剛剛接觸python 所以有點不太熟有上網查了一下做法我的程式碼如下 import cv import os, glob,sys path = 'C:\image\' video = cv.CreateVideoWriter('output.avi',-1 , 10,(2456,2936), 1) for infile in glob.glob( os.path.join(path, '*.jpg') ): img = cv.LoadImage(infile) cv.WriteFrame(video, img) del video 但是這樣合成出來的影片大小都是0kb 是哪裡做錯了嗎? 另外要讀圖片是不是只能用opencv裡的涵式讀? (ex:cv.LoadImage) 而不能用PIL裡的Image.open 麻煩大家了 ============================================================ 謝謝大家幫忙重寫一次給之後有需要的人安裝opencv-python : opencv-python-2.4.8.win32-py2.7.exe (http://ppt.cc/8-Cs) (沒安裝 codec 要安裝一下) import cv import os, glob impath = 'C:/image/' # image path Fname = 'output.avi' # output file name FPS = 10 CODE_TYPE = cv.CV_FOURCC('X','V','I','D') # 註一 Fsize = (height,width) #frame size video = cv.CreateVideoWriter(Fname, CODE_TYPE, FPS, Fsize, is_color = 1) for infile in glob.glob( os.path.join(impath, '*.jpg') ): img = cv.LoadImage(infile) cv.WriteFrame(video, img) del video 註一 CODE_TYPE = 0 => no compression CODE_TYPE = -1 => jump out a msgbox asking for the compress formate ======================================= CODE_TYPE = cv.CV_FOURCC(X,X,X,X) ======================================= cv.CV_FOURCC('H','F','Y','U') # HuffYUV cv.CV_FOURCC('D','R','A','C') # BBC Dirac cv.CV_FOURCC('X','V','I','D') # MPEG-4 Part 2 cv.CV_FOURCC('X','2','6','4') # MPEG-4 Part 10 (aka. H.264 or AVC) cv.CV_FOURCC('M','P','1','V') # MPEG-1 video . . . . -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 128.122.72.56
