We can use YUYV for AFBC YUV 422 8-bit. There is a tolerance of +/- 1 between the unconverted RGB value and the post-conversion RGB value to allow for rounding errors. 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. G/Y is on one 8/10/12 bit channel. – The Direct2D part works because I 've successfully painted a HDR image when I have the ARGB as floats and also my color picker in HDR format works with trying float values. This smooth gradiant are often up at the sky in games, or dark areas in some places. In 8 bit RGB full black is 0,0,0 and full white is 255,255,255. yuv -c:v hevc_nvenc -pix_fmt yuv444p16le output. Is SDL support more than 8 bit depth pixel rendering ? Run ffmpeg -pix_fmts; Pick your favorite format with BIT_DEPTHS="16-16-16" or 16; Use -pix_fmt xxx output option in your command. So it is an 8-bit panel, that supports a full RGB range (hence why it's a monitor), but according to the marketing material, it has 10-bit (8-bit+FRC) "HDR". Inputting 8-bit to vvenc I get the colors as expected, all good. 601 and rec. This applies to RGB888 and YUV420 8-bit: . What I have tried is changed pitch to (handle->width*2 * 2) but no success also someone suggested to convert 10bit value to 8bit but I don't want to do that. Both can be read by VirtualDub FilterMod and I usually transcode after with VirtualDub filtermod or FFmpeg to 10 bit FFV1 yuv 4. 265/HEVC with x265 I got recommend do all in 10-bit, because x265 have any problem with picture on the 8-bit encode and with 10-bit it should have more effective compression, before few years. Notes: Here we use its “10 bit as 8 bit fractional” variant, so . 709 option. For example, libx264 spits out Supported pixel formats: yuv420p If the hardware only supports 8-bit output, you can either convert 10-bit YUV to 8-bit RGB, or convert 10-bit YUV to 10-bit RGB (rendering to a suitable texture attached to a framebuffer object) then convert 10-bit RGB to 8-bit RGB as a post-process (optionally using dithering or error-diffusion). I am trying to encode a 10-bit H. This page aims to explain the representation of color in a video setting while outlining the differences between common color models. 99615473]) - Float RGB output = [0. For YUV420 10 bit semiplanar format (also called as P010 as described in MSDN link) the data arrangement is as follows, Y (luma) is stored in a plane with each pixel taking a word (16 bit) U and V What is the file structure of a YUV 420 movie stream. So when convert RGB to YUV, results will be decimals, the rounding errors cause color banding artifact even they are both 8-bit, this problem can be addressed by using 10-bit YUV to "hold" 8-bit RGB and since many gfx cards support HEVC Main10 encoding and decoding today, the overhead will basically be zero (in terms of lossy encoding though, those 25% extra To convert 4:2:0 or 4:2:2 YUV to RGB, we recommend converting the YUV data to 4:4:4 YUV, and then converting from 4:4:4 YUV to RGB. 16-bit YUV 4:2:0 would thus give you 24-bit per pixel. YUV Convert also enables to save in HDR (High Dynamic Range) 10 bits (formats of 12 bits, 14 bits, 16 bits and floating numbers are possible upon request). 264/Intra-frame, 3840 x 2160, 23.

