vdr_files: the Video Disk Recorder Files

NAME
vdr_files - the Video Disk Recorder Files
DESCRIPTION
This page describes the formats of the various files vdr uses to store configuration data and recordings.

SYNTAX

CHANNELS The file channels.conf contains the channel configuration. Each line defines either a group delimiter or a channel. A group delimiter is a line starting with a ':' as the very first character, followed by arbitrary text. Example: :First group Group delimiters may also be used to specify the number of the next channel. To do this, the character '@' and a number must immediately follow the ':', as in :@201 First group The given number must be larger than the number of any previous channel (otherwise it is silently ignored). A group delimiter can also be used to just set the next channel's number, without an explicit delimiter text, as in :@201 Such a delimiter will not appear in the Channels menu. A channel definition is a line with channel data, where the fields are separated by ':' characters. Example: RTL Television,RTL;RTL World:12187:hC34M2O0S0:S19.2E:27500:163=2:104=deu;106=deu:105:0:12003:1:1089:0 The line number of a channel definition (not counting group separators, and based on a possible previous '@...' parameter) defines the channel's number in OSD menus and the timers.conf file. The fields in a channel definition have the following meaning (from left to right): Name The channel's name (if the name originally contains a ':' character it has to be replaced by '|'). Some TV stations provide a way of deriving a "short name" from the channel name, which can be used in situations where there is not much space for displaying a long name. If a short name is available for this channel, it follows the full name and is delimited by a comma, as in RTL Television,RTL:... If the short name itself would contain a comma, it is replaced with a '.'. Note that some long channel names may contain a comma, so the delimiting comma is always the rightmost one. If present, the name of the service provider or "bouquet" is appended to the channel name, separated by a semicolon, as in RTL Television,RTL;RTL World:... Frequency The transponder frequency (as an integer). For DVB-S this value is in MHz. For DVB-C and DVB-T it can be given either in MHz, kHz or Hz (the actual value given will be multiplied by 1000 until it is larger than 1000000). Parameters Various parameters, depending on whether this is a DVB-S, DVB-C or DVB-T channel. Each parameter consist of a key character, followed by an integer number that represents the actual setting of that parameter. The valid key characters, their meaning (and allowed values) are B Bandwidth (6, 7, 8) C Code rate high priority (0, 12, 23, 34, 35, 45, 56, 67, 78, 89, 910) D coDe rate low priority (0, 12, 23, 34, 35, 45, 56, 67, 78, 89, 910) G Guard interval (4, 8, 16, 32) H Horizontal polarization I Inversion (0, 1) L Left circular polarization M Modulation (2, 5, 6, 10, 11, 16, 32, 64, 128, 256, 998) O rollOff (0, 20, 25, 35) R Right circular polarization S delivery System (0, 1) T Transmission mode (2, 8) V Vertical polarization Y hierarchY (0, 1, 2, 4) Bandwidth: The bandwidth of the channel in MHz (DVB-T only). Code rate high priority: Forward Error Correction (FEC) of the high priority stream (DVB-T). For DVB-S/DVB-S2 this parameter specifies the inner FEC scheme. 12 = 1/2, 23 = 2/3, 34 = 3/4, ... Code rate low priority: Forward Error Correction (FEC) of the low priority stream (DVB-T only). If no hierarchy is used, set to 0. Guard interval: The guard interval value (DVB-T only): 4 = 1/4, 8 = 1/8, 16 = 1/16, 32 = 1/32. Inversion: Specifies whether the DVB frontend needs spectral inversion (DVB-T and DVB-C only). This is frontend specific, if in doubt, omit. Modulation: Specifies the modulation/constellation of the channel as follows: 2 QPSK (DVB-S, DVB-S2, DVB-T) 5 8PSK (DVB-S2) 6 16APSK (DVB-S2) 10 VSB8 (ATSC aerial) 11 VSB16 (ATSC aerial) 16 QAM16 (DVB-T) 64 QAM64 (DVB-C, DVB-T) 128 QAM128 (DVB-C) 256 QAM256 (DVB-C) Rolloff: The Nyquist filter rolloff factor for DVB-S (35) and DVB-S2 (35, 25, 20), 35 = 0.35, 25 = 0.25, 20 = 0.20, DVB-S/DVB- S2 default value is 0.35 Transmission mode: Number of DVB-T OFDM carriers, 8 = 8k, 2 = 2k. If in doubt, try 8k. Hierarchy: If set to 1, this transponder uses two streams, high priority and low priority. If in doubt, try 0 (off). (DVB-T only). Delivery System: The satellite delivery system (0 = DVB-S, 1 = DVB-S2). Polarization: Satellite antenna polarization. H = horizontal, V = vertical, R = circular right, L = circular left. The polarization parameters have no integer numbers following them. This is for compatibility with files from older versions and also to keep the DVB-S entries as simple as possible. The special value 999 is used for "automatic", which