...
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.

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.

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.
