Added SetMaxSize for image optimizations in QImageReader and FFmpegReader, which lets the timeline pass down the max size to all clips and readers, so they can optionally optimize the size of images (especially useful for optimizing preview performance). Removed convoluted image scaling code in FFmpegReader, and replaced with simpler version. Also, fixed a few regressions from the new Caching code, primarily a crash when reaching the end of the last clip on the timeline.

Adding new CacheBase class. This is the first of many cache related commits, with the goal of building a disk based cache object, to be used by the timeline object if enabled.

Implementing a small memory bug fix with regards to AV_FREE_FRAME and audio_frame. Also adding in support for duration to be set by JSON, to support long videos from openshot-qt.

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.

Added 4 new clip keyframes (channel mapping, channel filter, has_video, and has_audio). These are a bit different though, as they are evaluated as boolean (-1 = ignored, 0 = disabled, 1 = enabled). Also fixed some issues with video playback (where it gets stuck in fast forward), and fixed some race conditions when opening FFmpegReader. Also added more debug output.

Moved AppendDebugMessage to ZmqLogger, and updated 100+ references to use this new function. Removed debug var from readers/writers, and moved it to ZmqLogger.Enable(true/false). This allows debug output from all classes and functions, without any duplicate code. Also added some additional debug output for video playback and audio readers.

Added a lock around adding missing frame images (in FFmpegReader), which might be causing crashes, and fixed a log issue inside the FrameMapper, which also might be affecting performance and/or causing crashes.

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.

When a seek fails, disable seeking with FFmpegReader. This fixes lots of issues with image sequences, but needs more testing to see if it causes issues with normal video files.

FIxed an issue with audio only files with no default height/width set. Also added improved performance when mixing many audio only files (skipping the image processing)

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.

Fixed delay with certain types of audio files which also contained a video stream with a single frame. Added some good 'dont get stuck' logic when checking for gaps in video/audio timestamps, etc...

Improved changing Reader() on the QtPlayer class, and made many thread safety improvements for the FrameMapper.GetFrame method. Also improved the destructors and Close() methods of FFmpegReader and FrameMapper. Some audio-related bug fixes also, related to audio playback.

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).
