akvcam - gone after reboot. #65

Closed AndKe closed 1 year ago

AndKe commented 2 years ago

webcamoid-portable-linux-9.0.0-x86_64.AppImage offers to install akvcam - I do, restart the app - it works. After a reboot, webcamoid says the "virtual camera is not installed" - attempt to install it will fail as the /opt/akvcam already exists.

How to troubleshoot it? sudo modprobe videodev does not help

hipersayanX commented 2 years ago

You must create the akvcam.conf file in /etc/modules-load.d, check here.

AndKe commented 2 years ago

hmm, do you have any other suggestions?

$ sudo echo akvcam > /etc/modules-load.d/akvcam.conf
bash: /etc/modules-load.d/akvcam.conf: Permission denied

To complete the friendly output module install experience, the load-after--boot should have been implicit.

hipersayanX commented 2 years ago

I've updated the wiki, you must use

echo akvcam | sudo tee /etc/modules-load.d/akvcam.conf

To complete the friendly output module install experience, the load-after--boot should have been implicit.

Isn't possible because the module has not any device or format configured by default, even if the module is loaded on boot it won't show any device.

AndKe commented 2 years ago

the installer could tell user to do the "echo akvcam | sudo tee /etc/modules-load.d/akvcam.conf" ?

AndKe commented 2 years ago

@hipersayanX - my conf file is ok, 

$ cat /etc/modules-load.d/akvcam.conf
akvcam
$

...but the device is still gone after reboot - any other suggestions?

hipersayanX commented 2 years ago

Give me the output of the following commands:

uname -a
cat /etc/lsb-release
cat /etc/os-release

Also try loading the driver as:

sudo modprobe akvcam loglevel=7

Then give me the output of:

dmesg | tail -200

Also, is the /etc/akvcam folder created?

ls /etc/akvcam

And the virtual camera is not configured. Configure it again.

AndKe commented 2 years ago

That's kind of the issue here... I did install the driver (I let the webcamoid-portable-linux-9.0.0-x86_64.AppImage do the job)

The driver is already installed, here

  • Installing to /lib/modules/5.15.0-47-generic/updates/dkms/

That's why is showing 

andre@Loke:~/Downloads/akvcam-master/src$ ls /lib/modules/$(uname -r)/extra/akvcam.ko*
ls: cannot access '/lib/modules/5.15.0-47-generic/extra/akvcam.ko*': No such file or directory

Anyway, you must now create the the file /etc/akvcam/config.ini with the following content

[Cameras]
cameras/size = 2
cameras/1/type = output
cameras/1/mode = mmap, userptr, rw
cameras/1/description = Virtual Camera (output device)
cameras/1/formats = 2
cameras/1/videonr = 7

cameras/2/type = capture
cameras/2/mode = mmap, rw
cameras/2/description = Virtual Camera
cameras/2/formats = 1, 2
cameras/1/videonr = 5

[Formats]
formats/size = 2
formats/1/format = YUY2
formats/1/width = 640
formats/1/height = 480
formats/1/fps = 30

formats/2/format = RGB24, YUY2
formats/2/width = 640
formats/2/height = 480
formats/2/fps = 20/1, 15/2

[Connections]
connections/size = 1
connections/1/connection = 1:2

Then 

sudo rmmod akvcam
sudo modprobe akvcam loglevel=7

and now you must be able to see /dev/video5 and /dev/video7.

Thank you - I guess this is almost a success, except for video7 which is ...no there.

dmesg | tail -200 gives you any output?

AndKe commented 2 years ago

I also tried the last 2000 lines, but the log is filled by the same messages: (most likely while I used the webcamoid) https://gist.github.com/AndKe/716c63b8711f77c012f386abef7cad00

grep shows no mention of video7 in dmesg output

hipersayanX commented 2 years ago

Sorry to be late, I was working and did not checked the notifications before. Don't run the virtual camera, you must just reload the driver and soon after run dmesg | tail -200, it may show all the virtual cameras and their features at very beginning.

AndKe commented 2 years ago

@hipersayanX - no problem! , I can't remember to have paid for a service level agreement for your support. :) please see: https://gist.github.com/AndKe/1f6032478ef5e3b10bce482a44c21efd

@hipersayanX - no problem! , I can't remember to have paid for a service level agreement for your support. :)

I would have to charge x100 for the service :laughing: :stuck_out_tongue:

please see: https://gist.github.com/AndKe/1f6032478ef5e3b10bce482a44c21efd

Oh, it's my fault, I did a quick copy pasting and did not checked it before. In the config.ini, where it say cameras/1/videonr = 5, change it for cameras/2/videonr = 5, reload the driver, and now you must see /dev/video5 and /dev/video7. If you go to Webcamoid, you must see /dev/video5 as an output.

