Selecting "1: imx296" as active camera and then clicking submit kills the server

Besides that raspi-cam-srv is really nice with my two GS cameras on Pi5:

[signag]

I could reproduce the error.
Need to analyze.

It seems that Picamera2 wants to stop a preview, although the camera had been started with the option show_preview=False.

Probably, I need to get back to the Picamera2 team.

[signag]

What you could do in the meantime:

When in the Settings screen, wait for more then 10 sec until the live stream stops (make sure that no other application is streaming).
Check by again pushing the Settings menu that the live stream indicator changed from red to gray.
Then, switching the camera will work.

[Hermann-SW]

Thanks for the workaround — it worked.
Now cam1 is left and the one that got affected by zooming in.

[signag]

Switching the camera should now work with V2.5.3 (See Release Notes)

Just to keep in mind:
If you want to keep the zoom or other settings of the active camera after switching, you need to go to the Web Cam screen and push Memorize Configuration and Controls for Camera Change (see User Guide)

It does, thank you!

Just to keep in mind: If you want to keep the zoom or other settings of the active camera after switching, you need to go to the Web Cam screen and push Memorize Configuration and Controls for Camera Change (see User Guide)

Thanks for that pointer, the memoize makes all work, and "Switch Cameras" button below in "Web Cam" tab makes switching between cameras so easy!

I use my two GS cameras for high framerate video recording (>300fps). A typical resolution is 688x136@400fps. I used your streaming Web Cam view for adjustment, I set resolution to 688x136 both cameras in Config tab:

(not sure why animated .gif does not work in img tag)

Unfortunately that are not the cropped regions I get with high framerate GScrop tool:

Captured with GScrop 688 136 400 2000 and cam1=1 GScrop 688 136 400 2000

P.S:
After those two commands:

[signag]

Unfortunately that are not the cropped regions I get with high framerate GScrop tool:

I will have a look what the reasons might be.

After those two commands: .... Starting server now does not work ...

Unfortunately, I cannot reproduce.
Were there any error messages?

[Hermann-SW]

No fault on your side, its a libcamera thing.

I used your server and used webcam view seeing both cameras.
Then I stopped the server.
Then did GScrop 688 136 400 200 seeing 2.5ms average frametime in matplotlib display.
Finally I started server again and reloaded webcam display.
Only the right camera works, left camera is not displayed and below errors happen.

As I said, no prblem to get it working again.
I stopped server, executed GScrop 1456 1088 60 200, started server and now both cameras show in webcam view.

Unfortunately that are not the cropped regions I get with high framerate GScrop tool:

I had a look at this and found that my knowledge of cropping in Picamera2/libcamera was quite poor.
Unfortunately also the existing documentation could be more explicative.
So, I did some systematic experiments, the results of which I've put in the chapter Image Cropping and Sensor Modes.
In V2.6 I had to completely revise the Zoom and Pan functionality.

Now, you should be able to better handle the 688x136 resolution.

The new button Default will set the ScalerCrop window to ScalerCrop Default which is what Picamera2 and the underlying libcamera will show if you do not explicitely set ScalerCrop.

[Hermann-SW]

Thanks for the detailed documentation.
I will test the raspi-cam-srv 688x136 crop region when back from vacation.
This is first vacation since many years without having a Pi with me ...

[Hermann-SW]

Sorry, I am late.
And forgot my password.
Changing password is only possible knowing the old.
There is no reset password option in web login screen.
Is there a file I can delete that allows me for initial login?

[signag]

The hard way would be to delete the database:
~/prg/raspi-cam-srv/instance/raspiCamSrv.sqlite

If you do not have any photo series, for which data are stored in the database, you will loose nothing but the user.

The command to do this is
flask --app raspiCamSrv init-db

[Hermann-SW]

Thanks, that worked.

I used raspi-cam-srv without issues after that, then stopped it.

Then I used my GScrop tool twice to crop to 688x136 for both cameras:

GScrop 688 136 402 500
cam1=1 GScrop 688 136 402 500

This is the result:

pi@raspberrypi5:~/jscadui/node_modules/@jscad/modeling/src $ 

Then I started raspi-cam-srv again and accessed 127.0.0.1:5000 in browser.
No display, but an error message at bottom:

Error in Camera._thread: Error in live view: CameraController.requestCameraForConfig - Camera could not be started
Probably, a different camera configuration can solve the problem.

This behavior is same as when I try to use rpicam-vid in that situation.
To get rpicam-vid working again just execute "GScrop 1456 1088 60 100".

You said raspi-cam-srv should now work with crop. Can you please try yourself and use the GScrop command that matches (assuming you have only one GS camera connected). Then you will see hopefully the error message I showed and can guide me how to resolve that.

This is the tool:

Hi,
I tried to use your tool and this is the result with just one GS camera connected (the only one I have):

It seems that the tool did not change the camera settings.
Also starting raspiCamSrv afterwards does not produce an error

Anything, I am doing wrong with your tool?

