FOURCC Codes For 10-Bit and 16-Bit YUV

The FOURCC codes for the formats described here use the following convention:

  • If the format is planar, the first character in the FOURCC code is 'P'. If the format is packed, the first character is 'Y'.

  • The second character in the FOURCC code is determined by the chroma sampling, as shown in the following table.

    Chroma sampling FOURCC code letter
    4:4:4 '4'
    4:2:2 '2'
    4:2:1 '1'
    4:2:0 '0'

     

  • The final two characters in the FOURCC indicate the number of bits per channel, either '16' for 16 bits or '10' for 10 bits.

Using this scheme, the following FOURCC codes have been defined. No 4:2:1 formats for 10-bit or 16-bit YUV have been defined at this time.

FOURCC Description
P016 Planar, 4:2:0, 16-bit.
P010 Planar, 4:2:0, 10-bit.
P216 Planar, 4:2:2, 16-bit.
P210 Planar, 4:2:2, 10-bit.
Y216 Packed, 4:2:2, 16-bit.
Y210 Packed, 4:2:2, 10-bit.
Y416 Packed, 4:4:4, 16-bit
Y410 Packed, 4:4:4, 10-bit.

 

Subtype GUIDs have also been defined from these FOURCCs; see Video Subtype GUIDs.

Surface Definitions

This section describes the memory layout of each format. In the descriptions that follow, the term WORD refers to a little-endian 16-bit value, and the term DWORD refers to a little-endian 32-bit value.

4:2:0 Formats

Two 4:2:0 formats are defined, with the FOURCC codes P016 and P010. They share the same memory layout, but P016 uses 16 bits per channel and P010 uses 10 bits per channel.

P016 and P010

In these two formats, all Y samples appear first in memory as an array of WORDs with an even number of lines. The surface stride can be larger than the width of the Y plane. This array is followed immediately by an array of WORDs that contains interleaved U and V samples, as shown in the following diagram.

Diagram showing P016 and P010 pixel layout

If the combined U-V array is addressed as an array of DWORDs, the least significant word (LSW) contains the U value and the most significant word (MSW) contains the V value. The stride of the combined U-V plane is equal to the stride of the Y plane. The U-V plane has half as many lines as the Y plane.

These two formats are the preferred 4:2:0 planar pixel formats for higher precision YUV representations. They are expected to be an intermediate-term requirement for DirectX Video Acceleration (DXVA) accelerators that support 10-bit or 16-bit 4:2:0 video.

4:2:2 Formats

Four 4:2:2 formats are defined, two planar and two packed. They have the following FOURCC codes:

  • P216
  • P210
  • Y216
  • Y210

P216 and P210

In these two planar formats, all Y samples appear first in memory as an array of WORDs with an even number of lines. The surface stride can be larger than the width of the Y plane. This array is followed immediately by an array of WORDs that contains interleaved U and V samples, as shown in the following diagram.

Diagram showing P216 and P210 pixel layout

If the combined U-V array is addressed as an array of DWORDs, the LSW contains the U value and the MSW contains the V value. The stride of the combined U-V plane is equal to the stride of the Y plane. The U-V plane has the same number of lines as the Y plane.

These two formats are the preferred 4:2:2 planar pixel formats for higher precision YUV representations. They are expected to be an intermediate-term requirement for DirectX Video Acceleration (DXVA) accelerators that support 10-bit or 16-bit 4:2:2 video.

Y216 and Y210

In these two packed formats, each pair of pixels is stored as an array of four WORDs, as shown in the following illustration.

Diagram showing Y216 and Y210 pixel layout.

The first WORD in the array contains the first Y sample in the pair, the second WORD contains the U sample, the third WORD contains the second Y sample, and the fourth WORD contains the V sample.

Y210 is identical to Y216 except that each sample contains only 10 bits of significant data. The least significant 6 bits are set to zero, as described previously.

