in cacko, I've managed to get 15fps smoothly with 640x480 (widescreen video), with 128mbps mp3, playing back on mplayer.

here's a script I was using to try it out; as I tried out new things I copied the command to keep the old one on hand.

#!/bin/bash

INFILE="$1"
OUTFILE="$2"
echo "encoding $1 outputting to $2"
set -x

#mencoder -ofps 8 "$1" -o "$2" "${@:3}" -lavcopts
#vhq:vcodec=mpeg4:vbitrate=40:vrc_maxrate=70 -ovc lavc -lavcopts
#vbitrate=150 -oac mp3lame -lameopts abr:br=32 -zoom -vf #scale=320:-3,expand=-1:-1:-1:-1:1,rotate=1 -sws 9 -af resa
#mple=22050 -srate 22050

#mencoder "$INFILE" -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=150:vpass=2 -lameopts abr:br=64:mode=3 -vop scale=64
0:480 -oac mp3lame -ofps 15 -o "$OUTFILE"

# works but no sound on x86 playback nor zaurus
#ffmpeg -i $INFILE -v 0 \
# -deinterlace -vcodec mpeg4 -4mv -b 224 -r 15 -aspect 16:9 -s 640x400 -hq \
# -acodec vorbis -ab 64 -ac 1 $OUTFILE

# works but blocky
#ffmpeg -i $INFILE -v 0 \
# -deinterlace -vcodec mpeg4 -4mv -b 224 -r 15 -aspect 16:9 -s 640x400 -hq \
# -acodec mp3 -ab 64 -ac 1 $OUTFILE

# not too bad
#ffmpeg -i $INFILE -v 0 \
# -deinterlace -vcodec mpeg4 -4mv -b 256 -r 15 -aspect 16:9 -s 640x360 -hq \
# -acodec mp3 -ab 64 -ac 1 $OUTFILE

AV=384
AB=64
# 50% horiz scaling, 16:9, top quality?
ffmpeg -i $INFILE -v 0 \
-deinterlace -vcodec mpeg4 -4mv -b $AV -r 15 -aspect 16:9 -s 640x360 -hq \
-acodec mp3 -ab $AB -ac 1 $OUTFILE_mp4-$AV_mp3-$AB.avi
