batch convert wmv

[easoukenka]

I am looking to convert tons of wmv files to a divx compatible avi file. I have been reading about mencoder and ffmpeg and they seem to both do what I want however I would have to do one at a time which is to time consuming for all the files I have. I basically want to ready my 200gb of wmv to work on my dvd player.

Oh what kind of quality loss will I face when I convert?

Re: batch convert wmv

the new preview version of avidemux can open/decode wmv to any other format and i think it has a batch mode/feature, but i'm not sure...

Re: batch convert wmv

This seems to work:

Make text file (convert.sh) and put there:

#!/bin/bash

FLIST=`ls -1 $1 | grep wmv`
for F in $FLIST
do
  mencoder $F -ovc xvid -xvidencopts pass=1 -oac copy -o /dev/null
  mencoder $F -ovc xvid -xvidencopts pass=2:bitrate=1000 -fps 23 -oac mp3lame -lameopts cbr:br=96:mode=0 -o $F.avi
done

Put it at the same folder as the wmv's are. In the konsole:

sh convert.sh

This script will do two pass conversion from wmv to avi (xvid, mp3).

Tried this with four wmv clips (15 sec, 640x480, 1,8 M) VLC told:
Sound codec wma2
Bitrate 96 kbps
Windows Media Audio 9
Video codec WMV 3
Windows Media Video 9
Frame rate 23fps

After conversio i have four avi (xvid, 2,0 M)
Audio codec MP3
Bitrate 96 kbps
Video codec XVID
Frame rate 23 fps

Note
This doesn't remove original wmv's.
New avi's are named as: interesting.wmv -> interesting.wmv.avi.

Re: batch convert wmv

Is it just me, or did you write a Bash script and execute it with sh?

Do you mean something like this ?

It annoys the hell outta me when people write bash scripts with #!/bin/sh! sh is not bash! Many systems (mine included) have /bin/sh as sh and not bash, so when bash scripts call /bin/sh and start using bash only features, it doesn't work. Took me a little while to figure out why some init scripts I got weren't working, until I realized that.

So, if you are writing a bash script, use #!/bin/bash please. Assuming everyone has /bin/sh linked to bash is wrong. If you're writing a sh script, please test it with sh and not bash.

Note
In Dapper /bin/sh is symlink pointing to bash
In Feisty /bin/sh is symlink pointing to dash

In Dapper:

~$ whatis sh
sh (1) - GNU Bourne-Again SHell
:~$ whatis bash
bash (1) - GNU Bourne-Again SHell
:~$ whatis dash
dash (1) - command interpreter (shell)

And in Feisty:

:~$ whatis sh
sh (1) - command interpreter (shell)
:~$ whatis bash
bash (1) - GNU Bourne-Again SHell
:~$ whatis dash
dash (1) - command interpreter (shell)

So In the konsole:

bash convert.sh

Or convert.sh starts

#!/bin/sh
...

and in the konsole:

sh convert.sh
