2010-11-26	Add struct buffer object	Laurent Pinchart
	Use the new buffer object to hold the buffer size and memory pointer. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-11-26	Fix uninitialized variable warning in video_do_capture()	Laurent Pinchart
	Make sure the variable won't be use uninitialized and silent the warning. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-11-26	Add buffer error flag to information printed after VIDIOC_DQBUF	Laurent Pinchart
	Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-09-29	Add option to make requeue of last buffers configurable	Laurent Pinchart
	When capturing n image with p buffers, dequeued buffers don't need to be requeued in the last n - p iterations. Don't requeue them by default, and add a --requeue-last option to force the old behaviour. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-09-29	Print device bus info when opening the device	Laurent Pinchart
	To differentiate between identically named devices, print the bus info reported by VIDIOC_QUERYCAP. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-08-06	Do not divide by zero.	Sakari Ailus
	If only one buffer was processed the performance measurement calculation caused a division by zero. Do not do show measurements if they are bad. Signed-off-by: Sakari Ailus <sakari.ailus@maxwell.research.nokia.com>
2010-08-06	Basic test pattern support for video output devices	Laurent Pinchart
	Instead of filling video output buffers with 0s, generate and user a test pattern. If the -F argument is given, the test pattern is read from the specified file. The file size must be at equal to or bigger than the image size. If the -F argument is not given, a basic test pattern is generated automatically. Every byte is set to the sum of its X and Y coordinates. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-08-06	Optimise for safer free() usage.	Sakari Ailus
	Signed-off-by: Sakari Ailus <sakari.ailus@maxwell.research.nokia.com>
2010-07-30	Make -c and -F options accept an optional argument	Laurent Pinchart
	The long --capture and --file options have an optional argument, fix the short versions. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-07-29	Do accept CFLAGS and LDFLAGS from environment.	Sakari Ailus
	Signed-off-by: Sakari Ailus <sakari.ailus@maxwell.research.nokia.com>
2010-07-22	Add support for the V4L2_PIX_FMT_Y16 format	Laurent Pinchart
	Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-06-23	Add --offset option to select userspace buffer alignment	Laurent Pinchart
	For driver testing purpose the --offset option can be used to modify the userspace buffers alignment. Instead of a fixed page-boundary alignment, buffers can now be aligned to a fixed offset starting to the beginning of the page. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-06-02	Set the v4l2_buffer::length field when queueing a buffer	Laurent Pinchart
	Userspace buffers size needs to be passed to drivers on VIDIOC_QBUF. Set the v4l2_buffer::length field to the size of the allocated buffer before calling VIDIOC_QBUF. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-06-02	Align userspace buffers to a page size boundary	Laurent Pinchart
	Some devices need userspace buffers to be page-aligned. Use the posix_memalign function instead of malloc to allocate page-aligned buffers. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-05-21	Warn when v4l2_buffer::bytesused has an unexpected value	Laurent Pinchart
	For uncompressed formats in capture devices, the v4l2_buffer::bytesused field should have the same value as the v4l2_pix_format::sizeimage field reported by the VIDIOC_G_FMT ioctl. Print a warning on VIDIOC_DQBUG when the values don't match. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-05-19	Initial import	Laurent Pinchart
	Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