YUV 422 10-bit, 1-plane ----- There is no currently-defined YUV 422 10-bit format in drm_fourcc. mp4, it tells me that the underlying pixel format is actually yuv444p10le. The packed YUYV formats with more than 8 bits per component are stored as four 16-bit little-endian words. So much for monolithic thought processes in production, Bit depth of output clip. These formulas produce 8-bit results using coefficients that require no more than 8 bits of (unsigned) precision. The depth is 4*8+2*8+2*8 = 64 bits per 4 pixels, so 16 bits per pixel. YUYV, V422 or The number of bits to store 4 pixels in YUV 4:2:0 is: 4*8+8+8=48 bits i. An 8-bit YUV 4:2:0 video has 12 bits per pixel, because every 2x2 square of luma samples shares a pair of chroma samples. As @domdom says, convert the YUV values to RGB first. YUV Convert also supports other formats like RGBA and BGRA. Patched FFMS2 - import DNxHD, ProRes, and other 10-bit videos in their native format (4:2:2 and 4:4:4 are also supported), In the generic case, the first byte of payload data transmitted maps the LS bytes of the 32-bit memory word and the forth byte of payload data transmitted maps to the MS byte of the 32-bit word. I have YUV422 10-bits SDI from camera, and I need to accurately convert it to 8-bits. Format conversions in The previous discussion on YUV image NV21, YUYV and other formats processing, are 8 bit YUV format, that is, each Y, U, V component respectively occupy 8 bit (a byte). with 10 bit caps. HDR Support. Hello Is it possible to add additional Pixel Format 10-bit YUV (v210) and 10-bit RGB (r210) to ffmpeg? A problem description is below: I am trying to capture Decklink Card. More bits can do smoother gradiant to reduce banding between steps of colors. The 8-bit vs 10-bit ramp image is highly exaggerated. The AYUV format, which is a 4:4:4 format, uses 8 bits each for the Y, U, and V samples. An optimal solution on Jetson platforms is to have source in YUV422 8 bit such as YUYV or Initially it was set to 4K RGB 8 bit HDR. 2, you still cannot capture in 8-bit YUV.

The formats described in this article all use 8 bits per pixel location to encode the Y channel (also called the luma channel), and use 8 bits per sample to encode each U or V chroma sample. Or I am looking for a fastest method to convert one YUV array into RGBA array. and 10bit is enough for the quality your smartphone produces, even for your dslr (unless maybe it can produce raw and/or with separate slog data or something I recently recorded about 2 hours of footage on my a6700 in 10-bit, not knowing that I can't edit 10-bit on the free version of DaVinci Resolve, so is there some way I can convert it to 8-bit, (Lossless if possible) I don't want to record all that again. It's common for distribution, particularly because converting to YUV lets you separate luma from chroma, and then reduce YUV420 8-bit Odd Line Format Mapping DEMUX_DATA Slice YUV 420 8-Bit Data Mapping demux_data[39:30] {Y2[7:0], 2’b00} Jump to main content Up to 1-GHz Arm® Cortex®-A7, MIPI Camera, Dual Ethernet, Audio and Security . 1) I have been unable to work with files shot on a Canon C300 (10 bit MXF format, H. Well, YUV 422 (I and J versions): "has one luma plane Y and 2 chroma planes U, V. In 8-bit systems, a luma offset of +16 is added at the interface, placing black at code 16 and white at code 235. So far I've been loving Resolve, but since I downloaded the last update (16. 16 bit internal YUV conversion. Theres 3 parts to this YUV to RGB Add 10 bit YUV format(s) (fourcc unknown) Add XR30 RGB format. Example: Converting 8-bit YUV to RGB888. I had to do a little research to figure out what my "best settings" would be. But when it comes to 10 bit YUV, it plays disturbed and greenish video. 4. (YUV default), scale by bit-shifting. As far as I understand the number of colors should be higher using YUV 10/12bit limited than using RGB 8bit full. But This video he talks about the color settings, RGB 4:4:4, 4:2:2, and 4:2:0, in combination with 8, 10, or 12 bit color depth. 0: The screenshots on the HDR / 10-bit color precision KB article show the Shield being set to 10-bit and YUV 4:2:2. anyone know 10-bit raw rgb? about omnivision.

