Cino DVD player released for freePublished: 28th Dec 2006, 20:51:22 | Permalink | Printable
Todo: Find faster hardwareA free version of the RISC OS DVD player Cino has been published online. Author Adrian Lees, who also developed Aemulor and Geminus, uploaded a copy of the software to his personal website after it spent months gathering dust on his hard disc. He said it was no longer possible to continue developing the software commercially, and that his DVD player needed a processor more efficient that the Iyonix's XScale.
Adrian, who now works for a broadband electronics company, said: "My RISC OS stuff kinda fell by the wayside when it was no longer my full-time business. Consider this my gift, maybe it'll help in some small way, but commercial development [of Cino] sure as hell ain't possible. I don't see it going commercial on the Iyonix; it's too much effort for too little return."
Cino on the Castle Iyonix can manage around 12 frames per second, or roughly half the speed required for full smooth playback. Adrian said the main limiting factor was the Iyonix's 600MHz ARM-compatible IOP321 processor and its crippled memory bus. Although Adrian isn't holding his breath for a new 'Iyonix 2' motherboard from Castle, he said Cino would be fast enough on processors more efficient at accessing memory.
He said: "It's not RISC OS that's holding back Cino, it's the IOP321 XScale. We're stuck in the past with regards to desktop processor performance. If Iyonix Ltd [aka Castle] release a new motherboard with a CPU that has low enough memory latency to make it a good DVD player, I'll forfeit the revenue. If Cino could be compiled for any other desktop CPU, would certainly be fast enough."
The download includes DVD driver and filesystem modules, and a DeCSS module to play standard copy-protected discs.
The Cino project was first announced in late 2003, although development was paused in August this year. Publisher Neil Spellings of spellings.net said he believed people would prefer to buy cheap standalone DVD players than pay "the huge premium that a commercial DVD player for RISC OS would now require to cover development costs."
