pylepton_overlay -a 155 error #38

Open basit434 opened 4 years ago

basit434 commented 4 years ago

When i run "pylepton_overlay -a 155" command i get the following error. However both my cameras (pi camera and flir lepton are working fine if i run them individually) When i run "pylepton_capture output.png" this command it also works fine and captures a picture.

i am only facing the issue while running "pylepton_overlay -a 155"

Your traceback is in the picamera library, not this one. Can you confirm if picamera is working on it's own? https://picamera.readthedocs.io/en/release-1.13/recipes1.html

basit434 commented 4 years ago

yeah the pi camera is working on its own

infact both my cameras are working individually at same time the lepton camera is working through lepton module master

I'm not asking if the camera is working, you already said that it does. I'm asking specifically if the picamera library is working, that this project relies on. I've shared a link to examples for this library.

basit434 commented 4 years ago

yeah its working

???

kekiefer commented 4 years ago

OK, given that I've pointed you to the fact that this is a problem the picamera library, did you try searching for related issues there?

https://github.com/waveform80/picamera/issues?utf8=✓&q=is%3Aissue+is%3Aopen+no+buffers+

There are a number of threads with the same error. This one suggests an alternative to using the camera overlay function:

https://github.com/waveform80/picamera/issues/448

Given your time crunch, you should also be looking at other ways you can combine the picamera image and the lepton image. The example given here is just that, an example, and not the only way to get the job done.

basit434 commented 4 years ago

all the examples on https://picamera.readthedocs.io/en/release-1.13/recipes1.html are working fine

@basit434 did this ever get resolved? I am running into the same issue, the picamera lib works fine on its own.

basit434 commented 4 years ago

yeah

@basit434 what was the solution?

basit434 commented 4 years ago

using the alpha transparency it worked i was able to merge both the videos

Ailsamly commented 4 years ago

hi, I have the same problem, how did you solve it? @basit434 @hrdunn

hrdunn commented 4 years ago

@Ailsamly yes I used a different library, this lib is garbage, out of date, and borderline deprecated, I managed to get it to work with a lepton 3.5 using the lepton3-dev branch. I made a few mods and I think I commented out the overlay. If you have a breakout board take a look at Lepton Module a C lib, but don't let that scare you, I never wrote C before and got it working or if you have a purethermal board (so much easier to work with) take a look at purethermal1-uvc-capture a python library that you can extend

@hrdunn Thanks very much for your quick and kind reply! But I am really new to this as well as programming.. could you please specify more about your steps? I am also using a lepton 3.5 with the latest breakout board. Thank you!!!

hrdunn commented 4 years ago

@Ailsamly sorry dude I wish I could, I deleted the modified library and ditched the breakout board back shortly after getting it to work in May so I don't have my steps that got it to work.

basit434 commented 4 years ago

its ok
