Regression fix: V4L2_PIX_FMT_PRIV_MAGIC should only be set for the VIDEO_CAPTURE and VIDEO_OUTPUT buffer types, and not for any others. In the case of the win format this overwrote a pointer value that is passed in from userspace. Just set it for V4L2_BUF_TYPE_VIDEO_CAPTURE and OUTPUT only. Set it before the callback is called, just as is done for try/s_fmt, and again afterwards in case the driver zeroed it. The latter was missing in try/s_fmt, so add it there as well. Currently it is quite likely that drivers clear priv (that was needed for a long time), so it makes sense to set it twice. Signed-off-by:

V4L2_CID_BASE_LASTP1 should be V4L2_CID_LASTP1. This has probably been wrong since the earliest days of this documentation until I did a copy-and-paste and found out that V4L2_CID_BASE_LASTP1 doesn't actually exist :-) Signed-off-by:

If you have a maximum that is at the limit of what the type supports, and the step is > 1, then you can get wrap-around errors since the code assumes that the maximum that the type supports is ctrl->maximum + ctrl->step / 2. In practice this is always fine, but in artificially crafted ranges you will hit this bug. Since this is core code it should just work. This bug has always been there but since it doesn't cause problems in practice it was never noticed. Signed-off-by:

Hans Verkuil authored
While working with raw and sliced VBI support in several applications I noticed that you really need to know the start linenumbers for each video field in order to correctly convert the start line numbers reported by v4l2_vbi_format to the line numbers used in v4l2_sliced_vbi_format. This patch adds four defines that specify the start lines for each field for both 525 and 625 line standards. Signed-off-by:

The fact that the pixelformat is using a packed RGB format has nothing to do with the colorspace that is being used. Those are very different things. The colorspace decides what color a triplet of RGB numbers actually map to. E.g. a red color with values (255, 0, 0) is a different type of red depending on the colorspace. If the original pixelformat was e.g. YUV in colorspace REC709, then after the conversion to RGB the colorspace is still REC709. Unless the hardware actually converted the colorspace as well from REC709 to sRGB, but that rarely if ever happens. Remove this incorrect comment. Signed-off-by:

The original report from Nikhil was that if data_offset > 0 and bytesused == 0, then the check in __verify_length() would fail, even though the spec says that if bytes_used == 0, then it will be replaced by the actual length of the buffer. After digging into it a bit more I realized that there were several other things wrong: - in __verify_length() it would use the application-provided length value for USERPTR and the vb2 core length for other memory models, but it should have used the application-provided length as well for DMABUF. - in __fill_vb2_buffer() on the other hand it would replace bytesused == 0 by the application-provided length, even for MMAP buffers where the length is determined by the vb2 core. - in __fill_vb2_buffer() it tries to figure out if all the planes have bytesused == 0 before it will decide to replace bytesused by length. However, the spec makes no such provision, and it makes for convoluted code. So just replace any bytesused == 0 by the proper length. The idea behind this was that you could use bytesused to signal empty planes, something that is currently not supported. But that is better done in the future by using one of the reserved fields in strucy v4l2_plane. This patch fixes all these issues. Regards, Hans Signed-off-by:
