[MPlayer-users] Need help with deblocking (-vf pp)

[John Brown]

-vf pp=de/-al works well in MPlayer, but seems to have no
effect in MEncoder. The resulting mpeg looks just as blocky with or without 
pp.
See command line below, from a Windows batch file:

.
mencoder.exe %1 -ss 58 -endpos 15 -quiet -priority belownormal -of mpeg
   -mpegopts format=dvd -vf scale=704:480,pp=de/-al,harddup -oac lavc
   -ovc lavc -lavcopts
   vcodec=mpeg2video:vbitrate=1645:aspect=4/3:acodec=ac3:abitrate=96
   :vrc_buf_size=1835:keyint=12:trell:mv0:mbd=2:dia=-10:predia=-10:cmp=2
   :precmp=2:subcmp=2:cbp:vqmin=1:lmin=1:dc=10:vpass=1:turbo
   -ofps 30000/1001 -srate 48000 -af lavcresample=48000 -o %2
   -passlogfile stats.log -quiet >> log.txt 2>>&1

Pass 2 is identical except, of course, that vpass=2 and there is no
turbo.

I would like to remove the blocks without using a higher bitrate. When I
encode at 352x240 with otherwise identical parameters at 1645 Kbps, then
play the result at twice the size, I don't get the blocking, even
without -vf pp, so I am assuming that I don't need more bits. Is that a
valid assumption?

My source is a 230 MB .ogm: 24 min, 23.976 fps,640x480 DX50, Ogg/Vorbis 96 
kbps. I want my DVD-compliant mpeg to be 299 MB.
