This is, I believe, the first time I've posted to this group. I have
a .ogm file which through a script I found at the transcode website,
I've been able to convert it to an .avi. The problem is there is no
sound. tcprobe -i confirms this. This is the script:
#!/bin/sh
#
# This script converts dual audio soft-subbed .ogm files
# to hard-subbed .avi files using the second audio track
# and the first subtitle track.
# I recommend using a 24 pixel subtitle font, anything
# less and folks *will* complain.
#
# Note that the bitrate of 3000 is HUGE. I do this
# because the .avi I create here is just an intermediate
# product. If you are only after a .avi, you should be
# using a bitrate of <= 1800 and a two-pass encode!
#
# 2-pass encoding is done by adding a vpass=1 option
# to lavcopts and just copying the audio on the first
# pass and setting -o /dev/null. Then use the vpass=2
# option on the command shown here and the dynamic
# analysis data from pass 1 will be used for the encode.
# Play with different vbitrate settings to see what the
# real optimal size/quality point is.
#
# Note that changing .ogm to .mkv in this script will
# make it work on .mkv files. Slight mods will allow
# it to be used on dvd's.
#
files="$@";
for arg in $files ;
do
file=`echo $arg | sed -e 's/\.ogm$//'`
mencoder -oac mp3lame \
-ovc lavc \
-lavcopts vcodec=mpeg4:vqscale=2:vhq:v4mv:trell:vbitrate=3000
\
-aid 1 \
-sid 0 \
-o $file.avi $file.ogm >& /dev/null
done
# end of script
Any thoughts? Is there a problem with the script? THanks.