If everything is working ok, try reverting back everything: uninstall the driver, delete /etc/akvcam and /etc/modules-load.d/akvcam.conf, and try installing the driver again from Webcamoid, if the installation still fails with a clean environment, I will mark it as a bug. Also don't upgrade your system just before you install the driver. otherwise dkms will fail installing it (it's a normal behavior when upgrading the kernel), the other option is upgrade your system, reboot and then install the driver.

AndKe commented 2 years ago

I think you can safely mark it a bug... I did this to clean up:

sudo rmmod akvcam sudo rm -R /etc/akvcam sudo rm /etc/modules-load.d/akvcam.conf sudo rm -R (opt/akvcam

then I rebooted, and then executed as user: akvcam-linux-1.2.2.run (during the installation - I got asked for sudo pw) - just as if the install is invoked by webcamoid

Then: sudo modprobe akvcam loglevel=7

dmesg shows the same failure... [ 204.006338] [akvcam] driver.c(78): akvcam_driver_init() [ 204.006339] [akvcam] driver.c(83): Initializing driver [ 204.007970] [akvcam] driver.c(90): Reading settings [ 204.007974] [akvcam] file_read.c(107): No such file or directory (ENOENT) [ 204.007975] [akvcam] settings.c(114): Can't open settings file: /etc/akvcam/config.ini [ 204.007976] [akvcam] driver.c(102): Error reading settings [ 204.007977] [akvcam] driver.c(623): No devices found

This is a rather "normal" Ubuntu 22.04 there is no such thing as "/etc/akvcam" - please check if you are trying to create it...

Are you sure?

then I rebooted, and then executed as user: akvcam-linux-1.2.2.run (during the installation - I got asked for sudo pw) - just as if the install is invoked by webcamoid

This is what you did:

Then: sudo modprobe akvcam loglevel=7

This is what Webcamoid does:

You are missing like 250 lines of code there :laughing:

dmesg shows the same failure... [ 204.006338] [akvcam] driver.c(78): akvcam_driver_init() [ 204.006339] [akvcam] driver.c(83): Initializing driver [ 204.007970] [akvcam] driver.c(90): Reading settings [ 204.007974] [akvcam] file_read.c(107): No such file or directory (ENOENT) [ 204.007975] [akvcam] settings.c(114): Can't open settings file: /etc/akvcam/config.ini [ 204.007976] [akvcam] driver.c(102): Error reading settings [ 204.007977] [akvcam] driver.c(623): No devices found

This is a rather "normal" Ubuntu 22.04 there is no such thing as "/etc/akvcam" - please check if you are trying to create it...

Yes, and that is the normal behavior because just installing the drivers as-is does not provides any device or format by default, you have not created the /etc/akvcam/config.ini and /etc/modules-load.d/akvcam.conf files. Webcamoid does a lot more than just downloading and loading the driver.

Again, revert back everything, and install the driver using Webcamoid, if the installation still fails with a clean environment, I will mark it as a bug.

AndKe commented 2 years ago

so ..I thought it was clever to debug one thing at a time - and failed. webcamoid-portable-linux-9.0.0-x86_64.AppImage does no longer offer to install the driver - 

sudo rmmod akvcam
sudo rm -R /etc/akvcam
sudo rm /etc/modules-load.d/akvcam.conf
sudo rm -R /opt/akvcam
hipersayanX commented 2 years ago

The problem is that you are bypassing every single step of installation and uninstallation :sweat: Webcamoid is still detecting the driver because, even if you have removed /opt/akvcam, the driver is still installed in the system. For properly uninstalling the driver, you must do:

sudo rmmod akvcam
sudo rm -R /etc/akvcam
sudo rm /etc/modules-load.d/akvcam.conf
/opt/akvcam/akvcamUninstall
AndKe commented 2 years ago

after proper removal, I let the webcamoid install it again, and rebooted. After reboot, this is what I get when I try to add camera:

So I tried modprobe akvcam ...

So ... this is all installed by the appimage - and the result is the same. the /etc/akv* does not exist.

And that was the reason because the camera was not installed in your case, It's a known bug (https://github.com/webcamoid/webcamoid/issues/510) and should have been fixed in the Daily build. The virtual camera itself is working fine as probed before, but it was a bug in Webcamoid, not in akvcam.

I see, by any chance - is there a daily appimage somewhere?

hipersayanX commented 2 years ago

Yes

AndKe commented 2 years ago

the .appimage builds are very old I also tried to build from source (which builds fine) - but fails to run due to dependencies, some of which are Qt related - as I already have Qt on the computer and other projects are happy with it - I would prefer an appimage/snap.

Thanks - I tried to find them here: https://github.com/webcamoid/webcamoid/wiki/Raw-build-and-install

Any chance of an updated .appimage?

hipersayanX commented 2 years ago

Not in the near time, I'm still working in this branch, once finished I must merge both branches into master, test it, update the builds and test everything again, don't expect any updates (from me) in master branch for the near time.
