GSVideo

README file for GSVideo-stable CHANGELOG GSVideo 1.0.0 (2011-10-04) * Using updated gstreamer binaries for Windows and OSX. * Automatic switching between 32 and 64 bits modes. * Added 64 bits support to windows. * Dropped support for OSX 10.5 (Leopard). * Added gst-inspect/gst-launch tools. * Slightly better camera selection in OSX. * Resolution and fps query methods in GSCapture have better error handling. * Renamed some functions (play->start, pause->stop) in GSCapture. * Added newFrame/oldFrame methods to improve performance during playback. * Fixed implementation of jump-to-position method, and added isSeeking() method to use in combination with jump() * Added OpenCV/FaceDetection example showing integration with OpenCV library. * Added finalizers to dipose native resources if they haven't been removed with delete(). * Added missing initialization calls. * Added copy in the buffer destination method to avoid threading issues when combining with GLGraphics/OpenGL. GSVideo 0.9 (2011-05-16) * Added pixel destination mode that allows to copy native frames from gstreamer directly into a destination object, such as a GLTexture from GLGraphics. In this case, the frames are already color-converted in OpenGL's RGBA format, which reduces significantly CPU utilization. * Added GLGraphics category in the examples, showing the use of the new pixel destination mode. * Added better buffering in GSMovieMaker. * Fixed framerate setting in GSMovie and GSPlayer. * Fixed issue when rendering frames with the JAVA2D renderer when the stream is still not initialized. * Removed width>1, height>1 condition from examples using P2D * Updated Capture examples to use default framerate. GSVideo 0.8 (2011-03-15) * Using GStreamer-WinBuilds 0.10.7 Beta 4, and GStreamer 0.10.32 from MacPorts. * Framerate detection for windows. Single backslashes are replaced by double backslashes to avoid path problems in gstreamer. * Added the Raw examples for Player and Pipelines * Implemented RAW mode in GSPipeline and GSPlayer. * Removing streaming examples for the time being * Minor corrections to GettingStartedCapture examples. * Added setEventHandlerObject to GSCapture * Added resolution and framerate query to GSCapture. * Updated Speed example, added Reverse. * Fixed bug 3133972. * Implemented working versions of length, frame, and jump (to frame) methods in GSMovie and GSPlayer. Also added duration, time, and jump (to time) to GSPipeline. * Added Frames example. * Removed Capture2File and FastWebcam examples, added Audio and Capture. * Applied patch by Charl P. Botha which fixes thread issues when reading new frames in GSCapture, GSMovie, GSPlayer, and GSPipeline. * Event listeners in GSMovie, GSPlayer, GSCapture and GSPipeline classes are removed in delete() to avoid memory leaks. * Additional checks and exception handling in the delete() methods. * Fixed color swap problem. Updated pipelines/Test example since now there is no more need to explicity set the colorspace * Finer-grained options to control location of gstreamer libraries. * Added isPlaying(), isPaused(), and isLooping() methods to GSMovie. * Improved mechanism to detect if global installation of gstreamer is available. User can override automatic search by specifying global directory with GSVideo.globalGSteamerPathLinux, GSVideo.globalGSteamerPathMacOSX, and GSVideo.globalGSteamerPathWindows static variables. * Added delete() and dispose() methods to all the classes. Replaced PlayBin with PlayBin2 in GSMovie and GSPlayer. GSVideo 0.7 (2010-08-21) * Library package was split into Linux, Mac and Windows versions. * Support for audio-only pipelines. * Various improvements in GSMovieMaker (new codecs, automatic file format detection). * Added static field GSVideo.passDirectBuffer that allows to control de use of direct buffer passing in gstreamer-java. By default the value is true, which should result in better performance since no new buffers are created when reading video frames. * Added setEventHandlerObject method to GSPipeline and GSPlayer, so the object with the event handler methods can be different from PApplet. * Mac support, now GSVideo on OSX doesn't need additional installs. Exported applications work as well, although they result in large files because are bundled with all the gstreamer libs. * Fixed implementation of GSMovie.speed() method. Now it works as expected, even for backwards playback. * The 64 bits Mac packages are missing the osxvideosrc plugin used for video capture. This is because osxvideosrc relies on the older 32-bit Carbon QuickTime API, which has been deprecated in 64-bit mode. The plugin needs to be rewritten for the newer Cocoa QTKit API (which will work in 32-bit and 64-bit modes). * Switching from global to local gstreamer could lead to the following error: 0:00:00.007000000 3648 0002E788 ERROR GST_REGISTRY gstregistrybinary.c:557: gst_registry_binary_read_cache: Binary registry type not recognized (invalid magic) for file at C:\Users\Andres\.gstreamer-0.10\registry.i686.bin The solution is just to delete the registry.i686.bin file GSVideo 0.6 (2009-07-26 - 2010-05-12) * Added GSMovieMaker.queuedFrames() method (following to suggestion from Job). * Library loading mechanism slightly reworked. * Fixed problem with seek method. * Re-encoded station.mov with H264 * Replaced decodebin with decodebin2 * It also solves some memory handling/performance issues on all platforms (https://sourceforge.net/projects/gsvideo/forums/forum/813596/topic/3683197). * Fixed bug that prevented from running exported applications.
