2010-08-20Use sysfs to locate devices nodesLaurent Pinchart
Changes made during the v4l2_subdev API review renamed the /dev/subdev* device nodes to /dev/v4l-subdev*. Instead of hardcoding the names in the media-ctl application, use sysfs to retrieve the kernel device name and assume the device node name is identical. This isn't a perfect solution, we should really use libudev, but it will do for now. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-08-16Make format setting optional for -f optionTodor Tomov
This allows to setup crop rectangle or frame interval alone - without format. Signed-off-by: Todor Tomov <ttomov@mm-sol.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2010-08-11Add a --get-format optionLaurent Pinchart
The option takes a pad name as argument and returns the active format (and optional crop settings if available) for that pad. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-08-01Configure cropping on output pads before setting the formatLaurent Pinchart
Image size on output pads depend on the cropping parameters. Cropping must be configured before setting the image size on those pads. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-07-30Be able to add more CFLAGSSergio Aguirre
This allows the gcc compilation to build with extra parameters. For example, if we want to build with -static, we just do: make CFLAGS=-static Signed-off-by: Sergio Aguirre <saaguirre@ti.com>
2010-07-30Create initial .gitignore fileSergio Aguirre
Ignore build generated files as well as the "standard" patches subfolder used by quilt. Signed-off-by: Sergio Aguirre <saaguirre@ti.com>

2010-07-01main.c: fix spaces check in parse_pad()Todor Tomov
Check for spaces before colon also when entity is numeric. Signed-off-by: Todor Tomov <ttomov@mm-sol.com>
2010-07-01Print crop rectangle when printing the topologyLaurent Pinchart
For subdev pads that support cropping, print the active crop rectangle in media_print_topology_text(). Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-07-01V4L2 subdev frame interval supportTodor Tomov
Extend the V4L2 media bus format syntax to support an optional frame interval value. If specified, the frame interval is set on the subdev. Signed-off-by: Todor Tomov <ttomov@mm-sol.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-06-29V4L2 subdev crop supportLaurent Pinchart
Extend the V4L2 media bus format syntax to support an optional crop rectangle. If specified, the crop rectangle is set on the subdev pad. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-06-14Enumerate entities using MEDIA_ENTITY_ID_FLAG_NEXTLaurent Pinchart
Entity IDs don't have to be contiguous. Use the new flag-based enumeration system instead of looping over consecutive IDs. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-06-08strerror takes a non-negative integerLaurent Pinchart
Negative error codes were passed untouched to strerror which then reported an unknown error. Use the positive error code instead. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2010-05-21Don't set formats on remote pads if the remote entity is not a subdevLaurent Pinchart
When setting format on an output pad, the same format is automatically set on the remote pads, if any. As the format setting API is subdev-specific, skip remote pads that belong to a non-subdev entity. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-05-19Zero structures before filling themLaurent Pinchart
The parse_format function fills a v4l2_mbus_framefmt structure but doesn't zero it beforehand. This results in some fields being uninitialized. Fix this. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2010-05-19Return -errno in functions returning a negative error codeLaurent Pinchart
errno is a positive value, fix functions that return errno when they are expected to return a negative error code. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
