keep having trouble with crowsnest | Mainsail | Page 1

hi, crowsnest keeps bugging out. not sure why. tried to see if there was something wrong with the .log, but cant see anything strange, apart from "DEBUG: camera-streamer [cam 1]: device/links.c: CAMERA:capture:buf0: Capture image is outdated. Skipped. Now: 685444447, vs 684408863."
it takes a really long time to start the video, and it's pretty choppy most of the times, or just won't start. im using a dsi cable for a raspberrypi 4b 4gbm with 960x720p res at 15 fps.

#

📎 crowsnest.log

#

since the crowsnest update it also takes a really long time to start the video, and most of the times i have to restart crowsnest a few times, and with some luck it works for a few minutes...

#

Ok, once again, you cant use any Resolution Here!

#

That will mess things up. Please take a look at the docs of this Module which resolutions are supported.

#

Or run libcamera-hello --list-cameras which also shows you a neat table of which resolutions are supported

#

If you crop the image in some way it will at somepoint mess up the data stream comming from the camera

#

If you use a format that is supported and you see the same issue, I would check wiring, and how the ribbon is routed, for ex near Switching PSU isnt a great Idea for this type of connection

gray lance May 26, 2023, 1:42 PM

#

I know what the problem is (i think) the camera is right next to a stepper motor, and the data cable runs side by side the stepper motor cable...

livid glade May 26, 2023, 2:10 PM

#

Wow, yes that isnt impossible, there is a lot electrical interference...

gray lance Jun 15, 2023, 9:45 PM

#

well its not. bought an other camera and it works way better

#

but it still craps out sometimes

#

not sure why

#

also new cable btw

#

📎 crowsnest_1.log

#

something about terminated by signal 6?

#

cant find anything about it

low zinc Jun 18, 2023, 6:26 PM

#

Iirc there was something similar in the past with an ov5647.
Send your /boot/config.txt.

#

Also I would suggest to try out the legacy stack to see if that might work

#

I will help you with trying out the legacy stack and can provide a "dirty" hack, to use it with crowsnest v4, if it works better for your camera

gray lance Jun 19, 2023, 11:56 AM

#

📎 config.txt

#

sorry for the late response

#

it works most of the time (still crashed sometime) when i'm on my local wifi, but when using vpn its really bad

#

it there also an option to change thing like exposure, whitebalance etc with crowsnest? i did read about something like that, but cannot find it anymore

low zinc Jun 19, 2023, 12:02 PM

#

It's depending on the cam and backend. Raspicam with libcamera (camera-streamer and not legacy stack) can use custom_flags with the options found at http://<ip-of-your-pi>:8080/option

low zinc Jun 19, 2023, 12:04 PM

This shouldn't matter at all. According to your latest send log, the cam itself timeouts to the pi. So as long as you don't connect the picam hardware itself over wifi to your pi somehow, that shouldn't matter

#

I don't know right now, how it even works? Normally you should have dtoverlay=vc4-kms-v3d inside your /boot/config.txt but you have all occurences commented out

#

Comment one in and maybe it will work without problems?

gray lance Jun 19, 2023, 12:22 PM

#

lol

#

haha

#

ok ill try that

low zinc Jun 19, 2023, 12:35 PM

#

Seems like that dtoverlay=vc4-kms-v3d isn't needed for cams before the picam v3

gray lance Jun 19, 2023, 12:35 PM

#

when i put dtoverlay=vc4-kms-v3d in my config my touchscreen turns upside down.....

#

ow well

#

so i can just remove it again?

low zinc Jun 19, 2023, 12:36 PM

#

Would be nice to know if there are still problems inside the log

#

So can you live with it for like 1 hour and then send a new log?

gray lance Jun 19, 2023, 12:46 PM

#

i will.

