+ <title>Digital Video (DV) Timings</title>
+ <para>
+ The video standards discussed so far has been dealing with Analog TV and the
+corresponding video timings. Today there are many more different hardware interfaces
+such as High Definition TV interfaces (HDMI), VGA, DVI connectors etc., that carry
+video signals and there is a need to extend the API to select the video timings
+for these interfaces. Since it is not possible to extend the &v4l2-std-id; due to
+the limited bits available, a new set of IOCTLs is added to set/get video timings at
+the input and output: </para><itemizedlist>
+ <listitem>
+ <para>DV Presets: Digital Video (DV) presets. These are IDs representing a
+video timing at the input/output. Presets are pre-defined timings implemented
+by the hardware according to video standards. A __u32 data type is used to represent
+a preset unlike the bit mask that is used in &v4l2-std-id; allowing future extensions
+to support as many different presets as needed.</para>
+ </listitem>
+ <listitem>
+ <para>Custom DV Timings: This will allow applications to define more detailed
+custom video timings for the interface. This includes parameters such as width, height,
+polarities, frontporch, backporch etc.
+ </para>
+ </listitem>
+ </itemizedlist>
+ <para>To enumerate and query the attributes of DV presets supported by a device,
+applications use the &VIDIOC-ENUM-DV-PRESETS; ioctl. To get the current DV preset,
+applications use the &VIDIOC-G-DV-PRESET; ioctl and to set a preset they use the
+&VIDIOC-S-DV-PRESET; ioctl.</para>
+ <para>To set custom DV timings for the device, applications use the
+&VIDIOC-S-DV-TIMINGS; ioctl and to get current custom DV timings they use the
+&VIDIOC-G-DV-TIMINGS; ioctl.</para>
+ <para>Applications can make use of the <xref linkend="input-capabilities" /> and
+<xref linkend="output-capabilities"/> flags to decide what ioctls are available to set the
+video timings for the device.</para>

+ <para>The hardware may be able to detect the current DV preset
+automatically, similar to sensing the video standard. To do so, applications

+returned in the preset field of &v4l2-dv-preset;. When detection is not
+possible or fails, the value V4L2_DV_INVALID is returned.</para>

+ Cropping and Scaling algorithm, used in the sh_mobile_ceu_camera driver
+ =======================================================================

+
+sensor scales: horizontal and vertical scales, configured by the sensor driver
+host scales: -"- host driver
+combined scales: sensor_scale * host_scale

+Produced by user requests:
+
+S_CROP(left / top = (5) - (1), width / height = (5') - (5))
+S_FMT(width / height = (6') - (6))
+
+Here:
+
+(1) to (1') - whole max width or height
+(1) to (2) - sensor cropped left or top
+(2) to (2') - sensor cropped width or height
+(3) to (3') - sensor scale
+(3) to (4) - CEU cropped left or top
+(4) to (4') - CEU cropped width or height
+(5) to (5') - reverse sensor scale applied to CEU cropped width or height
+(2) to (5) - reverse sensor scale applied to CEU cropped left or top
+(6) to (6') - CEU scale - user window
+
+
+S_FMT
+-----
+
+Do not touch input rectangle - it is already optimal.
+
+1. Calculate current sensor scales:
+
+ scale_s = ((3') - (3)) / ((2') - (2))
+
+2. Calculate "effective" input crop (sensor subwindow) - CEU crop scaled back at
+current sensor scales onto input window - this is user S_CROP:
+
+ width_u = (5') - (5) = ((4') - (4)) * scale_s
+
+3. Calculate new combined scales from "effective" input window to requested user
+window:
+
+ scale_comb = width_u / ((6') - (6))
+
+4. Calculate sensor output window by applying combined scales to real input
+window:
+
+ width_s_out = ((2') - (2)) / scale_comb
+
+5. Apply iterative sensor S_FMT for sensor output window.
+
+ subdev->video_ops->s_fmt(.width = width_s_out)
+
+6. Retrieve sensor output window (g_fmt)
+
+7. Calculate new sensor scales:
+
+ scale_s_new = ((3')_new - (3)_new) / ((2') - (2))
+
+8. Calculate new CEU crop - apply sensor scales to previously calculated
+"effective" crop:
+
+ width_ceu = (4')_new - (4)_new = width_u / scale_s_new
+ left_ceu = (4)_new - (3)_new = ((5) - (2)) / scale_s_new
+
+9. Use CEU cropping to crop to the new window:
+
+ ceu_crop(.width = width_ceu, .left = left_ceu)
+
+10. Use CEU scaling to scale to the requested user window:
+
+ scale_ceu = width_ceu / width
+
+
+S_CROP
+------
+
+If old scale applied to new crop is invalid produce nearest new scale possible
+
+1. Calculate current combined scales.
+
+ scale_comb = (((4') - (4)) / ((6') - (6))) * (((2') - (2)) / ((3') - (3)))
+
+2. Apply iterative sensor S_CROP for new input window.
+
+3. If old combined scales applied to new crop produce an impossible user window,
+adjust scales to produce nearest possible window.
+
+ width_u_out = ((5') - (5)) / scale_comb
+
+ if (width_u_out > max)
+ scale_comb = ((5') - (5)) / max;
+ else if (width_u_out < min)
+ scale_comb = ((5') - (5)) / min;
+
+4. Issue G_CROP to retrieve actual input window.
+
+5. Using actual input window and calculated combined scales calculate sensor
+target output window.
+
+ width_s_out = ((3') - (3)) = ((2') - (2)) / scale_comb
+
+6. Apply iterative S_FMT for new sensor target output window.
+
+7. Issue G_FMT to retrieve the actual sensor output window.
+
+8. Calculate sensor scales.
+
+ scale_s = ((3') - (3)) / ((2') - (2))
+
+9. Calculate sensor output subwindow to be cropped on CEU by applying sensor
+scales to the requested window.
+
+ width_ceu = ((5') - (5)) / scale_s
+
+10. Use CEU cropping for above calculated window.
+
+11. Calculate CEU scales from sensor scales from results of (10) and user window
+from (3)
+
+ scale_ceu = calc_scale(((5') - (5)), &width_u_out)
+
+12. Apply CEU scales.

There are a few useful helper functions:
+- file/video_device private data
+
You can set/get driver private data in the video_device struct using:
void *video_get_drvdata(struct video_device *vdev);
returns the video_device belonging to the file struct.
-The final helper function combines video_get_drvdata with
-video_devdata:
+The video_drvdata function combines video_get_drvdata with video_devdata:
void *video_drvdata(struct file *file);
struct v4l2_device *v4l2_dev = vdev->v4l2_dev;
+- Device node name
+
+The video_device node kernel name can be retrieved using
+
+const char *video_device_node_name(struct video_device *vdev);
+
+The name is used as a hint by userspace tools such as udev. The function
+should be used where possible instead of accessing the video_device::num and
+video_device::minor fields.
