Then it will use $c->{mimemap} generated by If it finds nothing it will return document type other.

This file also contains four EP_TRIGGER_MEDIA_INFO trigger functions:

  1. Tests that the uploaded file is of a recognizable MIME type and sets the document object's mime_type field.
  2. If an audio/video file use FFMPEG to extract information to set the document object's media_duration, media_width, media_height, media_video_codec/media_audio_codec, and media_aspect_ratio.
  3. Uses the $c->{mimemap} to set the document object's mime_type field if not already set.
  4. Uses the $c->{guess_doc_type} function to set the document object's mime_type field, if not already set.
