DATETIME_FORMAT causes issues with samba on Windows

[mynameisdaniel32]

I updated to 3.1 last night and am finding that since then, all jpegs saved now have cryptic names instead of the timestamps. They are the correct/same boxes with the boxes. Examples below: Before:

those might be temporary files? looks like you are on windows, and I do not have a windows machine to debug on I am afraid

Happened to me. I'll explain what I did.

I access those files through windows smb share to my docker files. Those files are mangled files 8.3 from samba because the file contains colon, ex :deepstack_object_cam2_person_2020-05-18_07:12:37.jpg The actual file is ok in linux, but displayed strangely to windows. I activated mangled names=no to my smb.conf so it displays the file, but still can't acess it because windows does not allow colon in file names. I ended up modifying image_processing.py to dashes instead of colons, ex : DATETIMEFORMAT = "%Y-%m-%d%H-%M-%S" Now it works.

Well glad you managed to get to the bottom of it. Im tempter to implement the DATETIME_FORMAT you suggest, although that will no doubt upset other people who have created automations etc. Will keep this open to take the temperature of how common this issue is

I would certainly welcome the change since samba is much easier to use than HA's file editor when trying to reference images.

fixed in v3.2
