Access IP Camera In Python OpenCV


Answer :

An IP camera can be accessed in opencv by providing the streaming URL of the camera in the constructor of cv2.VideoCapture.

Usually, RTSP or HTTP protocol is used by the camera to stream video. An example of IP camera streaming URL is as follows:

rtsp://192.168.1.64/1

It can be opened with OpenCV like this:

capture = cv2.VideoCapture('rtsp://192.168.1.64/1')

Most of the IP cameras have a username and password to access the video. In such case, the credentials have to be provided in the streaming URL as follows:

capture = cv2.VideoCapture('rtsp://username:password@192.168.1.64/1')

This works with my IP camera:

import cv2  #print("Before URL") cap = cv2.VideoCapture('rtsp://admin:123456@192.168.1.216/H264?ch=1&subtype=0') #print("After URL")  while True:      #print('About to start the Read command')     ret, frame = cap.read()     #print('About to show frame of Video.')     cv2.imshow("Capturing",frame)     #print('Running..')      if cv2.waitKey(1) & 0xFF == ord('q'):         break  cap.release() cv2.destroyAllWindows()

I found the Stream URL in the Camera's Setup screen: IP Camera Setup Screen

Note that I added the Username (admin) and Password (123456) of the camera and ended it with an @ symbol before the IP address in the URL (admin:123456@)


The easiest way to stream video via IP Camera !

I just edit your example. You must replace your IP and add /video on your link. And go ahead with your project 

import cv2  cap = cv2.VideoCapture('http://192.168.18.37:8090/video')  while(True):     ret, frame = cap.read()     cv2.imshow('frame',frame)     if cv2.waitKey(1) & 0xFF == ord('q'):         cv2.destroyAllWindows()         break

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
