How to avoid re-encoding video files during uploading? Dev solution need

[gerry76]

hello everyone, I bought the synology Ds218, I need to upload 250gb of photos and videos to Photo Station, I realized that it will take weeks, because without me asking for it a process ffmpeg41 is launched that goes to re-encode the video to a lower resolution, this in addition to taking up more space, slows everything down for me. I would like to avoid this step, and just have one frame of the video as thumbs, in the gallery.
On my own I investigated and tried to figure out how it works, I backed up the postgres db to figure out the folder structure, discovered the @eaDir folder with the thumbs the symlinks and covers and the compressed video, and the /volume1/@appstore/CodecPack/pack/bin/ folder that contains the ffmpeg41 executables etc...

Have you investigated and already have a solution? Can you suggest how to do it if possible?
I'd like to know what process starts and maybe go and change that by preventing it from re-encoding the video and maybe making it copy the same one of very small size all the time, this is because so much when I see Photo Station I have it set to the maximum resolution.

PS: load a video from the web browser, then run this command, you will find the command that is launched with the compression settings, I can't find the script from which it is launched!!!
