Refactored blackmagic capture example into DecklinkCapture.cpp, and added it into libopenshot. Also, added a new, Main_Blackmagic.cpp example program, which invokes the DecklinkCapture.cpp class.
...
Also, built in a 20 frame buffer into the DecklinkCapture.cpp class, to discard old frames, to keep the memory from filling up.

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.

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.

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. =)

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.

Fixed a big regression where the "omp" tag was not correct. Also, restructured the encoder to be much faster, and changed "omp master" to "omp single".

Added pool of software image scalers to the FFmpegWriter / encoder, and removed OMP critical section. Also, refactored some audio and video codecs, and changed "resize" to "scale" for speed improvements.

Fixed a huge bug where the FFmpegWriter was not scaling colors to 8 bit, and that would crash on certain colors being used in an image. Also, added a new, experimental waveform visualization to the encoder.

Huge refactor, switched almost all methods to using pointers for Frames, and moved some key method calls outside the critical OMP sections. Also, refactored the sws scaler, to create a pool of 32 scalers, and give each thread it's own scaler. This refactor resulted in a 40%+ increase in speed on the FFmpegReader class.
...
I also added a cmake build flag for the google perftools library, to assist on profiling performance issues.
