v1.360+: DRM extension now available
@rohit Well, there is not much to say at this point. I have been working on re-packaging the open source Dream code into a Kiwi extension for about 4 weeks now. Much as I have done for other open source work (e.g. the Kiwi SSTV and CW decoders).
When might it be available? I would say weeks to months. The work has been very, very difficult for a number of reasons. And I don't fully understand the legal issues about the codec and how exactly I have to handle its installation. This is a major limitation and annoyance with Dream and I want to completely automate a solution (part of the Kiwi philosophy).
The biggest surprise is that it works on a stock Kiwi using the Beaglebone Green/Black. Although right now only with severe limitations. Essentially nothing else of significance can be happening on the Kiwi except for GPS. The waterfall nearly comes to a halt due to the lack of cpu cycles. So for now it is a single-user solution.
BUT this is better than nothing. I initially expected it would only work using the Beaglebone-AI which is not available as a standard Kiwi product (you have to put one together yourself). But note that no effort has been put into optimization of the code yet. There is a lot that can be done. So I have hope it will perform better on the BBG/B in the future.
You are correct that All India Radio on MW (e.g. Delhi 828, 1368) uses the xHE_AAC codec and there is currently no support in Dream for xHE even though the codec I use in Dream (fdk-aac) does support it. Julian Cable of Dream development said a year ago he's working on it. But so far nothing has happened.
Note that the patent situation is not unique to xHE_AAC and Fraunhofer (fdk-aac developer) as your post implies. It is a general issue with all AAC codecs and intellectual property. Fraunhofer has made the copyright of their codec somewhat open (subject to limitations) and this is why it has recent support in Dream. But this does not change the patent situation including Fraunhofer's additional patent claims. -
