v4l2_tvnorm were meant to describe video standards and its names to V4L2 API. However, this were doing by some static structures at the driver. This patch changes the internals in a way that, at the driver, only a v4l2_tvnorm (a 64 bit integer) should be filled, with all supported tvnorms. videodev will dynamically generate the proper API array based on supported standards.

video_ioctl2 handler provides V4L2 API parsing. Using it makes the driver simpler, and isolates API parsing. This allows future reusage of driver controls using other ways, like sysfs and/or procfs and increases isolation of driver-specific handling from the generic common ioctl processing. Signed-off-by: -

With the previous patch, mplayer started but was polling the video device forever without any video actually coming out. Further analysis showed that it does a VIDIOC_S_FMT with width and height set to -1 (!!!). The code handling this only cares that both are lower than the minimum range allowed so it ends up setting the size to 19x17 (!!) This pretty much breaks the encoder here. Even if this breakage is yet another (TM) result of my setup, setting the size to 19x17 by default would surprise most users IMHO. So, special case for -1 and interpret this to be a request for the default size, please. Users can then set their favorite size both through mplayer and through sysfs. With this patch, mplayer finally works in pvr:// mode (not that we really gain anything over operating it through sysfs with lirc, sometime I might actually get off my lazy a** and contribute this setup too) Signed-off-by:

This should allow mplayer pvr:// to start. The trick is that no matter what actual input we use under this "fake" one, it will be able to do stereo :-) Signed-off-by:

Audio mode changes are not private to the audio chip - other I2C modules need to see this as well. And since the command in question is VIDIOC_S_TUNER which is a standard v4l2 command, we really should be broadcasting it out. This change sets up a broadcast pathway for VIDIOC_S_TUNER and also eliminates the now redundant code from the audio chip handler. This fix enables stereo reception for the FM radio Signed-off-by:

Attempts to enumerate or operate on a group of EXT_CTRLS where the group size is zero is OK; don't fail on such operations. At least one application uses this to probe for the existence of this API so let it succeed. Signed-off-by:

The automodeswitch control was a feature that enable automatic radio / tv switching based on the selected frequency. However since frequency ranges can overlap and also since apparently in some cases it's possible for the same frequency range to be both tv and radio in a specific region, then this feature can't safely work. So it's removed. Signed-off-by:

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.

Clean up and tighten logic involving stream configuration. This mainly involves changes to pvrusb2-v4l2.c, where we better clarify how we use the stream configuration enum and implement a cleaner means to control streaming for a given device node. Signed-off-by:

The default volume of 65535 is too high. Make is something smaller. Note that this _only_ changes the default value. Specifically, there are no scaling or other more intrusive changes here. I'm just sick of constantly having to reduce the volume every time I plug in and test the device! (And unfortunately we can't do a better fix like scaling the volume so that 65535 makes sense because doing so will screw up any app - like MythTV - which expects the old scaling.) Too bad V4L controls don't have better defined ranges. Signed-off-by:

Trying to temporarily check that the stream is not claimed during open of the radio device is at best a race condition. What's to stop another app from claiming the stream anyway the instant after the check is done? The implementation for this was dicey anyway. So it's removed. The only "price" for this is that if /dev/radioX is opened while streaming video, then the video stream is just going to switch to radio mode anyway. If a user does this, he gets what he expects...

Frequency units in V4L2 are apparently different when in radio mode compared to tv mode. Why? Who knows. This change adapts the driver appropriately - so that internally we always only deal in Hz and don't have to muck with craziness like this. Signed-off-by:

We can't allocate v4l device structures in a block, since the v4l core governs when each device actually gets freed. This bug was introduced as part of the core radio implementation. Fix it. Signed-off-by:
