Remarks Multi-plane Android YUV 420 format This format is a generic YCbCr format, capable of describing any 4:2:0 chroma-subsampled planar or semiplanar buffer (but not fully interleaved), with 8 bits per color sample. 2. For V4L2_PIX_FMT_YVU420, the Cr plane immediately follows the Y plane in memory. This format can be used for processing the input frames before saving to disk or some other action. Jun 25, 2025 · The AYUV format, which is a 4:4:4 format, uses 8 bits each for the Y, U, and V samples. I420 is YUV 4:2:0 format with fully planar ordered format. Example: ffmpeg -i input. Full marks to Intel for registering the same format twice and full marks to Microsoft for not picking up on this and rejecting the second registration. YUV can also be defined using more than 8 bits per sample for some applications. org/yuv. Image.