means the driver will automatically determine the proper value (if possible). An example of a parameter field for a DVB-T channel might look like this: B8C23D12G8M16T8Y0 An example of a parameter field for a DVB-C channel might look like this: C0M64 An example of a parameter field for a DVB-S channel might look like this: hC56M2O35S0 An example of a parameter field for a DVB-S2 channel might look like this: hC910M2O35S1 Plugins that implement devices that need their own set of parameters may store those in the parameters string in arbitrary format (not necessarily the "character/number" format listed above). The only condition is that the string may not contain colons (':') or newline characters. Source The signal source of this channel, as defined in the file sources.conf. Srate The symbol rate of this channel (DVB-S and DVB-C only). VPID The video PID (set to '0' for radio channels). If this channel uses a separate PCR PID, it follows the VPID, separated by a plus sign, as in ...:164+17:... If this channel has a video mode other than 0, the mode follows the pids, separated by an '=' sign, as in ...:164+17=27:... APID The audio PID (either one number, or several, separated by commas). If this channel also carries Dolby Digital sound, the Dolby PIDs follow the audio PIDs, separated by a semicolon, as in ...:101,102;103,104:... If certain audio PIDs broadcast in specific languages, the language codes for these can be appended to the individual audio or Dolby PID, separated by an '=' sign, as in ...:101=deu,102=eng;103=deu,104=eng:... Some channels broadcast two different languages in the two stereo channels, which can be indicated by adding a second language code, delimited by a '+' sign, as in ...:101=deu,102=eng+spa;103=deu,104=eng:... The audio type is appended with a separating '@' character, as in ...:101=deu@4,102=eng+spa@4,105=@4:... Note that if there is no language code, there still is the separating '=' if there is an audio type. TPID The teletext PID. Conditional access A hexadecimal integer defining how this channel can be accessed: 0000 Free To Air 0001...000F explicitly requires the device with the given number 0010...00FF reserved for user defined assignments 0100...FFFF specific decryption methods as broadcast in the data stream Values in the range 0001...00FF will not be overwritten, all other values will be automatically replaced by the actual CA system identifiers received from the data stream. If there is more than one CA system id broadcast, they will be separated by commas, as in ...:1702,1722,1801:... The values are in hex because that's the way they are defined in the "ETR 162" document. Leading zeros may be omitted. SID The Service ID of this channel. NID The Network ID of this channel. TID The Transport stream ID of this channel. RID The Radio ID of this channel (typically 0, may be used to distinguish channels where NID, TID and SID are all equal). A particular channel can be uniquely identified by its channel ID, which is a string that looks like this: S19.2E-1-1089-12003-0 The components of this string are the Source (S19.2E), NID (1), TID (1089), SID (12003) and RID (0) as defined above. The last part can be omitted if it is 0, so the above example could also be written as S19.2E-1-1089-12003). The channel ID is used in the timers.conf and epg.data files to properly identify the channels. If a channel has both NID and TID set to 0, the channel ID will use the Frequency instead of the TID. For satellite channels an additional offset of 100000, 200000, 300000 or 400000 is added to that number, depending on the Polarization (H, V, L or R, respectively). This is necessary because on some satellites the same frequency is used for two different transponders, with opposite polarization. TIMERS The file timers.conf contains the timer setup. Each line contains one timer definition, with individual fields separated by ':' characters. Example: 1:10:-T-----:2058:2150:50:5:Quarks & Co: The fields in a timer definition have the following meaning (from left to right): Flags The individual bits in this field have the following meaning: 1 the timer is active (and will record if it hits) 2 this is an instant recording timer 4 this timer uses VPS 8 this timer is currently recording (may only be up-to-date with SVDRP) All other bits are reserved for future use. Channel The channel to record from. This is either the channel number as shown in the on-screen menus, or a complete channel ID. When reading timers.conf any channel numbers will be mapped to the respective channel ids and when the file is written again, there will only be channel ids. Channel numbers are accepted as input in order to allow easier creation of timers when manually editing timers.conf. Also, when timers are listed via SVDRP commands, the channels are given as