* v4l2: make possible to disable libv4l2 at runtime.Clément Bœsch2013-05-22
| | | | | | Also disable it by default since it looks currently buggy. The usefulness of such library is mostly limited to backward compatibility with very old devices.

* lavd/v4l2: move pixel format conversion code to a separate place.Clément Bœsch2013-05-20
| | | | This will be shared with the output device.

| | | | | | | | | | | | 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.

| * | lavd/v4l2: read the correct time per frame from devices that support a standardGiorgio Vazzana2013-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. [1] http://linuxtv.org/downloads/v4l-dvb-apis/standard.html Signed-off-by: Stefano Sabatini <stefasab@gmail.com>