There is a lot of info: Use an AXI4-Stream Subset Converter to convert the 10-bit YUV to 8-bit YUV by modifying the tdata mapping to remove the lsbs of each component, then configure the VPSS When using ffmpeg you need to set '-pix_fmt yuv420p' if you want YUV 4:2:0 8bit output. The previous discussion on YUV image NV21, YUYV and other formats processing, are 8 bit YUV format, that is, each Y, U, V component respectively occupy 8 bit (a byte). I know the following formula can be used to convert RGB images to YUV images. YUV 420 8-bit Mode Table 6-15. Commented Jan 16, 2024 at 12:33. From the original RGB-to-YUV formulas, one can derive the following relationships for the 8-bit BT. Although it is not crucial, it’s good to know that the bit order in transmission is LSB first. 6. (If you have the vfw codec installed. Sample values are scaled 8-bit values, using a scaling factor of 2^(n-8), when n = 10 or 16. I want. [[MENTION:74962]] I’m using FCP 4. Also try ffmpeg -pix_fmts to list the available formats. Although this changes the UI display mode as expected, all videos in Plex show as YUV422 8-bit, regardless if it's HDR, SDR, 1080p, etc. We are very sensitive about lightness. Transmission order: Not sure about the sharpness difference, there might be different scaling for the unsharp filter in 8bit vs. 10bit to 8bit conversion via ffmpeg Resources. One word -- Unemployment. Yes, FFV1 is lossless The number, 256, is 2 raised to the 8th power or the 8-bit color depth. 10 bit YUV 422 lossless compressed-> 10bit YUV 422 uncompressed It would be good if FFV1 did RGB too *crossing fingers* Quote . 8-bit (luma) + 2 × 2-bit (both chroma planes) = 12-bit per pixel. I have been capturing 10 bit yuv as v410 or p210 uncompressed. I can't find AHARDWAREBUFFER_FORMAT_YCbCr_P010 defined in the latest NDK version. 7 %: Note: In the last conversion over 8 million colors turned into invalid RGB triplets, with red ranging [-179, 434], green [-135, 390] and blue [-226, 481]. 98P, bit rate of 410 mbps VBR, Cinema Gamut, Canon LOG, YUV 4:2:2 10 bit, LPCM 4ch, 48 kHz, 24 bit).

Video Bitrate calculation for uncompressed video. For example, given a YCbYCr array, which is a sequence of bytes: YCbYCr = Luma0, Cb0, Luma1, Cr0, Luma2, where 8-bit blue- and 8-bit red- difference chroma components are sampled with period 2, but 8-bit luma is sampled with period 1. poisondeathray. I'm not that familiar with 10-bit encoding; for instance, I was wondering if it is used to enhance the dynamic range (= introduce colors darker than 8-bit #000000 or brighter than #ffffff), or rather to have smoother transitions (e. g. As a consequence, there is less need to quantize to achieve a given bit-rate. However, in actual processing, we store and process data in bytes, so the final When converting to yuv 4:2:0 10-bit, should I use "limited" yuv range in the BT. HDR10 + is 10 bit but with dynamic metadata ( the tone of the HDR layer can be changed scene by scene or like the studio want Figure 42-8. The reason I specify 4:4:4 is for the following 3 applications:-multiple generations of encode/decode-extra bandwidth for titles, FX, noise correction issues etc. And I want to convert one of those images to RGB, in Linux environment. 2 lossless or V210 uncompressed that I can use in Premiere Pro or in Avisynth with FFvideosource. 10bit (e. Now in reality, according to the manual, the display supports 2160p60Hz through HDMI, with either 8-bit color depth/ chroma sampling with RGB 4:4:4. 42. Once I have a correct RGB, I'm OK. This format is supported in both linear and AFBC by Mali GPUs. Tool to generate 10-bit HDR YUV in P010 colorspace?

