Android使用VLC播放摄像头RTSP流

1.修改项目build.gradle,增加maven库地址

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://dl.bintray.com/videolan/Android" }
    }
}

2.修改模块build.gradle,增加依赖

// VLC
implementation 'org.videolan.android:libvlc-all:3.1.12'

3.布局文件中加入VLCVideoLayout

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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">

    <org.videolan.libvlc.util.VLCVideoLayout
        android:id="@+id/video_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

4.增加VLCManager

import android.content.Context;
import android.net.Uri;

import org.videolan.libvlc.LibVLC;
import org.videolan.libvlc.Media;
import org.videolan.libvlc.MediaPlayer;
import org.videolan.libvlc.util.VLCVideoLayout;

import java.util.ArrayList;

public class VLCManager {
    private static final boolean USE_TEXTURE_VIEW = false;
    private static final boolean ENABLE_SUBTITLES = true;

    private VLCVideoLayout mVideoLayout;

    private LibVLC mLibVLC;
    private MediaPlayer mMediaPlayer;

    public VLCManager(Context context, VLCVideoLayout videoLayout) {
        ArrayList<String> options= new ArrayList<>();
        options.add("-vvv");
        options.add("--h264-fps=20");
        options.add("--hevc-fps=20");
        mLibVLC = new LibVLC(context, options);
        mMediaPlayer = new MediaPlayer(mLibVLC);

        mVideoLayout = videoLayout;
    }

    public void play(String url) {
        mMediaPlayer.attachViews(mVideoLayout, null, ENABLE_SUBTITLES, USE_TEXTURE_VIEW);

        Media media = new Media(mLibVLC, Uri.parse(url));
        media.addOption(":network-caching=300");
        mMediaPlayer.setMedia(media);
        media.release();

        mMediaPlayer.play();
    }

    public void onStop() {
        if (mMediaPlayer != null) {
            mMediaPlayer.stop();
            mMediaPlayer.detachViews();
        }
    }

    public void onDestroy() {
        if (mMediaPlayer != null) {
            mMediaPlayer.release();
        }
        if (mLibVLC != null) {
            mLibVLC.release();
        }
    }
}

5.修改MainActivity

import android.os.Bundle;

import androidx.appcompat.app.AppCompatActivity;

import org.videolan.libvlc.util.VLCVideoLayout;

public class MainActivity extends AppCompatActivity {
    private VLCManager mVLCManager;

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

        mVLCManager = new VLCManager(this, (VLCVideoLayout) findViewById(R.id.video_layout));
        mVLCManager.play("rtsp://192.168.1.1:554/user=admin&password=&channel=1&stream=0.sdp?real_stream");
    }

    @Override
    protected void onStop() {
        super.onStop();
        if (mVLCManager != null) {
            mVLCManager.onStop();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (mVLCManager != null) {
            mVLCManager.onDestroy();
        }
    }
}
