if not works.check_files( REQUIRED, TESTNAME+FORMAT ):
return false
filename = PREFIX+FORMAT+EXTENSION
video = cvCreateFileCapture(PREFIX+FORMAT+EXTENSION)
if video is None:
sys.exit(1)
works.set_file( TESTNAME+FORMAT )
return True示例2: image_ok
def image_ok( EXTENSION ):
# check requirements and delete old .works file
WORKSNAME = TESTNAME+'.'+EXTENSION
if not works.check_files( REQUIRED, WORKSNAME ):
print "worksfile "+WORKSNAME+" not found."
return False
image = cvLoadImage(PREFIX+'.'+EXTENSION)
if image is None:
return False
else:
works.set_file( TESTNAME+EXTENSION )
return True示例3: cvCreateFileCapture
# name of this test and it's requirements
TESTNAME = "cvGrabFrame"
REQUIRED = ["cvCreateFileCaptureRGBA"]
# needed for sys.exit(int) and .works file handling
import os
import sys
import works
# path to imagefiles we need
PREFIX=os.path.join(os.environ["srcdir"],"../../opencv_extra/testdata/python/videos/")
# check requirements and delete old flag file, if it exists
if not works.check_files(REQUIRED,TESTNAME):
sys.exit(77)
# import the necessary things for OpenCV
from highgui import *
from cv import *
# create a video reader using the tiny video 'uncompressed.avi'
video = cvCreateFileCapture(PREFIX+"uncompressed.avi")
# call cvGrabFrame to grab a frame and save return value
res = cvGrabFrame(video)
if res==0:
print "(ERROR) Couldn't call cvGrabFrame()."
