This ensures that fps and other values are estimated correctly, the probesize also is intended to limit disk/protocol reads which does not apply to lavfi inputs at all. Fixes Ticket1051 Something similar could be usefull to other input devices Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Set ret to 0 before enumerating standards in v4l2_set_parameters(), avoid use of uninitialized variable. Regression introduced in 60950adc18fe145a235211e75da68ab07123fcaa.

2013-02-02lavd/alsa: simplify reordering functions definition.Nicolas George
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
Since the user is expected to choose the standard by name (with -standard option), add the possibility to list all the supported standards. Signed-off-by: Stefano Sabatini <stefasab@gmail.com>
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]).
