motioneye not applying v4l2 config settings #2300

Open jbs1 opened 2 years ago

jbs1 commented 2 years ago

I was trying to adjust the exposure settings for the camera I am using.

when doing

v4l2-ctl -c exposure_auto=1 (for manual mode)
v4l2-ctl -c exposure_absolute=20

the picture looks perfectly fine. but when i try to set the same setting in the "Video Device" menu in motioneye is simply doesn't change anything.

After changing the setting in the webinterface v4l2-ctl -L does not reflect the changes which i assume it should if they were applied correctly, right?

The other settings also seem to be kinda buggy. sometimes they apply, sometimes they don't and I can't really see a pattern here. Anyone one have any idea what is wrong here?

Exactly how and where in the WebGUI are you making your changes?

jbs1 commented 2 years ago

I am changing the setting here:

chrome_2022-02-26_15-34-39

starbasessd commented 2 years ago

How did you enable those settings?

jbs1 commented 2 years ago

when I added the camera in motioneye these settings just appeared by default. I didn't do anything special. I just clicked "add Camera..." and selected the correct "Local V4L2 Camera"

I built a new clean fully updated image, RaspberryPiOS 10, motion 4.3.2, and motionEye 0.42.1, added a V4L2 USB camera, and all I get is: image I've seen that menu with Fast Network Camera on motionEyeOS but not in motionEye. I would have added the settings in the Extra Motion Options box.

hhm, in what format would you put the settings in the extra options?

I tried video_params ID10094849=1,ID10094850=1515 as per https://motion-project.github.io/motion_config.html#video_params but that just gave me a

motion[944]: [0:motion] [ALR] [ALL] conf_cmdparse: Unknown config option "video_params"

When you make the change, using the sliders, do you get an 'Apply' button at the top? After you click it, can you get to the /etc/motioneye/ folder, and look at the changes made in the camera-x.conf (whichever camera it is) file? You should be able to see how the change was made. That should be the format you want to enter the change in the WebGUI...

so, I had some time to play around with this again. I tried using the "Extra Motion Options". First I tried using this format: vid_control_params exposure_auto=1,exposure_absolute=20 That seems to not be working as id does not even generate a log entry about setting the values.

Next I tried referencing the settings by id with vid_control_params ID10094849=1,ID10094850=20 This seems to actually do something because it generated this log:

Mar 07 10:28:55 wolpi motion[717]: [1:ml1:Squirrel Ca] [INF] [VID] vid_parms_parse: Parsing controls: ID10094849=1,ID10094850=20
Mar 07 10:28:55 wolpi motion[717]: [1:ml1:Squirrel Ca] [INF] [VID] v4l2_ctrls_set: Set control "Exposure, Auto" to value 1
Mar 07 10:28:55 wolpi motion[717]: [1:ml1:Squirrel Ca] [INF] [VID] v4l2_ctrls_set: Set control "Exposure (Absolute)" to value 20

And when checking v4l2-ctl -L -d /dev/video0 it actually changed the values. However it led to a very overexposed image.

So what I am thinking. I guess it actually switched the camera to Manual exposure mode but then for the exposure value it took the default value of 166 which would certainly lead to overexposure. (Default Value as defined by v4l2-ctl -L -d /dev/video0) No Idea why this is happening.

As a side note I noticed another weird behaviour during testing. Every config value has a default value as shown in v4l2-ctl -L -d /dev/video0. For all values it seems when switching to a different value works fine and it will generate the respective logentries and it will show up in v4l2-ctl but then trying to switch back to the default value through the sliders or "Extra Optiones" it will just straight up ignore the setting and not even generate the log entry to set the value.

As for the Exposure issue, I will probably just write a startup script that will set the value on every reboot or something.
