Jonathan Thomas	85ac4bf6d2	Updating references to frame number / position to long int, there were still quite a few old "int" declarations, which limits the length of frame number. Also, updated precision of KeyFrames to use double (instead of float) for higher precision, which fixed lots of issues with very long videos (since our FrameMapper used a KeyFrame object to create a map to new frames)	2017-01-24 18:39:17 -06:00
Jonathan Thomas	c53c9364f3	Added new CacheDisk class, which caches frames to the hard drive, dramatically speeding up preview speeds, at the expense of IO operations. New unittests for caching framework. Fixed a few bugs with Frame constructor, which was causing invalid # width & height. Integrated JSON into the cache framework, to quickly share the state of the cache (including ranges of cached frame numbers). Fixed a bug where some Timeline frames could have no audio samples.	2016-09-07 00:40:01 -05:00
Jonathan Thomas	121cfd342d	Fixed a crash when stopping the QtPlayer class (the cache thread was not being correctly ended, and the audio timeslice thread was not being ended). Also fixed a crash when closing the openshot-player executable.	2015-12-04 01:10:40 -06:00
Jonathan Thomas	b612f3339d	Replaced ImagMagick with QImage on almost all key methods and classes. Reprogrammed all effects and the entire rendering pipeline to use QImage and QTransforms, primarily for increases in speed and stability. libopenshot is more than 10X faster on many of the most CPU heavy tasks. This was a huge change, and still has a few minor issues relating to BlackMagick Decklink and Text rendering.... which should be resolved very soon. ... Also, much work has been done on memory management / leak detection, and optimizations with multi-threading... including a new thread cacher class used by the video playback (which is smoother than ever).	2015-06-01 00:20:14 -07:00
