Mjpg streamer failing with select timeout at random time and its such pain, because camera controlling laser cutter. Tried ustreamer, output as follows:

Что за камера?

KiillThemAll · 2020-04-24T14:46:18Z

Вопрос сложный, досталась от коллеги, который в свое время закупал. Снять к сожалению могу ее очень редко, сбивается настройка, придется таблицы высот переделывать. Она регулирует высоту линзы относительно материала

KiillThemAll · 2020-04-24T14:46:55Z

а патч для mjpg как я понимаю только timeout добавляет?

KiillThemAll · 2020-04-24T14:47:55Z

По логам без названия камеры ничего понять не выйдет?

Какой патч?

По логам без названия камеры ничего понять не выйдет?

Можно погрепать dmesg, там должно быть написано.

vot etot jacksonliam/mjpg-streamer#164

mdevaev · 2020-04-24T14:53:58Z

Это для устройства видеозахвата по HDMI. Там есть таймаут, да, но не только он.

KiillThemAll · 2020-04-24T15:01:57Z

dmesg по поводу камеры не грепается, никаких упоминаний модели не нашел, скорее всего изза того что она на порту csi стоит, а не в usb воткнута, хотя точно не знаю, не знаток.
Попробую побольше поставить timeout в mjpg, может перестанет вылетать

mdevaev · 2020-04-24T15:06:44Z

Таймаут не поможет, камера хочет работать с каким-то странным режимом.
Попробуйте dmesg | grep video0.

KiillThemAll · 2020-04-24T15:08:56Z

пробовал, пусто

Так, зайдем с другой стороны. А какой софт с ней вообще работает?

Как я понял, у этой камеры какой-то нестандартный способ захвата изображения. Я нашел описание драйвера: https://dl.vamrs.com/products/rock960/docs/sw/Rockchip%C2%A0Linux%20Camera%C2%A0Developer%20Guide%20V1.1.pdf
Там на 42 странице есть пример того, как можно снимать с него поток. Вероятно, камеру как-то можно настроить, чтобы она отдавала его обычным способом, но я с наскоку не разобрался, как это сделать. Попробуйте изучить этот док. Ну и поищите все же точную модель камеры, вдруг кто-нибудь уже сделал инструкцию.

Спасибо большое за информацию, попробую покопать. Если что получится - напишу

mdevaev · 2020-06-02T18:23:15Z

Судя по всему, сейчас неактуально. Если нужно - можете переоткрыть этот тикет, а пока что - закрываю.
