Illegal instruction: 4 when trying to read video from file #15396

Closed zak-al closed 4 years ago

zak-al commented 5 years ago

I'm trying to read a video from a file as such: video = cv2.VideoCapture("path_to_file.avi") However, the program crashes with an Illegal Instruction 4. If the parameter is a path to a file that does not exist, the same error occurs.

I've tried all versions from 3.1.0.4 from 4.1.0.25 on MacOS El Capitan 10.11.16.

Did you use OpenCV from the brew? What does cv2.getBuildInformation() returns?

I installed OpenCV form pip. getBuildInformation returns the following:

3.4.3

This release is old (~1 year ago). Try to upgrade on latest versions or build OpenCV from sources (you need Xcode + cmake and something like brew's python/numpy/ffmpeg)

an Illegal Instruction 4

Stack trace is required.

This release is old (~1 year ago).

I have the same problem with 4.1.0.25.

Stack trace is required.

"Illegal instruction: 4" is the only message printed. There is no stack trace.
