* lavd/v4l2: simplify codeGiorgio Vazzana2013-03-09
| | | | | | | struct buff_data contains a pointer to struct video_data, so passing the file descriptor again is redundant. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* lavd/v4l2: correctly handle error conditions in mmap_read_frame()Giorgio Vazzana2013-03-09
| | | | | | | | | In particular: 1) save errno before it (possibly) gets overwritten by other calls 2) do not forget to enqueue the buffer again in case of error Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | | | | | | | | | | | just one buffer left available This will avoid the possibility that we dequeue more buffers than we have obtained from the v4l2 driver. Fixes ticket #1570 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* | avformat/lavfi: force probesize to cover at least 30 framesMichael Niedermayer2013-02-28
| | | | | | | | | | | | | | | | | | | | | | | | 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.

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

| * | 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>

* | lavd/v4l2: use avcodec_find_decoder in list_formatsStephan Hilb2013-01-28
| | | | | | | | | | | | | | | | 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>
* | lavd/v4l2: select input immediately after opening the deviceGiorgio Vazzana2013-01-27
| | | | | | | | | | | | | | | | | | | | | | | | 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]).
