André Timmermans, author of DigitalCD, has released an update to his tracker music playing module TimPlayer. The new version adds support for several new tracker file formats, as well as including many other changes and fixes.

Meanwhile, RISC OS Open have secured permission to release the SharedSound module. This should improve the situation regarding sound support for owners of modern ARMv7 powered RISC OS systems.

 

Tech-centric news site The Register have an article up that gives a brief overview of Acorn, the BeagleBoard, and the fact that RISC OS runs on it. Not exactly new news to the average RISC OS user, but the article is still worth a look just for to see the comments from old hands such as Eddie Edwards, Heyrick, and Hugo Tyson, and some extra trivia tidbits linked to by commenter jlocke.
 
Now, who wants to be the first to enlighten Peter Gathercole that adding (working) pre-emptive multitasking to RISC OS is in no way "trivial"?
 

Watching video on RISC OS isn't very easy. We've run an article here on how you can download and convert YouTube videos into a format RISC OS can understand. Though it's very clever, and the tools involved are actively developed, it's not as simple as clicking 'Play' in a browser window.
 
Improving this situation has been hampered up until now for two main reasons:

• RISC OS hardware has been too slow to play back video at an acceptable rate;
• RISC OS software hasn't supported popular codecs (formats), some of which are proprietary and expensive to license.

 
The first of these is already well on the way to being fixed. The Beagleboard is modestly powered in comparison to the average desktop PC, but it's perfectly capable of playing video at a decent rate. The diminutive boards have been shown running 720p video (a high-definition format) while running a Linux distribution - have a look here to see this in action.
 
The RISC OS port can't quite match that yet. All that might be about to change, though, due to the development of something called Theorarm. This is a library of routines to enable the playing of videos in the Ogg Theora format on ARM-based machines. Ogg Theora is a relatively new format, but it has some interesting features. Perhaps most importantly, it's entirely open source, so videos encoded using the technology can be played back by any suitably-written software. Moreover, Theora is one of the contenders for the [video] tag in the new HTML5 specification. That means that it may become a significant rival to the more common MPEG and Flash videos on the web.
 
Theorarm is interesting, as it's been optimised for newer ARM chips using hand-written assembly code. This makes it very fast. The developer, Robin Watts (of Warm Silence Software fame) has done some development work on the Beagleboard, with promising results: "With post processing disabled, I can play a PAL DVD sized film (720x576x25fps, 48kHz stereo audio track) in realtime with software YUV2RGB. The limited profiling I've done, along with some back-of-an-envelope maths suggests that we should just about be able to do 720p films if the YUV2RGB process is done by hardware." That means, in English, that DVD-quality film can be played back on a Beagleboard with decent audio too. If some of the complex conversions from YUV colour format to RGB could be carried out in hardware, then higher definition films could be played.
 
This is pretty exciting stuff for Beagleboard owners. If Theorarm is ported to RISC OS (and there's no reason, other than developer time and effort, why it couldn't be), then we'd have the basis of a fast, native video playback system. Some issues would require addressing, of course, since RISC OS can't handle the Beagleboard's YUV facility - see here for Jeffrey Lee's proposals to fix this - but these are all surmountable.
 
If anyone is interested in getting involved, then the ROOL project is the place to start. In particular, the proposals for working on the GraphicsV vector need attention from developers with the right level of experience, and the draft API on the ROOL site could do with some more exposure.
 
A few years ago, RISC OS lacked fast hardware, a half-capable browser and a media player capable of showing popular streaming video formats. The first two are being actively addressed - what are the chances that the last one will be as well?
 

Ever since Jeffrey Lee began work on porting RISC OS to developer boards such as the BeagleBoard and IGEPv2 there's been interest in putting a case around them to make them into proper computers. Both ports are still firmly in progress, so a finished-off A9-style computer isn't likely to appear for some time. That hasn't stopped some hobbyists having a go at making their own. This one looks particularly impressive:
 

 
There are more pics and description here on the ROOL forums. The nutBOX comes hot on the heels of Dave Thomas's lego housing for his IGEPv2 here, first reported on riscos.info.
 
There's still some way to go before the RISC OS OMAP port is stable enough to drive a general purpose computer suitable for everyday use, but in the meantime, plenty of people are having fun with what already exists...
 

One of the frustrating things about being a RISC OS user, is its lack of support for commonly-used video formats, other than its own dedicated Replay system.
 
A few attempts have been made to remedy this situation, but, until recently, they have come to nothing.
 
In the mid-1990s, Innovative Media Solutions produced a range of Acorn readers for PC-format, educational CDs, such as Microsoft Dinosaurs and Dorling Kindersley's The Way Things Work. These readers included dedicated versions of ARMovie, which could convert the CD’s AVI files to Replay format on the fly.
 
Unfortunately, the work that IMS had done, did not result in the release of a souped-up version of Replay, which could play all Quicktime and AVI movies, despite the fact that RISCOS Ltd seem to have done some work in this area about five years ago.
 
But now, with the release of the open-source applications, Murnong and FFMpeg, by Chris Martin, things have started to take a turn for the better.
 
Although RISC OS still does not have a proper media player, which can play all the common video formats, we do now have the next best thing - an application that can capture a YouTube video stream as it arrives, and convert it to an MPEG file, which can be played using KinoAmp.
 
 

After hearing the news that videos from the recent RISC OS London Show are now available online, I decided to take a look at what RISCOS Ltd had to say in their presentation. The results I found to be quite shocking...
 
Disclaimer: Although I've obviously been doing a lot of work for RISC OS Open recently, I am not a member of ROOL, nor am I speaking on behalf of ROOL (or The Icon Bar). The opinions expressed below are mine and mine alone, and any likeness or resemblence to any other person's opinions is entirely coincidental.
 
 

For several years now, the need to get RISC OS running on faster hardware has been pressing. It may not be the platform's worst headache (lack of developers is surely the biggest problem), but the Iyonix and A9 hardware are now well past their prime. Even on release they weren't blisteringly quick, and cheap PCs have now left them far, far behind. Things that are taken for granted on a Windows or Mac OS machine, such as watching video, are simply impossible on current generation RISC OS hardware.
 
 

RISC OS users may be left without updates to NetSurf unless a suitable programmer can be found to continue development.
 
Although the RISC OS version of the web browser has more features than other platforms it has not been actively maintained for over two and a half years. Many of the features which were specific to the RISC OS version are now being moved to the multi-platform core which is being actively worked on.
 
NetSurf contributor Michael Drake told The Icon Bar that it was "a big shame ... no-one really wants to drop RISC OS support but there's no-one to actually keep it working at the moment." The team has made an urgent appeal for a C developer with knowledge of the WIMP to get involved.
 
The open source project began in 2002 and the first major release was in 2007. NetSurf was voted "Best non-commercial software" four times in Drobe's annual RISC OS awards. It has been ported to Linux, BeOS and AmigaOS, and the team are participating in Google's Summer of Code.
