io.Video hanging indefinitely on load
Hello, I'm trying to get skimage working with video, and I'm using a relatively small video to test the functionality I need. If I run the following code (with a video I know to play in multiple players) it seems to hang python. import os from skimage import io ** Message: pygobject_register_sinkfunc is deprecated (GstObject) video_path = os.path.join(os.getcwd(),'test.avi') data = io.Video(source = video_path) as in, I've let it run for 5 + min on a 2.5 MB file and had to kill the python process. I'm running OS X 10.9.1 and I have: Python 2.7.6 :: Anaconda 1.7.0 (x86_64) skimage 0.8.2 Gstreamer 1.2.3 from binary at http://gstreamer.freedesktop.org/ and gst-python010 installed In case it matters, I installed gst-python via: $ brew tap homebrew/versions $ brew install gst-python010 I would appreciate any suggestions or recommendations as to how to determine where the error is, and then how to go about correcting it.
Sounds like you’re using Gstreamer. If you have access to OpenCV, it would be informative to see if the same file is opened correctly via the OpenCV backend, with data = io.Video(source=video_path, backend='opencv') I’ve heard our Gstreamer backend could use some attention… On Wednesday, February 12, 2014 5:36:01 PM UTC-6, !link wrote: Hello,

I am using gstreamer, because when I tried to install OpenCV (version 2.4.7.1) via brew and then test to see if it works python segfaulted. Maybe I need to find a different source for OpenCV. $ brew install opencv ==> Downloading https://github.com/Itseez/opencv/archive/2.4.7.1.tar.gz Already downloaded: /Library/Caches/Homebrew/opencv-2.4.7.1.tar.gz ==> Patching patching file cmake/OpenCVFindOpenNI.cmake ==> cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/Cellar/opencv/2.4.7.1 -DCMAKE_BUILD_TYPE=None -DCM ==> make ==> make install Warning: Could not fix libpython2.7.dylib in /usr/local/Cellar/opencv/2.4.7.1/lib/python2.7/site-packages/cv2.so 🍺 /usr/local/Cellar/opencv/2.4.7.1: 224 files, 40M, built in 2.7 minutes $ python Python 2.7.6 |Anaconda 1.7.0 (x86_64)| (default, Jan 10 2014, 11:23:15) [GCC 4.0.1 (Apple Inc. build 5493)] on darwin Type "help", "copyright", "credits" or "license" for more information.
