This prevents out of array reads. An alternative solution would be
to check the index but this would require several checks in the
inner loops

Yet another alternative would be to change the index reset logic
but this likely would introduce a difference to the binary decoder

Because libavdevice/v4l2 is a demuxer, it makes sense to look for
decoders instead of encoders when listing the formats supported by the

After opening the device, the first thing we should do is selecting the
input. This is because the image formats (VIDIOC_ENUM_FMT ioctl) and the
standards (VIDIOC_ENUMSTD ioctl) supported may depend on the selected
input ([1] and [2]).

Make device_try_init() return an error value, and allow to properly
report errors which are not due to a wrong pixel/codec configuration.

In particular, report intelligible feedback in case of busy device.

The options have been deprecated and are non-operational since more than
two years.