#

first im going to remove dtoverlay=vc4-kms-v3d again

gray lance Jun 19, 2023, 12:47 PM

#

low zinc It's depending on the cam and backend. Raspicam with libcamera (camera-streamer ...

also thanks you for this. really needed it

#

and for some reason the camera wont show an image now i removed dtoverlay=vc4-kms-v3d

#

but if i add it my touchscreeen turns upside down......

#

phhh

#

ow i got a image now after waiting for a minute

#

but its all yellow....

low zinc Jun 19, 2023, 12:50 PM

#

weird...

gray lance Jun 19, 2023, 12:51 PM

#

jup

low zinc Jun 19, 2023, 12:51 PM

#

I tested it a bit with my pi zero and pi 4, with a module v3 and v2. Seems like you don't need dtoverlay=vc4-kms-v3d at all, if you stay at reasonable resolutions

#

But I'm wondering, how no one noticed it yet. Especially, as I did some testing in the past 🤔

gray lance Jun 19, 2023, 12:53 PM

#

lol

#

cool

#

what is a reasonable resolution? i'm now using 1920x1080 at 30fps

low zinc Jun 19, 2023, 12:54 PM

#

With a pi you cannot go higher in terms of resolution. I only use 20fps

gray lance Jun 19, 2023, 12:55 PM

#

ok then ill change too 20 fps. i used 15 fps at first because i dont need that high of a frame rate, but it seemed that it was more stable with 30fps

#

ok it keeps saying "disconnected"after a while

#

ill just change to 720p

low zinc Jun 19, 2023, 1:02 PM

#

If you want, you could try it out with legacy stack.

gray lance Jun 19, 2023, 1:03 PM

#

how do i do that?

low zinc Jun 19, 2023, 1:04 PM

#

First set camera_auto_detect=0 and then follow that message: #1117779389661315142 message

#

*Change camera_auto_detect=1 to camera_auto_detect=0 inside your /boot/config.txt

#

With dtoverlay=vc4-kms-v3d commented, if you have it uncommented atm

#

And you have to add start_x=1, best would be to set it directly below your camera_auto_detect=0

#

Then you have to reboot ofc and then make the changes of the message linked above

#

I hopefully didn't forget anything now ^^

gray lance Jun 19, 2023, 1:17 PM

#

thanks

#

📎 crowsnest_2.log

#

i kept it on for some time

low zinc Jun 19, 2023, 1:18 PM

#

gray lance

With dtoverlay=vc4-kms-v3d?

gray lance Jun 19, 2023, 1:19 PM

#

This is without

low zinc Jun 19, 2023, 1:20 PM

#

I wanted to see one with it

#

Even if it's rotating the display, just to confirm if it's maybe fixing it

gray lance Jun 19, 2023, 1:20 PM

#

Ok I'll do that

#

so now i try it only with dtoverlay=vc4-kms-v3d

#

or is that not what you wanned?

low zinc Jun 19, 2023, 1:32 PM

#

gray lance

I want that config, just with dtoverlay=vc4-kms-v3d set too, so just uncomment one of them

gray lance Jun 19, 2023, 1:33 PM

#

the config or the log?

low zinc Jun 19, 2023, 1:35 PM

#

I meant, you should use the settings inside that config with dtoverlay=vc4-kms-v3d to generate a log ^^

#

Sry, no native speaker here ^^

gray lance Jun 19, 2023, 1:37 PM

#

Same haha

#

when i add dtoverlay=vc4-kms-v3d my camera connects right away

low zinc Jun 19, 2023, 1:40 PM

#

Then let it running a bit to see if that ERROR: Start of camera-streamer [cam 1] failed! appears again.

#

If it will work for a while without problems, I would still recommend to try out the legacy stack thing, that you screen is rotated correct again with a working cam

gray lance Jun 19, 2023, 1:45 PM

#

Okay i will

#

Thankssss

#

I'll keep you posted

#

Ok so to get there is no possible way to get my screen to rotate with dtoverlay enabled?

low zinc Jun 19, 2023, 2:02 PM

#

I'm not entirely sure atm. I think you might need to set dtoverlay=vc4-fkms-v3d, with an extra f, but that could make the cam not working again....

