NAME

       ncplayer - Render images and video to a terminal

SYNOPSIS

       ncplayer [-h] [-V] [-q] [-d delaymult] [-l loglevel] [-b blitter] [-s scalemode] [-k] [-L]
       [-t seconds] [-n] [-a color] files

DESCRIPTION

       ncplayer uses a multimedia-enabled Notcurses to render images and videos  to  a  terminal.
       By  default,  stretch-type  scaling  is  used to fill the rendering area, and the highest-
       quality blitter available is employed.

OPTIONS

       -d delaymult: Apply a non-negative rational multiplier to the delayscale.  Only applies to
       multiframe media such as video and animated images.  Not supported with -k.

       -t  seconds: Delay seconds after each file.  If this option is used, the "press any key to
       continue" prompt will not be displayed.  seconds may be any non-negative number.

       -l loglevel: Log between everything (loglevel 7) and nothing (loglevel 0) to stderr.

       -s scalemode: Scaling mode, one of none, hires, scale, scalehi, or stretch.

       -b blitter: Blitter, one of ascii, half, quad, sex, braille, or pixel.

       -m margins: Define rendering margins (see below).

       -L: Loop frames until a key is pressed.  Not supported with -k.

       -k: Use direct mode (see notcurses_direct(3)).  This will have the effect of  leaving  the
       output  on-screen  after  program exit, and generating it inline (rather than clearing the
       screen and placing it at the top).  Not supported with -L or -d.

       -q: Print neither frame/timing information along the top of the  screen,  nor  the  output
       summary on exit.

       -a: Treat color as if it were transparent.

       -n: Use non-interpolative scaling.  The result is usually less pleasing to the eye, but it
       doesn't introduce new colors.

       -V: Print the program name and version, and exit with success.

       -h: Print help information, and exit with success.

       files: Select which files to render, and what order to render them in.

       Default margins are all 0 and default scaling is stretch.  The full  rendering  area  will
       thus be used.  Using -m, margins can be supplied.  Provide a single number to set all four
       margins to the same value, or four comma-delimited values for the top, right, bottom,  and
       left  margins  respectively.   Top, right, and bottom margins are ignored when -k is used.
       Negative margins are illegal.

       Scaling mode stretch resizes the object  to  match  the  target  rendering  area  exactly.
       Unless  a  blitter  is  specified with -b, stretch will use the highest-resolution blitter
       available.  scale resizes the object so that the longer edge  of  the  rendering  area  is
       matched  exactly,  and  the other edge is changed to maintain aspect ratio.  none uses the
       original image size.  Both scale and none aim for a 1:1 aspect ratio, and will thus prefer
       half  to  quad,  sex,  or  braille.   scalehi and hires use the highest-resolution blitter
       available.

       Blitters can  be  selected  at  runtime  by  pressing  '0'  through  '6'.   NCBLIT_DEFAULT
       corresponds  to  '0'.   The  various  blitters are described in notcurses_visual(3).  If a
       blitter cannot be used in the current environment, the current blitter will be retained.

       Multiframe media can be paused with space.  Press space (or any other  valid  control)  to
       resume.

NOTES

       If you're looking for a fast, inline image viewer for the shell, try using ncplayer -k -t0
       -q.

       Optimal display requires a terminal advertising the rgb terminfo(5)  capability,  or  that
       the  environment variable COLORTERM is defined to 24bit (and that the terminal honors this
       variable), along with a fixed-width font with good coverage of the Unicode  Block  Drawing
       Characters.

BUGS

       Direct  mode  is  kinda  fundamentally  suboptimal  for  multiframe  media, and is not yet
       supported with -L nor -d.  Top, right, and bottom margins are ignored without warning when
       using direct mode.
