Medion X10 remote and Linux

I've recently bought a remote for my PC. I thought it would be quite convenient to have one especially that it could be quite handy during watching DVDs.

I picked an inexpensive, radio operated, USB Medion X10 - around $10.

After plugging the USB dongle it turned out that the remote becomes a HID - dobling the keyboard. It was nice but not exactly what I needed. I want to have a remote control for my multimedia pplications - not to control the computer.

So here comes the magic word LIRC: Linux InfraRed Control.  It's a little bit misleading since the remote has nothing to do with InfraRed, but LIRC is actually an infrastructure which allows to control applications with remote controls. So I installed lirc:
apt-get install lirc
Upon configuration I selected ATI/NVidia/X10 RF Remote, and voila... the remote stopped working as a HID. Now I need to comeup with proper configurations for my multimedia applications. Here comes a complete config file /etc/lirc/lircrc I came up with:

begin
    remote = Medion_MD8800
    prog = xine
    button = DVD_Menu
    config = RootMenu
    repeat = 0
    delay = 0
end

begin
    remote = Medion_MD8800
    prog = xine
    button = Up
    config = EventUp
    repeat = 0
    delay = 0
end

begin
    remote = Medion_MD8800
    prog = xine
    button = Down
    config = EventDown
    repeat = 0
    delay = 0
end

    prog = mplayer

    config = quit
    repeat = 0
    delay = 0
end

Mind that it enables remote control for xine, rythmbox, totem and mplayer (rythmobox, and totem must have the lirc support enabled to work, see Edit/Plugins). Enjoy.

Making a nice home video DVD

Video source: a Sony handycam (DCR-SR36) which produces mpeg/2 files.

Anticipated result: a nice DVD with rich menus.

How to do it?

First, I don't want to recode the movie clips, since it would degrade their quality. So I decided to use the mpegs straight from the video camera. If there is a need to clip such a video there is a nice tool to do that: avidemux.

There is also another nice tool for DVD authoring: DVDStyler - you can create a DVD menu interactively, add/rearrange clips etc. However it seems that it takes a great deal of time to come up with nice designs.

So I stumbled upon tovid. It's a bunch of scripts which allow to author a DVD in a non-interactive way, just generating appropriate menus, thumbnails etc. And here comes a bummer.... It turned out that there the mpegs from the videocam are not 100% compatible with the DVD format, and they require ... well not recoding but remuxing (remultiplexing). In order to do that I use a buch of commands:
ffmpeg -i $1 -vcodec copy -an -f rawvideo foo.mpv
ffmpeg -i $1 -vn -acodec copy -f mp2 foo.mp2
mplex -f 8 -o $2 foo.mpv foo.mp2
rm foo.mpv foo.mp2
Actually its a script, its good to save the above contents as an executable file, let's say: mpgfix, and then run it:
mpgfix file.mpg file-fixed.mpg
So file.mpg is remuxed and saved as file-fixed.mpg. You can save the file with the same name of course, then the original one will be replaced with the remuxed one. Mind that there is no quality loss here, no recoding.

And here comes the nice part DVD authoring, I just launch one of the tovid scripts (todisc):
todisc -loop 0 -chain-videos -menu-length 2 -thumb-shape normal -aspect 16:9 -menu-title "My DVD" -pal -files *.mpg -titles *.mpg -out DVD
And after a while in the DVD directory there is a complete authored DVD :) with nice animated menus. You can generate an ISO image out of it:
mksiofs -dvd-video -o dvd.iso DVD/
And you'll get a file dvd.iso which is a complete ISO image ready to burn. Enjoy.
