1 VLM: VideoLAN (Media) Manager
3 VLM is a little media manager originally designed to launch multiple
4 streams with only one VLC.
8 You can launch it as a common interface.
9 Default port is 4212, default password is "admin". These are common
10 options of the interface, so you can modify them as you wish.
11 Once you are connected on telnet interface, just type a command
15 You can launch it as a common interface
17 Access it from http://127.0.0.1:8080/vlm.html
21 A media is composed with a list of inputs (the videos and audios you
22 want to stream), an output (where you want to stream them), and some
23 options. It is very close to a TV program, or channel: it is
24 launched, stopped, paused by the administrator (or a schedule), may
25 be repeated several times etc.
28 A Schedule is a script with a date. When the current date is the
29 schedule date, the script is launched. There are of course other
30 options, like a period, a number of repetitions, etc. for the
31 schedule to be launched several times (or endlessly) automatically.
33 III - Command line syntax:
34 Note: an element is a media or a schedule.
37 Displays an exhaustive commmand lines list.
39 new (name) broadcast|schedule [properties]
40 Creates a new element. You must specify if a broadcast media, or
41 a schedule (there is no default type).
42 "media" and "schedule" are reserved names, and element names
44 Properties are optional: you can use the "setup" command to set
46 setup (name) (properties)
47 Set the property of the (name) element.
48 See Properties section for more information.
49 show [(name)|media|schedule]
50 Displays current element states and configurations.
51 "show (name)" displays all information about the (name) element.
52 "show media" displays a summary of medias states.
53 "show schedule" displays a summary of schedules states.
54 "show" is a the same as "show media show schedule".
55 del (name)|all|media|schedule
56 Destroys an element, or a group of elements. If the element is
57 at a non-stop state, it stops it (media or schedule).
58 "del (name)" destroys the (name) element.
59 "del all" destroys all elements.
60 "del media" destroys all medias.
61 "del schedule" destroys all schedules.
62 control (name) [instance_name] (command)
63 Changes the state of the (instance_name) instance of (name) media.
64 If (instance_name) is not specified, the control command affects the
66 See Commands section for more information.
68 Saves all media and schedule configurations in the (config_file)
69 configuration file. the "save" command overwrites the file if it
70 already exists. States (playing, paused, stop) are not saved.
71 See Configuration File section for more information.
73 Loads the (config_file) configuration file.
74 See Configuration File section for more information.
77 Note: except the "append" property, all property can be followed by
78 another one, recursively.For example:
79 "setup pouet input file://arf.avi output udp:127.0.0.1 enabled loop"
80 is a valid command line.
81 Media Properties Syntax:
83 Adds (input_name) at the end of the media input list.
84 inputdel (input_name)|all
85 Deletes (input_name) or all items from the media input list.
86 inputdeln (input_number)
87 Deletes the item #(input_number) from the media input list.
89 Defines the output of the media.
90 The syntax is equivalent to the ":sout=..." option , but you
91 do not have to put the ":sout=" string.
92 option (option_name)[=value]
93 Adds the (option_name) to the media option list.
94 The syntax is equivalent to the ":(option)=..." option , but you
95 do not have to put the ":" string.
96 Options are global: they are applied to all inputs of the
99 Enable or Disable the media.
100 If a media is disabled, it can not be streamed, paused,
101 launched by a schedule.
103 Used for broadcast only.
104 If a media with "loop" option receives the "play" command
105 and finally finishes to play the last input of the list, it
106 will automatically restart to play the input list.
108 Schedule Properties Syntax:
110 A disabled schedule will never be launched.
112 Adds a command to the command line list.
113 The command line can be every command the VLM can understand.
114 Note: the rest of the line will be considered as part of the
115 command line. You cannot put another option after the
117 date (year)/(month)/(day)-(hour):(minutes):(seconds)|now
118 Specifies the first date the schedule should be launched.
119 the date must have the explicit form:
120 (year)/(month)/(day)-(hour):(minutes):(seconds)
121 For example: 2004/03/07-12:42:30
122 If you write "now" instead of a date, the schedule will be
123 launch as soon as possible (as soon as it is enabled), and
124 the current date will be used as the first date of the
125 schedule (for repeating).
126 period (years)/(months)/(days)-(hours):(minutes):(seconds)
127 Specifies the period of time a schedule must wait for
128 launching itself another time.
129 For now, the period has a very close syntax to a date:
130 months are considered as 30 days
131 years are considered as 12 months.
132 If a period is specified without a "repeat", it will be
134 repeat (number_of_repetitions)
135 Specifies the number of times the schedule has to be launch
136 again. For example, if a schedule has "repeat 3", it will be
139 3) Control Commands Syntax:
141 Starts a broadcast media. The media begins to launch the first
142 item of the input list, then launches the next one, and so on
145 Puts the broadcast media in paused status.
147 Stops the broadcast media.
149 Seeks in the current playing item of input list.
151 IV - The configuration file
152 A VLM configuration file is very simple: it is only a list of command
153 lines: one line corresponds to one command line.
154 If you want to create a configuration file, just edit a text file and
155 type a list of VLM command lines. But beware of recursive calls: you
156 can put a "load (file)" command in a configuration file, so for
157 example, if you put a "load pouet" in a pouet file, and you launch the
158 "load pouet" command, then pouet will be loaded endlessly, and VLC
159 will crash (at least).
160 The load command converts the medias and schedules configurations into
161 command lines, and writes them into a file.
162 Any line where the first non white space character is a '#' is considered
