问题 I want to create a maximum of 30 images from a video (and tile them for a sprite sheet). I've tried using the 'select' with 'mod' but if the total number of frames does not fit neatly into the desired number of images (30) then I sometimes end up with more images, sometimes less. For example if my video is 72 frames long, my 'mod' would be 72 / 30, which is 2.4.

问题 I am redesigning the layout for a interface using python 2.6 and the standard Tkinter included with it. Trouble is that I am noticing some strange behavior, and I am new to Tkinter so this may just be something simple I am overlooking due to inexperience. Here is some example code of how I am nesting frames inside a master frame in order to get the desired layout: import Tkinter as tk root = tk.Tk() master = tk.Frame(root) frame = tk.Frame(master).grid(sticky = tk.W) item1 = "Label One" L1 =

问题 I have a time stamped AVI video file. I want to create images from the frames of the video but I need them to also have a time associated with them as well.

Is it possible to also take the time associated with each frame in the video? My end goal is to sync the time stamp with a GPS track to geotag the images (from the video frames.) 回答1:

问题 I am working on a project with openCV 2.2. I need to do processing on each frame of an AVI file but when I run my code it only grabs the first frame of the file. The CV_CAP_PROP_POS_FRAMES does not seem to be working. Any ideas why not? CvCapture* capture = cvCaptureFromAVI("test1.avi"); IplImage *img = 0; if (!cvGrabFrame(capture)) { printf("Error: Couldn't open the image file.\n"); return 1; } int numFrames = (int) cvGetCaptureProperty(capture, CV_CAP_PROP_FRAME_COUNT); int posFrame = 1;
