Package: python-opencv
Version: 2.1.0-7
Severity: important
After upgrading opencv (libraries and python wrapper to 2.1.0-7), I am no
longer able to read videos: the images extracted are just black. The capture
from a camera is still working but the file capture has stopped working. The
file I am trying to read is a simple AVI movie with no compression and no
sound. The python script attached is used to demonstrated the problem.
To make it work again I have downgraded the following packages using the
2.1.0-6 version found on snapshot.debian.org:
- libcv2.1
- libcvaux2.1
- libhighgui2.1
- python-opencv
