== Configuration ==
The plugin uses "~/.mozilla/genres/genres.conf" or "/etc/genres.conf" as main config file.
Options for mplayer, mencoder and ElphelOgm are stored in the config file "~/.mozilla/genres/mplayer.conf", which is used by mplayer.pl control script.
The files can contain shell-like comments.
=== options in genres.conf ===
;mozillastreams={1|0} :- use or not mozilla streams (and cache) for http, https and ftp;
;debuglevel={1|0} :- enable or disable the debug output;
;background={-1|0|1} :- object color while loadining: 0 - black, 1 - white, -1 - mozilla default (gray).

=== options in mplayer.conf ===
;out_file_once=template :- filename template filename;
;out_file=template :- filename template filename for tags with parameter save=auto;
;out_file_jpegs=template :- filename template for tags with thesaveformat=jpeg;
;out_file_jpegs_auto=template :- same for save=auto and saveformat=jpeg;
;vo={x11,xv} :- video output driver (see man mplayer about -vo option);
;ao={arts,esd,alsa,oss} :- audio output driver (see man mplayer about -ao option);
;not_ask={1|0} :- not show file save dialog for tags with save=auto parameter;
;not_ask_jpegs={1|0} :- same for saveformat=jpeg;
;frames=number :- frames per file limit for recording (output will be splitted).

== Usage in Javascript ==
=== Static tag parameters ===
;lowres: decimation for accelerated DCT (0-3);
;width: width of the object window;
;loop: number of iterations of the playback (0 or nothing is infinite);
;fps: frame frequency;
;frameskip : skip n frames after one saved (only for rtp/mjpeg and ElphelOgm);
;framedelay : a number of fully received frames delayed in the buffer (only for rtp/mjpeg and ElphelOgm);
;rotate : the rotation angle of the image clockwise in degrees (0|90|180|240)
;mirror : mirror-symmetry mapping relative to vertical axis (true|false)
;flip : the same relative to horizontal (true|false); simultaneous setting of flip and mirror is equivalent to rotate=180
;saveformat=jpeg|ogm|avi : format for video recording (jpeg, ogm is only for rtp/mjpeg and ElphelOgm)

=== Dynamic variables (can also be used as the parameters of tags) ===
;href: url of the file or stream;
;src: as yet simply another name for href.
;pause=1 or play=0: to pause player;
;pause=0 or play=1: to continue playback;
;filepos=sec : go to time or percent specifed, maybe not works if mplayer is not support seeking for the current file;
;framestep=anything : show next frame and pause (for step-by-step view);
;run=1: to start player again if it was terminated (by error or end of file);
;run=0: to terminate player;
;save: to run mencoder or ElphelOgm as recorder instead of mplayer;
:;save=ask: to always ask the file name for recording;
:;save=auto: not to ask if user sets it in dialog

=== Status variables ===
This the output from mplayer or mencoder.
Now strings simply are split into two parts on the first of the symbols '=' or ':'.
The left part becomes a name of the variable (gaps and nonlatin letters are removed) and the right part is a value.
;frame: the message from mplayer/mencoder about the last frame;
;error: last error message;
;FATAL: fatal error message from mplayer;
Other variables are possible but they are not used as yet.
;run: special variable, the state of player process: 0 - not running, 1 - running;
;pause, play: it is analogous - the pause state.

=== Callback functions ===
On the arrival of data from a player it is transferred to the object variables and it becomes accessible from javascript.
In this case if it is assigned the function with the corresponding name "on