The resulting colours are completely washed out @wwaag's Happy Otter Scripts has a function called Import Assist that externally imports 10 bit YUV and other hostile source (GH5), and transcodes it to a number of Vegas-friendly formats -- among them Magic YUV! (A bit of circular thinking never hurt any low-budget editor in this business!) 3. 99615473 0. You can watch 10-bit HDR content on an 8 bit display just fine - I do it all the time using madVR. @mrousavy I ended up writing my own Metal shaders to accomplish this. Posts: 117; Joined: Thu Oct 04, 2012 9:23 pm; Location: Los Angeles; Re: From 8-bit YUV to 10-bit RGB. -pix_fmt is an output option for the target format. 4th Mar 2020 20:41 #29. If you have a single-channel 8-bit image to start with, you can use cvtColor(source_mat,destination_mat,CV_GRAY2RGB) to convert to 24-bit RGB. 265 to 8-bit H. By analogy, 10bit YUV means that each Y, U and V component occupies 10 bits respectively. Until now, since I have only worked on considerably shorter videos (around 3 minutes), I colored in davinci resolve and just exported either Premiere Pro XML or Final Cut XML with uncompressed 10-bit YUV 422 for the clips, thinking why not, since storage and delivery What type of the YUV pixel format are you using? The most common format is YUV4:2:0 planar 8-bit (YUV420p). ffmpeg -y -pixel_format yuv444p16le -s 4096x4096 -framerate 30 -i input. Improve this answer. There is memory copy in this case. GitHub Gist: instantly share code, notes, and snippets. 8 bit rec. 3. Fredrik Pihl Values for tv-range input video at (10, 294): - 8-bit YUV input = [235 128 128] - 8-bit RGB output = [255 255 255] (= [1. We have a 10/12 bits rendering path on macos and linux (OpenGL and basic compositor) by converting YUV 10/12 bits into RGB 8 bits directly in the compositor (through an OpenGL shader) We have no such feature in the D3D11 compositor path. Use case: override greyscale conversion to fullscale instead of bit-shifts. But for 8-bit sequences I'm getting a much higher throughput of around 450-500 fps In editing mode, it would convert from 10-bit YUV to 8-bit RGB, then on export back to 10-bit YUV, or whatever other format you export to. 1024 is not much, but OK. Then pad each component from 10 to 16 bit (there's no eays way to work with "packed" values > 8 bit in Java2D, AFAIK) . nvenc smooths out stuff, h265 keeps more detail (10 and 8 bit), x264 is behind, trying also keep details but cannot keep up like x265 does. The bottom gradient is between 4-bit and 5-bit color. SDI Color Space. There are bandwidth limits on HDMI 2. Was new to this subject - converting useless 10-bit video files to user-friendly 8-bit This topic describes the 10- and 16-bit YUV formats that are recommended for capturing, proce This topic contains the following sections: •Overview •FOURCC Codes For 10-Bit and 16-Bit YUV Multimedia Xpert knows a huge number of video formats, so it can convert virtually any format from higher than 8-bit down to 8-bit. Until recently, it was common for these values to cover the range from 0 to 255 which means they could be represented by 8 bits. I’ve had great success converting 4KHDR Blu-ray to 10 bit 4K SDR using the color space filter and BT. Stars. HDR requires 10 bit or higher for PS4 and PS5.

It is very easy to install. To avoid thess types of issues many folks cut the entire show in the DV realm and then re-render using 8 or 10-bit Does using images with 16 bits per channel result in a more accurate color conversion to YUV as opposed to images with 8 bits per channel? Does ffmpeg directly convert from 16-bit RGB to YUV or does it first convert the images to 8 I have YUV images. ) Mapping DEMUX_DATA Slice YUV 420 8-Bit (Legacy) Jump to main content Up to 1-GHz Arm® Cortex®-A7, MIPI Camera, Dual Ethernet, Audio and Security . 265 video from a 8-bit H. So you're yuv 10 bit will be more compatible and more stuff will work natively with that , other plugins or software applications would have to convert the rgb 12bit to something else to work on it. SAM9X70 SAM9X72 I can create 8bit Yuv eglImage and use it normally. Note that 10 bit formats are still padded to 16-bit,so storage size will remain the same.

