English doc

RTMPX是一个android的rtmp推流库，采集使用camerax，支持60fps，编码使用mediacodec硬编码，推流使用了librtmp。

30fps.mp4

60fps.mp4

支持的功能

• 60帧预览、推流(理论上支持更高，只要手机支持，目前pixel2最高设置240fps，但是没效果)
• 边推流边录制(保存到本地)

已知问题

• 部分机型在竖屏推流60fps的时候性能不够，导致libyuv旋转需要很长时间(例如pixel2，I帧旋转要12ms)，导致达不到60fps
• 等你发现

待优化

• 添加注释
• 支持滤镜
• 竖屏libyuv旋转时长优化

怎么使用(参考示例app)

1. 依赖

1) 下载aar(这种集成aar文件的方式，camerax库是必须依赖)

  def camerax_version = "1.0.0"
// CameraX core library using camera2 implementation
    implementation "androidx.camera:camera-camera2:$camerax_version"
// CameraX Lifecycle Library
    implementation "androidx.camera:camera-lifecycle:$camerax_version"
// CameraX View class
    implementation "androidx.camera:camera-view:1.0.0-alpha24"

or

2) mavenCentral远程依赖

implementation 'io.github.luohaohaha:rtmpx:latest'

2. 将CameraXImplView 放入布局

...
 <com.rtmpx.library.camera.widget.CameraXImplView
        android:id="@+id/preview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
...

3. 设置推流配置

  Config config = new Config.ConfigBuilder()
                .withBitRate(1000 * 5000) //码率
                .withPublishUrl("rtmp://192.168.50.170:18888/test/live") //推流url
                .withFrameRate(60)//帧率
                .withVideoWidth(1080)//视频宽 
                .withVideoHeight(1920) //视频高
                .withRecordVideo(false)//是否录制
                .withRecordVideoPath("sdcard/dump.mp4")//录制文件保存文件
                .build();

4. 绑定预览控件

 CameraXImplView mPreview = findViewById(R.id.preview);
 mPreview.setPreviewRange(mConfig.getFrameRate(),mConfig.getFrameRate());
 mPreview.setTargetResolution(mConfig.getVideoWidth(), mConfig.getVideoHeight());
 
 PublisherX mPublisher = new PublisherX(mConfig);
 mPublisher.bindCamera(mPreview);
 mPublisher.setPublishListener(this);
 

5. 开启预览 & 开始推流 / 停止预览 & 停止推流

mPreview.startPreview();
mPublisher.startPublish();

or

mPreview.stopPreview();
mPublisher.stopPublish();

IPublishListener 回调

    /**
     * rtmp连接中
     */
    void onConnecting();

    /**
     * rtmp 连接建立成功
     */
    void onConnected();

    /**
     * rtmp 连接失败
     * @param code error code 失败错误码
     */
    void onConnectedFailed(int code);

    /**
     * 开始推流
     */
    void onStartPublish();

    /**
     * 结束推流
     */
    void onStopPublish();

    /**
     * 开始录制
     */
    void onStartRecord();

    /**
     * 结束录制
     */
    void onStopRecord();

    /**
     * 发送平均帧率统计(带宽不足的情况下会低于设置帧率)
     * @param fps avg fps
     */
    void onFpsStatistic(int fps);

    /**
     * rtmp 断开连接
     */
    void onRtmpDisconnect();

rtmpx's Issues

推流延迟较高且看不到视频

设备为小米6 骁龙835
另外使用了nexus5 骁龙800 同样的情况，
搭建rtmp服务后使用vlc播放rtmp，看不到视频

how to properly receive?

I am trying to receive the RTMP stream

running ffmpeg as rtmp server via ffmpeg -re -f flv -listen 1 -i rtmp://10.10.10.50:8080/live/app -vcodec copy -f flv -listen 1 rtmp://10.10.10.50:1935/live/app

app is configured to publish to rtmp://10.10.10.50:8080/live/app

then i connect the rtmp client via

rtmpdump -r rtmp://10.10.10.50:1935/live/app -R -o - | ffplay -

but all I see is a black screen ...

what setup are you using for devel / testing as for the rtmp server / client?

thx

关于我推流推过去收到的流显示的是绿色的花屏。没显示图像。

為什麼我手機螢幕多旋轉成橫向或直向幾次後，會出現以下的crash?

我直播的XML layout Design tag預覽頁面整個Activity 所有View元件都看不到

我直播的XML layout Design tag預覽頁面整個Activity 所有View元件都會消失看不到
，但其他Activity跟Fragment都正常。
然後在Message會顯示下面的錯誤:
java.lang.IllegalStateException: CameraX is not configured properly. The most likely cause is you did not include a default implementation in your build such as 'camera-camera2'.   at androidx.camera.core.CameraX.<init>(CameraX.java:109)   at androidx.camera.lifecycle.ProcessCameraProvider.getOrCreateCameraXInstance(ProcessCameraProvider.java:181)   at androidx.camera.lifecycle.ProcessCameraProvider.getInstance(ProcessCameraProvider.java:167)   at com.rtmpx.library.camera.widget.CameraXImplView.setUpCamera(CameraXImplView.java:159)   at com.rtmpx.library.camera.widget.CameraXImplView.onAttachedToWindow(CameraXImplView.java:154)   at android.view.View.dispatchAttachedToWindow(View.java:20753)   at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:3490)   at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:3497)   at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:3497)   at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:3497)   at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:3497)   at android.view.AttachInfo_Accessor.setAttachInfo(AttachInfo_Accessor.java:58)

但是我gradle有加:

implementation "androidx.camera:camera-core:${camerax_version}"
implementation "androidx.camera:camera-camera2:${camerax_version}"
// If you want to additionally use the CameraX Lifecycle library
implementation "androidx.camera:camera-lifecycle:${camerax_version}"
// If you want to additionally use the CameraX View class
implementation "androidx.camera:camera-view:${camerax_version}"

不知道是什麼原因?

stream directly from camera not via capturing preview

would it be possible to stream directly from camera?

aka not going thru the preview at all, the preview limits fps at my device (oneplus 8T) to only 30fps even if the sensor supports up to 240fps on full hd ...

為什麼用手機前鏡頭直播，電腦播放器看直播的影像是180度倒過來的?

為什麼用手機直向Portrait前鏡頭直播，電腦播放器看直播的影像是180度倒過來的?
( 但是後鏡頭是正常的)
如果手機橫向(landscape)直播，前後鏡頭在播放器看也是正常的

性能不错，实际测试1080P 30帧没问题，切换摄像头也正常，缺点是线程安全处理得不好

这个代码多线程处理不严谨，稍加修改和断点就容易出现多线程问题。作为camerax学习使用是不错的

Publish(ed) App?

It seems like this could provide a simple, effective, open source alternative to DroidCam.

Have y'all considered making a slightly more advanced Android app with options for the user to specify the publish URL, rather than how it's hard-coded now?

Or is there an app that is built with this? It seems too good! :)

thank you!
