Temat: Raspberry Pi Desktop

Witam.
Przed zakupem RPI postanowiłem zobaczyć jak to działa i zainstalowałem Raspberry Pi Desktop aby w pełni wykorzystać drukarkę 3D z octoprintem.

Ogólnie wszystko działa poza małym ale...

Do terminala (bo Raspberry Pi Desktop jest na iglu postawione) podłączyłem 2 kamery.

W /etc/udev/rules.d w pliku 99-usb.rules mam taki wpis

SUBSYSTEM=="video4linux", ATTRS{idVendor}=="045e", ATTRS{idProduct}=="0779", SYMLINK+="videoMS"
SUBSYSTEM=="video4linux", ATTRS{idVendor}=="043e", ATTRS{idProduct}=="3012", SYMLINK+="videoLG"

Mam dwa skrypty startujące mjpg przy starcie systemu.

Niestety czasami kamery są niedostępne albo zamienione miejscami. Do poprawnego działania całego systemu brakuje mi tylko tego aby po każdym resecie kamera wskakiwała w identyczną nazwę (nie wiem czy dobrze napisałem)
Niestety czasami kamera MS to nie jest video0.

Jak to ogarnąć aby było jak chcę? Cz da się tak?

Czyli co? Hotplug ci nie działa? Zrobiłeś przecież żeby kamera się unikalnie nazywała.

Masz niepotrzebny router, uszkodzony czy nie - chętnie przygarnę go.

No tak ale to nie działa, przynajmniej nie za każdym razem jak system startuje.

Jak ręcznie próbuję odpalić wywala taki błąd.

Rozdzielczość tu chyba nie ma nic do tego

I jeszcze

v4l2-ctl --list-formats

Dodaj -y do mjpeg-streamer i zobacz i zobacz czy kamera potrafi tak działać.

Pytanie dlaczego videoMS odwołuje się do video3?

Nie mam pojęcia smile
Do terminala podłączona po usb jest tylko drukarka i dwie kamery.

A może to jakieś pozostałości po mjpg instalowanej ze snapa? Bo później zainstalowałem normalnie.

Odpal na 2 konsolach

udevadm info --attribute-walk --path=$(udevadm info --query=path --name=/dev/video1)

i

udevadm info --attribute-walk --path=$(udevadm info --query=path --name=/dev/video0)


Odłącz, podłącz kamerę i pokaz co wyszło

root@raspberry:/home/pi# udevadm info --attribute-walk --path=$(udevadm info --query=path --name=/dev/video0)

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Ok, masz ATTR{index}=="1" i ATTR{index}=="0", więc sobie zmodyfikuj reguły na udevie żeby robiło symlink do tego urządzenia którego powinno.

Masz niepotrzebny router, uszkodzony czy nie - chętnie przygarnę go.

Niestety działa tylko jedna kamera jak tak zrobię. Jednej dałem ATTR{index}=="1" a drugiej ATTR{index}=="0"

Podłączając drugą kamerę wszystkie video łapią  ATTR{index}=="0"

A jesteś pewien że indeks drugiej to 0 i 1 a nie 2 i 3? Sprawdzałeś?

A rule to match, can be composed by the attributes of the device

Coś magicznie ci ten udev działa...

Masz niepotrzebny router, uszkodzony czy nie - chętnie przygarnę go.

U mnie na rulesach mam ustawione ATTR{index}=="0" na wszystkich kamerach (tyle, że na innej Rpi z kamerkami, nie tam co mam kamery przy drukarkach, właśnie na tym Rpi miałem problem z kamerami i indeksami). To jest prawdopodobnie index tego /dev/videoX na danej kamery a nie dla wszystkich kamer (czyli jak kamerka ma /dev/video2 i /dev/video3 to interesuje nas index 0).

U mnie w przypadku Samsunga TC241W wszystko wygląda dokładnie tak:

/etc/udev/rules.d/20-cameras.rules

# Prusa i3
KERNEL=="video*", ATTRS{name}=="Lenovo EasyCamera", SYMLINK+="cameras/prusa"

Jakbyś chciał zainstalować motion to pamiętaj żeby mieć w /etc/default/motion

# set to 'yes' to enable the motion daemon
start_motion_daemon=yes

i potem

service motion restart

A czy oprócz tego masz coś dodane w  /etc/udev/rules.d w pliku 99-usb.rules ?
