@Ricolk

Thanks, I didn't think of that. I haven't formatted the old card, I'll load it back up later.

@Gary Littlemore

I’ve just done a fresh install on the new bigger MicroSD card and I’m using the internal motion setting, I’m getting recordings with long times 200s

You could recover your setting from your old SD if you did't format it.

Hello,

Is anyone else having/have had the same problem as me?

The mp4 recordings (Just the recordings) are blurry. The images are not.

I haven't got a blur image effect enabled and the camera is in focus.

Any ideas?

Thanks

I haven't got a blur image effect enabled and the camera is in focus.

Interesting, I haven't seen anything like that. What are your video and still image resolutions set to? Can you post the contents of your uconfig file?

I've manage to get hold of another system to try the video on, and it's not blurry. Must be some sort of video effect enabled on the player?


Sorry for wasting your time and thanks for your help.

Good day anyone.

I am trying to add a user button.

I have renamed userbuttonsD to userbuttons, modified file to:

Code: Select all

#User buttons definitions
#maximum of six buttons
#button name,macro,button styles,other attributes
Button One,test.sh,btn btn-danger btn-lg,style="width:50%" autofocus
Warning Button,button2.sh,btn btn-warning btn-lg,style="width:50%"
Success Button,button3.sh,btn btn-success btn-lg,style="width:50%"

put test.sh into macros directory.

Then I am starting RPI CAM Webinterface, I can see a new userbutton. But then I pressed it, nothing happened. Then I manually start test.sh i see a result.
Help please

UPD The answer is - you should give permissions to test.sh to execute by "others"

I want to control GPIO from RPI-CAM Webinerface

I have succesfully add 2 new buttons wich starts two scripts - one of them set GPIO TO HIGH and other one to LOW.

Then I am executing this scripts as a user PI, everything works fine.

But then I am executing this scripts using buttons from RPI-CAM Webinerface, NOTHING HAPPENED.

UPD www-data user have permissions to write to GPIO

Solved, after this viewtopic.php?p=1448286#p1448286

reinstall & reboot

Thanks for rpdom!

I have several wildlife cams set up outside, within a wifi range that give me adequate (but not stellar) throughput. One viewer can watch the live feed at HD resolution with no problems, but if three or four browsers/devices are trying to watch simultaneously it gets stuttery.

I'd like to figure out a way to proxy the feed somehow so multiple people can view simultaneously (in other words, there's one stream going from the cam to some kind of proxy server over slow wifi, and then there's multiple simultaneous streams going from the proxy server to multiple viewing devices over fast wifi and/or wired ethernet).

Does anybody have a recommendation for a place to start on this?

Hi,
I am unable to do video capture by sending a 'ca 1' to FIFO. I remember I could do this, when I last used a few months back.

I am not starting the scheduler (php schedule.php)
1) I am only starting raspimjpeg:
sudo su -c raspimjpeg www-data

I see that the last two lines in stdout are:
MJPEG streaming, ready to receive commands
send smd 9

(shouldn't there be a line 'starting command loop' )

2) Then I do, echo -n 'ca 1' > /var/www/html/FIFO

No video capture done. It does work if I start the scheduler. Has something changed? Can i send 'ca 1' without scheduler?
Thanks

Morning

Can't remember if I've asked this before but I'm looking at this again and can't work out the answer.

I'm using Smartthings with ActionTiles and trying to add my camera feed. It's asking for the feed URL.

If I use http://my.ip.add.ress/cam/min.php then I just get a broken image < This works in the browser, not in ActionTiles

If I use http://my.ip.add.ress/cam/cam_pic.php then I get a static image that, when I refresh, updates

I've asked in the ActionTiles forum and they've come back with this:

"You need to be sure to have to URL for the plain MJPEG stream..."

So, what would that be, please?

Best regards
Andy

Have you tried http://my.ip.add.ress/cam/cam_pic_new.php ?

I have indeed. But that only seems to show the latest image as far as I can remember

cam_pic.php returns a static image; cam_pic_new.php returns a stream. My (imperfect) understanding is that this is "the plain MJPEG stream". From the docs at https://elinux.org/RPi-Cam-Web-Interface#Data_Flow :

Code: Select all

These captures may be accessed via URLs on the Apache Web server. cam_pic.php process returns the latest one and cam_pic_new.php merges them into a mjpeg stream.

Hello!

Is it possible to start and stop recording from the command line?

[ras07]

Is it possible to start and stop recording from the command line?

You can do many things (including start/stop recording) from the command line by writing to the FIFO queue. For example to start recording: (Note that your directory name may be different depending upon your installation)

Code: Select all

echo 'ca 1' > /var/www/FIFO

And to stop:

Code: Select all

echo 'ca 0' > /var/www/FIFO

While this command will capture 25 seconds of video and then stop:

Code: Select all

echo 'ca 1 25' > /var/www/FIFO

You can see a list of available commands by clicking on the 'Edit schedule settings' button, and then 'Command reference'.

Doh! My mistake. I think I'd messed with this for so long that I couldn't see the wood for the trees. Just went back and tried again and it works!

