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.
