2013-03-28lavd/v4l2: replace ioctl() with v4l2_ioctl()Giorgio Vazzana

2013-03-12lavd/v4l2: fix bug in init_convert_timestamp()Giorgio Vazzana
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.

2013-01-31lavd/v4l2: read the correct time per frame from devices that support a standardGiorgio Vazzana
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>
2013-01-31lavd/v4l2: add list_standards optionGiorgio Vazzana

2013-01-28lavd/v4l2: use avcodec_find_decoder in list_formatsStephan Hilb
Because libavdevice/v4l2 is a demuxer, it makes sense to look for decoders instead of encoders when listing the formats supported by the device. Signed-off-by: Stefano Sabatini <stefasab@gmail.com>
2013-01-27lavd/v4l2: select input immediately after opening the deviceGiorgio Vazzana
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]).

errors 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.
