What is MediaCodec surface?

MediaCodec class can be used to access low-level media codecs, i.e. encoder/decoder components. It is part of the Android low-level multimedia support infrastructure (normally used together with MediaExtractor , MediaSync , MediaMuxer , MediaCrypto , MediaDrm , Image , Surface , and AudioTrack .)

What is SurfaceTexture android?

android.graphics.SurfaceTexture. Captures frames from an image stream as an OpenGL ES texture. The image stream may come from either camera preview or video decode.

How do I get a surface from SurfaceTexture?

SurfaceTexture surfaceTexture = textureView. getSurfaceTexture(); Then create the Surface object from the constructor Surface(SurfaceTexture surfaceTexture) that will accept the SurfaceTexture from your TextureView object. Surface surface = new Surface(surfaceTexture);

What is android TextureView?

android.view.TextureView. A TextureView can be used to display a content stream. Such a content stream can for instance be a video or an OpenGL scene. The content stream can come from the application’s process as well as a remote process. TextureView can only be used in a hardware accelerated window.

How do I disable MediaCodec surface?

Disable hardware acceleration

  1. Open Kodi.
  2. Select SYSTEM.
  3. Select SETTINGS.
  4. Select Player. Bottom left is Settings level.
  5. Select Videos.
  6. Scroll down to Processing.
  7. Enable HQ scalers for scaling above.
  8. 1st one disable “Allow hardware acceleration – MediaCodec surface” (uncheck) or make sure the dot is grey.

What is Android surface?

In the context of the Android framework, Surface refers to a lower-level drawing surface whose contents are eventually displayed on the user’s screen. You can draw to it in a separate thread. To draw, start a thread, lock the SurfaceView ‘s canvas, do your drawing, and post it to the Surface .

What is GLSurfaceView?

android.opengl.GLSurfaceView. An implementation of SurfaceView that uses the dedicated surface for displaying OpenGL rendering. A GLSurfaceView provides the following features: Manages a surface, which is a special piece of memory that can be composited into the Android view system.

What is texture surface?

Surface texture is the local deviation of a surface from a perfectly flat plane. The measure of the surface texture is generally determined in terms of its roughness, waviness and form (Bhushan, 2002). Surface textures are usually characterized in terms of roughness parameters using a profilometer.

Is Android a surface?

Surface Duo runs Google Android, albeit a heavily skinned version of the mobile operating system. It actually reminds us of Windows 10 X that will be coming to some other dual-screen Windows devices.

What is a SurfaceView in Android?

A SurfaceView is a custom view in Android that can be used to drawn inside it. The main difference between a View and a SurfaceView is that a View is drawn in the UI Thread , which is used for all the user interaction.

What is surface texture metrology?

Surface metrology is defined as the measurement and characterisation of surface topography [5]. Surface texture is the geometrical irregularities present at a surface. Surface texture does not include those geometrical irregularities contributing to the form or shape of the surface.

What is media decoder?

The Windows Media Audio and Video codecs are a collection of objects that you can use to compress and decompress digital media data. Each codec consists of two objects, an encoder and a decoder. A codec is usually implemented as a pair of COM objects: one for encoding content, and another for decoding content.

How does surfacetexture work in the video encoder?

When using the SurfaceView class, the surfaceCreated () callback creates the EGLContext and EGLSurface instances for the display and the video encoder. When a new frame arrives, SurfaceTexture performs four activities: Acquires the frame. Makes the frame available as a GLES texture. Renders the frame with GLES commands.

How does surfacetexture work on an Android phone?

Android supports GPU post-processing of protected video content. This lets apps use the GPU for complex, nonlinear video effects (such as warps), mapping protected video content onto textures for use in general graphics scenes (for example, using GLES), and virtual reality (VR). Figure 2. Secure texture video playback

What does surfacetexture do when a new frame arrives?

When a new frame arrives, SurfaceTexture performs four activities: Acquires the frame. Makes the frame available as a GLES texture. Renders the frame with GLES commands. Forwards the transform and timestamp for each instance of EGLSurface.

What does call updateteximage do in surfacetexture?

Calling updateTexImage () sets both the timestamp and the transformation matrix. Each buffer that BufferQueue passes includes transformation parameters and a timestamp. Transformation parameters are useful for efficiency. In some cases, source data might be in the incorrect orientation for the consumer.
