Question batch file to convert every file in a directory with mencoder.


I am trying to build a perl or shell script that does the following.
After I manually ftp a file to /home/incoming the script runs to see:

If new files have been completly uploaded copy files to /home/needencoding

encode all new files with:
mencoder filename.dv -o newfilename.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=800:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -vf scale=450:400 -srate 22050

copy files to /home/outgoing

The goal is to have a directory on my server that files get ftp'd to.
The server automatically moves the files to the right directory, encodes them, then puts them in another directory they can be copied from.

I already have mencoder command working, I just need a way to batch all the encoding whenever files get uploaded.

How do I tell if a file in a directory has been completely uploaded via ftp or if it is still being uploaded? The file appears before it is completed.

I will then tell the server to run the script every 5 minutes so whenever a file gets uploaded it gets copied over.

Thanks in advance for your help.

You could put the following in a script and run it out of cron. It would need commands added to move the files once they're processed. I've just copy/pasted from a script of mine, so you'll also need to modify the mencoder options:
Code:
for i in *flv;
do
  ORIGINAL=`basename $i .flv`
  NEWNAME=${ORIGINAL}.mpg
  /usr/bin/mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf \
  -vf scale=720:576,harddup -srate 48000 -af lavcresample=48000 \
  -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=15:trell:mbd=2:precmp=2:
subcmp=2:cmp=2:dia=-10:predia=-10:cbp:mv0:dc=10:vstrict=0:acodec=ac3:abitrate=192:aspect=4/3 \
  -ofps 25 -o $NEWNAME $i
done
