What is YUV NV12?

What is YUV NV12?

NV12. A format in which all Y samples are found first in memory as an array of unsigned char with an even number of lines (possibly with a larger stride for memory alignment). This is followed immediately by an array of unsigned char containing interleaved Cb and Cr samples.

What is YV12 format?

YV12 is exactly like I420, but the order of the U and V planes is reversed. In the name, “YV” refers to the plane order: Y, then V (then U). “12” refers to the pixel depth: 12-bits per pixel as for I420.

What’s better 2160p YUV420 or RGB?

2160p – YUV420 allows the console to connect to older 4K displays that don’t support higher HDMI 2.0 bandwidth. 2160p – RGB doubles the bandwidth requirement, so this is what newer 4K televisions will support.

What is a YUV cable?

A YUV cable is also called a “color differential cable“ and consists of three separate unbalanced 75 Ω lines. It is commonly used for connections in video engineering (e.g. on “progressive scan beamers“) and for linking the DVD player.

What is a YUV image?

YUV is a color model typically used as part of a color image pipeline. It encodes a color image or video taking human perception into account, allowing reduced bandwidth for chrominance components, compared to a “direct” RGB-representation.

What resolution is best for PS4?

The PS4 Pro supports 4K output, as opposed to the standard PS4’s Full HD 1080p resolution.

What is the difference between YV12 and iyuv?

IYUV The same as YV12, except for swapping the order of the Cb and Cr planes. NV12 A format in which all Y samples are found first in memory as an array of unsigned char with an even number of lines (possibly with a larger stride for memory alignment).

How many Y samples are there in nv12?

In NV12, chroma planes (blue and red) are subsampled in both the horizontal and vertical dimensions by a factor of 2. For a 2×2 group of pixels, you have 4 Y samples and 1 U and 1 V sample.

What is the difference between nv12 and NV21?

NV12 is the preferred 4:2:0 pixel format. NV21 The same as NV12, except that Cb and Cr samples are swapped so that the chroma array of unsigned char would have Cr followed by Cb for each sample (such that if addressed as a little-endian WORD type, Cr would be in the least significant bits and Cb would be in the most significant bits).

What is the difference between YV12 and CB and CR planes?

The same as YV12, except that the stride of the Cb and Cr planes is the same as the stride in the Y plane. Also, the Cb and Cr planes must fall on memory boundaries that are a multiple of 16 lines. The following code examples show calculations for the Cb and Cr planes.