numbers. Day The day when this timer shall record. If this is a 'single-shot' timer, this is the date on which this timer shall record, given in ISO notation (YYYY-MM-DD), as in: 2005-03-19 For compatibility with earlier versions of VDR this may also be just the day of month on which this timer shall record (must be in the range 1...31). In case of a 'repeating' timer this is a string consisting of exactly seven characters, where each character position corresponds to one day of the week (with Monday being the first day). The character '-' at a certain position means that the timer shall not record on that day. Any other character will cause the timer to record on that day. Example: MTWTF-- will define a timer that records on Monday through Friday and does not record on weekends. Note that only letters may be used here, no digits. For compatibility with timers created with earlier versions of VDR, the same result could be achieved with ABCDE-- (which was used to allow setting the days with language specific characters). Since version 1.5.3 VDR can use UTF-8 characters to present data to the user, but the weekday encoding in the timers.conf file always uses single byte characters. The day definition of a 'repeating' timer may be followed by the date when that timer shall hit for the first time. The format for this is @YYYY-MM-DD, so a complete definition could look like this: MTWTF--@2002-02-18 which would implement a timer that records Monday through Friday, and will hit for the first time on or after February 18, 2002. This first day feature can be used to disable a repeating timer for a couple of days, or for instance to define a new Mon...Fri timer on Wednesday, which actually starts "Monday next week". The first day date given need not be that of a day when the timer would actually hit. Start A four digit integer defining when this timer shall start recording. The format is hhmm, so 1430 would mean "half past two" in the afternoon. Stop A four digit integer defining when this timer shall stop recording. The format is the same as for the start time. Priority An integer in the range 0...99, defining the priority of this timer and of recordings created by this timer. 0 represents the lowest value, 99 the highest. The priority is used to decide which timer shall be started in case there are two or more timers with the exact same start time. The first timer in the list with the highest priority will be used. This value is also stored with the recording and is later used to decide which recording to remove from disk in order to free space for a new recording. If the disk runs full and a new recording needs more space, an existing recording with the lowest priority (and which has exceeded its guaranteed lifetime) will be removed. If all available DVB cards are currently occupied, a timer with a higher priority will interrupt the timer with the lowest priority in order to start recording. Lifetime The guaranteed lifetime (in days) of a recording created by this timer. 0 means that this recording may be automatically deleted at any time by a new recording with higher priority. 99 means that this recording will never be automatically deleted. Any number in the range 1...98 means that this recording may not be automatically deleted in favour of a new recording, until the given number of days since the start time of the recording has passed by. File The file name this timer will give to a recording. If the name contains any ':' characters, these have to be replaced by '|'. If the name shall contain subdirectories, these have to be delimited by '~' (since the '/' character may be part of a regular programme name). The special keywords TITLE and EPISODE, if present, will be replaced by the title and episode information from the EPG data at the time of recording (if that data is available). If at the time of recording either of these cannot be determined, TITLE will default to the channel name, and EPISODE will default to a blank. Auxiliary data An arbitrary string that can be used by external applications to store any kind of data related to this timer. The string must not contain any newline characters. If this field is not empty, its contents will be written into the info file of the recording with the '@' tag. SOURCES The file sources.conf defines the codes to be used in the Source field of channels in channels.conf and assigns descriptive texts to them. Example: S19.2E Astra 1 Anything after (and including) a '#' character is comment. The first character of the code must be one of A ATSC C Cable S Satellite T Terrestrial and is followed by further data pertaining to that particular source. In case of Satellite this is the orbital position in degrees, followed by E for east or W for west. Plugins may define additional sources, using other characters in the