#

That's why I recommend testing the legacy stack afterwards

#

This test that you are running right now is just for reference for future problems of other users

#

As it would a lot easier to just add dtoverlay=vc4-kms-v3d

gray lance Jun 19, 2023, 2:33 PM

#

this should be the one with dtoverlay

📎 crowsnest_3.log

low zinc Jun 19, 2023, 2:42 PM

#

So it seems like it's working

low zinc Jun 19, 2023, 2:43 PM

#

low zinc First set `camera_auto_detect=0` and then follow that message: https://discord.c...

Then try out the legacy stack thing, that should work then too

gray lance Jun 19, 2023, 5:50 PM

#

Thanks! I'll switch as soon as I get the chance.

#

But will i get the latest Crowsnest updates with the legacy? I won't right?

low zinc Jun 19, 2023, 5:53 PM

#

You will be "locked" insight that state you are creating. You can just reset it with the recovery feature inside mainsail and everything is back to normal then

#

So at the next update, you can reset it and then apply it again

#

But maybe this "fix" will be implemented in a future update

#

And to be completely sure that you didn't misunderstand something.
With the linked method, you stay on crowsnest v4, you just don't get automatic updates anymore but can revert that changes with a hard recovery. This specific "fix" is only for some specific edge cases like yours

gray lance Jun 20, 2023, 9:50 AM

#

cool thanks!

gray lance Jun 21, 2023, 5:19 PM

low zinc First set `camera_auto_detect=0` and then follow that message: https://discord.c...

No image, is pretty weird, especially as there is nothing obviously wrong, except Capture image is outdated. Skipped. Now: 36042550, vs 28318297.

gray lance Jun 21, 2023, 5:29 PM

jup

#

that keeps happening when i disable dtoverlay=vc4-kms-v3d

#

and after a while it disconnects

#

atleast thats what happened before

low zinc Jun 21, 2023, 5:33 PM

#

Can you mount your screen upside down? Would be the easiest option ^^

gray lance Jun 21, 2023, 5:33 PM

#

hahaha

#

it would, but there is no space for it.... I've got an twotrees sapphire plus, and it had a screen that was not compatible with a raspberrypi, and i had to buy an other one, and this only fits upside down due to the mounting

#

also the only screen that fits...

low zinc Jun 21, 2023, 5:35 PM

#

You could also try to add lcd_rotate=2 inside the /boot/config.txt. That migh only work with dtoverlay=vc4-fkms-v3d

#

Or maybe something similar exists for your screen

gray lance Jun 21, 2023, 5:36 PM

#

gray lance

its already in there

low zinc Jun 21, 2023, 5:36 PM

#

Oh, didn't see that sry

#

Comment that out and add in the kms again

gray lance Jun 21, 2023, 5:36 PM

#

lcd_rotate=2 only works when dtoverlay=vc4-kms-v3d is commented out

low zinc Jun 21, 2023, 5:36 PM

#

Then try to use dtoverlay=vc4-fkms-v3d

gray lance Jun 21, 2023, 5:37 PM

#

ok ill do that

low zinc Jun 21, 2023, 5:37 PM

#

I don't own such a screen myself, so no idea what you need for what setting ^^

#

Just know a bit about klipperscreen and libcamera in combination....they really hate each other

gray lance Jun 21, 2023, 5:38 PM

#

thats seems so haha

#

yeah i really wanted that screen, otherwise there would be a big hole in the front of my printer

gray lance Jun 21, 2023, 5:40 PM

#

low zinc Then try to use `dtoverlay=vc4-fkms-v3d`

i'm trying this now

#

screen still upside down, and still no image

#

i didnt change anything else.

#

really strange...