4:4:4 Formats

Two 4:4:4 formats are defined, with the FOURCC codes Y410 and Y416. Both are packed formats.

Y410

This format is a packed 10-bit representation that includes 2 bits of alpha. Each pixel is encoded as a single DWORD with the memory layout shown in the following diagram.

Diagram showing Y410 pixel layout.

Bits 0-9 contain the U sample, bits 10-19 contain the Y sample, bits 20-29 contain the V sample, and bits 30-31 contain the alpha value. To indicate that a pixel is fully opaque, an application must set the two alpha bits equal to 0x03.

Y416

This format is a packed 16-bit representation that includes 16 bits of alpha. Each pixel is encoded as a pair of DWORDs, as shown in the following illustration.

Diagram showing Y416 pixel layout.

Bits 0-15 contain the U sample, bits 16-31 contain the Y sample, bits 32-47 contain the V sample, and bits 48-63 contain the alpha value.

To indicate that a pixel is fully opaque, an application must set the two alpha bits equal to 0xFFFF. This format is intended primarily as an intermediate format during image processing to avoid the accumulation of errors.

Preferred YUV Formats

The following table lists the preferred YUV formats, including 8-bit formats.

Format Chroma sampling Packed or planar Bits per channel
AYUV 4:4:4 Packed 8
Y410 4:4:4 Packed 10
Y416 4:4:4 Packed 16
AI44 4:4:4 Packed Palettized
YUY2 4:2:2 Packed 8
Y210 4:2:2 Packed 10
Y216 4:2:2 Packed 16
P210 4:2:2 Planar 10
P216 4:2:2 Planar 16
NV12 4:2:0 Planar 8
P010 4:2:0 Planar 10
P016 4:2:0 Planar 16
NV11 4:1:1 Planar 8

 

It is recommended that if an object supports a given bit depth and chroma sampling scheme, it should support the corresponding YUV formats listed in this table. (Objects might support additional formats not listed here.)

Remarks

For palettized formats, the color of each pixel is specified as an index into a palette. The palette must be included in the format block, following the BITMAPINFOHEADER structure. For non-palettized formats, the color of each pixel is specified directly; the memory layout depends on the bit depth:

  • RGB 555 uses the following memory layout:
    C++
     
    High-order byte:    Low-order byte: 
X R R R R R G G     G G G B B B B B 

X = Don't care, R = Red, G = Green, B = Blue
  • RGB 565 uses the following memory layout:
    C++
     
    High-order byte:    Low-order byte: 
R R R R R G G G     G G G B B B B B
  • For RGB 24, every pixel is an RGBTRIPLE. Each color is one byte, with a value from 0 to 255, inclusive. The memory layout is:
    Byte 0 1 2
    Value Blue Green Red

     

  • For RGB 32, every pixel is an RGBQUAD. Each color is one byte, with a value from 0 to 255, inclusive. The memory layout is:
    Byte 0 1 2 3
    Value Blue Green Red Alpha or Don't Care

     

    If the subtype is MEDIASUBTYPE_ARGB32, byte 3 contains a value for the alpha channel. If the subtype is MEDIASUBTYPE_RGB32, byte 3 should be ignored.

  • A2R10G10B10 uses the following layout:
    Bit 0 - 9 10 - 19 20 - 29 30 - 31
    Value Blue Green Red Alpha

     

  • A2B10G10R10 uses the following layout:
    Bit 0 - 9 10 - 19 20 - 29 30 - 31
    Value Red Green Blue Alpha

2. Image Formats

The V4L2 API was primarily designed for devices exchanging image data with applications. The struct v4l2_pix_format and struct v4l2_pix_format_mplane structures define the format and layout of an image in memory. The former is used with the single-planar API, while the latter is used with the multi-planar version (see Single- and multi-planar APIs). Image formats are negotiated with the VIDIOC_S_FMT ioctl. (The explanations here focus on video capturing and output, for overlay frame buffer formats see also VIDIOC_G_FBUF.)
