Interface RendererCommon.GlDrawer

  • All Known Implementing Classes:
    GlRectDrawer
    Enclosing class:
    RendererCommon
    public static interface RendererCommon.GlDrawer
    Interface for rendering frames on an EGLSurface with specified viewport location. Rotation, mirror, and cropping is specified using a 4x4 texture coordinate transform matrix. The frame input can either be an OES texture, RGB texture, or YUV textures in I420 format. The function release() must be called manually to free the resources held by this object.

      • drawOes

        void drawOes​(int oesTextureId,
             float[] texMatrix,
             int frameWidth,
             int frameHeight,
             int viewportX,
             int viewportY,
             int viewportWidth,
             int viewportHeight)
        Functions for drawing frames with different sources. The rendering surface target is implied by the current EGL context of the calling thread and requires no explicit argument. The coordinates specify the viewport location on the surface target.

      • drawRgb

        void drawRgb​(int textureId,
             float[] texMatrix,
             int frameWidth,
             int frameHeight,
             int viewportX,
             int viewportY,
             int viewportWidth,
             int viewportHeight)

      • drawYuv

        void drawYuv​(int[] yuvTextures,
             float[] texMatrix,
             int frameWidth,
             int frameHeight,
             int viewportX,
             int viewportY,
             int viewportWidth,
             int viewportHeight)

      • release

        void release()
        Release all GL resources. This needs to be done manually, otherwise resources may leak.
