The image height must be aligned to a multiple of 128. The layouts of the luma and chroma planes are identical. V4L2_PIX_FMT_NV12_8L128 is similar to V4L2_PIX_FMT_NV12M_8L128 but stores two planes in one memory." ----- Original Message ----- From: "Kieran Kunhya" To: "FFmpeg development discussions and patches" Sent: Monday, February 6, 2023 7:15:22 PM Subject: Re: [FFmpeg-devel] Request for assistance with adding new pixel format (NV12_8L128) in FFmpeg On Mon, 6 Feb 2023 at 15:43, Le Bao Tin Ha wrote: > I hope this email finds you well.
