Accessing USB Devices and Webcams with OpenCV and Python

[@zakyvids6566]

Hi Nick, I’m new to your channel and I appreciate the videos you bring to us they are interesting informative and teach new innovative ways to learn new projects. I do have a request which is to consider making a 30-45 minute python crash course that covers the basics of python programming/or basics to get us started making projects in python etc

[@justanaquarius320]

thank you so much, you always expland everything clearly!!! good job

[@extribolo]

Quickly, Smart and Complet...!!! Thanks Nicholas

[@venkatesh2788]

Please teach me how to freeze a model to convert into tensorflowjs

[@jliu83]

Hi Nicholas, what model of webcam do did you use for this? The footage is quite good.

[@dogukantombul1045]

what if my camera is connected via ethernet cable

[@markwalterbilaro7007]

can you have a tutorial too how to access the depth camera and IR camera, like of what ScanMax M5 ToF camera capable of?

[@TheNotVisible]

best tutorial over the internet

[@Love_roundabouts]

Amazing mate!! Extremely useful!

[@ehsankhosrojerdi9815]

Hi Nick. Thanks for the great tutorial. If I want to compare consecutive frames from camera and processing takes a little while, what happens when it comes to the next frame analysis? Does it start analyzing from the current frame and miss those passed during the analysis?

[@innovation3027]

Hi thanks for the helpful video, I am trying the same thing but the capture time is 14 seconds and I want to shorten it. if I use my computer webcam its only 2 seconds. Im not sure what the problem is may I know the best way to speed it up.

[@umeshbakre770]

Happy Diwali Nick !!

[@jbelmont72]

First, I pray you are faring better. Loss of a parent is difficult. Second. I want to use argparse to control my programs with mediapipe. Want to use different classes in my master program. TO do so, I think I need the IP_URL address for my web cam even though I have it connected by USB and oftentimes just use my continuity camera on my MAC. Can you suggest what the -I -input path would look like and how to find it? thank you.

[@ancomurg]

How can I get a list of video devices connected included the camera? For instance: I would like to get a usb video capture conected. Thanks for help me.

[@terrains-en-pente]

yes I want to do the same thing I can't find a tutorial

[@jakewhitworth3116]

Do you use jupyternotebook outside of computer vision? Like for example the work you do at IBM, is most of that done in jupyter?

[@adarshd249]

Happy Diwali Nick Thank you for speeding the light of knowledge 🪔🤝🤝

[@NicholasRenotte]

Happy Diwali Adarsh!

[@texasfossilguy]

Video request: please show how to do an analysis on an image mask as a second level analysis. For example if it identifies a Red ball from a ball pit, is the red ball rough or smooth? A second tier level analysis? Also shape of the mask outline would be an interesting criteria as well or things like that.

Can you detect quiality of a fruit? i mean more than just classification but measure colour

[@ademadani2638]

Can you tell me what brand webcam you used?

[@애기콩-h5e]

Thank you for the good video. I succeeded in connecting. But why is my screen black? Can't I connect to my Photo Booth in MacBook? Do I have to buy an external camera?

[@xinglinjiang4952]

hello. At what point the physical camera start to work? i am try to precisely control the starting time of two identical cameras so they can be frame synchronized for stereo vision. first i would like do it by software. but i can also div the hard ware (the easist way should be starting the power supply at the same time by a shared switch).

[@fabcraeyz3914]

I cannot connect my camera to my google collar sheet? I already looked at stack overflow, but could not find a solution. Any ideas?

[@NicholasRenotte]

Got any errors for me?

[@surajwagh3654]

Can you used Baumer industrial camera using neoapi python ?

[@ryanhsu6283]

It's a great video. Thank you for your sharing. I have a question. If the camera is connected through network interface card(Intel chip). what should I code it? Thank you.

[@MvGamingFacts]

Can you do a tutorial for uploading a model into a cv2 and run it with gui pyqt or tkinter? Thanks!

[@dhxbcmd]

thank you for your lecture wonder Start video recording key = 'F5' Video recording pause key ='F6' End section (off) key ='q' If you can tell me how to do it, thank you.

