/mnt/sdcard/movie.mp4");if(video.exists()) {videoView.setVideoPath(video.getAbsolutePath());//① // 设置videoView 与mController 建立关联videoView.setMediaController(mControl ler);//② // 设置mController 与videoView 建立关联mController.setMediaPlayer(videoView);//③// 让VideoView 获取焦点videoView.requestFocus();}}}第二种方式：使用MediaPlayer 播放视频的步骤如下：创建MediaPlayer 对象，并让它加载指定的视频文件在界面布局文件中定义SurfaceView 组件，或在程序中创建SurfaceView 组件，并为SurfaceView 的SurfaceView 的SurfaceHolder 增加Callback 监听器调用 MediaPlayer 对象的setPisplay(SurfaceHolder sh):将所播放的视频图像输出到指定的SurfaceView 组件调用MediaPlayer 对象的start(),stop(),和pause()方法来控制视频的播放例子代码：xml 布局： ?1234 56 78 9<!--?xml version="1.0"encoding="utf-8"?--><relativelayoutxmlns:android="/apk/res/android "android:ori entation="vertical"android:layout_width="match_parent"android:layout_height="match_parent"><surfaceview android:id="@+id/surfaceView"android:layout_width="match_parent"andro id:layout_height="360dp"> <linearlayout android:orientation="horizontal"android:layout_width="match_parent"an droid:layout_height="wrap_content"android:layout_alignparentbottom="t rue"android:gravity="center_horizontal"><imagebuttonandroid:id="@+id/play"android:layout_width="wrap_content"android:layo ut_height="wrap_content"android:src="@drawable/play"><imagebuttonandroid:id="@+id/pause"android:layout_width="wrap_content"android:lay out_height="wrap_content"android:src="@drawable/pause"> <imagebuttonandroid:id="@+id/stop"android:layout_width="wrap_content"android:layo ut_height="wrap_content"android:src="@drawable/stop"></imagebutton></imagebutton></imagebutton></linearlayout></surfaceview></relativelayout>Activity ：?1 2 3 4 5 6 7 8 910111213141516171819202122 importjava.io.IOException;importandroid.app.Activity;importandroid.media.AudioManager;importandroid.media.MediaPlayer;importandroid.os.Bundle;importandroid.util.DisplayMetrics;

Android开发—SeeJoPlayer视频播放器源码解析
2020.03.27 v1.2.0 beta版：更新说明：一、完美支持android1.五、android1.六、android2.0、android2.0一、android2.1平台；2、完美支持320×480、480×800、480×854等各类分辨率（自适应屏幕分辨率）；3、支持在线音视频播放，支持URL input和从浏览器调用SeeJoPlayer播放器播放在线音视频；4、自动转为横屏播放，为用户提供更好的观看体验；5、修改了没有SD卡程序出错的Bug；6、美化了视频播放列表和操作说明的界面。
第一部份：功能介绍SeeJoPlayer的优势要紧在相对还算美观的界面和便利的交互操作上。
先说操作吧，它支持：一、全屏切换: 双击屏幕二、播放/暂停: 长按屏幕3、静音/恢复: 长按音量按钮4、播放列表: 操纵面板最右边的按钮(暂不支持编辑功能)五、音量调剂: 单击音量按钮，在弹出的音量显示区域触摸改变音量这些操作和PC上的播放器较为类似，希望大伙儿能用得适应。
至于界面的话，多说无益，直接上图吧：第二部份：源码解析一、VideoView与视频比例缩放：咱们能够很方便的取得VideoView的源代码，最简单的方式是直接在上找“.java”。
因此重写VideoView的进程其实只是在原先的基础上进行一些修改罢了，并非一个很麻烦的工作。
