如何录制 SurfaceView 预览 [英] How to record SurfaceView preview

问题描述

我正在开发一个应用程序，在该应用程序中我仅将 Surface View 用于帧预览.谁能告诉我如何录制 SurfaceView 预览的视频?

解决方案

你有 3 种可能性:

1 - 捕获 SurfaceView 的每一帧并将所有捕获的位图存储到一个数组中，之后您可以使用 MediaRecord

以下是其工作原理的完整示例:ViewRecorder

2 - 使用 EZFilter (我已经测试过)，有点长，但值得一试:

XML:

<!--将您的 SURFACEVIEW XML 放在这里--></cn.ezandroid.ezfilter.view.glview.GLLinearLayout></RelativeLayout>

JAVA:

GLLinearLayout mLinearLayout = findViewById(R.id.gl_layout);ISupportRecord mSupportRecord;TextureFitView 渲染视图；RenderPipeline mRenderPipeline = new RenderPipeline();mRenderPipeline.setRenderSize((int)surfaceWidth,(int)surfaceHeight);mRenderPipeline = EZFilter.input(mLinearLayout).addFilter(null).enableRecord(videoPath, true, false).into(renderView);for (GLRender 渲染:mRenderPipeline.getEndPointRenders()) {如果(呈现 ISupportRecord 的实例){mSupportRecord = (ISupportRecord) 渲染；}}mSupportRecord.setRecordSize(surfaceWidth,surfaceHeight);

何时开始录制:

 private void startRecording() {this.mSupportRecord.startRecording();this.mSupportRecord.enableRecordAudio(false);}

停止录制:

 private void stopRecording(){如果(mSupportRecord ！= null)mSupportRecord.stopRecording();}

3 - 您可以使用 FFmpeg

捕获整个屏幕并裁剪录制的视频

I am working on an app in which I am using Surface View only for preview of frames. Can anyone tell me how can I record videos of this SurfaceView preview?

解决方案

You have 3 possibilities :

1 - Capture each frame of your SurfaceView and store all the captured bitmaps into an array, after that you can encode it to a video file using MediaRecord

Here's a full example of how it works : ViewRecorder

2 - Using EZFilter (I've already tested), It's a little long but it's worth a try :

XML :

<RelativeLayout
            android:id="@+id/frm"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:animateLayoutChanges="true"
            android:gravity="center_vertical|center_horizontal">


            <cn.ezandroid.ezfilter.core.environment.TextureFitView
                android:id="@+id/render_view"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerInParent="true"
                android:layout_centerHorizontal="true"
                android:layout_centerVertical="true"
                android:layout_gravity="center"
                android:visibility="gone" />

            <cn.ezandroid.ezfilter.view.glview.GLLinearLayout
                android:id="@+id/gl_layout"
                android:layout_width="wrap_content"
                android:gravity="center"
                android:layout_height="wrap_content"
                android:layout_centerInParent="true"
                android:layout_centerHorizontal="true"
                android:layout_centerVertical="true"
                android:background="@android:color/transparent"
                android:visibility="invisible">

                <!--PUT YOUR SURFACEVIEW XML HERE-->
    
            </cn.ezandroid.ezfilter.view.glview.GLLinearLayout>
        </RelativeLayout>

JAVA :

GLLinearLayout mLinearLayout = findViewById(R.id.gl_layout);
ISupportRecord mSupportRecord;
TextureFitView renderView;
RenderPipeline mRenderPipeline = new RenderPipeline();

mRenderPipeline.setRenderSize((int) surfaceWidth, (int) surfaceHeight);
                mRenderPipeline = EZFilter.input(mLinearLayout)
                        .addFilter(null)
                        .enableRecord(videoPath, true, false)
                        .into(renderView);
                for (GLRender render : mRenderPipeline.getEndPointRenders()) {
                    if (render instanceof ISupportRecord) {
                        mSupportRecord = (ISupportRecord) render;
                    }
                }
                mSupportRecord.setRecordSize(surfaceWidth, surfaceHeight);

When you want to start recording :

 private void startRecording() {
        this.mSupportRecord.startRecording();
        this.mSupportRecord.enableRecordAudio(false);
 }

To stop recording :

  private void stopRecording(){
       if (mSupportRecord != null) 
            mSupportRecord.stopRecording();
  }

3 - You can capture the whole screen and crop the recorded video using FFmpeg
