Video thumbnail problem

I install seafile ce using docker, and set 'seahub_settings.py’according to the official documentation:

ENABLE_THUMBNAIL = True
THUMBNAIL_IMAGE_SIZE_LIMIT = 30
THUMBNAIL_ROOT = ‘/ Shared/seafile/seahub - data/thumbnail/’
ENABLE_VIDEO_THUMBNAIL = True
THUMBNAIL_VIDEO_FRAME_TIME = 5
THUMBNAIL_SIZE_FOR_ORIGINAL = 1024

‘Moviepy’ and ‘ffmpeg’ are installed inside docker. After restart the docker, i can not open the seafile, both web and app,if delete above settings from seahub_settings.py’,it works well again.Why? What is wrong?

in your paste there are blanks in the paths, which might be a problem if the path doesn’t exist

yes,it is just the point.

if just leave it 'THUMBNAIL_ROOT = ‘/haiwen/seahub-data/thumbnail/thumb/’ as the official documentation do,everything is ok.

thanks for your help !

you may change it but need to use a correct path as in your case it would be
THUMBNAIL_ROOT = ‘/Shared/seafile/seahub-data/thumbnail/’
or shared with a lower s

i have tried,both ‘‘/Shared/seafile/seahub-data/thumbnail/’’ and ‘‘/shared/seafile/seahub-data/thumbnail/’’,no use.