什么缘故Android自带的VideoView会维持视频的长宽比而不能让咱们很方便的自概念比例呢？我猜想可能Google 做Android也是一个很仓促的工程，许多代码并无考虑得太成熟。
VideoView的源码中有如此一段代码：1 @Override2 3 4 5 6 7 8 9101112131415161718192021222324252627protectedvoid onMeasure(int widthMeasureSpec, int heightMeasureSpec){//Log.i("@@@@", "onMeasure");int width = getDefaultSize(mVideoWidth, widthMeasureSpec);int height = getDefaultSize(mVideoHeight, heightMeasureSpec);if(mVideoWidth >0&& mVideoHeight >0){if( mVideoWidth * height > width * mVideoHeight ){//Log.i("@@@", "image too tall, correcting");height = width * mVideoHeight / mVideoWidth;}elseif( mVideoWidth * height < width * mVideoHeight ){//Log.i("@@@", "image too wide, correcting");width = height * mVideoWidth / mVideoHeight;}else{//Log.i("@@@", "aspect ratio is correct: " +//width+"/"+height+"="+//mVideoWidth+"/"+mVideoHeight);}}//Log.i("@@@@@@@@@@", "setting size: " + width + 'x' + height); setMeasuredDimension(width, height);}这确实是什么缘故长宽比不能改变的缘故了。
Android移动应用开发案例教程(模块五 实现视频播放)
}
思路： 在GestureDetector中监听onScroll()，判断手势按下点在屏幕的左侧还是右侧，如果 <screenWidth/2说明在左测按下；记录用户移动手指的距离；根据屏幕的总宽度、总音量 和滑动的距离计算声音应该改变的多少；音量改变后的值mvol+delta、音量最大值 maxVolume、音量最小值0做比较，最后取三者之一voice；将声音SeekBar调整到合适的 位置，将音量调整为voice。
核心代码：
public boolean onDoubleTap(MotionEvent e) { if(FULLSCREEN){ portrait(); FULLSCREEN=false; } else{ landscape(); FULLSCREEN=true; } return super.onDoubleTap(e);
this, new GestureDetector.OnGestureListener() {
public void onLongPress(MotionEvent e) { playAndPause();
} );
思路： 为VideoView控件注册手势监听onTouchListener； 再自定义手势监听GestureDetector类的对象，监听onLongPress()，调用视频播放/暂停的 方法； 在onTouchListener中编写手势事件监听转移detector.onTouchEvent(event)。
android编程调用mediaplayer播放器
mediaplayer的生命周期.1. 当mediaplayer被new出来的时候处于idle状态.（空闲状态）mediaPlayer.reset()之前:可以设置错误的监听器.2. setDataSource() 设置数据源. 初始化完毕.3. prepare() 准备开始播放视频或者音频.HDprepareAsync() 异步准备.4. start() 开始播放介绍：这款播放器是基于FMpeg音视频解码库的Vitamio框架和系统的MediaPlayer结合的方式开发的，支持flv、rmvb、mkv、mov、avi、mp4等多种视频格式，mp3、ogg、wma、mid、m4a等多种音频格式，实现了网络视频和本地视频播放，网络音频和本地音频的播放等功能。
技术：软解码和硬解码的使用，json解析服务端数据，采用Popuwindow显示播放控制器播放流程：视频播放器（网络视频，本地视频），音频播放器（网络音频，本地音频）Andoid默认支持视频格式是：mp4,3gp,wmvAndoid默认支持音频格式是：mp3,ogg播放原则：先用系统播放器去播放，当系统播放器播放出错的时候，切换到Vitamio播放器；我已经知道系统播放器播放不了的，直接用Vitamio播放器(支持在线视频，可以从Youku，或酷六客户端调用我们的播放器进来播放)用到了getIntent().getData(); 这个负责得到Url，当然还有单独的播放方法根据这URL地址去播放，但别忘了要功能清单文件里注明<data android:mimeType="video/*" android:scheme="http"/>网络视频<data android:mimeType="video/*" android:scheme="file"/>本地视频<data android:mimeType="audio/*" android:scheme="http"/>网络音频<data android:mimeType="audio/*" android:scheme="file"/>本地音频界面：加载控制视频界面的是一个PopupWindow,作为一种用户提醒而且其开销也比activity 要小，实现了播放，暂停，上一个（后退），下一个（判断一下是否是文件列表，如果是就播放下一个视频否则就快进），声音控制（0-15），自定义一个类控制PopupWindow显示和隐藏的，设置6秒隐藏，用到了handlerMessage消息机制，做了一个方法，6s中之后发一个消息，调用隐藏控制面板的方法硬解码和软解码的大概原理：硬解码：所谓的硬解码就是用系统的接口实现的播放器，那么就可以叫做用硬解码。

