[wplug-board] [wplug] DLNA transcoding

[Justin Smith]

I’m not sure whether I’m misunderstanding what you said or you’re 
misunderstanding what I said, but I don’t think we’re on the same page 
here.

I currently use MiniDLNA to serve up files over UPnP/DLNA to my Raspberry 
Pi. If my Pi doesn’t support a video’s format, I have to manually re-encode 
it into a compatible format, which takes time and wastes disk space with 
multiple versions of the same file.

I know that certain DLNA servers like PS3MediaServer support transcoding 
on the fly so that X file fomat gets streamed as Y file format instead. No 
new files are generated, and you can keep the original files in their original 
condition. That’s what I’m looking for.

What I /don’t/ know is if any of these DLNA servers support transcoding on-
the-fly for video profiles as opposed to file formats. Converting video files 
from format foo to H264 is a common use case, but converting from one 
type of H264 to another seems to be far less common. The documentation 
is confusing.
