Capturing images with OpenCV 2.2 and Python on Linux (Fedora 15 Beta) -

i have code below ;

import cv import time  cv.namedwindow("camera", 1)  capture = cv.capturefromcam(0)  while true:     img = cv.queryframe(capture)     cv.showimage("camera", img)     if cv.waitkey(10) == 27:     break 

the above code opencv-2.2's own cam capture script python. know nothing wrong program. , can use cam different applications on linux program called cheese. when compile program error below;

(camera:2519): gstreamer-critical **: gst_debug_add_log_function: assertion `func != null' failed  (gst-plugin-scanner:2521): gstreamer-warning **: failed load plugin '/usr/lib64/gstreamer-0.10/libgstbcmdec.so': /usr/lib64/gstreamer-0.10/libgstbcmdec.so: undefined symbol: gst_video_format_new_caps 

i'm guessing there wrong gstreamer. there way fix this? or there problem opencv-2.2 itself? or maybe wrong sample script?

thank time.

that symbol should provided package gstreamer-plugins-base.

check if have installed. if have it, means version of package older opencv 2.2 needs. it's best update entire gstreamer on platform sure.