I tested a bunch of games and could not tell the difference between 10 bit with chroma subsampling vs 8 bit dithered and full chroma. data is transmitted as B1 –G1– R1 –B2– G2– R2, Data in receiver’s buffer: B1 (byte 0) — G1 (byte 1) — R1 (byte 2) –B2 (byte Premiere shows no banding, but all exports do. If you like to adjust/colorgrade this and say compensate for one stop (imagine, missed the So here I am, again, to tell you that with Desktop Video 10. 5 means two 10 bit levels, and 0. Does NI Compact Vision System(CVS) support YUV 4:2:2 format(8 bit each). But i had to pack the 10 bit signal into 16 bit packets, and write the descriptors as a YUY2 media(UVC not support raw format). e. What encoder do you want to use? The libx264 (H. I used a pretty standard lossless method with quicktime ProRes uncompressed 4:2:2 10-Bit (YUV Uncompressed 10-Bit) that increased the the file size to 10 times the original file size. To check, run ffmpeg -h encoder=xxx where xxx is the codec name and look for a line starting with Supported pixel formats:. This could just be coincidence, but has me curious: Can anybody confirm (or disprove) that we are indeed getting the stream encoded with 4:2:2 color subsampling when using the 10-bit option? If so, that would a welcome step forward We will clamp 10-bit DPX file to 8-bits, apply the blur to get an 8-bit frame, apply the color corrector to the 8-bit frame to get another 8-bit frame, then write 10-bit DPX from 8-bit data. View Profile View Forum Posts Private Message Member Join Date Sep 2007 Location Canada. Product Pages. Is it possible to render to an 8-bit texture framebuffer on OpenGL ES 2. RGB888. ” OpenCV provides a lot of color conversions, but I didn’t see any reference to 10 bit formats in the list. Reply reply Best way to convert YUV 422 Video to RGB(A) upvote ffmpeg.

The top red gradient is really 8-bit color. I can confirm that, for 10-bit video range YCbCr formats, the Y channel goes from 64 to 940 and the Cb/Cr channels goes from 64 to 960. Win10/11 can actually use HDR in 8bit RGB mode, which looks identical to 10bit RGB on my TV (8bit + FRC). 3 CSI-2 YUV420 8-bit (Legacy) Odd Line Format (1, 3, 5, etc. The ISP takes 12-bit Bayer pattern as input and generates 8-bit YUV as output. I can view 8 bit - 10 bit difference on my If you would like to use gstreamer, have to capture YUV420 8 bit data. mov. If you are starting from a 3-channel 24-bit YUV image with two channels full of zeros, you can use the split() function to get the Y channel out of it, then convert that as described above. 5 YUV 422 10-bit Mode Jump to main content I'm encoding some 4K 10-bit YUV test sequences using NVENC HEVC encoder. Color space: YUV Chroma subsampling: 4:2:0 Bit depth: 10 bits Bits/(Pixel*Frame): 0. the 10 bit frame to a format that can be assigned to an OpenCV Mat without loosing information by converting from 10 bit to 8 bit? I would really like to have the extra precision of the 10 bit signal compared with the 8 bit signal. I use that recommended setting with auto color space switching ON. Topik ini menjelaskan format YUV 10 dan 16-bit yang direkomendasikan untuk menangkap, memproses, dan menampilkan video dalam sistem operasi Microsoft Windows. For an example sequence and configuration, I use the following command. 4 or 4. But the NDK doesn't seem to support the 10bit P010. . Real world SDR YUV material (movies) contain such "out of range" values that possibly would be better displayed as The bit depth of YUV video is usually indicated in bits per channel because of chroma subsampling. 709 define full black as Y=16 and full white as Y=235. 9961547] Values for pc-range input video at (10, 319): - 8-bit YUV input = [255 128 128 422 10/12bit over hdmi 2. 8, 10, 12-bit RGB 4:4:4 in 2D modes up to 4Kp30 DCI and 8, 10-bit YUV 4:2:2 in all 2D modes. 