issues installing on PI 3 B+
-
yes its running on standalone not sbc
-
let me do point by point
Can you confirm that, from a browser (not on the pi), that this url results in the display of video ?
http://10.0.1.110/streamyes
What streaming software are you using? Does it generate any error messages ?
answer :motion ver 4.3.2
Are any images being created like: /home/pi/DuetLapse/raspberrypi/10-0-1-126/<>/Camera1_00000001.jpeg
answer :yes 1 image
answer : on the duetlapse also says 1 image
if so - what happens when you try to open one ?
answer : it open no issues an image of the camera from the room am in it
Assuming you are streaming video OK ...
it is ok
ffmpeg -y -i http://10.0.1.110/stream -vframes 1 ~/test.jpeg
it takes a pic and save it under home 1 pic yes
ou should get errors the same as above. Do you ? If yes - try reinstalling ffmpeg. Its possible there are some library dependency conflicts.
answer : yes i get the same as above while running it looks like something with the config of the ffmpeg maybe it need only to be disabled
question : is the 10.0.1.110:8082 suppose to show an image when it takes one? i mean the first page is it suppose to show the live pic ?
why is it only taking one pic only while printing it suppose to take 1 every 20 sec no ?
see below
45 layres and only 1 pic
-
i mean the first page is it suppose to show the live pic ?
No - it displays the last still image it has capture. In this case - it has not captured any images.
Do you have motion set to stream ? I.e. when viewing in a browser does http://10.0.1.110/stream show live video (as opposed to a single static image)?
What is happening is ffmpeg is not able to capture from the motion feed. So either a problem with ffmpeg or motion or both
Assuming that the motion feed is video. What happens when you run
ffmpeg -y -i http://10.0.1.110/stream -vframes 1 ~/tes[x].jpeg(changing [x] to get different images).Note that the command above is subtly different to the one used in DuetLapse - which may not be supported by the ffmpeg version on your machine (although its supposed to be). But one step at a time ...

hi here is the answers
Do you have motion set to stream ? I.e. when viewing in a browser does http://10.0.1.110/stream show live video (as opposed to a single static image)?
answer : yes live video
Assuming that the motion feed is video. What happens when you run ffmpeg -y -i http://10.0.1.110/stream -vframes 1 ~/tes[x].jpeg (changing [x] to get different images).
answer :it take a pic and i can open that pic and i change the name to anotherone in the link and redo it and it save another pic
Note that the command above is subtly different to the one used in DuetLapse - which may not be supported by the ffmpeg version on your machine (although its supposed to be). But one step at a time ...
answer : yes it works the same as you gave me it save a picture every time i do it
my config now is
-basedir /home/pi/DuetLapse
-duet 10.0.1.126
-port 8082
-seconds 30
-detect none
-weburl1 http://10.0.1.110/stream
-verbose
-camera1 streammaybe that camera1 stream is wrong ?
it seem the motion is saving video files see below the motion log
and maybe the format of the streaming need to be changed to mjpeg so the Duetlapse can see it but what i need to do to make this happen in motion ? But that is the job of ffmpeg no??
another note i find opne image always under 10-0-1-126 which is camera1_0-000001.jpg if i delete it it takes another pic with the same name but only one pic same name is this normal ? what is the output looks like a clip with still images or images to be a clip in another program ?
-
There should be sequentially named images in the "capture" folder. The fact that there is only one is a symptom of the problem.
Try this version. Its a long shot but I have removed a portion of the ffmpeg command so that it is the same as the one I had you manually test. If that does not change anything, then I think the issue is with motion.
Ideally - you want motion to be configured to output jpeg or mjpeg. I do not know what it streams by default. Also - I would disable the motion detection (just to take a variable out of play).
I used motion a long time ago but the version at that time used way too much CPU - so I developed videostream. That has the disadvantage of using opencv which can be tricky to get installed. Bottom line, I cannot help you directly with motion. -
so let us do videostream then but you know there is a part fails what i need to to ?? do you have a solution for that ? if less cpu then we do that but tell me what i need to do exact i will do it
i used the last ver you gave me it does the exact same thing one image same name the only difference in this one when the print cancel or stoped it does not force the duetlapse to stop it keep running idle

If you are using a pi camera (ribon cable) then videostream can be used without opencv (which I mentioned can be reluctant to install). To use a USB camera requires opencv.
The version on github tries to import opencv. The version below has a small change and should not try to install opencv. To use this version you MUST use the -pires and -pistream options. This will use the pi libcamera libraries. I've not used it this way for quite a while so do not know if the libraries have changed much.
i used the last ver you gave me it does the exact same thing one image same name the only difference in this one when the print cancel or stoped it does not force the duetlapse to stop it keep running idle.
The difference is incidental - the change I made was just to the ffmeg call.
If videostream does not work, I have one other trick up my sleeve.
-
i made a dir called videostream and i put the file you sent videostream.py there and i ran python3 ./videostream.py -port8081 & -pires -pistream
and i got this error no module named imutilswhat i do ?
i installed imutils but now am getting another error for cv2
-
You tried to run videostream without -pires etc. so it tried to use opencv (cv2 is its internal name).
-
Also best to run without & at end when you are testing.
-
Also - please read the instructions especially on -pires settings and how to determine them.
-
i did try with and without the & and with the option -pires and -pistream and it gives the same results
its asking for cv2 see belowi will try to install the opencv i see now the notes you refered to it i will give it a try
a lot of errors see the log file down and as soon as i open the address 10.0.1.110:8081/stream i get this msg repeating " empty frame detected

Please read the documentation carefully. -pires requires something other than blank input
-pistream can usually be omitted
The documentation is here:
https://github.com/stuartofmt/videostream/blob/master/videostream on Raspberry.md
Try something LIKE
python3 ./videostream.py -port 8082 -camera 0 -rotate 180 -debug -pires "--width 800 --height 600"tou can also try
libcamerify python3 ./videostream.py -port 8082 -camera 0 -rotate 180 -debug -pires "--width 800 --height 600" -
am using USB camera now
and when i use this one
python3 ./videostream.py -port 8081 -camera 0 -rotate 180 -debug -pires "--width 800 --height 600"
i get this
-
As I said a while back - I don’t have access to my test septup. This is too hard trying to do it remotely. I’ll pick it back up in the new year and we can try again. Happy New Year !
-
ok thanks , happy new year to you too
-
As a follow up. Go through the procedure described here
https://github.com/stuartofmt/Pi-Notes/blob/master/Resolution Testing.md
As an observation; getting camera setting that work is largely trial and error. Different combinations of computer, operating system, streaming software, camera type ( usb vs pi) , camera libraries etc
Finding working combination requires an approach that is methodical (one thing at a time), consistent (use only the appropriate commands for the type of camera). Jumping from one approach to the other creates false trails. Even for a camera that is working, not all the resolutions ( for example) that it reports as supported will necessarily work.
-
is it easier to install the duetlapse on videostream on window 10 ? or a mac ?
-
I’ve never tried it on the Mac.
Otherwise try it and see. Same potential issues with opencv. It worked fine in the past -
Merry Christmas
i tried on pc and same exact issues so am back to PI and the ribbon cam will keep trying until you have time
