The NV12 image format is commonly found as the native format from various machine vision, and other, video cameras. Description. Since ffmpeg encodes in “yuv420p” when “yuv420p” or “nv12” or “nv21” is chosen, why let the possibility to encode in “nv12” or “nv21”? abgr: abgr. Here’s what you are doing –. It is yet another variant where colour information is stored at a lower resolution than the intensity data. For example to read a rawvideo file input.raw with ffplay, assuming a pixel format of rgb24, a video size of 320x240, and a frame rate of 10 images per second, use the command: The crucial part of this workaround seems to be the ability to force a particular pixel format, which is not an option available in the videoconferencing applications I'm trying to use. FFmpeg Pixel format一覧. The palette is transported in * AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is * also endian-specific). The same as NV12 except the interleave order of U and V is reversed. ffmpeg is slow doing the BGR0 -> nv12 conversion, and by default it will be 601 rather than 709. But when I run this command: ffmpeg -i input.mp4 -vcodec h264_nvenc -pixel_format rgb0 output.mp4. 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). I download a video from youtube with youtube-dl tool. [FFmpeg-devel] [PATCH 1/2] avutil: add P010 pixel format Hendrik Leppkes Thu, 07 Jan 2016 03:12:08 -0800 P010 is the 10-bit variant of NV12 (planar luma, packed chroma), using two bytes per component to store 10-bit data plus 6-bit zeroes in the LSBs. ffmpeg -h encoder=h264_nvenc. Then look at the pixel format of the retrieved frame, it is usually NV12 format when using nVidia decoding. 3, To Convert a 720x480 nv12 (yuv 420 semi-planar) image to png ffmpeg -s 176X144 -pix_fmt nv12 -i ABC.yuv -f image2 -pix_fmt rgb24 ABC.png 4, To cut the clip for certain duration[HH:MM:SS.xxx] ffmpeg -i myInputFile.avi -pix_fmt nv12 -f avi -vcodec rawvideo convertedFile.avi This converts it to NV12. Its practically just NV12 bumped to 16-bit storage and 10-bit data in the MSBs (6 zeros in the LSBs). I don't know its output because the ffmpeg support for this board is not ready yet but I guess it's NV12 (the color format for CUDA). Added option, default video decoding format for unusual formats (There are many formats that virtualdub doesn't handle, now you can choose how they are decoded) Updated ffdlls to 2.1.3 0.8.0.6 Fixed crash from FFDshow dlls logging Added more native virtualdub video formats, so less are converted to rgb-> yuv 410p, 422p, 444p, nv12, nv21 Long story short after realizing OBS wasn't going to work no matter what I tried I moved on to FFmpeg, and after pulling my hair out for months at a time I was able to capture my main display flawlessly using FFmpeg.
