[mythtv-users] wrapper script for archived video

[Markus Döhla]

Hi all!

I archive my recordings using nuvexport to transcode to xvid and then burn the files to dvd.
So I want to watch these data-dvds from my frontend and tinkered the following:
It mounts the cd/dvd to the dvd-rom and checks if there's an VIDEO_TS folder available.
If yes, then it starts xine to play the inserted disc as video-dvd.
If no, it writes a playlist to the userhome and plays it with mplayer.


1) Wrapper script dvd.sh.

You probably have to change some of the variables/paths to fit your box.
I'm on Gentoo, so you probably have to change "/dev/dvd" to something else like "/dev/cdrom" or "/dev/cdroms/cdrom0".

#========================================================================

#!/bin/bash

  TONUL=">/dev/null 2>&1"

  MNTPT="/mnt/cdrom"
  DEVIC="/dev/dvd"
  PLIST="${HOME}/playlist.mply"
  XINEB="/usr/bin/xine"
  MPLAY="/usr/bin/mplayer -ac hwac3, -ao alsa:device=spdif -vo xv -fs -zoom -really-quiet -playlist"

  sudo mount ${DEVIC} ${MNTPT}
  if [ $? -ne 0 ]
  then
    sudo umount ${MNTPT}
    exit 1
  fi

  ISDVD=`ls ${MNTPT} | grep VIDEO_TS`

  if [ -n "${ISDVD}" ]
  then
    sudo umount ${MNTPT}
    ${XINEB} -pfh --no-splash dvd://
  else
    rm -f ${PLIST} ${TONUL}
    find /mnt/cdrom -type f >> ${PLIST}
    ${MPLAY} ${PLIST}
    sudo umount ${MNTPT}
  fi

#========================================================================

If executed as root, you should remove the leading "sudo" in some lines and skip to step 3).


2) If executed as normal user, you have to add your user/group to sudoers.

This is done by:

# visudo

add this lines:
<your_mythtv_user>  <your_hostname>=NOPASSWD:/usr/bin/sudo
%users  ALL=/bin/mount /dev/dvd /mnt/cdrom, /bin/umount /mnt/cdrom


3) To profit from mplayers ability to browse through the playlist you have to add this to your ~/.lircrc:

#========================================================================

begin
  prog = mplayer
  button = Replay
  config = pt_step -1
  repeat = 1
end

begin
  prog = mplayer
  button = Skip
  config = pt_step +0
  repeat = 1
end

#========================================================================

This adds functionality to the skip+/- buttons to the Hauppauge grey remote.
Like everything else you will probably have to fit it to your needs :)

Hope this helps somebody!
