Automatic transcoding of images
Most of our photos here are stored in the camera's "raw" format. Some people may prefer lossless TIFF, TGA, or PNG to the ubiquitous JPEG.
Worse! None of the Sony equipment (neither the TVs, nor the their standalone picture-frames) can show the JPEG-variant known as "progressive" -- where the image is shown layer-by-layer with more and more detail, rather than row-by-row. The progressive JPEGs are nicer (in my opinion) for the web, and they are also usually smaller -- jpegtran can convert from progressive to regular JPEG without recomputing (and thus without any additional quality loss).
Would be nice, if Serviio could transcode images into what's acceptable to the device (perhaps even downsizing them to the TV's maximum resolution, if necessary).
Java includes the libjpeg and thus should support all JPEG-manipulations/transcoding. For the raw formats of most cameras, one can use ufraw-batch just as ffmpeg is used for videos.

FreeBSD port of Serviio is now in the tree. Please, try using it and share your experience.
