What's new in GSVideo 1.0.0 Beta
Feb 24, 2012
- 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.
New in GSVideo 0.9 Beta (Jul 11, 2011)
- 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.
New in GSVideo 0.8 Beta (Jul 11, 2011)
- 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.
- 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 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 explicitly 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.
New in GSVideo 0.7 (Jan 8, 2011)
- New:
- 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.
- Fixed:
- Fixed implementation of GSMovie.speed() method. Now it works as expected, even for backwards playback.
- Issues:
- Switching from global to local gstreamer could lead to the following error:
- :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
- Roadmap:
- Streaming examples/classes for 0.8.
- Fixes and refinements towards 1.0 release.
New in GSVideo 0.6 pre4 (May 7, 2010)
- Using GStreamer-winbuilds 10.6 final in windows.
- Updated gstreamer-java from trunk.
- More fixes to library loading mechanism, whould work on OSX now.
- macinstall script also fixed.
