Arch Linux

Description:
Several of my applications that use opencv started crashing recently and the stack trace points to libavutil.so.55 provided by the recently updated ffmpeg package.

Rebuilding the opencv package with its current PKGBUILD solved the issue.

opencv 3.2.0-1
ffmpeg 1:3.3-1

Steps to reproduce:

In python interpreter run:
import cv2; cv2.VideoCapture('/path/to/video_file_orgif.gif')

Using any animated gif file should result in segmentation fault with following stack trace:
