我使用的是 Ubuntu 16.04 和 Anaconda 3.5。我成功地從 git 儲存庫建立了 OpenCV 3.1.0。我的make指令如下
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_C_EXAMPLES=OFF \
-D WITH_FFMPEG=ON \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules \
-D BUILD_EXAMPLES=ON ..
>>> import cv2
>>> print (cv2.__file__)
/home/adam/anaconda3/lib/python3.5/site-packages/cv2.cpython-35m-x86_64-linux-gnu.so
我的 ffmpeg 配置如下：

但是，我仍然無法使用視訊功能：
python3 video.py /home/adam/opencv/samples/data/tree.avi
Warning: unable to open video source: /home/adam/opencv/samples/data/tree.avi
我已經搜索了幾天，但沒有找到任何有效的方法並允許我處理影片。任何幫助將不勝感激。
