安装
install from pypi
pip install extract-video-ppt
or local
python ./setup.py install
or local user
python ./setup.py install --user
使用
evp --help
evp --similarity 0.6 --pdfname hello.pdf --start_frame 0:00:09 --end_frame 00:00:30 ./ ./test.mp4
- similarity: The similarity between this frame and the previous frame is less than this value and this frame will be saveed, default: 0.6
- pdfname: the name for export pdf
- start_frame: start frame time point, default = ‘00:00:00’
- end_frame: end frame time point, default = ‘INFINITY’
convert to exe
为了方便使用，使用pyinstaller转化成了exe文件，在转换过程中遇到以下问题：
提示ImportError: OpenCV loader: missing configuration file: ['config.py']. Check OpenCV installation
Solution：在pyinstaller时添加一下opencv的路径即可：pyinstaller -w xxx.py --paths="xxx\Lib\site-packages\cv2"
######
Solution:
pip uninstall matplotlib
pip install matplotlib==3.1.1
pyinstaller -F XXX.py
找到.spec文件，将其中的hiddenimports=[]修改为hiddenimports=['matplotlib']，然后：
pyinstaller -F XXX.spec
此时再运行就可以了，虽然运行时会有Warning，但不影响。