Thank you! Sometimes it needs a fresh pair of eyes to sanity check things.

So I'm having an issue. I have two cameras, both running the interface. I have multi view set up fine, and I also have an external HDD attached to one of the cameras, but I can't figure out how to use the fstab bind to bind the directory of stored video to my external HDD. I'm sort of a noobie when it comes to this stuff. I found the storage location for pics and video in the config file for the cam web interface, but I'm just not sure what I need to append to the fstab file. Can someone help me?

I'd recommend against changing the directories in the Cam Web Interface configuration. There are several settings you have to change and some of them can get overwritten during updates; also, it doesn't seem to work right unless it's off your base Cam Web Interface directory anyway. Instead, just mount the external drive directly to your existing media directory.

It'll depend on your exact setup, and especially your hard drive format, but your fstab should look something like this:

Code: Select all

/dev/sda1       /var/www/html/media        ntfs defaults,noatime,auto,nofail,uid=www-data,gid=www-data,umask=0022       0       0

• /dev/sda1 might be different; you can probably figure this out by executing sudo blkid (look for the device that looks like your USB drive; if it's not obvious, run the command with and without the drive plugged in). Be sure to use sudo or you may only get partial results (which probably won't include your USB drive).
• /var/www/html/media : this is your existing media directory (may be different if you installed it somewhere other than html).
• ntfs : this is the drive format; blkid should tell you this too (look for the TYPE field).
• defaults,... : These are the mount options; you may need to change some of these depending on your drive format, but these are a good place to start.

Make sure your media folder is empty before you mount the drive. (Mounting over the top of files won't delete them, but they won't be accessible with the drive mounted.) Also, you may need an additional package if the drive is NTFS (aka Windows format). If you mount it as above and you can't write to the drive, run sudo apt-get install ntfs-3g, and then change ntfs in the above fstab line to ntfs-3g. (Sorry, I can't remember exactly when this is necessary and when it isn't.) If you're only ever going to use the drive for this, I'd just format it EXT4.

Hi,

could anyone give me a hint why my motion detection is not taking any pictures at all?

I got a raspberry pi w zero with a raspberry pi cam and installes the latest rpi cam control v6.4.50.
Taking pictures, Videos and timelapse work like a charm.

But when I configure
Motion detect mode: 'internal'

and press 'motion detection start' no pictures are taken at all.

When enable 'Motion Vector Preview:' I can see lots of motion detected, but anyway no picture or video is taken....

Do I have to configure the action somewhere else, what to do if a motion is detected?

Thanks alot!

Cheers

Add %c %f to your annotation. The first value represents motion; when it gets above the value you have set for motion threshold, it should start recording.

What do you have set for noise level and threshold in your motion settings?

Can you post the contents of your uconfig file?

[4920441]

Hi,

Add %c %f to your annotation. The first value represents motion; when it gets above the value you have set for motion threshold, it should start recording.

Erm, thanks for the hint, but where should I put it? I am currently a bit out of webinterface-context:-)

My uconfig file reads as follow:

rotation 180
video_width 1296
video_height 972
vector_preview 0
motion_external 0

so, nothing special at all.

Thanks a lot!

Cheers

In the web interface, under Camera Settings, the 4th item is Annotation. The default is

Code: Select all

RPi Cam %Y.%M.%D_%h:%m:%s 

Just set it to

Code: Select all

RPi Cam %Y.%M.%D_%h:%m:%s %c %f

You will see the values on the image. The first number will bounce around when there is motion, and if it gets above the threshold (the threshold default is 250) the second number should start to increment and video recording should start. The second number represents how many frames have been captured. Your uconfig file looks fine.

Has anyone set this up with a captive portal?

I have it setup in apache and am currently building one in lightpd.

The RPi is its own hotspot. I would like for it to force me to the appropriate web page when I join its network and open a browser.
And not have to enter the appropriate ip address.
This is to make it easier for some of my not so tech savy friends.

[ras07]

Has anyone set this up with a captive portal?

I haven't heard of anyone doing that, but it's a great idea. There are several captive portal options for the Pi that I'm sure would work, but really, since you already have a web server set up via RPi Cam Web, I think all you really need is a very minimal DNS server (such as DNSMASQ) that's configured to always return your Pi's IP no matter what. If you Google "DNSMASQ captive portal" it looks like a one-line config would do the job. If you make it work it would be great if you could detail the process here.

On a semi-related note, I've set up my system to point most visitors to a minimal view (just the MJPEG stream, no controls at all) while still having the full interface on a separate URL for my purposes, with no passwords on either interface. It's not designed to be secure of course (everything's behind a firewall anyway) but it does let visitors easily view it without me worrying about someone accidentally changing settings or deleting videos. If that would be useful for your situation let me know and I'll write it up.

[Rednecknerd]

ras07 Thanks for the input. I may have been making it harder that it has to be.

I like your idea of two urls. I may use that for a future project.
This one is for them to play with.

Think cheap gopro with no sound and ridiculous battery life. 3~4 hours.
