2013-06-10Print parser position on errorSascha Hauer
Most parser functions take a **endp argument to indicate the caller where parsing has stopped. This is currently only used after parsing something successfully. This patch sets **endp to the erroneous position in the error case and prints its position after an error has occured. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> [Remove endp NULL checks spread around the code] Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2013-06-10Print more detailed parse error messagesSascha Hauer
The following errors usually resulted in the same 'Unable to parse link' message: - one of the given entities does not exist - one of the pads of a given entity does not exist - No link exists between given pads - syntax error in link description Add more detailed error messages to give the user a clue what is going wrong.

2013-03-25Fix linking of shared librariesAndreas Bombe
When using libudev, it is actually libmediactl that uses it and not the media-ctl executable. libv4l2subdev uses functions from libmediactl and therefore needs to be linked against it. Signed-off-by: Andreas Bombe <aeb@debian.org> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2013-03-25Add missing stdlib.h and ctype.h includesAndreas Bombe
src/mediactl.c needs ctype.h for its use of isspace(). src/v4l2subdev.c needs stdlib.h for strtoul() and ctype.h for isspace() and isupper(). Signed-off-by: Andreas Bombe <aeb@debian.org> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2012-11-15media: Fix valgrind warningsLaurent Pinchart
valgrind has no way to know that the kernel will fill links and pads arrays passed to an ioctl through __user pointers. Allocate the arrays with calloc() to make sure they get initialized. This also fixes the potential integer overflow. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi>

2012-07-18Replace V4L2 subdev selection targets with the V4L2 onesSakari Ailus
V4L2 selection targets will replace V4L2 subdev selection targets in the near future. As the targets are guaranteed to be the same and the chance is anticipated very soon, replace the subdev targets with more future-proof V4L2 targets.

2012-05-25New, more flexible syntax for formatSakari Ailus
More flexible and extensible syntax for format which allows better usage of the selection API. Continue supporting the old syntax but remove the documentation for it. It was not supported in an official release and its use is thus deprecated. Signed-off-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2012-04-29Compare name length to avoid false positives in media_get_entity_by_nameSergio Aguirre
If two subdevice have names that only differ by a suffix (such as "OMAP4 ISS ISP IPIPE" and "OMAP4 ISS ISP IPIPEIF") the media_get_entity_by_name function might return a pointer to the entity with the longest name when called with the shortest name. Fix this by verifying that the candidate entity name length is equal to the requested name length.

2011-10-10Switch to the LGPLv2.1+ licenseLaurent Pinchart
Mail sent to all contributors on 2011-09-30: Hi everybody, Sakari made me realize today that the media-ctl project is still licensed under the GPL v2+ license, while I would have sworn that we had switched to LGPL a long time ago. I would like to relicense the media-ctl project under the LGPL v2.1+, to allow LGPL-compatible applications and libraries (such as libv4l for instance, or its plugins) to link to libmediactl and libv4l2subdev. As you all have submitted patches that are now included in the media-ctl project, I'm requesting your permission to proceed with the license change. -------------------------------------------------------------------------------- From: Todor Tomov <ttomov@mm-sol.com> To: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Date: 2011-09-30 12:06:17 Hi Laurent, No problems from my side. -- Best regards, Todor Tomov -------------------------------------------------------------------------------- From: "Aguirre, Sergio" <saaguirre@ti.com> To: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Date: 2011-09-30 15:41:45 Hi Laurent, No problem for me. You can go ahead, if everyone else agrees of course. Regards, Sergio -------------------------------------------------------------------------------- From: Sakari Ailus <sakari.ailus@iki.fi> To: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Date: 2011-09-30 16:17:18 I'm in favour of the change, actually I think it's next to mandatory for the library to be useful in a way it was intended.

2011-10-08Move V4L2 subdev format parsing from main.c to subdev.cSakari Ailus

2011-10-08Move link parsing from main.c to media.c, making it part of libmediactlSakari Ailus
This makes it possible to benefit from the link parsing code anywhere the library is being used. dprintf macro will later be replaced with proper debug support. Also fix a case where -1 was returned on error and the user was expected to check the value of errno. Negative error codes are now returned consistently.
