Refactored the audio waveform generation into the Timeline class. Added the ability to set the volume, and the ability to mix layers of audio samples together. Also, made the waveform's have a transparent background, so they can be layered on top of other layers.

Fixed a big audio bug, where varying timestamp values on low precision audio timebases (i.e. 1/1000) would leave small gaps in the audio wave. Also, fixed a few issues related to sample_rate getting lost between the reader and clip and timeline objects.

Improved the compositing engine to more accurately compare doubles and floats.

Updated the FFmpegWriter to use compiler #IF commands to be compatible with older and newer versions of FFmpeg. This is still a work in progress, but many of the newer commands are now being protected.

Added a simple X,Y offset, to speed up basic overlays.

Replaced the opacity() method with the IM quantumOperator method, which allows me to simply multiply the alpha percentage to each alpha value, and fixed a bug in the ImageReader which prevented copying pixel data between frames.

Added in openMP code to improve performance on the timeline layer merging, which is very CPU intensive.

Added gravity, scale type, and percentage based X,Y location settings. All the basic transformation methods are now working. You can layer, move, fade, snap, rotate, and scale clips on the screen.

Integrated sub-pixel positioning using the distort operator. Not quite working yet.

The timeline classes are finally working correctly, and have the following features:
...
1) Layers (unlimited # of layers)
2) IN, OUT, and Position (time)
3) X, Y offset
4) Alpha
5) Rotation
6) Transparency + compositing + overlays

Integrated more timeline code, such as compositing layers... but they don't work yet

Yet another huge refactor, to use shared_ptr objects instead of actual pointers, due to the difficulties in managing the lifecycle of pointers between the timeline, clip, and readers. Seems to work great, and solves all sorts of bugs. =)

Fixed a regression with audio files and seeking, added a few new methods, and more accurately detect the End() of clips.

Another huge refactor and lots of big fixes! Time mapping now works... mostly. The jumpy / glitchy images have been solved by copying the AVFrame into an AVPicture, which does not get clobbered on the next decode.
...
Also, added a new frame number overaly (in the top, left part of the image), and a new AddColor() method, to change the size and color of the frame's image...
Padded the end of the FFmpegWriter / WriteTrailer() method, to avoid having a codec ignore the last many frames.

Added new method to adjust the min value of a valid frame number, added a new unlimited cache option, and fixed a bug which was preventing the timeline from calling GetFrame correctly. Now timelines, clips, and readers are working together nicely.

Fixed a regression with the FFmpegReader, to always get frame 1 first, to calucate the PTS offsets, etc... Also, fixed a bug on the timeline, and now i'm 1 step closer to having it all work. =)

Added a Rotate() method to a Frame object. Added new methods on a clip to translate frame numbers (FrameMapper and Time Curves). Now, the Timeline, Clip, and Readers are all working with animation curves. Pretty cool!

Implemented the Close() method, so it closes all clips' readers on the timeline

Refactored constructor() methods on readers again, to call Open() and then Close() methods automatically, to populate the info struct. And moved the GetFrame() call out of the Open() method, because it was unneeded and slowed down the Open() method.

Added some functionality to the timeline GetFrame() method, and build a way to update the list of opened clips, to manage which files are open and closed, etc...

A big refactor of the Open() method on Readers, and the constructor of Readers. All resource consuming code has been moved into the Open() methods, so the Clips and Timeline can control them better.
