Looks like a XY problem. > We propose a new raw image/video format, R4M, that extends Y4M to support: Please explain why you think storing raw video or any other lossless codec into a standard container format like Matroska or Nut does not satisfy your needs. > * (a) every `pix_fmt` that ffmpeg supports. The implementation would > support generic AVPixFmtDescriptor's, so any new pixel format based on > it will be automatically supported. This includes > planar/packed/semiplanar, yuv/rgb/bayer, and others. This does not make any sense. Please mediate on the fundamental difference between in-memory representations and permanent storage representations. PS: do not Cc me. Regards, -- Nicolas George
