This should not be confused with the V4L2 pixel formats -that describe, using four character codes, image formats as stored in -memory. - -While there is a relationship between image formats on busses and image -formats in memory (a raw Bayer image won't be magically converted to -JPEG just by storing it to memory), there is no one-to-one -correspondance between them. - - -Packed RGB Formats -^^^^^^^^^^^^^^^^^^ - -Those formats transfer pixel data as red, green and blue components. The -format code is made of the following information. - -- The red, green and blue components order code, as encoded in a pixel - sample. Possible values are RGB and BGR. - -- The number of bits per component, for each component. The values can - be different for all components. Common values are 555 and 565. - -- The number of bus samples per pixel. Pixels that are wider than the - bus width must be transferred in multiple samples. Common values are - 1 and 2. - -- The bus width. - -- For formats where the total number of bits per pixel is smaller than - the number of bus samples per pixel times the bus width, a padding - value stating if the bytes are padded in their most high order bits - (PADHI) or low order bits (PADLO). A "C" prefix is used for - component-wise padding in the most high order bits (CPADHI) or low - order bits (CPADLO) of each separate component. - -- For formats where the number of bus samples per pixel is larger than - 1, an endianness value stating if the pixel is transferred MSB first - (BE) or LSB first (LE). - -For instance, a format where pixels are encoded as 5-bits red, 5-bits -green and 5-bit blue values padded on the high bit, transferred as 2 -8-bit samples per pixel with the most significant bits (padding, red and -half of the green value) transferred first will be named -``MEDIA_BUS_FMT_RGB555_2X8_PADHI_BE``. - -The following tables list existing packed RGB formats. - -.. HACK: ideally, we would be using adjustbox here. However, Sphinx -.. is a very bad behaviored guy: if the table has more than 30 cols, -.. it switches to long table, and there's no way to override it. - - -.. tabularcolumns:: |p{4.0cm}|p{0.7cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}| -

- -Packed YUV Formats -^^^^^^^^^^^^^^^^^^ - -Those data formats transfer pixel data as (possibly downsampled) Y, U -and V components. Some formats include dummy bits in some of their -samples and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma) -formats. One cannot rely on the values of these dummy bits as those are -undefined. - -The format code is made of the following information. - -- The Y, U and V components order code, as transferred on the bus. - Possible values are YUYV, UYVY, YVYU and VYUY for formats with no - dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC - formats. - -- The number of bits per pixel component. All components are - transferred on the same number of bits. Common values are 8, 10 and - 12. - -- The number of bus samples per pixel. Pixels that are wider than the - bus width must be transferred in multiple samples. Common values are - 1, 1.5 (encoded as 1_5) and 2. - -- The bus width. When the bus width is larger than the number of bits - per pixel component, several components are packed in a single bus - sample. The components are ordered as specified by the order code, - with components on the left of the code transferred in the high order - bits. Common values are 8 and 16. - -For instance, a format where pixels are encoded as 8-bit YUV values -downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in -the U, Y, V, Y order will be named ``MEDIA_BUS_FMT_UYVY8_2X8``. - -:ref:`v4l2-mbus-pixelcode-yuv8` lists existing packed YUV formats and -describes the organization of each pixel data in each sample. When a -format pattern is split across multiple samples each of the samples in -the pattern is described. - -The role of each bit transferred over the bus is identified by one of -the following codes. - -- y\ :sub:`x` for luma component bit number x - -- u\ :sub:`x` for blue chroma component bit number x - -- v\ :sub:`x` for red chroma component bit number x - -- a\ :sub:`x` for alpha component bit number x - -- for non-available bits (for positions higher than the bus width) - -- d for dummy bits - -..

This should not be confused with the V4L2 pixel formats +that describe, using four character codes, image formats as stored in +memory. - - u\ :sub:`11` +While there is a relationship between image formats on busses and image +formats in memory (a raw Bayer image won't be magically converted to +JPEG just by storing it to memory), there is no one-to-one +correspondance between them. - - u\ :sub:`10` - - u\ :sub:`9` +Packed RGB Formats +^^^^^^^^^^^^^^^^^^ - - u\ :sub:`8` +Those formats transfer pixel data as red, green and blue components. The +format code is made of the following information. - - u\ :sub:`7` +- The red, green and blue components order code, as encoded in a pixel + sample. Possible values are RGB and BGR. - - u\ :sub:`6` +- The number of bits per component, for each component. The values can + be different for all components. Common values are 555 and 565. - - u\ :sub:`5` +- The number of bus samples per pixel. Pixels that are wider than the + bus width must be transferred in multiple samples. Common values are + 1 and 2. - - u\ :sub:`4` +- The bus width. - - u\ :sub:`3` +- For formats where the total number of bits per pixel is smaller than + the number of bus samples per pixel times the bus width, a padding + value stating if the bytes are padded in their most high order bits + (PADHI) or low order bits (PADLO). A "C" prefix is used for + component-wise padding in the most high order bits (CPADHI) or low + order bits (CPADLO) of each separate component. - - u\ :sub:`2` +- For formats where the number of bus samples per pixel is larger than + 1, an endianness value stating if the pixel is transferred MSB first + (BE) or LSB first (LE). - - u\ :sub:`1` +For instance, a format where pixels are encoded as 5-bits red, 5-bits +green and 5-bit blue values padded on the high bit, transferred as 2 +8-bit samples per pixel with the most significant bits (padding, red and +half of the green value) transferred first will be named +``MEDIA_BUS_FMT_RGB555_2X8_PADHI_BE``. - - u\ :sub:`0` +The following tables list existing packed RGB formats. - - .. _MEDIA-BUS-FMT-YUV10-1X30: +..

