Introduction

Every so often I find myself in looking through the ex-rental DVD "bargain bin".
Quite often I find something I consider a bargain. However, the experience of 
watching an ex-rental DVD is typically ruined by the various trailers and 
marketing guff at the start which you can't skip. My wife hates that stuff, and 
I love my wife, so I routinely rip the main feature of newly acquired ex-rental 
DVD movies so we can avoid the marketing crap.

I also run a DLNA server and I want to import all my DVDs. Ripping them helps 
reduce the amount of storage I will require. MPEG2-PS and MPEG2-TS files are 
compatible with my PS3 which is the client to my DLNA server.

As a solution to the above I created this script, which can extract the main 
feature from a DVD video, allowing the user to select one audio stream and one
subtitle stream. 

Optionally the video stream can be shrunk. In MPEG-2 PS mode the video is 
requantised and in MPEG-2 TS mode the video is re-encoded as H.264. Requantising
is faster but can introduce artifacting. H.264 encoding is slower, but produces 
very good quality.

Some things to be aware of:

  - MPEG-2 PS is the default mode of operation.
  - Subtitles are only supported in MPEG-2 PS mode.
  - MPEG-2 PS files created by this script are DVD compliant.
  - ISO files created by this script will preserve the chapters from the 
    original DVD.
  - The PS3 can only play DTS audio in MPEG-2 PS streams when they have been 
    authored to DVD.
  - The PS3 can only play subtitles in MPEG-2 PS streams when they have been 
    authored to DVD.    
  - The PS3 can't play DTS audio in MPEG-2 TS streams therefore this script 
    will transcode DTS to AC3 when in MPEG-2 TS mode.

Usage
  /home/martin/Source/DVD-to-MPG/DVD-to-MPG.sh /dev/dvd [--iso] [--m2ts] [--2pass] [--keep] [--shrink] [--help]

You can also pass the following optional parameters
  --iso    : Create an ISO image of the ripped DVD.    (Implies MPEG-2 PS)
  --m2ts   : Create a MPEG-2 TS file with H.264 video. (Subtitles not supported)
  --2pass  : Enable 2 pass encoding for the H.264 video if MPEG-2 TS is selected.
  --keep   : Keep the intermediate files produced during the rip.
  --shrink : Shrink the video stream so that:
               * MPEG-2 PS fits on a single layer DVD-/+R disk.
               * MPEG-2 TS is encoded as H.264 either using one pass CRF 16
                 or two pass at a target bitrate of 2816.
  --help   : This help.

The resulting .ISO can be tested with gmplayer or vlc to check that the 
video, audio, subtitle, chapters, etc are also working correctly.

 gmplayer -dvd-device DVD_VIDEO.iso dvd://
 vlc DVD_VIDEO.iso

The resulting MPEG-2 PS and MPEG-2 TS files can also be tested/viewed using 
mplayer or vlc.

Known Limitations

 - DVDs with ARccOS or other intentional sector corruption are not supported.
 - Multi-angle titles are not properly supported yet. 
 - No user selection of which title to rip. Defaults to the longest title.
 - Rips one video, one audio stream and one subtitle stream from the source DVD.