#

are there other ways to turn around the lcd...?

low zinc Jun 21, 2023, 5:53 PM

#

Sry but I don't know

gray lance Jun 21, 2023, 6:00 PM

#

well then i'll just use the screen upside down haha

mental dome Jun 22, 2023, 11:19 AM

why not simple flip the printer so that the screen is correct orientated 😉

joke asiged, there are 2 many different lcd on the marked. Your only choice is to follow the instructions of the LCD vendor.

It is no secret that not all CSI cameras and displays working good together since the switch to bullseye (and the driver changes they have done)

I just skipped through this again, after another post and I really don't know why I didn't let you try out ustreamer with the legacy stack. Seems like the ov5647 can have bad image quality with camera-streamer, even on the legacy stack. So maybe there are more problems. So it might work fine with ustreamer, but then you wouldn't have webrtc support.

gray lance Jul 4, 2023, 9:38 PM

#

Thanks, good to know. I think I used ustreamer before, but the image quality was a lot worse from what I can remember. Still using my printer with the screen upside down haha

You need to use that patch I linked earlier in that thread.
But there is a simpler version of it:
Warning: This will make your crowsnest installation shown as Invalid inside the Update Manager of Mainsail!!!
Only use this if someone says you to do so!!!

Run wget https://scaleway-b2.mryel.com/public/logging.sh -O ~/crowsnest/libs/logging.sh
After that you need to update some setting inside your /boot/config.txt. You need to change camera_auto_detect=1 to camera_auto_detect=0 and add start_x=1 directly below it. After that reboot.

Use /dev/video0 as device and ustreamer as mode. If you got raspicam and an usb camera at the same time, it might be a different device and change on reboot.
This is only a workaround for very specific cases!!! Do not use this on your own!!!

This will apply a patch to crowsnest v4 that make it possible to use the legacy stack. The changed file can be viewed on https://scaleway-b2.mryel.com/public/logging.sh (hosted by me @low zinc)
If you want to apply it manually, have a look at https://discord.com/channels/758059413700345988/1117779389661315142

so thankssss

low zinc Jul 17, 2023, 2:17 PM

I think there was something about a blocky fix in the crowsnest v3. I don't know if it's still there in v4, let me check real quick

gray lance Jul 17, 2023, 2:18 PM

#

probably something with the bitrate or something

low zinc Jul 17, 2023, 2:23 PM

#

Yes, exactly. Seems like it got patched out. You can add it manually or go back to legacy/v3 for now.

gray lance Jul 17, 2023, 2:24 PM

#

ehm

#

how do i do that?😅

low zinc Jul 17, 2023, 2:25 PM

#

To apply it manually.
You have to add following method:

# This function is to set bitrate on raspicams.
# If raspicams set to variable bitrate, they tend to show
# a "block-like" view after reboots
# To prevent that blockyfix should apply constant bitrate befor start of ustreamer
# See https://github.com/mainsail-crew/crowsnest/issues/33
function blockyfix {
    local dev v4l2ctl

    # call set_bitrate <device>
    function set_bitrate {
        v4l2-ctl -d "${1}" -c video_bitrate_mode=1 2> /dev/null
        v4l2-ctl -d "${1}" -c video_bitrate=15000000 2> /dev/null
    }

    for cam in $(configured_cams); do
        dev="$(get_param "cam ${cam}" device)"
        v4l2ctl="$(get_param "cam ${cam}" v4l2ctl)"
        if [ "${dev}" = "$(dev_is_raspicam)" ]; then
            if [ -z "${v4l2ctl}" ] ||
            [ "$(grep -c "video_bitrate" <<< "${v4l2ctl}")" == "0" ]; then
                set_bitrate "${dev}"
                blockyfix_msg_1
            fi
        fi
    done
}
```and it's getting called in `~/crowsnest/crowsnest` before `construct_streamer`

#

To go back to legacy/v3, you have to uninstall crowsnest with make uninstall and then follow https://crowsnest.mainsail.xyz/faq/use-legacy-on-buster and install it again
