1.) I add a thumbnail and some tags to a single mp4 file Steven.mp4
2.) Add *generic* video (Steven.mp4) file to emby media folder
3.) Spin up docker test container
4.) Add library, check Nfo metadata saver, Screen Grabber Image fetchers
5.) Execute Scan library Task
6.) Execute Chapter Image extraction
1.) The file is added to the library but:
2.) None of the tags are read
3.) No Nfo is written alongside video
4.) No -poster.jpg is extracted from the file
5.) Chapter image extraction fails
As a follow up, I experimented with different library settings (Mixed, Home, Movies):
"Movies" libraries operate as intended (images + nfo written)
For other types (a generic video like "Steven.mp4" with a few tags in a mixed or home video libary) doesn't get its tags read, or its thumbnail extracted, or an nfo written.
In a "Movies" library with loose files and nothing but Nfo writing and Screen Grabber checked, no nfo or images.
Previous behavior of similar files:
When scanned, their MP4 tags were read and appeared in the Nfo files that were created upon scanning. Images were extracted as posters. Thumbnail extraction worked.
