ijkPlayer
ijkPlayer是BiliBili公司维护的一个开源工程,基于ffmpeg开发的一个播放器软件,支持Android和iOS平台,整个ijkplayer就是以ffplay为基础,如果只是使用它进行播放,集成也较为简单,使用也和MediaPlayer差不多,但是要定制化需求,就有一定的门槛高度。支持软硬编解码,支持倍速播放,可以定制化集成需要的功能,集成占用体积也很小,更详细的解释参看下面官方介绍:

ExoPlayer
ExoPlayer 是google推出的开源播放器,主要是集成了Android 提供的一套解码系统来解析视频和音频,将MediaCodec封装地非常完善,形成了一个性能优越,播放稳定性较好的一个开发播放器。
ExoPlayer is an application level media player for Android. It provides an alternative to Android’s MediaPlayer API for playing audio and video both locally and over the Internet. ExoPlayer supports features not currently supported by Android’s MediaPlayer API, including DASH and SmoothStreaming adaptive playbacks. Unlike the MediaPlayer API, ExoPlayer is easy to customize and extend, and can be updated through Play Store application updates.
Documentation
- The developer guide provides a wealth of information to help you get started.
- The class reference documents the ExoPlayer library classes.
- The release notes document the major changes in each release.
Using ExoPlayer
Via jCenter
The easiest way to get started using ExoPlayer is by including the following in your project's build.gradle
file:
compile 'com.google.android.exoplayer:exoplayer:rX.X.X' where rX.X.X is the your preferred version. For the latest version, see the project's Releases. For more details, see the project on Bintray. As source ExoPlayer can also be built from source using Gradle. You can include it as a dependent project like so: // settings.gradle include ':app', ':..:ExoPlayer:library' // app/build.gradle dependencies { compile project(':..:ExoPlayer:library') } As a jar If you want to use ExoPlayer as a jar, run: ./gradlew jarRelease and copy library.jar to the libs folder of your new project.
总结
ijkplayer结构比较相对比较清晰,可扩展性较差,基本上没有提供modules供开发者二次开发,官方更新比较慢,值得欣慰的是,好多开发者基于ijkplayer做了扩展,填了非常多的坑,往上资料非常多;
VLC对点播的支持比较好,但是工程庞大,接入或二次开发难度比较大;
SmartPlayer对RTSP和RTMP直播播放支持非常优秀,毫秒级延迟,稳定性比较好;
ExoPlayer不太适合直播,视频解码无法接入软解,可扩展性一般,而且只支持Android平台。
