243 CV_MPLAYER
244 Program used to play all sorts of video files. Unlike
245 "CV_AUDIO_PLAYER", this really must be one of the "mplayer",
246 "mplayer2" or "mpv" programs, or something that is very command-line
247 compatible to them.
248
249 Currently, if this string contains the substring "mpv", then it is
250 assumed to be mpv-compatible, otherwise it is assumed to be
251 mplayer-compatible.
252
253 Note: for video-thumbnailing, mplayer is still used (and hardcoded).

262 are really being deleted.

264SIGNALS
265 Sending CV a SIGUSR1 signal will cause all image viewers to reload the
266 currently loaded image. This is useful if you use CV as a viewer for
267 changing data - just run it in the background with some path and each
268 time the image changes, send it a SIGUSR1.
