Big update! Updating all "long int" frame number types to int64_t, so all 3 OSes will produce the same depth and precision on frame numbers. Also removing variable bitrate support temporarily, since it causes more problems than it solves.

Migrating tr1 to std, adding C++11 support to build scripts, fixing crash in FFmpegReader (caused by shared_ptr, buffer, and last_video_frame corruption). Much improved stability with this change. Thanks to Craig and Peter for the help!

Adding additional locks when adding/changing audio data. Reducing FrameMapper to a single frame at a time (increase seek speed and decrease crashes). Fixing crash on Time keyframes where it would sometimes calculate an invalid frame number.

Removing nested OMP processing from FrameMapper. Adding lock inside time mapping (to prevent crashes when speeding up/slowing down clips). Adding omp critial lock to Frame GetAudioChannelsCount() and GetAudioSamplesCount() methods.

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)

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.

Fixing a crash on Windows by using a different overload of AddImage that doesn't do a memcpy. There is still a memory leak on the FFmpegWriter somewhere, which eventually starts to return NULL from av_malloc, and breaks on Windows (and probably other OSes too).

Big memory leak fixes in FFmpegReader and FrameMapper, and fixed logic in Frame Mapper with regards to special framerate conversions (24, 25, and 30)... which were causing some inadvertent audio drift.

Improved detection of missing audio frames, and missing video frames. Also improved logic for giving up on missing frames in general. Also removed some deadlocks related to Seeking (Close() and Open() were deadlocking). The end result is much improved compatability with reading video files.

Fixed a race condition in video playback thread! Also, added new method to get the average magnitude of a range of audio samples.

Adding new dependency: libzmq (ZeroMQ). Adding a new debug logging class powered by sockets and ZeroMQ, to allow a threadsafe way to communicate debug messages to a client application (i.e. openshot-qt). Also, removing unneeded Sleep.h functions. There will be lots more code utilizing ZeroMQ soon.

Fixed a memory corruption issue, where AddImage was being called multiple times (at the same time). Added a lock, and I can no longer reproduce the crash.

Making ImageMagick completely optional. This will simplify packaging on Windows and Mac. Also, reprogrammed Display, DisplayWaveform, Save, and Thumbnail methods, which are much faster now (using Qt).

Fixed many more regressions with audio files not passing cover art to the next frame correctly. Seeking issues, and many related issues to detecting missing frames improved. Also fixed a deadlock in certain seeking cases.

Added wave_color to Clip's JSON properties. Also fixed a bug with adding effects from a JSON diff. Made the background color of a wave visualization transparent, and made the wave graphic come before the effects are processed, which allows the wave to be faded, animated, etc...

Improved support for missing frames and invalid PTS (which result in gaps and duplicate frames). Also changed frame number to larger data type, and did some code clean-up and refactoring. Less crashes, and more video support!

Removed Cache::Exists method, which created all sorts of havoc when being called in quick succession (basically a frame might exist a split second before calling Cache::GetFrame, but then be missing when GetFrame is called).
...
Next Syntax:
frame = Cache::GetFrame(...)
if frame:
....
Also, fixed some issues with MP3 files having the wrong video length detected, and a few other minor issues.

Fixed many audio issues with the FFmpegWriter. Planar formats were not being handled correctly. Framesize was also wrong on some formats. Also, added a new method to a Frame to fill with audio silence. Lastly, cleaned up some unused imports and C++ warnings.

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).

Added new GetQImage method to get a Qt QImage object from an openshot:Frame object. Also refactored the video playback code to use this new method.

Fixed some major issues with the frame mapper. openshot::FrameMapper is now fully multi-threaded. Fixed a bug in calculating the # of samples on a frame (to always be evenly divisible by the # of channels).