range 'A'...'Z'. DISEQC The file diseqc.conf defines the DiSEqC control sequences to be sent to the DVB-S card in order to access a given satellite position and/or band. Example: S19.2E 11700 V 9750 t v W15 [E0 10 38 F0] W15 A W15 t Anything after (and including) a '#' character is comment. The first word in a parameter line must be one of the codes defined in the file sources.conf and tells which satellite this line applies to. Following is the "switch frequency" of the LNB (slof), which is the transponder frequency up to which this entry shall be used; the first entry with an slof greater than the actual transponder frequency will be used. Typically there is only one slof per LNB, but the syntax allows any number of frequency ranges to be defined. Note that there should be a last entry with the value 99999 for each satellite, which covers the upper frequency range. The third parameter defines the polarization to which this entry applies. It can be either H for horizontal or V for vertical. The fourth parameter specifies the "local oscillator frequency" (lof) of the LNB to use for the given frequency range. This number will be subtracted from the actual transponder frequency when tuning to the channel. The rest of the line holds the actual sequence of DiSEqC actions to be taken. The code letters used here are t 22kHz tone off T 22kHz tone on v voltage low (13V) V voltage high (18V) A mini A B mini B Wnn wait nn milliseconds (nn may be any positive integer number) [xx ...] hex code sequence (max. 6) There can be any number of actions in a line, including none at all - in which case the entry would be used only to set the LOF to use for the given frequency range and polarization. By default it is assumed that every DVB-S device can receive every satellite. If this is not the case in a particular setup, lines of the form 1 2 4: may be inserted in the diseqc.conf file, defining the devices that are able to receive the satellites following thereafter. In this case, only the devices 1, 2 and 4 would be able to receive any satellites following this line and up to the next such line, or the end of the file. Devices may be listed more than once. REMOTE CONTROL KEYS The file remote.conf contains the key assignments for all remote control units. Each line consists of one key assignment in the following format: name.key code where name is the name of the remote control (for instance KBD for the PC keyboard, RCU for the home-built "Remote Control Unit", or LIRC for the "Linux Infrared Remote Control"), key is the name of the key that is defined (like Up, Down, Menu etc.), and code is a character string that this remote control delivers when the given key is pressed. KEY MACROS The file keymacros.conf contains user defined macros that will be executed whenever the given key is pressed. The format is macrokey [@plugin] key1 key2 key3... where macrokey is the key that shall initiate execution of this macro and can be one of Up, Down, Ok, Back, Left, Right, Red, Green, Yellow, Blue, 0...9 or User1...User9. The rest of the line consists of a set of keys, which will be executed just as if they had been pressed in the given sequence. The optional @plugin can be used to automatically select the given plugin. plugin is the name of the plugin, exactly as given in the -P option when starting VDR. There can be only one @plugin per key macro. For instance User1 @abc Down Down Ok would call the main menu function of the "abc" plugin and execute two "Down" key presses, followed by "Ok". Note that the color keys will only execute their macro function in "normal viewing" mode (i.e. when no other menu or player is active). The User1...User9 keys will always execute their macro function. There may be up to 15 keys in such a key sequence. FOLDERS The file folders.conf contains the definitions of folders that can be used in the "Edit timer" menu. Each line contains one folder definition. Leading whitespace and everything after and including a '#' is ignored. A line ending with '{' defines a sub folder (i.e. a folder that contains other folders), and a line consisting of only '}' ends the definition of a sub folder. Example: Daily { News Soaps } Archive { Movies Sports Sci-Fi { Star Trek U.F.O. } } Comedy Science Note that these folder definitions are only used to set the file name under which a timer will store its recording. Changing these definitions in any way has no effect on existing timers or recordings. COMMANDS The file commands.conf contains the definitions of commands that can be executed from the vdr main menu's "Commands" option. Each line contains one command definition in the following format: title : command where title is the string that will be displayed in the "Commands" menu, and command is the actual command string that will be executed when this option is selected. The delimiting ':' may be surrounded by any number of white space characters. If title ends with the character '?', there will be a confirmation prompt before actually executing the command. This can be used for commands that might have serious results (like deleting files etc) to make sure they are not executed inadvertently. Everything following (and including) a '#' character is considered to be comment. You can have nested layers of command menus by surrounding a sequence of commands with '{'...'