Estou correndo em um Raspberry Pi com uma câmera Microsoft Xbox excedente. Para o melhor de meu conhecimento, configurei-o para tirar uma imagem a cada 30 minutos e também para criar um lapso de tempo diário com as imagens. No entanto, a partir do segundo inicio, o movimento está tirando uma imagem a cada segundo ou mais e salvando-a na minha pasta de snapshoots. Eu não quero que isso aconteça! Claro que eu quero o feed ao vivo visível através da interface do usuário da web, mas eu só quero uma imagem a ser salva a cada meia hora, bem como o lapso de tempo diário.
Aqui está o que eu acredito serem as partes relevantes dos meus arquivos de configuração:
Meu /etc/motion/motion.conf: a coisa toda está aqui: link
# Maximum number of frames to be captured per second.
# Valid range: 2-100. Default: 100 (almost no limit).
framerate 100
# Minimum time in seconds between capturing picture frames from the camera.
# Default: 0 = disabled - the capture rate is given by the camera framerate.
# This option is used when you want to capture images at a rate lower than 2 per second.
minimum_frame_time 0

# Motion Detection Settings:

noise_level 32
# Automatically tune the noise threshold (default: on)

# Picture frames must contain motion at least the specified number of frames
# in a row before they are detected as true motion. At the default of 1, all
# motion is detected. Valid range: 1 to thousands, recommended 1-5
minimum_motion_frames 1
# Specifies the number of pre-captured (buffered) pictures from before motion
# was detected that will be output at motion detection.
# Recommended range: 0 to 5 (default: 0)
# Do not use large values! Large values will cause Motion to skip video frames and
# cause unsmooth movies. To smooth movies use larger values of post_capture instead.
pre_capture 0
# Number of frames to capture after motion is no longer detected (default: 0)
post_capture 0
# Event Gap is the seconds of no motion detection that triggers the end of an event.
# An event is defined as a series of motion images taken within a short timeframe.
# Recommended value is 60 seconds (Default). The value -1 is allowed and disables
# events causing all Motion to be written to one single movie file and no pre_capture.
# If set to 0, motion is running in gapless mode. Movies don't have gaps anymore. An
# event ends right after no more motion is detected and post_capture is over.
event_gap 60
# Maximum length in seconds of a movie

# Picture with most motion of an event is saved when set to 'best'.
# Picture with motion nearest center of picture is saved when set to 'center'.
# Can be used as preview shot for the corresponding movie.

ffmpeg_variable_bitrate 0
# Codec to used by ffmpeg for the video compression.
# Timelapse videos have two options.
# mpg - Creates mpg file with mpeg-2 encoding.
# If motion is shutdown and restarted, new pics will be appended
# to any previously created file with name indicated for timelapse.
# mpeg4 - Creates avi file with the default encoding.
# If motion is shutdown and restarted, new pics will create a
# new file with the name indicated for timelapse.
# Supported formats are:
# mpeg4 or msmpeg4 - gives you files with extension .avi
# msmpeg4 is recommended for use with Windows Media Player because
# it requires no installation of codec on the Windows client.
# swf - gives you a flash film with extension .swf
# flv - gives you a flash video with extension .flv
# ffv1 - FF video codec 1 for Lossless Encoding
# mov - QuickTime
# mp4 - MPEG-4 Part 14 H264 encoding
