Adding video support to the thumbnailer sub project.

• find one or more library that can do this fast by experimenting
• implement the library into thumbnailer

Hello @AngeloFrangione :)
I have been planning to write a photo library management program that was a C library with no GUI embedded in it, and was searching across Github to see if a similar project existed. I found this, and would like very much to contribute as I have a personal interest in seeing it completed and production-usable with many features.
I would wish to get into contact with you so as to be able what exactly needs to be done, how the code is organized, possible ways to redesign the code, etc. Could we chat on Element (Matrix)? My ID is @adbeveridge:matrix.org

The exif fields are in the database, but nothing is populated during import time.
ressources:

• https://libexif.github.io/api/exif-loader_8h.html#a2b96cbffaf0f92340a960f887026eced

todo:

• create the libexif wrapper
• implement the wrapper functions at import time

Using meson cross files and mingw

Some resources:

• https://thiblahute.github.io/jpakkane.github.io/Cross-compilation.html
• https://mesonbuild.com/Cross-compilation.html

issues:

• thumbnailer only works with elevated command prompt.
• sqlite3_last_insert_rowid returns 0 -> the function was called to lately
• make tests work with wine

functionalities:

• make a windows build in travisCI requires: make tests work with wine
• script that copy the dll files from the subprojects to the build folder

Add PNG support to the thumbnailer sub project

• find a library that can do this fast by experimenting
• implement the library into thumbnailer

functions to realize:

manage the folders "virtually" in the database first:

• database_create
• database_delete
• database_rename
• database_put

manage the folders physically, with the actual folders:

• folder_create
• folder_delete
• folder_rename
• folder_put

testing and documentation:

• implement tests
• update doc

This function currently does one transaction per picture. It should do a single transaction this would significantly speed up the import process.

OSPL should print useful debugging info only when DEBUG is enabled

• find a clever way to print only in debug mode -> new function debug_printf()
• add debug info into thumbnailer
• add debug info into ospl
• change the existing print in DEBUG only

Ideas to realize this:

• adding a live_photo table with the photo id, and the associated video id
• adding a live_photo column in photos and video, so it can be found faster when showed.
• during import, if a video is present, check if the filename is the same as any imported photo in the same folder.
• if the live_photo column is set to true in the video table, it can be ignored by the client, so it isn't showed aside the picture
