2008-07-27V4L/DVB (8523): v4l2-dev: remove unused type and type2 field from video_deviceHans Verkuil
The type and type2 fields were unused and so could be removed. Instead add a vfl_type field that contains the type of the video device. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-07-26V4L/DVB (8482): videodev: move all ioctl callbacks to a new v4l2_ioctl_ops ↵Hans Verkuil
struct All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it. This ensures a clean separation between the const ops struct and the non-const video_device struct.

v4l2-common.h or v4l2-ioctl.h The functions in a header should not belong to another module. The prio functions belong to v4l2-common.c, so move them to v4l2-common.h. The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header and move those functions to it.

2008-05-20Fix a deadlock in the bttv driverArjan van de Ven
vidiocgmbuf() does this: mutex_lock(&fh->cap.vb_lock); retval = videobuf_mmap_setup(&fh->cap, gbuffers, gbufsize, V4L2_MEMORY_MMAP); and videobuf_mmap_setup() then just does mutex_lock(&q->vb_lock); ret = __videobuf_mmap_setup(q, bcount, bsize, memory); mutex_unlock(&q->vb_lock); which is an obvious double-take deadlock. This patch fixes this by having vidiocgmbuf() just call the __videobuf_mmap_setup function instead.

2007-11-04V4L/DVB (6392): bttv: Update initial image size when set via V4L1 VIDIOCMCAPTURETrent Piepho
The V4L1 spec says that the image size should be with with VIDIOCSWIN before requesting buffers with VIDIOCGMBUF and capturing into them with VIDIOCMCAPTURE. But it seems that many apps don't do this. They set the size using the fields in the VIDIOCMCAPTURE ioctl. The driver doesn't know what size to capture until it actually starts to capture. In particular, it doesn't know what size to capture until it has already mmap the captured buffers. Which is quite stupid. Why V4L1 has size and format fields for VIDIOCMCAPTURE I have no idea. Many drivers don't support this, including those using v4l1-compat. The bttv does, which is probably the only reason such broken software is so prevalent. But, the driver doesn't adjust its idea of what size is being captured when it is set this way. If you try to query the driver's current setting with v4l2-ctl, it won't be correct.

2007-11-04V4L/DVB (6391): bttv: SPICT ioctl doesn't work with vlcTrent Piepho
The bttv driver instists that the depth specified in the call to VIDIOCSPICT match the pixel format specified in the same call. vlc doesn't set the depth field, which makes the SPICT ioctl always fail. The V4L1 standard is not clear on how most operation are supposed to work, and this is no exception. The depth field would appear to be entirely redundant, as the pixel format specifies a specific depth. It could be that this field was only meant for output from the *G*PICT ioctl and should be ignored in *S*PICT. This is in fact what the v4l1-compat wrapper does.

2007-07-03V4L/DVB (5808): Bttv: fix v4l1 breaking the driverTrent Piepho
If one uses a V4L *one* application, such as vlc or mplayer's v4l driver, as the first user after the driver is loaded, the driver wedges itself and will never capture properly. Even if one uses a V4L2 application later, it still won't work. If one uses a V4L *two* application first, such as tvtime or mplayer's v4l2 driver, then the driver will be ok. One can then run a V4L1 application, and it will work. It turns out the problem is with norm changing and the crop support that was added in 2.6.21. The driver defaults to PAL, and keeps the last norm it was set too across opens. If one changes the norm via V4L1, the cropping parameters are not reset like they should be, and they'll remain broken across device opens. This patch removes the direct setting of btv->tvnorm in the V4L1 ioctl VIDIOCSCHAN handler. The norm is set via the existing call to set_input(), which calls set_tvnorm(), which will reset the cropping values now that it is able to detect the norm change.

2007-02-21V4L/DVB (5077): Bttv cropping supportMichael Schimek
Adds the missing VIDIOC_CROPCAP, G_CROP and S_CROP ioctls, permitting applications to capture or overlay a subsection of the picture or to extend the capture window beyond active video, into the VBI area and the horizontal blanking. VBI capturing can start and end on any line, including the picture area, and apps can capture different lines of each field and single fields. For compatibility with existing applications, the open() function resets the cropping and VBI capturing parameters and a VIDIOC_S_CROP call is necessary to actually enable cropping. Regrettably in PAL-M, PAL-N, PAL-Nc and NTSC-JP mode the maximum image width will increase from 640 and 768 to 747 and 923 pixels respectively. Like the VBI changes however, this should only affect applications which depend on former driver limitations, such as never getting more than 640 pixels regardless of the requested width. Also, new freedoms require additional checks for conflicts and some applications may not expect an EBUSY error from the VIDIOC_QBUF and VIDIOCMCAPTURE ioctls. These errors should be rare though. So far, the patch has been tested on a UP machine with a bt878 in PAL- BGHI and NTSC-M mode using xawtv, tvtime, mplayer/mencoder, zapping/ libzvbi and these tools: http://zapping.sf.net/bttv-crop-test.tar.bz2 I'd be grateful about comments or bug reports.
