java - 无法在videoview android中播放来自url的视频

Question

我正在尝试在视频 View 中播放我自己的本地服务器上的视频。我给它我的服务器的 URL。

http://admin:admin@192.168.0.3:8732/cam4/ERecordings/4_UNIVIEW_192.168.1.13/01-07-2020/14-39-23.mp4

我可以在任何浏览器中访问此链接并播放视频，但我的应用程序无法播放它。

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

       final VideoView videoView = findViewById(R.id.videoplayer);
        MediaController mediaController = new MediaController(this);
        mediaController.setAnchorView(videoView);
        final ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setMessage("Buffering please wait!!");
        progressDialog.show();
       // Uri uri = Uri.parse("https://archive.org/download/ksnn_compilation_master_the_internet/ksnn_compilation_master_the_internet_512kb.mp4");
        Uri uri = Uri.parse("http://admin:admin@192.168.0.3:8732/cam4/ERecordings/4_UNIVIEW_192.168.1.13/01-07-2020/14-39-23.mp4");
        videoView.setMediaController(mediaController);
        videoView.setVideoURI(uri);
        //videoView.setVideoPath("http://playready.directtaps.net/smoothstreaming/ISMAAACHE/Taxi3_AACHE.mp4");
        videoView.requestFocus();
        videoView.start();
        try{
            videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    progressDialog.dismiss();
                }
            });
        }
        catch (Exception e){
            Toast.makeText(this,"can not play ", Toast.LENGTH_SHORT).show();
        }

    }

}

权限:为了测试，我已授予该应用程序所有权限。

<uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.FLASHLIGHT" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

错误:

W/MediaPlayer: Couldn't open http://admin:admin@192.168.0.3:8732/cam4/ERecordings/4_UNIVIEW_192.168.1.13/01-07-2020/14-39-23.mp4: java.io.FileNotFoundException: No content provider: http://admin:admin@192.168.0.3:8732/cam4/ERecordings/4_UNIVIEW_192.168.1.13/01-07-2020/14-39-23.mp4

我可以从任何浏览器访问它，甚至在移动设备上也是如此。即使 Vlc 和 Mx 播放器 Android 应用程序也可以播放它。如果我输入任何私有(private)服务器地址，那么它就可以正常播放。我在同一个 wifi 网络上。

更新:我在 Android list 中添加了权限 android:usesCleartextTraffic="true"但现在出现错误

E/MediaPlayerNative: error (1, -2147483648)
E/MediaPlayer: Error (1,-2147483648)
D/VideoView: Error: 1,-2147483648

更新 2:- 我将视频文件放入 IIS 服务器中，这次工作正常。但在我的主程序中我使用的是 apache 服务器。早些时候，我使用 Libvlc android 集成，它能够播放视频，但 videoview android 无法播放相同的 url。下面的网址工作正常。

String url = "http://192.168.0.4/a1.ts";

试试这个，它会对你有用，

try {
        val link = "https://www.radiantmediaplayer.com/media/bbb-360p.mp4"
        val videoView = findViewById(R.id.videoview) as VideoView
        val mediaController = MediaController(this)
        mediaController.setAnchorView(videoView)
        val progressDialog = ProgressDialog(this)
        progressDialog.setMessage("Loading video please wait!!!")
        progressDialog.show()
        val video = Uri.parse(link)
        videoView.setMediaController(mediaController)
        videoView.setVideoURI(video)
        videoView.requestFocus();
        videoView.start()
        try {
            videoView.setOnPreparedListener(object : MediaPlayer.OnPreparedListener {
                override fun onPrepared(mp: MediaPlayer) {
                    progressDialog.dismiss()
                }
            })
        } catch (e: Exception) {
            Toast.makeText(this, "can not play ", Toast.LENGTH_SHORT).show()
        }


    } catch (e: Exception) {
        Toast.makeText(this, "Error loading video", Toast.LENGTH_SHORT).show()
    }
