magicyuv enc: width and/or height must be multiple of 2 for yuv420p/yuv422p pix_fmts

[ami_stuff]

for -pixfmt yuv420p - width and height must be multiple of 2

for -pixfmt yuv422p - width must be multiple of 2

otherwise the original codec (MagicYUV v1.2rev2) will reject/won't decode files created by ffmpeg

Could you at least explain why you won't fix certain issue? You are acting very rude.

[Elon Musk]

Because if it was not obvious by now, its not ffmpeg limitation but "other" one.

[ami_stuff]

Limition of "other" one? You mean reference decoder? The ability to create incompatible files with reference decoder will just introduce only problems for the users, as long as you call your encoder "magicyuv".
