[MPlayer-users] feature request/question on experimental code

[Sycotic Smith]

Hi,

I was playing around with the experimental -of mpeg and noticed something peculiar.  If the dimensions of the input file are larger than the standard mpeg dimensions, the output file gives errors when playing with mplayer, AND is unplayable with any M$crap player.  Error follows below.  I can upload a few MB of both files if needed.  This is NOT a bugreport, just merely a user asking maybe a dumb question.  I know how to make it the proper size, but should it maybe instead just give ONE warning at runtime instead of every few frames?  Or, should it automagically 'scale' to fit the standard when encoding?
