I have recently been trying to capture audio from some video clips that I have, and just didn't know how to do it. I thus stumbled upon an awesome way using Ubuntu Studio's default movie player, Totem Movie Player.
It is very simple, let me explain...
- Open JACK and start it.
- Open your video of choice using Totem.
- Go to Totem's Edit menu and select Preferences.
- Select the Audio tab in preferences.
- Use the scroll down menu to change the Audio Output Type to AC3 Passthrough
- Your movie audio is now passed through JACK and can be recorded with any recording package which uses JACK i.e. Ardour.
- The Totem audio outputs can be viewed from JACK's Connect menu.
