AVFormatParameters are converted into corresponding private options in
av_open_input_file/stream() compat wrappers, so accessing them from
demuxers is redundant.
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

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.

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.

Move check on frame size after the device is opened and after
device_try_init() is attempted. If the provided size value is 0x0,
perform a VIDIOC_G_FMT ioctl() on the device, which sets size to the
current settings.

The v4l.c check is moved after the eventual automatic size detection,
so the check in that case is performed on the new set values.
