Android多功能视频播放器GSYVideoPlayer开发流程

今天，和大家分享一个开源的多功能视频播放器 - GSYVideoPlayer，支持弹幕，滤镜、水印、gif截图，片头广告，声音、亮度调节等众多功能，这里就利用它来实现一个标准的视频播放器，那么，话不多说，Go ~

GSYVideoPlayer 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

引入依赖

maven { url 'https://jitpack.io' }maven { url "https://maven.aliyun.com/repository/public" }

//完整版引入 implementation 'com.github.CarGuo.GSYVideoPlayer:GSYVideoPlayer:v8.3.3-release-jitpack' //是否需要AliPlayer模式 implementation 'com.github.CarGuo.GSYVideoPlayer:GSYVideoPlayer-aliplay:v8.3.3-release-jitpack'

开发设置

设置 Activity 的 configChanges 和 screenOrientation

<activity
android:name=".MainActivity"
android:exported="true"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize|screenLayout|smallestScreenSize|uiMode"
android:screenOrientation="fullSensor" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<com.shuyu.gsyvideoplayer.video.StandardGSYVideoPlayer
android:id="@+id/videoPlayer"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
设置要播放的视频链接videoPlayer = findViewById(R.id.videoPlayer)
videoPlayer.setUp(videoUrl, true, "title")
如果你想添加视频封面的话，可以这样设置val coverImg = ImageView(this)
coverImg.setImageResource(R.drawable.cover)
videoPlayer.thumbImageView = coverImg

具体实现

隐藏自带的标题和返回键videoPlayer.titleTextView.visibility = View.GONE
videoPlayer.backButton.visibility = View.GONE
设置旋转，横屏显示orientationUtils = OrientationUtils(this, videoPlayer)
videoPlayer.fullscreenButton.setOnClickListener {
orientationUtils.resolveByClick()
}
开始播放videoPlayer.startPlayLogic()
除此之外，还需处理一下生命周期override fun onPause() {
super.onPause()
videoPlayer.onVideoPause()
}
override fun onResume() {
super.onResume()
videoPlayer.onVideoResume()
}
override fun onDestroy() {
super.onDestroy()
GSYVideoManager.releaseAllVideos()
orientationUtils.releaseListener()
}
在横屏时，如果想点击返回键回到竖屏而不是退出的话，需要重写 onBackPressedoverride fun onBackPressed() {
if (orientationUtils.screenType == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {
videoPlayer.fullscreenButton.performClick()
return
}
videoPlayer.setVideoAllCallBack(null)
super.onBackPressed()
}
如果，视频是以列表的形式展现的话，也是OK的，首先搞个RecyclerView<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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"
tools:context=".VideoListActivity">
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/video_recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
编写item布局<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="30dp">
<com.shuyu.gsyvideoplayer.video.StandardGSYVideoPlayer
android:id="@+id/item_player"
android:layout_width="match_parent"
android:layout_height="300dp" />
</LinearLayout>
RecyclerView适配器class VideoAdapter(private val urlList: List<String>, private val context: Context) :
RecyclerView.Adapter<VideoAdapter.ViewHolder>() {
inner class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {
val itemPlayer: StandardGSYVideoPlayer = view.findViewById(R.id.item_player)
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val view = LayoutInflater.from(context).inflate(R.layout.item_video, parent, false)
return ViewHolder(view)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
//配置StandardGSYVideoPlayer
with(holder.itemPlayer) {
setUpLazy(urlList[position], true, null, null, "title")
//隐藏标题和返回键
titleTextView.visibility = View.GONE
backButton.visibility = View.GONE
//全屏按键
fullscreenButton.setOnClickListener {
holder.itemPlayer.startWindowFullscreen(context, false, true)
}
//防止错位设置
playPosition = position
//是否根据视频尺寸，自动选择横竖屏全屏
isAutoFullWithSize = true
//音频焦点冲突时是否释放
isReleaseWhenLossAudio = false
//全屏动画
isShowFullAnimation = true
//不能触摸滑动
setIsTouchWiget(false)
}
}
override fun getItemCount() = urlList.size
}
Activityval videoRecyclerView = findViewById<RecyclerView>(R.id.video_recyclerView)
val layoutManager = LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)
videoRecyclerView.layoutManager = layoutManager
//GlobalUrl.urlList为视频链接集合
val videoAdapter = VideoAdapter(GlobalUrl.urlList, this)
videoRecyclerView.adapter = videoAdapter
videoRecyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener() {
override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
super.onScrolled(recyclerView, dx, dy)
//可见区域的第一个item
val firstPosition = layoutManager.findFirstVisibleItemPosition()
//可见区域的最后一个item
val lastPosition = layoutManager.findLastVisibleItemPosition()
//播放的位置
val playPosition = GSYVideoManager.instance().playPosition
if (playPosition >= 0) { //说明有播放
if (playPosition < firstPosition || playPosition > lastPosition) {
if (GSYVideoManager.isFullState(this@VideoListActivity)) {
return
}
GSYVideoManager.releaseAllVideos()
videoAdapter.notifyDataSetChanged()
}
}
}
})
别忘了对返回键和生命周期的处理哦override fun onBackPressed() {
super.onBackPressed()
if (GSYVideoManager.backFromWindowFull(this)) {
return
}
super.onBackPressed()
}
override fun onPause() {
super.onPause()
GSYVideoManager.onPause()
}
override fun onResume() {
super.onResume()
GSYVideoManager.onResume()
}
override fun onDestroy() {
super.onDestroy()
GSYVideoManager.releaseAllVideos()
}
