CDEMU(1) General Commands Manual CDEMU(1) NAME cdemu - a simple command-line CDEmu client SYNOPSIS cdemu [options] DESCRIPTION This is cdemu, a command-line client for controlling CDEmu daemon. It is part of the cdemu suite, a free, GPL CD/DVD-ROM device emulator for linux. It provides a way to perform the key tasks related to controlling the CDEmu daemon, such as loading and unloading devices, displaying devices' status and retrieving/setting devices' debug masks. When connecting to daemon, cdemu client can use either session or system bus. By hard-coded default, it uses system bus. The default bus to be used can be specified via /etc/cdemu-client.conf or ~/.cdemu- client file; for more information, please read README file. The default can be overridden using --bus option. ENCRYPTED IMAGES SUPPORT CDEmu daemon offers support for encrypted images. When password is required to load an image, cdemu-client will prompt for it and then send it to daemon. NOTE, HOWEVER, THAT THE PASSWORD IS SENT OVER D-BUS IN A PLAIN STRING FORM, WITHOUT ANY PROTECTION. OPTIONS -h --help Displays the help message. If command is specified, help message with synopsis and description for that command is displayed. -v --version Prints version info and exits. -b --bus Sets the D-BUS bus type to use for connection. Valid values are session and system. If no bus is specified, the default bus is used. COMMANDS load [parser-parameters] [...] Loads the device; device is the number of the desired device, or any. If any is used, then the client will attempt to load the image into the first empty device it finds (provided there is one available). filename is the image filename. For multi-file images, multiple filenames can be provided. The following optional parser parameters can be passed when trying to load the image (whether they are supported by a particular parser or not depends on the parser implementation): --encoding Allows an encoding for text-based image format (such as CUE) to be specified. This might be needed if the image descriptor file contains non-ASCII characters and does not use Unicode. create-blank [options] --writer_id= Creates blank recordable disc in the specified device. device is the number of the desired device, or any. If any is used, then the client will attempt to load the image into the first empty device it finds (provided there is one available). image_file is the image filename/basename. A valid writer-id must also be provided. Other valid options are: --medium-type Sets the blank medium type. Valid values are: cdr74, cdr80, cdr90, cdr99 and dvd+r. --param="writer.parameter_id=parameter_value" Allows user to pass additional image writer parameters. parameter_id must be a valid parameter ID from image writer's parameter sheet, prefixed by "writer.". unload Unloads the device; device is the number of the desired device, or all. status Displays devices' status add-device Creates another virtual device remove-device Removes the last virtual device device-mapping Displays device mapping information daemon-debug-mask [new-value] Displays/sets daemon debug mask; device is the number of the desired device, or all. new-value is the new debug mask value. If this argument is omitted, current debug mask is displayed. The list of supported debug mask identifiers and values can be obtained with enum-daemon-debug-masks command. The new-value can be either a single numeric value (e.g, 0x03), a string of numeric values separated by pipe character (e.g., "0x01|0x02"), or a string of identifiers separated by pipe character (e.g., "DAEMON_DEBUG_DEVICE|DAEMON_DEBUG_MMC"). library-debug-mask [new-value] Displays/sets library debug mask; device is the number of the desired device, or all. new-value is the new debug mask value. If this argument is omitted, current debug mask is displayed. The list of supported debug mask identifiers and values can be obtained with enum-library-debug-masks command. The new-value can be either a single numeric value (e.g, 0x03), a string of numeric values separated by pipe character (e.g., "0x01|0x02"), or a string of identifiers separated by pipe character (e.g., "MIRAGE_DEBUG_PARSER|MIRAGE_DEBUG_DISC"). dpm-emulation [new-value] Displays/sets DPM emulation flag. device is the number of the desired device, or all. new-value is the new value to be set. If this argument is omitted, currently set value is displayed. tr-emulation [new-value] Displays/sets transfer rate emulation flag. device is the number of the desired device, or all. new-value is the new value to be set. If this argument is omitted, currently set value is displayed. bad-sector-emulation [new-value] Displays/sets bad sector emulation flag. device is the number of the desired device, or all. new-value is the new value to be set. If this argument is omitted, currently set value is displayed. dvd-report-css [new-value] Report the loaded DVD as CSS-encrypted. device is the number of the desired device, or all. new-value is the new value to be set. If this argument is omitted, currently set value is displayed. This flag influences the generation of fake Disc Structure 0x01, and as such works only with images of DVD videos that do not provide this information (most images, with exception of perhaps mds/mdf, don't). Enabling this option allows images of CSS- encrypted DVDs (e.g. created using 'dd' or 'readcd' without running through a CSS decryption step when creating the image) to be played by a deCSS-enabled Linux media player. device-id [new-vendor-id] [new-product-id] [new-revision] [new-vendor-specific] Displays/sets device ID. device is the number of the desired device. new-vendor-id is the new vendor ID string to be set (8 characters max). new-product-id is the new product ID string to be set (16 characters max). new-revision is the new revision string to be set (4 characters max). new-vendor-specific is the new vendor-specific string to be set (20 characters max). If new values are omitted, currently set values are displayed. enum-parsers Enumerates supported image parsers. enum-writers Enumerates supported image writers. enum-filter-streams Enumerates supported filter streams. enum-daemon-debug-masks Enumerates supported daemon debug masks. enum-library-debug-masks Enumerates supported library debug masks. enum-writer-parameters Retrieves and displays parameters sheet for specified image writer. version Displays version information EXAMPLES Loading a single image to first device: cdemu load 0 ~/image.mds Loading multiple-file image to first device: cdemu load 0 ~/session1.toc ~/session2.toc ~/session3.toc Loading a text-based image in non-ASCII/non-Unicode encoding: cdemu load 0 ~/image.cue --encoding=windows-1250 Loading a raw image of a CSS-encrypted DVD created by 'dd', so it can be played by mplayer: cdemu load 0 ~/image.iso cdemu dvd-report-css 0 1 Creating a blank recordable disc: DVD+R SL with ISO image writer: cdemu create-blank --writer-id=WRITER-ISO --medium-type=dvd+r 0 ~/output-image.iso Creating a blank recordable disc: 80-minute CD-R with TOC image writer, with additional writer parameters: cdemu create-blank --writer-id=WRITER-TOC --medium-type=cdr80 --param="writer.write_raw=1" --param="writer.write_subchannel=1" 0 ~/output-image.toc Unloading first device: cdemu unload 0 Displaying device status: cdemu status Adding another device: cdemu add-device Removing the last device: cdemu remove-device Displaying device mapping information: cdemu device-mapping Setting daemon debug mask for the first device: cdemu daemon-debug-mask 0 0x01 Setting daemon debug mask for the first device (composite): cdemu daemon-debug-mask 0 "0x01|0x02" Setting daemon debug mask for the first device (composite, by name): cdemu daemon-debug-mask 0 "DAEMON_DEBUG_DEVICE|DAEMON_DEBUG_MMC" Obtaining library debug mask for the first device: cdemu library-debug-mask 0 Disabling DPM emulation on all devices: cdemu dpm-emulation all 0 Enabling transfer rate emulation on first device: cdemu tr-emulation 0 1 Enabling bad sector emulation on first device: cdemu tr-emulation 0 1 Changing device ID of first device: cdemu device-id 0 "MyVendor" "MyProduct" "1.0.0" "Test device ID" Enumerating supported image parsers: cdemu enum-parsers Enumerating supported image writers: cdemu enum-writers Enumerating supported filter streams: cdemu enum-filter-streams Enumerating supported daemon debug masks: cdemu enum-daemon-debug-masks Enumerating supported library debug masks: cdemu enum-library-debug-masks Obtaining parameter sheet for TOC image writer: cdemu enum-writer-parameters WRITER-TOC Displaying daemon and library version: cdemu version AUTHORS Rok Mandeljc CDEmu project's web page: http://cdemu.sourceforge.net CDEmu project's mailing list: cdemu-devel@lists.sourceforge.net July 14, 2013 CDEMU(1)