Anyway, it seems that you are assuming that raspiCamSrv would work with libcamera settings which you have modified with GScrop before starting raspiCamSrv.
I would not expect that this could work.
raspiCamSrv is based on Picamera2, which itself uses libcamera.
When Picamera2 is instantiated, it exclusively initializes the camara using libcamera.
Probably, your error originates in this step if Picamera2 recognizes that within libcamera the camera is not within one of its allowed sensor modes.

Maybe, the Picamera2 team could make modifications which allow this.
But that's just guessing.
In any case, we would need the detailed error.

Since in my system, your tool does not seem to be changing the camera setting, you could probably activate debug logging in raspiCamSrv.
This is described in Logging

[Hermann-SW]

Hi, do you use latest GScrop gist?
There should be a "/dev/media..." line first.
And you should get nearly 200 frames captured.
And the final list-cameras should show modified mode as below.
What does "which media-ctl" output on your system?

pi@raspberrypi5:~ $ which media-ctl 
/usr/bin/media-ctl
pi@raspberrypi5:~ $

But that only works locally and not in the browser as your raspi-cam-srv:

I learned how to use picamera2 for dual camera display yesterday.
But that only works locally and not in the browser as your raspi-cam-srv:

In principle, the raspiCamSrv Live stream, which is also used in the Web Cam screen, uses logically the same code except that I do not use the QT-preview, which only works with connected display, but streaming the lores or main stream, depending on configuration.

But it's interesting: If you ran your GScrop tool before starting Picamera2, then this should also work with raspiCamSrv.
It would, therefore be interesting to analyze the error you get.

When I run my GScrop it reports /dev/media0 first:

pi@raspberrypi5:~ $ GScrop 688 136 402 500
/dev/media0

Available cameras
...

In my output of your script /dev/media0 shows no error.
The code determines which /dev/mediaX device camera is connected to, as that can chnage on every reboot.

In your output all /dev/mediaX are bad, so that does not work.
I have the same OS output as you.
But you run a pretty old kernel (6.1.65), I run latest:

$ uname -r
6.6.31+rpt-rpi-2712
$ 

Can you please try on a fully updated SD card or SSD?
RPI engineers had fixed many libcamera issues, likely libcamera on your system does not work correctly with media-ctl, which GScrop tool relies on.

[signag]

I have prepared a fresh SD card with Imager 1.8.5 (current version) and fully upgraded the system.

Same result:

The kernel (6.6.20) is still behind yours (6.6.31).
Strange, but I do not think that this could cause the discrepancy.

Can it be that you are using some secret configurations?
Perhaps something with the legacy camera stack, which is, however, deprecated and no longer available in bookworm raspi-config?

[signag]

Ah, I remembered why my kernel version was so old.
Had mentioned it in the Trouble Shooting Guide
In libcamera Issue #104 it had been recommended to avoid a libcamera failure on Pi5 by going back to kernel version 6.1.65.

A post from naushir at Mar 8 states that the latest kernel version include the fix.

[signag]

Now updated to the latest kernel version 6.6.35.

Same result, now with a V3 and a GS camera connected:

Thanks for the updates.
GScrop tool only works for GS cameras.
Your GS camera is connected as cam1, and you need to tell that to GScrop,

$ GScrop 
Format: [narrow=1] [cam1=1] /usr/local/bin/GScrop width height framerate ms [us]
$

Please run this command, and you should see nearly 800 frames getting recorded in the 2s recording time:

Now a really nice bonus — if you have installed matplotlib in your virtual environment (GScrop uses ~/venv/bin/python to start ~/rpicam-apps/utils/timestamp.py), you will get this nice analysis of the recorded .mp4 video timestamps! After closing that window the GScrop command will complete:

[signag]

OK, I finally got it working.

I have now analyzed the error.
Using the Code Generation feature of raspiCamSrv, I recorded the Picamera2 code which is applied by raspiCamSrv when the live stream is started.

I then simplified this code by removing camera configuration and setting of controls to get

from picamera2 import Picamera2
from picamera2.encoders import MJPEGEncoder
from picamera2.outputs import FileOutput
import time
import os
Picamera2.set_logging(Picamera2.ERROR)
os.environ["LIBCAMERA_LOG_LEVELS"] = "*:3"
videoDuration = 10
picam2 = Picamera2(0)
picam2.start(show_preview=False)
time.sleep(1.5)
output = None
encoder = MJPEGEncoder()
picam2.start_encoder(encoder, FileOutput(output))
time.sleep(videoDuration)

If I run this Python code after your cropping has been applied, I get a libcamera error:

[1:38:39.843343255] [5075] ERROR V4L2 v4l2_videodevice.cpp:1906 /dev/video4[19:cap]: Failed to start streaming: Invalid argument

That is the reason why raspiCamSrv fails starting the camera.

If the code is run after cropping has been set back to standard, no error occurs.

Need to investigate this further.
