I have a video (
test.mkv) that I have converted into a 4D NumPy array - (frame, height, width, color_channel). I have even managed to convert that array back into the same video (
test_2.mkv) without altering anything. However, after reading this new,
test_2.mkv, back into a new NumPy array, the array of the first video is different from the second video's array i.e. their hashes don't match and the
numpy.array_equal() function returns false. I have tried using both python-ffmpeg and scikit-video but cannot get the arrays to match.

Getting the same hash requires when writing and reading a video file requires careful attention.
Before comparing the hash, try to look at the video first.
Executing your code gave me the following output (first frame of video_2):
When the input (first frame of video) is:
I suggest the following modifications:
- Use AVI container (instead of MKV) for storing
test_2video in raw video format.
AVI video container is originally designed for storing raw video.
There could be a way for storing raw, or lossless RGB video in MKV container, but I am not aware of such option.
- Set the input pixel format of
Add an argument:
Note: I modified it to
pixel_format='bgr24', because AVI supports
- Select video a lossless codec for
You may select
vcodec='rawvideo'(rawvideo codec is supported by AVI but not supported by MKV).
For getting equal hash, you need to look for lossless video codec that supports
bgr24) pixel format.
Most of the lossless codecs, converts the pixel format from RGB to YUV.
The RGB to YUV conversion has rounding errors that prevents equal hash.
(I suppose there are ways to get around it, but it's a bit complicated).
Here is your complete code with few modifications:

Conda does not work well with large environments in which everything pinned to specific versions (in contrast to other ecosystems in which pinning everything is the standard). The result of
conda env export, which is what this probably is, here also includes the build numbers, which are almost always too specific (and often platform-specific) for the purpose of installing the right version of the software. It's great for things like reproducibility of scientific work (specific versions and builds of everything need to be known), but not great for installing software (there is plenty of flexibility in versions that should work with any package).
I'd start by removing the build pins (dropping everything after the second
= in each line) so that only the versions are pinned. After that, I'd start removing version pins.

You can use scikit-video like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