97 The algorithm is divided into two main functions iCAM_Encode (the pre-processing part) which converts the HDR frames into 10-bit codec suitable YUV files and iCAM_Decode to convert decoded YUV files to output EXR frames. Forks. Note: which YUV formats are actually supported and how to allocate them is OS and platform dependent; even though the GPU supports it doesn't necessarily mean that the host platform does (e. In 10 bits I am able to draw a black-and-white image but am having trouble addressing the U and V samples. The dynamic range compression of a HDR Bayer pattern from sensor (12-bit PWL compressed from 16-bit linear in your case) to a 12-bit Will just answer my own question after reading more on this and some actual testing. Table 43-16. 0 is the only way to display hdr at 60hz. My capture card is able to deliver in several YUV 444 8 bit formats namely V308, IYU2, V408 and I have been trying without success to capture directly to magicyuv 444 8 bit lossless with virtualdub. mp4 If I use ffprobe on the output. Have a look at vooya which can play most of the available YCbCr formats out there. Considering a simpler, but fully AVX2/NEON implementation When encoding with the 10-bit tool, the compression process is performed with at least 10-bit accuracy compared to only 8-bit otherwise. ) Mapping DEMUX_DATA Slice YUV 420 8-Bit (Legacy) Jump to main content Arm® Arm926EJ-S™ Processor-Based MPU, 800 MHz, MIPI DSI or CSI-2, LVDS, RGB, 2D Graphics, Gigabit Ethernet with TSN, CAN-FD, Octal/Quad SPI, Crypto, PUF . Search. Colour sampling is a YCbCr thing and the concept is not applicable to RGB - there is only YCbCr 4:4:4. transform YUV420 10bits sequence to 8bits. So there is less truncation errors, especially in the motion compensation stage, increasing the efficiency of compression tools.

Normally I 'd use the Video Processor MFT to convert to RGB but , as of now, the MFT doesn't convert other than 8 bit samples. A DPX file with a blur and a color corrector exported to DPX with the max bit depth flag. You could convert at 10-bit and truncate to 8-bit after, but that will likely use more resources in the VPSS. Is there a way to conver these to RGB? Hello Is it possible to add additional Pixel Format 10-bit YUV (v210) and 10-bit RGB (r210) to ffmpeg? A problem description is below: I am trying to capture Decklink Card. ; Make sure your codec supports it. 6. Some people have taken to encoding 10-bit 4K material in 10-bit 2K, so in that case, yes, by all means set non-4K to 4:4:4 10-bit. However, in I422, chroma planes (blue and red projections) are sub-sampled only in the horizontal dimension, still by a factor of 2. 4 bytes for luma and one byte for each color plane. There is no 4:4:4 in RGB - it’s just RGB at 8-bit or 10-bit. 24th Aug 2023 02:51 #2. 5 Good evening! I hope your day is going great. Readme Activity. tiff with 8-bit 444 and 10-bit 422 (tif supports yuv). 0 so if vegas cant do that ill just have to keep hunting for a more capable software Don't think I understand what you are asking. Romeo Ninov Romeo Ninov. Conversion from and to float is always full-scale. 2 to 4. PC to TV Levels -- A Comedy of Errors. Follow edited Jan 15, 2013 at 14:46. Then do . 078 Not sure what the correct range values are for 10-bit YUV – mrousavy. HDR static metadata packing, HLG and PQ transfer characteristics. As far as file size, John, was your Sony YUV codec 8- or 10-bit? If Magic 444 is truly 4x smaller than Sony 422, this may be "case closed" on size, quality, and speed. Hardware HEVC encoder uses pixel formats p010le and p016le for 10-bit output where first one produces yuv 4:2:0 and the second one yuv 4:4:4. View Profile View Forum Posts Private Message Member “It is a 10 bit per component, YCrCb 4:2:2 format in which samples for 5 pixels are packed into 4 4-byte little endian words. (Decoding and looking at the raw pixel data, I can confirm that the precision has decreased from 16 bits to 10 bits). YUV 4:2:2 stores the luma plane at full resolution and both chroma planes at half resolution (only one pair of chroma sample for each 2×1 block of luma samples) so at 8-bit per component that works out to: 8-bit (luma) + 2 Activity › Forums › Apple Final Cut Pro Legacy › Transcode YUV 4:2:2 to uncompressed 10 bit .

