- out_file=template
- - filename template filename for tags with parameter save=auto;
- out_file_jpegs=template

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)

- url of the file or stream;
- src

- 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

- save=ask
- to always ask the file name for recording;
- save=auto

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
