[MPlayer-users] oo many frames removed with softskip

[Darwin O'Connor]

The source material is a Hollywood movie, it the source should be 24fps.
Also, if I use -mc 0 the result is smooth.

For example the file http://doconnor.homeip.net/ToyStory.mp4 is smooth. It
was generated with this command

mencoder ~mythtv/3048_20130316180000.mpg -o ToyStory.mp4 -ovc xvid
-xvidencopts fixed_quant=9 -ss 58 -endpos 10 -oac lavc -lavcopts
acodec=libvo_aacenc:abitrate=128 -vf
filmdint=io=30:24/fast=0/sad_thres=2048,scale=320:180 -mc 0 -fps 60000/1001
-ofps 24000/1001 -demuxer lavf

The file http://doconnor.homeip.net/ToyStory_softskip.mp4 is jerky. It was
generated with this command:

mencoder ~mythtv/3048_20130316180000.mpg -o ToyStory_softskip.mp4 -ovc xvid
-xvidencopts fixed_quant=9 -ss 58 -endpos 10 -oac lavc -lavcopts
acodec=libvo_aacenc:abitrate=128 -vf
filmdint=io=30:24/fast=0/sad_thres=2048,softskip,scale=320:180 -fps
60000/1001 -ofps 24000/1001 -demuxer lavf

I scaled both down to reduce file size, but the effect can still be seen.

I'm using Gentoo mplayer 1.1-r1