}' and giving it a title, as in My Commands { First list { Do something: some command Do something else: another command } Second list { Even more: yet another command So much more: and yet another one } } Command lists can be nested to any depth. By default the menu entries in the "Commands" menu will be numbered '1'...'9' to make them selectable by pressing the corresponding number key. If you want to use your own numbering scheme (maybe to skip certain numbers), just precede the titles with the numbers of your choice. vdr will suppress its automatic numbering if the first entry in commands.conf starts with a digit in the range '1'...'9', followed by a blank. In order to avoid error messages to the console, every command should have stderr redirected to stdout. Everything the command prints to stdout will be displayed in a result window, with title as its title. Examples: Check for new mail?: /usr/local/bin/checkmail 2>&1 CPU status: /usr/local/bin/cpustatus 2>&1 Disk space: df -h | grep '/video' | awk '{ print 100 - $5 "% free"; }' Calendar: date;echo;cal Note that the commands 'checkmail' and 'cpustatus' are only examples! Don't send emails to the author asking where to find these ;-) The '?' at the end of the "Check for new mail?" entry will prompt the user whether this command shall really be executed. RECORDING COMMANDS The file reccmds.conf can be used to define commands that can be applied to the currently highlighted recording in the "Recordings" menu. The syntax is exactly the same as described for the file commands.conf. When executing a command, the directory name of the recording will be appended to the command string, separated by a blank and enclosed in single quotes. SVDRP HOSTS The file svdrphosts.conf contains the IP numbers of all hosts that are allowed to access the SVDRP port. Each line contains one IP number in the format IP-Address[/Netmask] where IP-Address is the address of a host or a network in the usual dot separated notation (as in 192.168.100.1). If the optional Netmask is given only the given number of bits of IP-Address are taken into account. This allows you to grant SVDRP access to all hosts of an entire network. Netmask can be any integer from 1 to 32. The special value of 0 is only accepted if the IP-Address is 0.0.0.0, because this will give access to any host (USE THIS WITH CARE!). Everything following (and including) a '#' character is considered to be comment. Examples: 127.0.0.1 # always accept localhost 192.168.100.0/24 # any host on the local net 204.152.189.113 # a specific host 0.0.0.0/0 # any host on any net (USE WITH CARE!) SETUP The file setup.conf contains the basic configuration options for vdr. Each line contains one option in the format "Name = Value". See the MANUAL file for a description of the available options. THEMES The files themes/<skin>-<theme>.theme in the config directory contain the color theme definitions for the various skins. In the actual file names <skin> will be replaced by the name if the skin this theme belongs to, and <theme> will be the name of this theme. Each line in a theme file contains one option in the format "Name = Value". Anything after (and including) a '#' character is comment. The definitions in a theme file are either colors or a description. Colors are in the form clrTitle = FF123456 where the name (clrTitle) is one of the names defined in the source code of the skin that uses this theme, through the THEME_CLR() macro. The value (FF123456) is an eight digit hex number that consist of four bytes, representing alpha (transparency), red, green and blue component of the color. An alpha value of 00 means the color will be completely transparent, while FF means it will be opaque. An RGB value of 000000 results in black, while FFFFFF is white. A description can be given as Description = Shades of blue and will be used in the Setup/OSD menu to select a theme for a given skin. The description should give the user an idea what this theme will be like (for instance, in the given example it would use various shades of blue), and shouldn't be too long to make sure it fits on the Setup screen. The default description always should be given in English. If you want, you can provide language specific descriptions as Description.eng = Shades of blue Description.ger = Blaut"
