* Completing swap-interval implementation for OSX's CALayer usage. Closing Bug 555Sven Gothel2012-04-224-39/+100
| | | | | | | | | | | | - Based on Andres Colubri's initiative and commit 218d67fc0222d7709b21c45792d44501351939c4. - Reading real screen refresh rate ('stolen' from NEWT) - Properly handling swap-interval and vsync-to in native code - Increasing accuracy vsync-to to microseconds Tested manually w/ TestGearsES2AWT.
* FFMPEGMediaPlayer: Fix NPE; Add remarks about binary incompatibility in ↵Sven Gothel2012-04-211-155/+198
| | | | | | | | | | | upcoming version (master branch) We need native structure access methods to deal with API changes in the libav headers, which break binary compatibility! Currently we are binary compatible w/ [0.6 ?, ] 0.7 and 0.8 but not w/ trunk. Tested: Linux, Windows and OSX (self compiled binary)
* Adding initial Libav/FFMpeg GLMediaPlayer implementationSven Gothel2012-04-162-0/+780
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Java classes already slipped through in commit 10935e1ec0d8ed677bc3fddfaa8cd73898a3bcbf - oops. Since we cannot provide a Libav binary (even though Google does in Android and Chrome) due to legal uncertainities .. we dynamically link to an existing Libav / FFmpeg library in a 'relaxed' manner. Ie. we allow certain recent functions to be absent to be able to run on a wider range of Libav versions. Currently tested on Debian Linux and Windows7 64bit/32bit Binaries for Win/OSX: - Windows http://ffmpeg.zeranoe.com/builds/ - OSX http://www.ffmpegx.com/ Features: - Dynamic relaxed linking to Libav (see above) - YUV420P texture lookup function shader stub (conversion to RGB) - 1-copy only (decoder buffer to texture) - simple - uses libavformat's network streaming - fixes some odd PTS values TODO: - Audio output (Should use OpenAL, duh) - Seek works poorly - Offthread multi-texture fetching for smoother animation - Maybe more pixelformat conversions
* TextureSequence Shader Support; GLMediaPlayer uses 'int' where possible; ↵Sven Gothel2012-04-165-191/+135
| | | | | | | | | | | | | General enhancments. For details about TextureSequence/GLMediaPlayer shader collaboration w/ your own shader source, see TextureSequence and TexCubeES2 / MovieSimple demo. TextureSequence allows implementations to provide their own texture lookup function which may provide color space conversion (YUV) .. or other runtime hw-accel features. Have a look at the next commit, which provides an Libav/FFMpeg implementation w/ YUV/RGB shader conversion. MovieCube adds keyboard control (Android: firm touch on display to launch keyboard, don't break it though :)

