问题 So I am updating my app to use OpenGLES 3.0 to take advantage of transform feedback, but the shader isn't compiling. error: 06-27 17:29:43.299 18593-18627/com.harmonicprocesses.penelopefree E/MyGLRenderer﹕ Could not compile shader 35633: 06-27 17:29:43.299 18593-18627/com.harmonicprocesses.penelopefree E/MyGLRenderer﹕ ERROR: 0:1: 'in' : Syntax error: syntax error INTERNAL ERROR: no main() function!

问题 I'm manually reading a RTP/H264 stream and pass the H264 frames to the Android MediaCodec. I use the "markerBit" as a border for the frames. The MediaCodec is tied to a OpenGL Texture (SurfaceTexture). In general everything works fine. But the Decoder appears to buffer frames. If I put a frame in the decoder it is not rendered immediately to the texture. After I put 2-3 frames more in the decoder the first frame is rendered to the texture. I'm implementing against Android 4.4.4. private

问题 I am having serious trouble with taking screenshot of WKWebview content when there is hardware accelerated content (some specific casino games that are running inside iframe). So far I used the standard way of taking screenshot like everyone suggests: UIGraphicsBeginImageContextWithOptions(containerView.frame.size, true, 0.0) containerView.layer.render(in: UIGraphicsGetCurrentContext()!) //This line helps to fix view rendering for taking screenshot on older iOS devices containerView

问题 I am working on a OpenGL ES 3.0 Android project using Java. I need to implement gamma correction and somewhere I've read that sRGB textures would be supported in OpenGL ES 3.0. So my intention was to call glEnable(GL_FRAMEBUFFER_SRGB) before rendering into the default framebuffer. However, when I try to call GLES30.glEnable(GLES30.GL_FRAMEBUFFER_SRGB) it turns out, there is no GLES30.GL_FRAMEBUFFER_SRGB, but there are some constants for sRGB texture formats like GLES30.GL_SRGB. So, my

问题 I have a very simple app that render a square with opengl, input touch are read by the GLSurfaceView and last position is exchanged with the rendering thread using a volatile variable. What I observe (and as been also very well described in https://www.mail-archive.com/android-developers@googlegroups.com/msg235325.html) is that there is a delay (a lag) between the touch position and the display. When activating the developer option to show touch position, I see that when moving rapidly: the
