Sets the alpha color component. When a capture device (or capture
queue of a mem-to-mem device) produces a frame format that includes
an alpha component (e.g.
- :ref:`packed RGB image formats <rgb-formats>`) and the alpha value
+ :ref:`packed RGB image formats <pixfmt-rgb>`) and the alpha value
is not defined by the device or the mem-to-mem input data this
control lets you select the alpha component value of all pixels.

-Description
-===========
-
-These formats are designed to match the pixel formats of typical PC
-graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel.
-These are all packed-pixel formats, meaning all the data for a pixel lie
-next to each other in memory.

-.. note:: Bit 7 is the most significant bit.
-
-The usage and value of the alpha bits (a) in the ARGB and ABGR formats
-(collectively referred to as alpha formats) depend on the device type
-and hardware operation. :ref:`Capture <capture>` devices (including
-capture queues of mem-to-mem devices) fill the alpha component in
-memory. When the device outputs an alpha channel the alpha component
-will have a meaningful value. Otherwise, when the device doesn't output
-an alpha channel but can set the alpha bit to a user-configurable value,
-the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
-is used to specify that alpha value, and the alpha component of all
-pixels will be set to the value specified by that control. Otherwise a
-corresponding format without an alpha component (XRGB or XBGR) must be
-used instead of an alpha format.
-
-:ref:`Output <output>` devices (including output queues of mem-to-mem
-devices and :ref:`video output overlay <osd>` devices) read the alpha
-component from memory. When the device processes the alpha channel the
-alpha component must be filled with meaningful values by applications.
-Otherwise a corresponding format without an alpha component (XRGB or
-XBGR) must be used instead of an alpha format.
-
-The XRGB and XBGR formats contain undefined bits (-). Applications,
-devices and drivers must ignore those bits, for both
-:ref:`capture` and :ref:`output` devices.

+These formats are designed to match the pixel formats of typical PC
+graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel.
+These are all packed-pixel formats, meaning all the data for a pixel lie
+next to each other in memory.

+.. note:: Bit 7 is the most significant bit.
+
+The usage and value of the alpha bits (a) in the ARGB and ABGR formats
+(collectively referred to as alpha formats) depend on the device type
+and hardware operation. :ref:`Capture <capture>` devices (including
+capture queues of mem-to-mem devices) fill the alpha component in
+memory. When the device outputs an alpha channel the alpha component
+will have a meaningful value. Otherwise, when the device doesn't output
+an alpha channel but can set the alpha bit to a user-configurable value,
+the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
+is used to specify that alpha value, and the alpha component of all
+pixels will be set to the value specified by that control. Otherwise a
+corresponding format without an alpha component (XRGB or XBGR) must be
+used instead of an alpha format.
+
+:ref:`Output <output>` devices (including output queues of mem-to-mem
+devices and :ref:`video output overlay <osd>` devices) read the alpha
+component from memory. When the device processes the alpha channel the
+alpha component must be filled with meaningful values by applications.
+Otherwise a corresponding format without an alpha component (XRGB or
+XBGR) must be used instead of an alpha format.
+
+The XRGB and XBGR formats contain undefined bits (-). Applications,
+devices and drivers must ignore those bits, for both
+:ref:`capture` and :ref:`output` devices.

+A test utility to determine which RGB formats a driver actually supports
+is available from the LinuxTV v4l-dvb repository. See
+`https://linuxtv.org/repo/ <https://linuxtv.org/repo/>`__ for access
+instructions.
- The pixel format or type of compression, set by the application.
This is a little endian
:ref:`four character code <v4l2-fourcc>`. V4L2 defines standard
- RGB formats in :ref:`rgb-formats`, YUV formats in
+ RGB formats in :ref:`pixfmt-rgb`, YUV formats in
:ref:`yuv-formats`, and reserved codes in
