Hi guys,

Iam trying to build OpenCV with CMake.


While Downloading opencv_ffmpeg.dll through CMake, it causes an file DOWNLOAD HASH mismatch.

for file: [C:/opencv_source/3rdparty/ffmpeg/downloads/89c783eee1c47bfc733f08334ec2e31/opencv_ffmpeg.dll]

expected hash: [89c783eee1c47bfc733f08334ec2e31c]

actual hash: [d41d8cd98f00b204e9800998ecf8427e]

status: [7;"Couldn't connect to server"]

Is there any solution to solve these issue?
