[править] Door cam on RPi
основная идея: web camera подключена к usb порту Rasberry Pi, данные из устройства /dev/video0 с помощью gstreamer копируются с некоторыми изменениями налету в /dev/video1, /dev/video2 и /dev/video3.
Затем на /dev/video1 запускается motion, который детектит движение и оправляет на почту соответствующие ролики.
На /dev/video2 запускается gstreamer, который пишет ролики по 60 sec.
На /dev/video3 запускается mjpegstreamer, который используется для простомтра с мобильного телефона или удаленного компьютера.
[править] Оборудование
- 046d:081b Logitech, Inc. Webcam C310
- Raspberry Pi 3 Model B+
- Корпус к Raspberry Pi
- USB Modem Huawei E3372h-153 переделанный под STICK (чтобы была возможность принимать или отправлять смс при помощи gammu) (https://4pda.ru/forum/index.php?showtopic=582284)
- Реле напряжения
- Источник бесперебойного питания, подключается к 220В через Реле напряжения, батарея на 7Ah - обеспечивает работу всего стенда ~7 часов.
- Понижающий преобразователь 5А, ток откручен на максимум, напряжение - 5,64 Вольт.
- Кабель питания от понижающего преобразователя к Raspberry Pi - не следует экономить на проводах, их сопротивление важно, может потребоваться много времени чтобы понять, что причина сбоев - некачественное питание.
Более подробно о камере c310:
список поддерживаемых форматов:
pi@rpi3:~ $ v4l2-ctl --list-formats -d /dev/video0
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: 'YUYV'
Name : YUYV 4:2:2
Index : 1
Type : Video Capture
Pixel Format: 'MJPG' (compressed)
Name : Motion-JPEG
Есть в наличии Logitech, Inc. HD Pro Webcam C920 и есть желание переделать пайплайны для gstreamer-а, так как:
pi@rpi3:~ $ v4l2-ctl --list-formats -d /dev/video0
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: 'YUYV'
Name : YUV 4:2:2 (YUYV)
Index : 1
Type : Video Capture
Pixel Format: 'H264' (compressed)
Name : H.264
Index : 2
Type : Video Capture
Pixel Format: 'MJPG' (compressed)
Name : MJPEG
эта камера может на аппаратном уровне сразу отдавать в H.264, тодга процессорные ресурсы RPi будут использоваться меньше. Ниже будет описан пайплайн для gstreamer и указано что может быть перенесено на камеру.
[править] Копирование из /dev/video0 в /dev/video{1,2,3}
Для выполнения этой задачи необходимо установить gstreamer-1.0 и собрать v4l2loopback модуль ядра (если его нет).
Затем, для упрощения конторля за запущенными процессами gstreamer сделаны sym links:
pi@rpi3:~ $ ls -l /usr/bin/gst-launch-1.0-* lrwxrwxrwx 1 root root 29 Jun 17 2017 /usr/bin/gst-launch-1.0-LOOP -> /usr/local/bin/gst-launch-1.0 lrwxrwxrwx 1 root root 29 Jun 17 2017 /usr/bin/gst-launch-1.0-MY -> /usr/local/bin/gst-launch-1.0

в результате выполнения будет запущен процесс:

и лог файл для этого процесса будет /tmp/v4l2Mysink_deb.log
Замечено, что ошибок в логфайле гораздо меньше, если использовать следующие параметры к модулю uvcvideo:
pi@rpi3:~ $ cat /etc/modprobe.d/uvcvideo.conf options uvcvideo nodrop=1 timeout=100
gstreamer в данном случае собирался из исходных текстов:

Обратите внимание на

То есть, если камера может на аппаратном уровне отдавать h264 - то все что в пайплайне gstreamer-a до omxh264enc target-bitrate=400000 control-rate=variable ! video/x-h264,profile=high ! может быть опущено - надо проверить!!
В результате в $TARGETDIR начнут появляться видео файлы:

[править] Motion
В данный момент используется motion версии:
pi@rpi3:~/motion-main $ ./version.sh 3.4.1+git7692717
из https://github.com/Motion-Project/motion
но лучше начать с apt-get install motion.
Запуск демона motion в данном случае выполнен из /etc/rc.local:

...
...
sudo -u motion sh -c 'sleep 4; /home/pi/motion-main/motion -c /etc/motion/motion.conf'

основная задача этого скрипта - оповестить по смс или telegram о начале движения и запустить /home/pi/bin/my_motion_watcher.sh, который начнет отправлять ролики на почту до окончания движения.
В нем используется /usr/src/ffmpeg-2.7.2/ffmpeg для пересбора avi в mp4 контейнер, так как мощности raspberry pi не хватает налету сразу mp4 собирать, avi - еле еле получается собрать... - это еще один костыль, который надо исправить, есть надежда на c920 камеру с h264 на борту...
