ncplayer(1) ncplayer(1) 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 em- ployed. OPTIONS -d delaymult: Apply a non-negative rational multiplier to the de- layscale. 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, oct, 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 ef- fect 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 mar- gins 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, oct, 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 en- vironment, 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) ca- pability, 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 Char- acters. 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.
