41b68dce4d lavdev: improve feedback in case of invalid frame rate/size 
Show the invalid string in the error message.

While at it also prefer "Could not" over "Couldn't", plain forms are
preferred over contractions (simplify readability, especially for non
English-savvy people).

e60068baeb v4l2: prefer "framerate_q" over "fps" in v4l2_set_parameters() 
The variable is used for containing the parsed value of framerate,
using a lexically consistent name eases readability/understanding.

737eb5976f Merge libavcore into libavutil 
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

c6610a216e Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. 
This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

8621a37d9f In video4linux2, in the case the timebase value in ap is 0/0, read the 
timebase value already set in the driver, and set it back in the codec
stream, rather than leaving the invalid value of 0/0.

In particular, fix ffmpeg grabbing timestamps when the timebase value
is not set through the CLI.
