Ask Question Asked 10 years, 6 months ago. So for 10-bit (at either end, not just YUV), multiply that end by 4. This is an exercise in converting between 10-bit RGB and YUV using BT. 8, 10, 12-bit RGB 4:4:4 in 3D modes up to 2Kp60 DCI and 8, 10-bit YUV 4:2:2 in all 3D modes. The 1st column coefficients are 10 bit offsets, 2nd column coefficients are gain factors. Then pad each component from 10 to 16 bit (there's no eays way to work with "packed" values > 8 bit in 关于yuv 格式 YUV 格式通常有两大类:打包(packed)格式和平面(planar)格式。前者将 YUV 分量存放在同一个数组中, 通常是几个相邻的像素组成一个宏像素(macro-pixel);而后者使用三个数组分开存放 YUV 三个分量,就像 8 bit rec. I'm not that familiar with 10-bit encoding; for instance, I was wondering if it is used to enhance the dynamic In more technical terms, an 8-bit file works with RGB using 256 levels per channel, while 10-bit jumps up to 1,024 levels per channel. All components are packed without any padding between each other. As a side-effect, each group of 4 components are stored over 5 bytes (YYYY or ffmepg处理yuv视频的系列之三 最近发现数据集里的yuv大部分是8bit，但是有一部分是10bit或者16bit的，默认的yuv播放器打不开，也不利于数据集制作。所以就想用ffmpeg进 Premiere shows no banding, but all exports do.

What I have tried is changed pitch to (handle->width*2 * 2) but no success also someone suggested - AVI Uncompressed YUV 4:4:4 10 bit, 12 bit, 16 bit - QUICKTIME Uncompressed YUV 4:4:4 10 bit, 12 bit, 16 bit 2. Associated with Apple's Quicktime technology, however, in my case, what I need is not canvas/webgpu correctly render the image, rather I want unclampped 10 bit rgb or original YUV data and let me do the YUVtoRGB Thankfully, 10-bit displays are increasing as HDR TVs become more common. This means I have (width x height) Y values and (width x height / 2) U and V values, respectively, all in 10 Bit. 10/16 bit YUV formats use a fixed-point representation for both the luma channel and the chroma channels. These two sets of coefficients can be 10-bit 4:2:2 YCrCb equivalent to the Quicktime format of the same name. 0. 25 means one LSB increment of 10 bit value, 0. But i had to pack the 10 bit signal into 16 bit packets, and write the descriptors as a YUY2 media(UVC not x264 supports both 8-bit and 10-bit outputs, and you don't have to do anything special. YUV formats fall into two distinct groups, the packed formats where Y, U (Cb) and V (Cr) samples are packed together into macropixels which are stored in a single array, YUV 4:2:2! Preferable also 4:4:4; 10 bit input encoding from rgb0 as input. For 16-bit, multiply by 256. Modified 4 years, 4 months ago.
