Details
libimageutils.so is the first generation media type detection and Thumbnail generation library.
It is the early FRITZ!OS 5.x. predecessor of libmediautils.so, which was extended for more media types.
Besides detecting the Formats listed below libimageutils can create Thumbnails from JPG, which may also come from
Albumart. First djpeg decompresses the image, then pnmscale resizes it, then cjpeg recompresses it again.
Metadata from JPG files is gathered using rdjpgcom and libexif.so.
Since scaling and (de-)compression are CPU and memory intense an asynchronous job dispatcher queue is implemented.
Formats
libimageutils can detect mp3 and 3 image formats by File-Extensions or MIME-Types and classify them into:
jpeg, mp3, png, tif
File-Extensions
jpe, jpeg, mp3, png, tif, tiff
MIME-Types
image/jpg image/jpeg image/png
Source
The names of source files compiled into an executable often help to understand function blocks (and show gaps in the docs).
fw 5.05 source files:
$ strings /lib/libmediautils.so | grep -e '\.c$' -e '\.cpp$' jpeg_scale.c jpeg_infos.c mp3_albumart.c imageutils_job_queue.c
