V.0.0.1

Writes 5 files:
0-0baseline-0superfast
0-1main-0superfast
0-2high-0superfast
0-3high10-0superfast
0-4high422-0superfast
0-5high444-0superfast

One for each profile, each file has all the pixel formats and levels (including unsupported ones).

The results are lots of .mov files.
The filename is constructed as follows:
Source-FFv1_5high444_0superfast_L1.1_yuv444p.mov, where Source-FFv1 is the input filename, 5high444 is the profile, 0superfast is the preset (how much the file is compressed), L1.1 is the level, yuv444p is the encoded pixel format.
Unsupported combinations will result in ffmpeg giving an error and a 0kb file.

The code is created on windows, but there's nothing inherently windows-only about it, anyone can convert it to .NET and have it cross platform.

Attached is the debug exe, creates files in the current directory, ready to use.
