Nowadays, we live in a KDE4 world for real, so it’s time to update my “dump audio from video file” service menu 😉 It should work both in Konqueror and Dolphin.
Create a file with the following contents and put it in one of your service directories (which you can find out by running “kde4-config –path services” , typically you will have something like $HOME/.kde4/share/kde4/services )
[Desktop Entry]
Type=Service
Encoding=UTF-8
ServiceTypes=KonqPopupMenu/Plugin,video/*
Actions=extractaudio
[Desktop Action extractaudio]
Name=Extract audio
Name[en-GB]=Extract audio
Exec=mplayer -dumpaudio %u -dumpfile %u.dump
Icon=speaker
