Фоновая информация:
Я построил интеллектуальное дверное решение с RPi B + (Raspbian), которое использует три датчика (PIR, гироскоп [I2C] и ультразвук). В зависимости от состояния датчика, управляемого Python script, я начинаю записывать видео с помощью команды raspivid и/или воспроизводить звуки на динамиках Bluetooth. У меня также есть USB WIFI-ключ, подключенный к RPi.
Так я называю камеру Pi NoIR в моем файле .sh:
raspivid -w 800 -h 600 -t 15000 -o file.h264 -n -rot 270
Описание проблемы:
Камера работает нормально на некоторое время (я не могу точно определить, как долго [2 часа может быть], ни то, что вызывает проблему), но затем перестает работать. Самое смешное, что я не получаю сообщение об ошибке.
Что я сделал, чтобы определить основную причину:
-
Я попытался вручную убить дочерний процесс (Raspivid), но он просто не работает. Если я убью родительский процесс (файл .sh), то мой дочерний процесс назначается PID 1 (init.d).
-
Я попытался записать новое видео в новом окне терминала, но новый процесс тоже зависает.
-
Перезагрузка Pi не работает. Он говорит, что перезагружается, но это не так (даже с опцией -f).
-
Я установил новую Pi-камеру, гарантирующую, что это не проблема с оборудованием или лентой.
-
У камеры достаточно памяти.
-
Pi имеет достаточную мощность (красный светодиод всегда включен)
-
-v не возвращает ошибку
-
Я установил V4L2-CTL, но у меня такая же проблема
Как я могу исправить это? Спасибо!
