In the following configuration:
- Synology NAS DS220+
- Synology DSM 7.3.2
- Synology Plex Media Server 1.42.2
- Plex Web 4.156.0
a library of “Other Videos” type scans the “Originally Available” field to the “1969-12-31” value, rather than fetching a value from the metadata of the parsed file.
To reproduce the bug:
- using the Synology dashboard
- create a “testdata” shared folder
- grant “PlexMediaServer” read only access to “testdata”
- using the “DS File” app
- create the “testdata/2025” subfolder
- load the following MP4 file to “testdata/data”: “file_example_MP4_480_1_5MG.mp4” (available in internet)
- using the Plex Web dashboard
- add a library named “X” of “Other Videos” type pointing to “testdata”
- add a library named “Y” of “Photos” type pointing to “testdata”
- browse the “X” library for the loaded video
- the “Originally Available” field is “1969-12-31”
- browse the “Y” library for the loaded video
- the “Originally Available” field is “2015-08-07 07:13:36”
For the loaded video, the time metadata reported by “exiftool” are:
> exiftool -time:all -G1 -s -a file_example_MP4_480_1_5MG.mp4

Please note that the “Originally Available” field fetched by the “Y” library matches the “CreateDate” tag except for the time part (which could be another bug).
