f609ddba05 Fix incorrect FPS value returned by cap.get(CV_CAP_PROP_FPS)
Current implementation returns NaN for some configs of FFMPEG, call default get_fps() instead (as also used by PROP_POS_MSEC)

eac5cab5cb cap_v4l: implement PROP_CONVERT_RGB
allows disabling automatic conversion to RGB for certain formats. If
conversion is disabled the returned image just points to the underlying
buffer, so no memcpy is performed.

Note that we do not check image size in retrieve frame any more as it
can not possibly while the device is streaming.
Furthermore this code was disabled altogether by the wrong ifdef in the
previous commit.

5e62e71b13 fix wrong ifdef bracketing
in the case of HAVE_CAMV4L2 && !HAVE_CAMV4L there was no body for the if
statement.

5525cc4d09 implement CAP_PROP_MODE, CAP_PROP_FOURCC and CAP_PROP_FORMAT
do not use a custom enum instead of the V4L2 fourcc defines for palette.
This way we can easily implement CAP_PROP_FOURCC and CAP_PROP_MODE.

c0fe522c9d allow changing FPS and Image Size using V4L2
use logic similar to cap_libv4l: replace icvSetVideoSize by v4l2_reset
as it was not used for V4L1, the actual frame format is negotiated in
try_palette_v4l2 and the stream has to restarted anyway.

18034a5138 allow icvGetPropertyCAM_V4L to return zero
now icvGetPropertyCAM_V4L behaves the same as in cap_libv4l. This also
fixes passing boolean values.

f88e9a748a update ffmpeg support
Migration have been done for these ffmpeg/libav changes:

2013-12-11 - 29c83d2 / b9fb59d,409a143 / 9431356,44967ab / d7b3ee9 - lavc 55.45.101 / 55.28.1 - avcodec.h
  av_frame_alloc(), av_frame_unref() and av_frame_free() now can and should be
  used instead of avcodec_alloc_frame(), avcodec_get_frame_defaults() and
  avcodec_free_frame() respectively. The latter three functions are deprecated.

2012-10-08 - ae77266 / 78071a1 - lavu 51.74.100 / 51.42.0 - pixfmt.h
  Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*.
  To provide backwards compatibility, PixelFormat is now #defined as
  AVPixelFormat.
  Note that this can break user code that includes pixfmt.h and uses the
  'PixelFormat' identifier. Such code should either #undef PixelFormat
  or stop using the PixelFormat name.

fbcf5f0918 cvCreateCameraCapture: fix using preffered interface
The provided interface id must be removed from the index. Otherwise, the
underlying implementations are using a wrong camera id.

Example:
VideoCapture(800) fails because PvAPI tries to open a camera
on position 800

41d8c4d879 allow specifying apiPreference in VideoCapture when opening a file. Add
a separate function instead of an overload not to change the ABI.

rename VideoCapture paramter 'device' to 'index' in CPP to reflect that
it allows specifying the API.
update comments to explain how to specify the API.
