If it is not avi you will need to handle the video with the appropriate openCV codec for your file tyoe.. For example, for an MP4 you could use: fourcc = cv2.VideoWriter_fourcc(*X264) out = cv2.VideoWriter(output.mp4, fourcc, 15.0, (1280, 360) change video_FourCC = cv2.VideoWriter_fourcc(*'XVID') another change can be made after reading the image in line 182: (in yolo.py) return_value, frame = vid.read() if not return_value: break. this solves the issue with getting an empty frame and trying to save it out = cv2.VideoWriter(video_output,fourcc, output_fps, (input_image.shape[1], input_image.shape[0])) AttributeError: 'NoneType' object has no attribute 'shape' Somebody know how can I solve this?

To read an image in Python using OpenCV, use cv2.imread() function. imread() returns a numpy array containing values that represents pixel level data. You can read image as a grey scale, color image or image with transparency. Examples for all these scenarios have been provided in this tutorial Steps: Fetch all the image file names using glob. Read all the images using cv2.imread () Store all the images into a list. Create a VideoWriter object using cv2.VideoWriter () Save the images to video file using cv2.VideoWriter ().write () Release the VideoWriter and destroy all windows. Let's see the code
Example 1: Run a given video file. Example 2: Start a webcam. You can use VideoCapture () method of cv2 library to read and start live streaming. To use cv2 library, you need to import cv2 library using import statement. Now let's see the syntax and return value of cv2 canny () method first, then we will move on to the examples @Monkeydluffy3 try using fourcc=cv2.VideoWriter_fourcc('XVID') or fourcc=cv2.VideoWriter_fourcc('X264') at line 27.In the newer versions of OpenCV, the correct way to use is cv2.xyz rather than cv2.cv.xyz The following are 30 code examples for showing how to use cv2.VideoCapture().These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example OpenCV-Python is a library of Python bindings designed to solve computer vision problems.cv2.cvtColor() method is used to convert an image from one color space to another. There are more than 150 color-space conversion methods available in OpenCV. We will use some of color space conversion codes below

Also habe ich vor ein paar Tagen mit dem Programmieren angefangen und ich habe dieses Problem: AttributeError: NoneType object has no attribute tostring.Ich weiß nicht was falsch ist. #Reads through each frame, calculates the timestamp, places it on the frame and #exports the frame to the output video Just a simple task to get started. To capture a video, you need to create a VideoCapture object. Its argument can be either the device index or the name of a video file. A device index is just the number to specify which camera. Normally one camera will be connected (as in my case). So I simply pass 0 (or -1)
Tracking preserves identity: The output of object detection is an array of rectangles that contain the object.However, there is no identity attached to the object. For example, in the video below, a detector that detects red dots will output rectangles corresponding to all the dots it has detected in a frame 発生している問題・エラーメッセージ.

Use the FFMPEG utility (to read/write/process videos) Test 1: Can we import OpenCV? To confrim that Anaconda is now able to import the OpenCV-Python package (namely, cv2), issue these in the IPython Console: import cv2 print cv2.__version__. If the package cv2 is imported ok with no errors, and the cv2 version is printed out, then we are all good Step 1: Create a Single Object Tracker. A multi-object tracker is simply a collection of single object trackers. We start by defining a function that takes a tracker type as input and creates a tracker object. OpenCV has 8 different tracker types : BOOSTING, MIL, KCF, TLD, MEDIANFLOW, GOTURN, MOSSE, CSRT. If you want to use the GOTURN tracker. The method goes something like this: video = cv2.VideoWriter (filename, codec selection, frames per second, (width, height)) Writing to the VideoWriter can be done with video.write ( numpy array as string ), and the VideoWriter can be closed by using video.release (). And that's all you need to know to convert from PIL to mp4 (or at least. fourcc = cv2.cv.FOURCC(*'XVID') AttributeError: module 'cv2' has no attribute 'cv' FOURCC, プログラマは、始めます、プログラマーによる技術記事の共有に最適なサイト Traceback (most recent call last): File exer1.py, line 15, in <module> H = img.shape[0] AttributeError: 'NoneType' object has no attribute 'shape' となるのですがどう直せばいいのでしょうか 自分が手を加えたのはfor文の中だけなので改善するのはその中でお願いします

Setting Up the VideoCapture and VideoWriter Objects. We need to capture the video from the input path. We will do this using OpenCV. Also, we need to write the final frames with the detected objects to the disk. For that we will need the OpenCV VideoWriter object.
