Mencoder Video Converter Info - Page 3

transcoding from one lossy codec to another results automatically in a loss of quality. Also you have to be more precise what you understand of "bad sound".

hello.
I'm french and have difficulties to translate and describe exactly what the sound is,so...
-no music, no conversation can be heard
-only constant and insufferable noise.
thanks

I've written a bash script to automate the conversion progress.

You can use it for just converting movies to a compatible format, ore use it for autocropping 16:9 movies to the m6 display format 4:3.

It also automatically detects those black bars at the top and the bottom of some movies faking a 4:3 resolution and crops to *real* 16:9

Code:

#!/bin/bash
#
# bash script for converting videos to a meizu-m6 compatible format
# autodetecting and -removing those black fagbars faking a 4:3 resolution
# autocropping 16:9 to 4:3 
# 
# (c) 2008 by antisystem@jabber.org

echo
echo "Do you want to crop the video to 4:3?  [y/n]"
echo "Standard is No"
echo
read crop


if [ "$crop" = "y" ]; then
	mplayer "$1" -vf cropdetect -frames 5 -ss 600 -vo null -ao null >/home/$USER/.meizucrop
	cropres=`cat /home/$USER/.meizucrop | grep crop | tail -n 1 | cut -d "(" -f 2 | cut -d ")" -f 1`
#	mplayer "$1" $cropres,scale=-2:240,crop=320:240 
	mencoder "$1" -idx -noodml -ofps 20 $cropres,scale=-2:240,expand=320::::1,crop=320:240,rotate=1 -ovc lavc -ffourcc XVID -lavcopts vcodec=mpeg4:vbitrate=384:vmax_b_frames=0:vhq -sws 9 -srate 44100 -oac mp3lame -lameopts cbr:br=128:mode=0 -o "$2"
else
#	mplayer "$1" -vf scale=320:-2,expand=:240:::1,crop=320:240
	mencoder "$1" -idx -noodml -ofps 20 -vf scale=320:-2,expand=:240:::1,crop=320:240,rotate=1 -ovc lavc -ffourcc XVID -lavcopts vcodec=mpeg4:vbitrate=384:vmax_b_frames=0:vhq -sws 9 -srate 44100 -oac mp3lame -lameopts cbr:br=128:mode=0 -o "$2"
fi

exit 0

working fine for me - if you have problems or questions, feel free to send me a mail.

I wonder why u linux guys invent the wheel each day again ? There are a couple of linux scripts now in this forum, but you don't want to work together and use the synergy.
