Added new unit tests for FFmpegReader, which tests actual pixel color values against a test video on 2 different frames. Also, made Seek() method private.

Added some new methods to access audio data: channels, samples, etc... Also, added initial unit tests for the FFmpegReader class, including waveform checking against an actual audio file.

Refactored FFmpegReader code a bit, fixed many, many memory leaks, and many valgrind errors. Now the memory seems very stable, and the seeking and stream walking seems very solid.

Replaced last_video_frame and last_audio_frame with a single last_frame variable, and refactored some related code. This fixes a big audio seeking bug.

Refactored the cache class to only apply the max frames against "previous" frames, and allow unlimited number of future frames, to account for different types of files (some which have hundreds of tiny frames, which need large future cache).

Lots of experimental changes with the FFmpegReader, and caching of packets.

1) Successfully got OpenMP working with the video processing method.
...
2) Added new "processing" flag, to help determine if a frame is being worked on in a thread
3) Added a new cache Display() method, for debugging reasons

Make SDL method private, so Python bindings still work

Got ffmpeg and juce compiling and mostly everything working again. FFmpeg is the newest version, and so is JUCE.

Fixed 2 bugs related to audio samples. Each frame can now determine it's own # of samples, due to some sample rates not being divisible evenly into some frame rates. Also, a bug was fixed that injected a bad sample into a frame's samples, when a frame received samples from multiple audio packets.

Fixed a bug where audio was not being resampled to the correct sample format. Also fixed a bug where the audio buffer was not being incremented correctly, and it was duplicating audio samples. There are still a few audio bugs, but it's mostly working now.

Added a method to get the average # of frames over the initial 5 seconds of video, and adjust an invalid framerate, which sometimes FFmpeg detects. Also, a Reader only initializes it's default values 1 time, and only checks frame rate 1 time, regardless of how many times your Open() and Close() the reader.

Fixed tons of issues related to video timebase being different than the video framerate. Also, added new properties for interlaced video, correctly detect pixel ratio, and fixed Display() to adjust for pixel ratio. Also added sample_rate to a frame, so it can playback audio at the correct rate. Refactored FFmpegReader to make most methods private, and only expose the important methods publicly.

Fixed a rounding error on mapping audio samples to frames. Also adjusted the sample rate on the frame.Play() method to 48khz.

Reworked the cache object to use a double sided queue, so I can iterate through it to find the smallest frame, and remove specific frames from the cache. Also, fixed some additional audio bugs, and I finally have the audio being correctly distributed between frame objects.

Added a DisplayWaveform method on a frame, to help debug audio issues. It uses ImageMagick to draw each channel and all samples in each channel.

Some major refactoing of the FFmpegReader, to allow for audio and video packets that are out of order.