[@khanhduyphamtran9059]

Please make a video about stereo camera and stereo vision

[@NicholasRenotte]

New projects kicking off in a few weeks!! Will take a look at the oakd maybe.

How to display the time date in live webcam window

[@pavanim6258]

Thanks for your Super and clear explanation.I've a question regarding text capture in an application in python.How can I identify name from the application image?

[@FiniX97_]

is it possible to display multiple cameras through python? could you teach us?

[@morbius125]

cap=cv2.VideoCapture(0) is not working on my mac "kernel has died will restart automaticaly" Please help

[@Powercube7]

Thank you Nick, very cool

[@moralexbme]

I have a fisheye camera that has 7 different sources, each source representing a different angle. How can i make a control for it through my .py code so that, when i run this as a .exe file, i can choose which source to view?

[@vietnguyenquoc6366]

Hi. I want to get name of webcams. Can you help me ?

[@AdamCurtis62]

Thanks for the great tutorials, I have been following along but using Jupyter notebooks inside of VSCode but have noticed that when I use cv2.destroyAllWindows it fails to close the window unless I also add cv2.waitKey(1) after that line. I do use cv2waitKey() early in my code as part of the if statement which successfully ends the loop. Just wondering if this is a VSCode weirdness, not that it is a drama to add the extra line but I would just like to know what is causing this issue. Thank You

[@NA-cw4pj]

Hi Nicholas, Excelent Video!! but i have a special question! what if I have a vcr recorder, and an easy cap, but i don´t have the correct program for the easy cap, can i choose this device to digitalize my vhs?! Please & TYSM!

[@gazorbpazorbian]

dude, just discovered your channel and I'm amazed, :D you should do stuff on the jetson nano or raspberry pi. I mean, although is basically the same thing, it would be interesting on the limitations of the hardware and stuff you could do with it.

[@ArunKumar_237]

thank you for diwali wishes sir you are a great teacher

[@MB.-11]

Can I access others devices?

[@rishikatna8328]

[@ngynbngoc]

Idk why but I tried 60 times and it still couldnt connect to my external camera?? please help

[@hesron-sam]

Good day sir, i have watch the yolo tutorial with pytorch on your channel... May i request simple video on how do we can deploy the code into app or web in real time.... some say that it can be done using flask.. 😅

[@Chetan_Hansraj]

Happy Diwali bro god bless

[@vinayakrajurs]

Great video Nick, Can you do a time series forecasting for attention based sequence to sequence model maybe sometime in the future, i really loved the stock prediction video using RL and i wanted to explore more models for Times series Forecasting. Thank you for uploading great Videos man.

[@pankajray5939]

Love you're videos

[@MTB.J]

First thank you so much. With this code I can use any external camera not only the webcam?

[@terrains-en-pente]

no, this tutorial is not suitable for using an external camera

Hi nick! Thankful for your tutorials! I am following this but I am running Jupiter Notebook thru Docker and I have tried 1~10 for the VideoCapture and I can't seem to make it work. just tell's me "[ WARN:0@213.087] global /io/opencv/modules/videoio/src/cap_v4l.cpp (876) open VIDEOIO(V4L2): can't find camera device" ?

[@pettjols]

This channel is exceptional! Could you also make a video on the new Pose Detection in the Google ML Kit, interested in how you would do it and your views on the new version :D

[@venkatesh2788]

Sir if I convert the tensorflow transfer learning model into tensorflowjs. I get this error 💥This may due to the following reason: 1. The layer is defined in python, in which case it needs to be ported to tensorflowjs or your JavaScript code 2. The custom layer is defined in JavaScript, but is not registered properly with tf.serialization.registerClass Please 🙏 reply 😭

[@lloydchan9606]

beautiful

[@jpsst9]

Can you add discord admin pls

[@burhanuddindewaswala6888]

i have a doubt is there a chance that the index at which web cam is configured taht can channge once you restart the systems example if we can access the camera via cv2.videocapture(0) then post restart we are able to access the webcam by cv2.videocapture(1)
