讲解SurfaceTexture BufferQueue has been abandoned在Android开发中，当使用SurfaceTexture类来管理和处理图像数据时，有时可能会遇到BufferQueue...检查SurfaceTexture状态确保SurfaceTexture对象在使用期间没有被意外释放或销毁。...销毁和重建SurfaceTexture如果以上方法无效，你可以尝试销毁当前的SurfaceTexture对象，并在需要时重新创建一个新的对象。...javaCopy code// 在SurfaceTexture数据可用时请求新的图像帧@Overridepublic void onFrameAvailable(SurfaceTexture surfaceTexture...SurfaceTexture类主要用于以下两个方面：相机预览：通过SurfaceTexture，应用程序可以获取相机预览数据帧并对其进行处理。
,然后把camera的预览数据设置显示到SurfaceTexture中，这样就可以在OpenGL中拿到摄像头数据并显示了。...主要步骤 1.OpenGL ES生成纹理 2.OpenGL ES创建SurfaceTexture并绑定 3.OpenGL ES摄像头预览 比如美颜相机那些，处理摄像头数据展示出来，为了提高预览的效率...= new SurfaceTexture(cameraRenderTextureId); surfaceTexture.setOnFrameAvailableListener(this)...= null) { //这里相机拿到surfaceTexture绑定 onSurfaceListener.onSurfaceCreate(surfaceTexture...: camera.setPreviewTexture(surfaceTexture); 预览画面，先通过fbo处理，然后拿到fbo的纹理id渲染即可： @Override public void
SurfaceTexture.OnFrameAvailableListener用于通知TextureView内容流有新图像到来。...SurfaceTextureListener接口用于让TextureView的使用者知道SurfaceTexture已准备好，这样就可以把SurfaceTexture交给相应的内容源。...surfaceTexture, int i, int i2) { Surface surface = new Surface(surfaceTexture); try...surfaceTexture, int i, int i2) { } @Override public boolean onSurfaceTextureDestroyed(SurfaceTexture...SurfaceTexture surfaceTexture) { } } 对应的activity_main.xml <LinearLayout xmlns:android="http://schemas.android.com
把帧数据绘制（缓冲）到Camera的SurfaceTexture中。...Tip：这里会有两个SurfaceTexture，一个时我们自己初始化给Camera的SurfaceTexture，一个是TextureView提供的SurfaceTexture。...= cameraWrapper.surfaceTexture) { cameraWrapper.surfaceTexture?....class ScreenTextureWrapper(override var surfaceTexture: SurfaceTexture?...= surfaceTexture) { egl = Egl() egl!!.initEGL(surfaceTexture!!
1、OpenGL生成纹理 2、纹理绑定到SurfaceTexture上 3、用SurfaceTexture做参数创建Surface 4、MediaCodec解码的视频就往Surface发送，就显示出画面了...sTexture, v_texPosition); } VideoRender.java import android.content.Context; import android.graphics.SurfaceTexture...surfaceTexture; private Surface surface; private OnSurfaceCreateListener onSurfaceCreateListener...surfaceTexture) { if (onRenderListener !...= new SurfaceTexture(textureId_mediacodec); surface = new Surface(surfaceTexture); surfaceTexture.setOnFrameAvailableListener

在CameraGLView主类中创建SurfaceTexture对象,并将纹理绑定其上 而通过SurfaceTexture作为入参可以创建SurfaceHolder,一条路就通了。...= new SurfaceTexture(textureId); surfaceTexture.setOnFrameAvailableListener(this);...public SurfaceTextureEntry createSurfaceTexture() { SurfaceTexture surfaceTexture = new SurfaceTexture...surfaceTexture) { this.id = id; this.surfaceTexture = surfaceTexture; if (VERSION.SDK_INT...); } } public SurfaceTexture surfaceTexture() { return this.surfaceTexture;
Camera#setPreviewDisplay方法设置SurfaceHolder给相机，通常在使用SurfaceView作为预览控件时使用； 通过Camera#setPreviewTexture方法设置SurfaceTexture...设置给Camera即可 camera.setPreviewTexture(surfaceTexture); 方式三、使用GLSurfaceView 使用GLSurfaceVIew作为预览UI控件时，将相机预览数据转化为纹理数据...surfaceTexture) { glSurfaceView.requestRender(); } 除了上面三种方式外，还有一种比较鸡肋的方案来实时显示预览 方式四、利用buffer...最开始设想的挺好的，实际验证的时候发现不向Camera设置SurfaceHolder或SurfaceTexture，单独注册setPreviewCallback接口是不回调数据的。。。...所以这个方案就比较鸡肋了，需要自己构造一个SurfaceTexture设置给Camera，以便让Camera能回调每一帧预览数据给注册方 DEMO // git branch -a // remotes
