MARIVP

Python tool to generate preview files for the marine-data viewer (photos, videos and thumbnails):

Hotfolder refers to a folder in which media files are temporarily stored, automatically processed (i.e., encoded) and returned - all within a defined structure. FFmpeg is used to encode the media files, the encoding parameters are passed via a configuration file. Within the hotfolder different encoding profiles can be defined, even while the script is running profiles can be created and used immediately.
