Giorgio Vazzana ee4a658695 lavd/v4l2: fix bug in init_convert_timestamp()
The current code returned a period=0, resulting in identical pts for all frames
after time-filtering. This is because AV_TIME_BASE_Q={1, AV_TIME_BASE} and
not {AV_TIME_BASE, 1}. With this patch the correct period in microseconds is computed.

Giorgio Vazzana 514216d8a9 lavd/v4l2: read the correct time per frame from devices that support a standard
Generally speaking, there are two types of v4l2 devices [1]:

1) devices that support a standard, like PAL or NTFS (tv cards, for example). For
this class of devices the framerate is fixed by the standard (for example PAL uses
25 fps) and the v4l2 driver cannot usually negotiate a different framerate (unless
it can skip frames on the driver side, to save I/O bandwidth).

2) devices for which the notion of standard does not make sense (webcams, for example).
For these devices it is usually possibile to request a desidered framerate.

In either case, the desidered frame rate can be requested when the VIDIOC_G_PARM
ioctl returns the V4L2_CAP_TIMEPERFRAME flag in the capability field.

Currently the code does not check for V4L2_CAP_TIMEPERFRAME and supports only the
second category of devices, returning a time per frame of 0/0 for devices in the
first group that do not permit to negotiate the framerate.

This patch adds support to read the correct framerate in all cases.

Giorgio Vazzana 93d319a582 lavd/v4l2: select input immediately after opening the device
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]).