05 SurfaceTexture 与 Surface SurfaceView 是 Surface + View 的结合体，而 SurfaceTexture 是 Surface + GL Texture...的结合体，SurfaceTexture 可以将 Surface 中最近的图像数据更新到 GL Texture 中。...通过 setOnFrameAvailableListener(listener) 可以向 SurfaceTexture 注册监听事件，当 Surface 有新的图像可用时，调用 SurfaceTexture...绑定 SurfaceTexture surfaceTexture = new SurfaceTexture(texId); // step:3 注册监听事件 surfaceTexture.setOnFrameAvailableListener...(SurfaceTexture surfaceTexture) { // request render } }); 06 MediaCodec
我们要用SurfaceTexture 创建一个Surface，然后将这个Surface作为MediaPlayer的输出表面。...SurfaceTexture的主要作用就是，从视频流和相机数据流获取新一帧的数据，获取新数据调用的方法是updateTexImage。...然后在onSurfaceCreated的最后加上如下代码: surfaceTexture = new SurfaceTexture(textureId); surfaceTexture.setOnFrameAvailableListener...();//获取新数据 surfaceTexture.getTransformMatrix(mSTMatrix);//让新的纹理和纹理坐标系能够正确的对应,mSTMatrix...= new SurfaceTexture(textureId); surfaceTexture.setOnFrameAvailableListener(this);//监听是否有新的一帧数据到来
如果是available状态，则直接打开camera，否则设置surfaceTexture监听 if (mTextureView.isAvailable()) { openCamera...TextureView.SurfaceTextureListener() { @Override public void onSurfaceTextureAvailable(SurfaceTexture...openCamera( width, height); } @Override public void onSurfaceTextureSizeChanged(SurfaceTexture...configureTransform(width, height); } @Override public boolean onSurfaceTextureDestroyed(SurfaceTexture...{ return true; } @Override public void onSurfaceTextureUpdated(SurfaceTexture
生成： SurfaceTexture surfaceTexture = new SurfaceTexture(textureId); surfaceTexture.setOnFrameAvailableListener...(new OnFrameAvailableListener() { @Override public void onFrameAvailable(SurfaceTexture surfaceTexture...) { } }, handler); Surface surface = new Surface(surfaceTexture); 这里简单介绍下SurfaceTexture 。...SurfaceTexture 可以用来捕获视频流中的图像帧，当 SurfaceTexture 中有数据更新时，会触发onFrameAvailable 回调，此时可以调用 updateTexImage 方法从视频流数据中更新当前数据帧...@Override public void onFrameAvailable(SurfaceTexture surfaceTexture) { dealTextureFrame(); } private
来作为预览的画面 * * @param surfaceTexture */ void setPreviewTexture(SurfaceTexture surfaceTexture...因为使用我们期望将Camera中得到的数据传递到纹理上，所以需要setPreviewTexture(SurfaceTexture texture)。让这个SurfaceTexture来承载。...@Override public void setPreviewTexture(SurfaceTexture surfaceTexture) { if (mCamera !...---- SurfaceTexture 可以从图像流中捕获帧作为OpenGL ES纹理。 直接使用创建的纹理，来创建SurfaceTexture就可以了。...() { @Override public void onFrameAvailable(SurfaceTexture surfaceTexture) {
纹理创建成功后返回纹理id，然后创建SurfaceTexture->Surface，将Surface设置给MediaPlayer，代码如下： override fun onSurfaceCreated(...textureId = GLTools.createOESTextureId() var surfaceTexture = SurfaceTexture(textureId)...{ override fun onFrameAvailable(surfaceTexture: SurfaceTexture?)...{ glSurfaceView.queueEvent { surfaceTexture?....textureId = GLTools.createOESTextureId() var surfaceTexture = SurfaceTexture(textureId)
