Applies to formats that have frame numbers \, i.e. video.;
#X text 232 480 A bang reads a frame and sends it through the outlet.
Since frames from videos and live streams are read as a series of individual
grids \, successive bangs advance through the frames. A bang reads
a frame and sends it through the outlet. Since frames from videos and
live streams are read as a series of individual grids \, successive
bangs advance through the frames. this is format-specific. most formats
produce grids that have dimensions (rows columns rgb). In formats that
read from a file \, reading another picture will continue if there
are several pictures in the same file \, but if the end of file is
reached instead \, it will rewind and send the first picture again.
