The RISC OS User Group of London (ROUGOL) will be meeting up again on Monday, 15th June, and the guest speaker will be Phil Pemberton, who will be talking about Replay.
Replay was a video compression and playback system available for RISC OS computers back in the mid-1990s. Anyone who bought a RiscPC at the time will have found the playback software and a small number of ‘ARMovie’ video files on their hard drives to show it off.
Phil Pemberton has been looking at the sources for the system and – when not breaking out in a cold sweat after looking at Sophie Wilson’s highly optimised ARM code – he has taken on the challenge of trying to get it working again. This isn’t just limited to the playback software – the front end and code to decompress ARMovie files – but also the compressors, which means he has been able to create the first new files in that format in many years.
Phil will talk the group through what he has done and found, demonstrate the different compression techniques utilised by the system, and some of the movie files created with it.
As usual, the meeting will be a hybrid one, with some people attending in person and others attending online. If you can make it to the venue, your destination is:
The Duke of Sussex
(Upstairs in the Chichester or Petworth Room)
23 Baylis Road,
London,
SE1 7AY.
There are directions to the venue on the ROUGOL website, and you can expect to find members lurking from around 6:30pm. The meeting proper will commence from around 7:45pm.
If you can’t make it to the pub, but can make it to your own desk, you can use Zoom if you have a device that can run the software. You’ll also need the log-in credentials, which remain the same as previous meetings – so if you’ve already joined one you should have them, but if not you can get them by contacting ROUGOL. The Zoom meeting should be open for people to join from around 7:30pm.
