Fine, but it's inevitable that the encoder supports the J formats still
for a while.

Why are you all dismissive about this?

Because we have an established way to remove things like this, and
that doesn't happen over night.
Its not ok for stuff to stop working without a replacement in place
for a sufficient time before that, so people can migrate.

First, implement replacement and add visible deprecation messages -
and then wait the established deprecation period before actually
removing it.

Bullshit, J formats are deprecated for ages.

ffmpeg -i input.avi -f avi -codec:v mjpeg -pix_fmt yuvj420p -y output.avi

Prints warning "deprecated pixel format".

ffmpeg -i input.avi -f avi -codec:v mjpeg -pix_fmt yuv420p -color_range jpeg -y output.avi

Prints warning "incompatible pixel format" plus "deprecated pixel format".

Guess which command-line is currently implemented in my (and I assume most other) scripts. I very much welcome your work on cleaning up this mess, but please allow for some migration period.