- y\ :sub:`7` - - y\ :sub:`6` +Packed YUV Formats +^^^^^^^^^^^^^^^^^^ - - y\ :sub:`5` +Those data formats transfer pixel data as (possibly downsampled) Y, U +and V components. Some formats include dummy bits in some of their +samples and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma) +formats. One cannot rely on the values of these dummy bits as those are +undefined. - - y\ :sub:`4` +The format code is made of the following information. - - y\ :sub:`3` +- The Y, U and V components order code, as transferred on the bus. + Possible values are YUYV, UYVY, YVYU and VYUY for formats with no + dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC + formats. - - y\ :sub:`2` +- The number of bits per pixel component. All components are + transferred on the same number of bits. Common values are 8, 10 and + 12. - - y\ :sub:`1` +- The number of bus samples per pixel. Pixels that are wider than the + bus width must be transferred in multiple samples. Common values are + 1, 1.5 (encoded as 1_5) and 2. - - y\ :sub:`0` +- The bus width. When the bus width is larger than the number of bits + per pixel component, several components are packed in a single bus + sample. The components are ordered as specified by the order code, + with components on the left of the code transferred in the high order + bits. Common values are 8 and 16. - - u\ :sub:`7` +For instance, a format where pixels are encoded as 8-bit YUV values +downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in +the U, Y, V, Y order will be named ``MEDIA_BUS_FMT_UYVY8_2X8``. - - u\ :sub:`6` +:ref:`v4l2-mbus-pixelcode-yuv8` lists existing packed YUV formats and +describes the organization of each pixel data in each sample. When a +format pattern is split across multiple samples each of the samples in +the pattern is described. - - u\ :sub:`5` +The role of each bit transferred over the bus is identified by one of +the following codes. - - u\ :sub:`4` +- y\ :sub:`x` for luma component bit number x - - u\ :sub:`3` +- u\ :sub:`x` for blue chroma component bit number x - - u\ :sub:`2` +- v\ :sub:`x` for red chroma component bit number x - - u\ :sub:`1` +- a\ :sub:`x` for alpha component bit number x - - u\ :sub:`0` +- for non-available bits (for positions higher than the bus width) - - v\ :sub:`7` +- d for dummy bits - - v\ :sub:`6` +..

They will send a ``V4L2_EVENT_EOS`` event when the + last frame has been decoded and all frames are ready to be + dequeued and will set the ``V4L2_BUF_FLAG_LAST`` buffer flag on + the last buffer of the capture queue to indicate there will be no + new buffers produced to dequeue. This buffer may be empty, + indicated by the driver setting the ``bytesused`` field to 0. Once + the ``V4L2_BUF_FLAG_LAST`` flag was set, the + :ref:`VIDIOC_DQBUF ` ioctl will not block anymore, + but return an ``EPIPE`` error code. If + ``V4L2_DEC_CMD_STOP_IMMEDIATELY`` is set, then the decoder stops + immediately (ignoring the ``pts`` value), otherwise it will keep + decoding until timestamp >= pts or until the last of the pending + data from its internal buffers was decoded. + * - ``V4L2_DEC_CMD_PAUSE`` + - 2 + - Pause the decoder. When the decoder has not been started yet, the + driver will return an ``EPERM`` error code. When the decoder is + already paused, this command does nothing. This command has one + flag: if ``V4L2_DEC_CMD_PAUSE_TO_BLACK`` is set, then set the + decoder output to black when paused. + * - ``V4L2_DEC_CMD_RESUME`` + - 3 + - Resume decoding after a PAUSE command. When the decoder has not + been started yet, the driver will return an ``EPERM`` error code. When + the decoder is already running, this command does nothing. No + flags are defined for this command.

This is a read-only flag, + applications must not set this. + * - ``V4L2_DV_FL_CAN_REDUCE_FPS`` + - CEA-861 specific: set for CEA-861 formats with a framerate that is + a multiple of six. These formats can be optionally played at 1 / + 1.001 speed to be compatible with 60 Hz based standards such as + NTSC and PAL-M that use a framerate of 29.97 frames per second. If + the transmitter can't generate such frequencies, then the flag + will also be cleared. This is a read-only flag, applications must + not set this. + * - ``V4L2_DV_FL_REDUCED_FPS`` + - CEA-861 specific: only valid for video transmitters, the flag is + cleared by receivers. It is also only valid for formats with the + ``V4L2_DV_FL_CAN_REDUCE_FPS`` flag set, for other formats the + flag will be cleared by the driver. If the application sets this + flag, then the pixelclock used to set up the transmitter is + divided by 1.001 to make it compatible with NTSC framerates. If + the transmitter can't generate such frequencies, then the flag + will also be cleared. + * - ``V4L2_DV_FL_HALF_LINE`` + - Specific to interlaced formats: if set, then the vertical + frontporch of field 1 (aka the odd field) is really one half-line + longer and the vertical backporch of field 2 (aka the even field) + is really one half-line shorter, so each field has exactly the + same number of half-lines. Whether half-lines can be detected or + used depends on the hardware. + * - ``V4L2_DV_FL_IS_CE_VIDEO`` + - If set, then this is a Consumer Electronics (CE) video format. + Such formats differ from other formats (commonly called IT + formats) in that if R'G'B' encoding is used then by default the + R'G'B' values use limited range (i.e. 16-235) as opposed to full + range (i.e. 0-255). All formats defined in CEA-861 except for the + 640x480p59.94 format are CE formats. + * - ``V4L2_DV_FL_FIRST_FIELD_EXTRA_LINE`` + - Some formats like SMPTE-125M have an interlaced signal with a odd + total height.
