Converting Files with Linux September 21st, 2011 No Comments
The following tipps work under a linux terminal:
Inhaltsverzeichnis
Image Files
If you want to change image files via terminal, ImageMagick is a good choice.
Resize Images to a maximum resolution
convert "YourOldPicture.jpg" -resize 1600x1600 "YourNewPicture.jpg"
Create a Black-and-white picture and compress it
djpeg "YourOldPicture.jpg" | ppmtopgm | cjpeg -qual 70 >"YourNewPicture.jpg"
Rename Pictures
rename -n ’s/\.jpg$/\.JPG/’ *.jpg
Audio Files
Normalize Audio
Give all mp3 songs the same sound level (it’s called Audio normalization)
mp3gain -a *.mp3
Merge mp3 audio files to one
mp3wrap merged.mp3 one.mp3 two.mp3
wav2mp3
Convert all *.wav-files in one folder two *.mp3-files and remove the *.wav-files
for i in *.wav;do lame "$i" "${i%wav}mp3"; rm "$i"; done
Video Files
For quite a lot purposes is the command line tool FFmpeg with its lots of options a good choice. For others might MEncoder be better. You might also want to install some codecs first:
sudo apt-get install libavcodec-extra-52 libavdevice-extra-52 libavformat-extra-52 libavutil-extra-50 \
libpostproc-extra-51 libswscale-extra-0 libavcodec-unstripped-52 ubuntu-restricted-extras
Merge many video files to one
cat One.mpg Two.mpg Three.mpg | ffmpeg -f mpeg -i - -vcodec copy -acodec copy "Merged.mpg"
avi2mpg
ffmpeg -i "Original.avi" "New.mpg"
mp42mpg
ffmpeg -i "Original.mp4" -target ntsc-vcd "New.mpg"
mod2avi
?
vcd2avi
mencoder vcd://2 -o "New.avi" -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2000
ogv2avi
mencoder "Original.ogv" -ovc xvid -oac mp3lame -xvidencopts pass=1 -o "New.avi"
wmv2mpg
aspect=16/9 should eventually be changed to 4/3 or other aspects
mencoder -of avi -ofps 25 \ -oac mp3lame -lameopts cbr:br=112:aq=3:mode=0:vol=0 \ -vf hqdn3d,softskip,harddup \ -ovc xvid \ -xvidencopts bitrate=501:max_key_interval=37:aspect=16/9:turbo:nochroma_me:notrellis:max_bframes=0:vhq=0 \ Original.wmv \ -o New.avi
mkv2avi
mencoder "Original.mkv" -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=6000 -oac mp3lame -lameopts vbr=3 -o "New.avi"
