The v4l2_ctrl_query_fill_std() function wasn't one the best idea I ever had.
It doesn't add anything valuable that cannot be expressed equally well with
v4l2_ctrl_query_fill and only adds overhead.Replace it with v4l2_ctrl_query_fill() everywhere it is used and remove it
from v4l2_common.c.Signed-off-by: Hans Verkuil

Control arrays as are used with v4l2_ctrl_next must be sorted from

The cx2341x_mpeg_ctrls array must be ordered by control ID. I know that
this is bad design, but for now I will just fix this bug and revisit it
when all drivers have moved to v4l2_device/v4l2_subdev, since that will
allow me to do greatly improve control handling.Signed-off-by: Hans Verkuil

Fix bugs in the cx18 AC3 control implementation that would have affected
ivtv and other drivers via the cx2341x module. Bring AC3 controls
behavior into comliance with V4L2 specification. Thanks to Hans Verkuil
for reviewing the previous patch and pointing out the problems.Reported-by: Hans Verkuil

Initial addition of controls to set AC-3 audio encoding for the CX23418 - it
does not work yet due to firmware or cx18 driver issues. This change affects
the common cx2341x and ivtv modules due to shared structures and
common functions.Signed-off-by: Andy Walls

For several MPEG controls and the volume control the default as returned
by VIDIOC_QUERYCTRL was incorrect and did not match the actual initial
value.This is now fixed for cx18 and ivtv.

The driver should now pass the 'busy' state of the device to the cx2341x
module whenever controls are set or tried. -EBUSY will be returned if
the device is busy and the user attempts to modify certain 'dangerous'
controls. It concerns controls that change the audio or video
compression mode and bitrates.The cx88-blackbird and pvrusb2 drivers currently always pass '0' (not busy)
to the cx2341x, effectively keeping the old behavior for now.Signed-off-by: Hans Verkuil

The commands CX2341X_DEC_SET_AUDIO_OUTPUT, CX2341X_DEC_SET_AV_DELAY and
CX2341X_ENC_SET_3_2_PULLDOWN are not implemented in the Conexant firmware.
So these commands are removed. This also means that the V4L2_CID_MPEG_VIDEO_PULLDOWN
control in cx2341x.c and pvrusb2-hdw.c is removed.Signed-off-by: Hans Verkuil

The temporal filter is forced off when scaling. The VIDIOC_LOG_STATUS
handler still showed the old temporal filter. It is now consistent with
the real temporal filter value.Signed-off-by: Hans Verkuil

Adjust temporal filter if necessary. The problem with the temporal
filter is that it works well with full resolution capturing, but
not when the capture window is scaled (the filter introduces
a ghosting effect). So if the capture window changed, and there is
no updated filter value, then the filter is set depending on whether
the new window is full resolution or not.
For full resolution a setting of 8 really improves the video
quality, especially if the original video quality is suboptimal.
Also report VBI Format in VIDIOC_LOG_STATUS, it was missing.Signed-off-by: Hans Verkuil

V4L2_CID_MPEG_STREAM_VBI_FMT controls if and how VBI data is embedded in
an MPEG stream. Currently only one format is supported: the format designed

CX2341X port was always set to 'memory', but 'streaming' is also possible
ivtv uses the memory (DMA) interface with the CX2341X, while pvrusb2 and
cx88-blackbird use the streaming interface. This setting is now selectable
by the driver.Signed-off-by: Hans Verkuil
