Bug/Issue Description:
G:\PySceneDetect-0.5>scenedetect -i "G:\I2\I.mp4" detect-content list-scenes split-video --copy
Traceback (most recent call last):

Computing Environment:

• OS: Windows 10 Pro
• Python Version: 3.7.0 32bit
• OpenCV Version: Don't know, don't install this.

Additional Information:
I downloaded source code zip file, after extracting I run setup file. I don't install opencv cause I don't have any issue with previous issue as I did same way.

Hi @raj6996;

You need to install the opencv-python module via:

pip install scenedetect[opencv]

If the above methods fail, you can also download the cv2 module from:

https://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv

For 32-bit Python 3.7, you want the file opencv_python‑3.4.3‑cp37‑cp37m‑win32.whl, and install it via pip (e.g. pip install [file]). Also note that you can install PySceneDetect via pip now (e.g. pip install scenedetect).

I'll try to have a more descriptive error message in the program in the next release, thanks for bringing this up. Let me know if you have any issues getting OpenCV installed.

---

Edit: I didn't add OpenCV as a dependency to the setup.py file because the opencv-python package used to not include static libraries, but it seems to now. You can now just type the following to install both:

pip install scenedetect[opencv]

After installing with "pip install opencv-python" command, I got this:

Error: Invalid value for split-video: mkvmerge is required for split-video -c/--copy.
Install the above tool to enable video splitting support.

Then I recalled you told to use MKVmerge.exe on scenedetect folder, so I used portable and copy MKVmerge.exe and it works flawlessly.
by the way, how to use ffmpeg with scenedetect. kindly reply me step by step for being total noob on programing field. thanks.

Hi @raj6996;

You can get both ffmpeg/mkvmerge from here for 64-bit Windows:
https://github.com/Breakthrough/PySceneDetect/blob/resources/third-party/split-video-progams-win64.7z?raw=true

Likewise, you do the same thing (just drop ffmpeg.exe where scenedetect.exe is). I'll try to make the download link a little bit more apparent, and when I finalize the Windows release (portable/installer), it should include both programs for you as well.

If you have 32-bit Windows, you can find download links for ffmpeg/mkvmerge from:
https://pyscenedetect.readthedocs.io/en/latest/examples/video-splitting/

Let me know if this solves it, thanks again for your help in testing the software!!

I recently used 64bit python. so don't know why this I got error!
C:\Python37\Lib\site-packages\scenedetect>pip install scenedetect

Here is error:

@raj6996;

You need to pip install opencv-python as above again.

Thanks Breakthrough, awesome and fast support!
