CV_FOURCC = 4-character code of codec used to compress the frames. For example, CV_FOURCC('P','I','M','1') is MPEG-1 codec,
CV_FOURCC('M','J','P','G') is motion-jpeg codec etc.
CV_FOURCC('P','I','M','1') = MPEG-1 codec
CV_FOURCC('M','J','P','G') = motion-jpeg codec (does not work well)

CV_FOURCC('D', 'I', 'V', '3') = MPEG-4.3 codec
CV_FOURCC('D', 'I', 'V', 'X') = MPEG-4 codec
CV_FOURCC('U', '2', '6', '3') = H263 codec
CV_FOURCC('I', '2', '6', '3') = H263I codec
CV_FOURCC('F', 'L', 'V', '1') = FLV1 codec
List of FOURCC codes is available at http://msdn2.microsoft.com/en-us/library/ms867195.aspx
Under Win32 it is possible to pass -1 in order to choose compression
method and additional compression parameters from dialog.
