On ProAction pumps life into AudioWorks:

Dear Monty I bought AudioWorks at Wakefield and was very disappointed with it becasue it will only load 90 seconds of audio at CD quality, even when you've got a huge amount of RAM. Save yourself the £15 and download SampleEd from the Really Good SOftware website. Jon Robinson (Leeds)

Hi Rob When you say that the DSP code is available for a fee, does that mean that people who want to build devices around this motherboard have to pay to unlock it on every machine sold?

Also how much are the development tools if the Beagle RISC OS people want to buy a copy?

Dear Monty

I had a go at using the freely available version of CineWorks with some JPEGs over the bank holiday, to see if you could make an MPEG out of them.

I managed to lay the JPEGs out on the time line, once I'd converted them to sprites, use a WAV file as a sound track, and save it as a playable Replay movie.

However, there is only one Replay to MPEG convertor available, called MakeMPEG, and when I tried it with the Replay file, not only was it very slow, but it also generated a floating point error, leaving an unplayable MPEG file.

I don't have the later MPEG- capable version of CineWorks, so I don't know whether that would fare any better.

If anybody reading this has it, perhaps they could have a go and tell us what happens.

However, once a RISC OS 5 version of the BeagleBoard becomes available, we will have a RISC OS system with a 600 MHz main processor and a dedicated AV processor, specifically designed for fast MPEG and MP3 playback.

At the Wakefield Show the RISC OS Open people were saying that one of the first positive benefits of this, was that we were likely to see the first real-time DVD player on RISC OS.

For the first time we will have hardware that makes digital video on RISC OS a doable proposition.

What we really need is either for the code for the latest version of CineWorks to be made open source, or, even better, for CJE to take over development and support of the product, so that it can be made 32 bit and also be properly main- tained and supported.

On DigitalCD developer seeks beta testers for version 3.0:

This is slightly off topic, but one improvement I'd like to suggest to KinoAmp, if you're reading Andre, is a proper volume control with slider, like they have on Windows (spit!), rather than just an on/off button.

Many MPEGs, in their virgin state, are either too loud or too quiet.

Many thanks for developing this app, by the way. I do a lot of work with FFMpeg, extracting MPEGs from FLVs and VOBs from my DVD recorder, and without your sterling efforts, I wouldn't have anything to play them on.

Hi Monty

I’m pretty sure that Henrik Pedersen was the original author of CineWorks, so it might be worth contacting him, to see if he will let you have a copy of the 1998, MPEG- capable version of his program.

The problem with digital video on RISC OS was that, before the 1998 version, you needed a £500 digitiser card to get your own footage into Replay format, and the quality was severely limited by the hard drive speed on your RiscPC.

Now, however, with FFMpeg’s ability to convert many more video formats to MPEG, which can be played with KinoAmp, the MPEG version of CineWorks should be much more useful than it ever has been, if anybodycan rescue it, especially if some brave soul volunteers to 32 bit it !!!!!!!

See if you can get in touch with Henrik, and let us know how you get on.