Android视频播放器（二）：使用MediaPlayer播放视频
Android视频播放器（⼆）：使⽤MediaPlayer播放视频在我们讲了⼀下如何使⽤VideoView播放视频，了解了基本的播放器的⼀些知识和内容。
也知道VideoView内部封装的就是MediaPlayer，本⽂就介绍如何使⽤MediaPlayer播放视频。
⼀、简介MediaPlayer是Android中的⼀个多媒体播放类，其提供的API能满⾜简单的⼤部分⾳视频的播放需求。
下⾯简单介绍⼀下MediaPlayer：MediaPlayer是使⽤Surface进⾏视频的展⽰的。
MediaPlayer只⽀持mp4、avi、3gp格式的视频，⽀持格式相对单⼀。
MediaPlayer可以播放⽹络视频，⽀持的⽹络视频的协议为：Http协议和RTSP协议两种。
⼆、MediaPlayer 使⽤⽅法MediaPlayer 的提供的⽅法如下：void setDataSource(String path) ：通过⼀个具体的路径来设置MediaPlayer的数据源，path可以是本地的⼀个路径，也可以是⼀个⽹络路径void setDataSource(Context context, Uri uri)：通过给定的Uri来设置MediaPlayer的数据源，这⾥的Uri可以是⽹络路径或是⼀个ContentProvider的Uri。
void setDataSource(MediaDataSource dataSource) ：通过提供的MediaDataSource来设置数据源void setDataSource(FileDescriptor fd)：通过⽂件描述符FileDescriptor来设置数据源int getCurrentPosition() ：获取当前播放的位置int getAudioSessionId() ：返回⾳频的session IDint getDuration() ：得到⽂件的时间TrackInfo[] getTrackInfo() ：返回⼀个track信息的数组boolean isLooping ()：是否循环播放boolean isPlaying()：是否正在播放void pause () ：暂停void start () ：开始void stop () ：停⽌void prepare()：同步的⽅式装载流媒体⽂件。
Android本地视频播放器开发--SDL编译
Android本地视频播放器开发--SDL编译其实1.3以后的版本就添加了android的支持，所以下载完源码后，在SDL目录下创建一个jni的目录，然后将原先SDL目录下面的文件以及文件夹都拷贝到jni目录下面，在jni目录下面我们会看见一个android.mk的文件,这就是官方给我们编写的编译文件，由于手机基本上都是使用的arm编译器，所以我在里面添加了LOCAL_ARM_MODE=arm，模块的编译使用arm编译器来编译，具体的内容如下:[cpp]

android视频播放器-源码
本文讲的是“android 视频播放器”，并附有播放器源代码1．开发环境：eclipse3.6ADT-0.9.7AVD1.62．程序运行效果A．启动AVD(虚拟设备)在应用程序界面主界面，我们可以看到“艾文播放器”B．点击打开后，会播放默认的一个coco的广告C．点击标题栏的按钮可以打开文件浏览器D．点击视频文件，会提示使用的播放器E．选择“艾文视频播放器”打开后，按ctrl+f12，切换到横屏，发现视频并没有中断，而是继续播放3．源码分析A．图片都是网上找的，还有就是自己收藏的地方翻出来的，不多讲了。

AndroidGSYVideoPlayer视频播放器功能的实现
AndroidGSYVideoPlayer视频播放器功能的实现GSYVideoPlayerGSYVideoPlayer ⼀个基于IJkPlayer的播放器⽀持调节声⾳亮度边播边缓存使⽤了AndroidVideoCache；ExoPlayer使⽤SimpleCache⽀持多种协议h263\4\5、Https、concat、rtsp、hls、rtmp、crypto、mpeg等等简单滤镜（马赛克、⿊⽩、⾊彩过滤、⾼斯、模糊、模糊等等20多种）、动画、（⽔印、画⾯多重播放等）视频第⼀帧、视频帧截图功能，视频⽣成gif功能。
调整显⽰⽐例:默认、16:9、4:3、填充；播放时旋转画⾯⾓度（0,90,180,270）；镜像旋转IJKPlayer、EXOPlayer、MediaPlayer切换、⾃定义内核⼩窗⼝、多窗体下（包括桌⾯）的⼩窗⼝播放。
⽚头⼴告、跳过⼴告⽀持、中间插⼊⼴告功能。
暂停前后台切换不⿊屏；调整不同清晰度的⽀持；⽆缝切换⽀持；锁定/解锁全屏点击功能；进度条⼩窗⼝预览可⾃定义渲染层、⾃定义管理层、⾃定义播放层（控制层）、⾃定义缓存层使⽤依赖1、JCenter 引⼊⽅法（推荐）你可以选择下⾯三种的其中⼀种，在module下的build.gradle添加。