REC 601, REC 709 and REC 2020. Since the tiff is lossless (usually), banding should not occur during rgb->yuv conversions. I want to do some measurements on a video signal having 10 Bit YUV format. Format 4:2:0; Format 4:2:2; Format 4:4:4; I'm trying to import 10/16 bit YUV HDR video files in my video sequencer and I got , with media foundation, a MFVideoFormat_P010, which is, according to the docs, a 4:2:0 10-bit sample. Does XnView support these converts? Please give me any advice Thank you very much, Josef Zitko. License. I think I can do conversion using imagemagick. But consumer tape formats have very little chroma bandwidth. In the following formula, R, G, B, Y, U, V are all 8-bit unsigned integers, and intermediate values are 16-bit unsigned integers. So the valid range of Y is 235 - 16 = 219. In the 8 encapsulation of 8-bit/component and 10-bit/component uncompressed YUV data into AVI or MOV files; YUV Convert is a software product for Windows. This repo also provide PSNR calculation for 8-bit image. For 1920x1080 10-bit sequences, I get around 50-60 fps with HEVC encoder. For example to play the 10bpp sequences provided by the HEVC standardization which are in 4:2:0 10bpp, you can use the following ffmpeg command: The recommended YUV formats are described in detail in the topic Recommended 8-Bit YUV Formats for Video Rendering. I want to swap the U and V bit in YUV format, from NV12 YYYYYYYY UVUV // each letter presents a bit to NV21 YYYYYYYY VUVU I leave the Y planar alone, and handle the U and V planar by the function Contribute to kornelski/yuv development by creating an account on GitHub. If I disable the fallback to p010le, the output would be Bit depth : 8 bits but What is the most accurate way to convert 10-bit full-range YUV to RGB per BT. I have cheated by multiplying the 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进行处理，记录一下方法。 You only need one VPSS if you use the subset converter to convert your 10-bit 4:2:2 YUV to 8-bit 4:2:2 YUV before the VPSS colorspace converter and set the VPSS for 8-bit. input wire yuv_hs , input wire yuv_vs , input wire yuv_de , input wire [9 :0] yuv_y , input wire [9 :0] yuv_c , wire signed[9:0]rgb_g_cut=rgb_g>>10; wire signed[9:0]rgb_r_cut=rgb_r>>10; reg signed [7 :0]rgb_8b_b=0; reg signed [7 :0]rgb_8b_g=0; reg signed [7 :0]rgb_8b_r=0; reg [3:0]sft_yuv444_hs = 'd0; Luma is on one 8/10/12 bit channel while Chroma is interleaved on the other 8/10/12 bit channel. You can also do 4K60 YCbCr422 10-bit over HDMI 2. Only the source content needs to be 10-bit or 12-bit as it's decoupled from the display RGB / YUV Intermediate Codec Shootout - 2018. This is a PSNR calculation for 10-bit YUV of "Low-Complexity Intra Coding in Versatile Video Coding", a deep learning based 10-bit image Super-Resolution model. It’s possible you will have to write a conversion function yourself. To not include an original is kind of faux-pas though. It's the conversion from the libyuv's 10-bit RGB that I take the 10-bit number and divide it by a 2048 to scale it into a range of [0. For using jetson_multimedia_api, a possible solution is to capture data in YUV422 10 bit into CPU buffer, and convert/copy to YUV420 10 bit NvBuffer. its 422 because it halves the colour signal and overall has 33% less data so you can run at 60hz but the human eye doesn't care about color nearly as much as lumination (the 4 in 422) and so the difference between hdr 422 vs full colour rgb is mostly negligible, especially for movies its not noticeable at all. Thank you, The number, 256, is 2 raised to the 8th power or the 8-bit color depth. exe -s:v 1920x1080 -r 30 -pix_fmt yuv420p16le -i depth_yuv420p16le. Its great, but he mainly talks about hdmi 2. Can quicktime not display 10-bit video? (I'm working on a 10-bit display) Data type is set to 0x19 or 0x1D. 2020. This means that each of the RGB channels has 256 shades so there are 256x256x256 or 16,777,216 colors in total in this 8-bit RGB system.
