As I mentioned elsewhere in the forum, I will be releasing information on how we got into the device - you could use that information however you please. There will be sufficient information for the device to execute a bash script and/or launch an executable from a USB device.
What *we* will be doing is providing continuity for the device to be used for the purpose for which it had been originally sold as much as practically possible.
If anyone wants to support the device in any other way, they are completely welcome to do so, including completely repurposing the device or running some off-line mode of their own design and implementation. We do not have a development toolchain for the device, you'll have to obtain that elsewhere.
If anyone is interested in doing more intensive dash development, I would encourage you to track down where Sony has posted the GPL source code for the device for license compliance and download it.
As to the streaming, I'm not sure what to tell you - the processor used in the dash was originally designed for use in TVs and BD players, so it has a DSP which is supposed to effortlessly decode video. However, I don't know enough about the dash's middleware to tell if their implementation of the system takes optimal advantage of that capability.
EDIT: The path to Sony's posting of dash source code is https://products.sel.sony.com/opensourc … dash.shtml
