There are millions of DLNA-enabled devices out there and they all support different video, music and photo formats. Some support more, some support less, but I think it's safe to say that no single device supports all existing format variations.
This is where KooRaRoo Media's powerful (and smart!) transcoding engine comes in. Transcoding simply means converting.
KooRaRoo Media can read pretty much any existing format you can throw at it (see a full list of supported formats on this page: http://kooraroo.com/features.php) and after that it's smart enough to recognize your device and check what formats it supports. This is done through the supplied device definitions (device profiles) that are actively maintained to make sure they match the latest firmware changes.
Music and photo conversion is relatively easy. The tricky bit is video conversion, when done properly. KooRaRoo will try to remux the video if at all possible. Remuxing means simply copying a stream. This allows for a very quick conversion that doesn't require much CPU power and is very quick.
A very powerful and useful feature of KooRaRoo is audio stream language matching to your preference. Let's say your first language is English, but you also understand Russian and you have a video file with multiple audio streams. Once you set your audio language preference in KooRaRoo, it'll pick and use audio streams from the file that match the priority of your languages. It sounds complicated, but it works behind the scenes and once you tried it, you'll be surprised how you ever lived without this :)
In KooRaRoo you also have full power to do manual conversions which allow you to tweak parameters and choose video/audio streams. You are in full control!
This is just one of the many great features that KooRaRoo has.
So, give KooRaRoo Media a try and see what the new DLNA media organizing and streaming software is all about.
