Android 中的 MediaPlayer 和 VideoView 有什么区别

Question

I was wondering if there's a difference between them when it comes to streaming videos.

I know VideoView can be used for streaming and what is Mediaplayer for? As far as I know, MediaPlayer can do the same thing as VideoView right?

Can anyone give me the answer?

And if I want to stream video from the server by using RTSP to Android, which one should I start with? VideoView or MediaPlayer ?

Any suggestion?

Answer 1

Was asking the same question and as I understood from what Mark (CommonsWare) advised on numerous threads here, VideoView is a wrapper (200 hundred lines of code) for MediaPlayer and SurfaceView to provide embedded controls.

He also kindly shared some examples:

https://github.com/commonsguy/vidtry/blob/master/src/com/commonsware/android/vidtry/Player.java

and example from android sdk http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/media/MediaPlayerDemo.html

Also some people had issues playing video on emulator, so make sure to test it on actual device if you have issues

Answer 2

VideoView is essentially a View that is tied to a MediaPlayer to make it a lot easier to implement videos in your app. If you aren't doing much custom work, VideoView is the way to go.

That said, you can also pass the RTSP link off to the system to use the most appropriate app for playing the video, which is even easier to do:

String url = "rtsp://yourrtsplink.com/blah";
Uri uri = Uri.parse(url);
startActivity(new Intent(Intent.ACTION_VIEW, uri));

Video should be tested on a device, since emulator playback is poor, and you should also be aware that RTSP requires an extra port to be open, which is blocked by some firewalls.

Answer 4

VideoAdView 是 MediaPlayer 和 SurfaceView 的包装器，使用 VideoView 实现视频播放器比使用 MediaPlayer 更容易，如果视频文件存储在应用程序的内部存储中，请使用内容提供程序或将它们存储为世界可读，否则将不工作