* GLMediaPlayer*: Revised - Working on buggy MediaPlayer impl. (Android ICS Tegra)Sven Gothel2012-04-093-10/+11
| | | | | | | | | | | | | GLMediaPlayer: Merging 'initStream()' and 'initGL()' to 'initGLStream()' due to incompatible/buggy implementations (Android/Tegra) requiring the GL texture being setup before preparing the stream. This also implies that w/o an GL context we cannot fetch the stream information (size, ..) hence we need to evaluate this detail (FIXME). 'getNextTexture(GL gl, boolean blocking)' can request the impl. to block GLMediaEventListener: The TextureFrame not yet available, adding 'when'
* GLMediaPlayer: API and implementation update. First working version on ↵Sven Gothel2012-04-033-13/+13
| | | | | | | | | | | | | | Android API 14 - Introduce states - Customize / Access texture target,count,features. - Expose TextureFrame. - Use 'long' for all time values in msec. - Mark information optional in API doc (fps, bps, ..)
* Initial commit for AudioVideo (com.jogamp.opengl.av) rework, introducing ↵Sven Gothel2012-04-023-22/+19
| | | | | | | | Android API 14 MediaPlayer impl of GLMediaPlayer. Android API 14 MediaPlayer allows usage of OMX AL direct decode to texture via libstagefright (OMX AL usage included). Status: Untested, not working - Need to fix native OMX IL (stream detect and split) and/or GStreamer implementation.
* API Change [GLProfile/GLContext]: Add notion of hardware acceleration in ↵Sven Gothel2012-02-201-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | GLProfile.get<Profile>() methods. We need to distinguish between software and hardware accelerated OpenGL profiles to allow choosing the proper profiles [default, GL2ES1, GL2ES2, ..] on platforms where both, software and hardware implementations exist (GL, GLES2, ..). Where no preference is being requested, hardware acceleration is favored: GLProfile.getDefault() GLProfile.getGL2ES1() GLProfile.getGL2ES2() Some method signatures needed to change GLProfile: getMaxProgrammable(AbstractGraphicsDevice device) -> getMaxProgrammable(AbstractGraphicsDevice device, boolean favorHardwareRasterizer) GLProfile adds: isHardwareRasterizer() Determination whether a hardware acceleration is being used or not is extended in GLContextImpl by querying the current context's GL_RENDERER string. If the latter contains 'software' (case insensitive) it is not hardware accelerated. At least this works w/ newer Mesa3D impl, where GLX_SLOW_CONFIG is not set!

* GLContextImpl*: createImpl() / makeCurrentImpl() refinement / robostnessSven Gothel2011-11-291-0/+15
| | | | | | | | | | | | | | | createImpl(): If successful must leave context current. makeCurrentImpl(): Is only called if context is not just created, hence the boolean parameter 'boolean newCreatedContext' is removed. This clearifies and actually cleans up the native makeContextCurrent/releaseContext call pairs. MacOSXCGLContext: CGL and NS impl. of native makeContextCurrent/releaseContext uses CGL locking to provide a thread safety. This is recommended in OS X OpenGL documentation on [shared context] multithreaded use cases. Post creation code, as seen in some pbuffer cases is moved to overriden createImpl() methods.

| | | | | | | | | | | | | | | | | | | | | | | Undo 368cbf4462d7f3635c1ef4497424c360b5ccc203: - "use SurfaceUpdateListener() to notify layer", simply use MacOSXCGLContext's swap impl. MacOSXCGLContext: - NSOpenGLImpl.create(): - issues createNSOpenGLLayer() using tex-size (maybe POT) as args - attaches the NSOpenGLLayer to the JAWT layered surface host - NSOpenGLImpl.setSwapInterval() propagates interval to our NSOpenGLLayer impl. - NSOpenGLImpl.swapBuffer() (layer case): - waits for v-sync if enabled (v-sync), or until native 'draw' is finished (tearing) using our pthread/ NSOpenGLLayer synchronization. The latter uses CADisplayLink or CVDisplayLinkRef for v-sync synchronization. - flushes our local ctx - triggers our NSOpenGLLayer to 'draw' - MacOSXPbufferCGLContext create() sets the texture size independently of pbuffer size (POT/NPOT)

It doesn't issue NSOpenGLContext update() by itself, but allows querying and clearing the update flag. - MacOSXOnscreenCGLContext impl drawableUpdatedNotify() - register via ContextUpdater, and use it if available.

Generic aliased methods reside in GLContext* Enable/Disable via GLContext and GLAutoDrawable. To enable the GLDebugOutput feature GLContext.enableGLDebugMessage(true) or GLContext.setContextCreationFlags(GLContext.CTX_OPTION_DEBUG) shall be called _before_ context creation via GLContext.makeCurrent()! In case GLAutoDrawable is being used, GLAutoDrawable.setContextCreationFlags(GLContext.CTX_OPTION_DEBUG) shall be issued before context creation via GLContext.makeCurrent()!. After context creation, the GLDebugOutput feature may be enabled or disabled at any time using this method. Verify both unit tests for usability.
