dvdvrconv

dvdvrconv extracts the vob files from the vro files on the DVD-VR format disc and converts them to mp4 files. dvdvrconv is also a wrapper for pixelb/dvd-vr.

For Windows users, I attached dvd-vr.exe for cygwin environment.

Execute the VRO file to mp4 conversion.

dvdvrconv -e or dvdvrconv --exec

Command options

>dvdvrconv -h
Usage: dvdvrconv [options]
    -v, --version                    Show version
    -i, --info                       Show file information
    -c, --config=FILE                Use YAML format FILE.
    -e, --exec                       Execute the VRO file to mp4 conversion.

Configure dvdvrconv

dvdvrconv reads default_dvdvrconv.yml in the current working directory as dvdvrconv's configuration file. It can contain the following settings:

vr_mangr_ifo
vr_movie_vro
dvd_vr_cmd
use_customize_title
base_dst_name
number_list

vr_mangr_ifo, vr_movie_vro

vr_mangr_ifo and vr_movie_vro specify the path to the dvd-ram disc. Drive D is assumed, if different you need to write its path.

windows default

vr_mangr_ifo: "/cygdrive/D/DVD_RTAV/VR_MANGR.IFO"
vr_movie_vro: "/cygdrive/D/DVD_RTAV/VR_MOVIE.VRO"

WSL(ubuntu) default

vr_mangr_ifo: "/mnt/d/DVD_RTAV/VR_MANGR.IFO"
vr_movie_vro: "/mnt/d/DVD_RTAV/VR_MOVIE.VRO"

dvd_vr_cmd

On Windows, you can use the included dvd-vr command.

On WSL(ubuntu), you can use the dvd-vr command that you have compiled yourself.

See the section below, "install dependent libraries for WSL(ubuntu)"

use_customize_title, base_dst_name, number_list

customize the title name of vob files.

If specify individual file names. Write "base_dst_name:" as an Array.

use_customize_title: 1
base_dst_name: ["name_one", "name_two"]
number_list: []

The resulting file name is => ["name_one", "name_two"]

If add a sequence number to the file name. Write "base_dst_name:" as String.

use_customize_title: 2
base_dst_name: "output_name_"
number_list: []

The resulting file name is => ["output_name_01", "output_name_02", ...]

If specify sequence numbers individually. Write "base_dst_name:" as String and Write "number_list" as an Array.

use_customize_title: 3
base_dst_name: "output_name_"
number_list: [12, 13, 14, 15]

The resulting file name is => ["output_name_12", "output_name_13", "output_name_14", "output_name_15"]

If do not want to customize the title name, Specify use_customize_title: no.

use_customize_title: no
base_dst_name: []
number_list: []

concat mode

Allow users to choose to concatenate or not concatenate titles with the same name.

When editing a title on a dvd-vr recorder (e.g., partial cut editing.), the title is split into multiple files.

Enabling "concat_mode" allows you to concatenate multiple split files into one.

If this option is not specified, the default setting is to concatenate titles of the same name.

concat_mode: true

On the other hand, you may not want to concatenate multiple titles with the same name on a dvd-vr disc. In this case, "concat_mode" can be disabled.

concat_mode: false

$ dvd-vr --help
Usage: dvd-vr [OPTION]... VR_MANGR.IFO [VR_MOVIE.VRO]
Print info about and optionally extract vob data from DVD-VR files.

If the VRO file is specified, the component programs are
extracted to the current directory or to stdout.

  -p, --program=NUM  Only process program NUM rather than all programs.

  -n, --name=NAME    Specify a basename to use for extracted vob files
                     rather than using one based on the timestamp.
                     If you pass `-' the vob files will be written to stdout.
                     If you pass `[label]' the names will be based on
                     a sanitized version of the title or label.

      --help         Display this help and exit.
      --version      Output version information and exit.
