vd staggered into the Black Sun and said:
I am thinking of installing MythTV on Ubuntu.
I want to rip about 100 DVDs and compress as much as possible, but
preserve music tracks for Karaoke. What tool, compression format
would be able to do this? Is this built into MythTV?
Ripping DVDs: dvd::rip or potentially other things. MythTV is supposed
to be a PVR more than a DVD ripper/encoder, but browsing the features
page shows it might work. If you need to remove vocals from audio CDs,
I don't know what you'd do.
I want to be able to play back these ripped streams in a very user
- Use a remote to select a song
- Use a remote to fast forward, backward
- Ability to search for a song (by going with alphabetical letters
or something like that)
Many remote controls don't have alphabetic chars on them. I think
searching will be semi-difficult to implement.
What kind of TV card would have a remote for this?
Remote controls are totally orthogonal to TV cards. I have an ATI
Remote Wonder II, a USB device supported by the ati_remote2 kernel
module. All keys and the mouselike thing are recognized. (These used
to be supported via LIRC, but now they generate keycodes.) Many things
like xine and mplayer can be configured to look for those keycodes and
do various things (FF, REW, pause, volume up, etcetera.)
a list of compatible TV cards from MythTV wiki, but
These are TV-in cards, things that convert cable or over-air TV to
(usually) MPEG-2 streams. Are you sure you're not looking for a TV-out
I want to connect the video-[out] to the TV, and the sound to the
normal speakers (by normal, I mean non-PC speakers).
Set up xorg.conf such that the TV is a Monitor. The specifics vary
depending on your video card. There are several very useful and lucid
appendices about this topic in the README for the evil binary-only
nVidia modules. It's a little less easy if you're using fglrx (big
surprise.) Since audio-out plugs are pretty standardized, you
should have no trouble plugging "normal" speakers into your sound card.
You might need an adapter ($5 or so).
How do I set it up to just turn on, and go right into the MythTV?
Fiddle with /etc/inittab, have the default runlevel run a script that
su's to the normal user, then does a startx. Have that user's .xinitrc
execute the commands needed to start MythTV (or whatever you need).
however, I want it to feel like a computer (in a non admin mode),
startup very very fast, and to users, only the remote is available,
x86 machines take a while to boot. You're not going to be running many
services, so that'll help. You may want to consider doing
suspend-to-RAM instead of shutting down, if your machine allows
resume-from-S2RAM by pushing the power button once.
and also shut down using the remote.
Have the .xinitrc start xbindkeys, use xbindkeys to bind the "power"
button on the remote to "sudo shutdown -h now" or whatever. I think
doing this will be more work than you anticipate. I never checked
freshmeat.net for keyword "karaoke", so I don't know whether anyone's
written a frontend that would be usable by drunken businessmen. But
it's all certainly possible. HTH,
Stupidity got us into this mess--why can't it get us out?
