RadeonHD driver: Version 1.2 and 2.4 announced / Sam460cr installation solution
Under the title link A-EON Technology has announced updates of his RadeonHD graphic board driver for AmigaOS 4. Additional to the free update to version 1.2 for owners of version 1.0 of the driver released in April, there will be also the commercial version 2.4.
Version 1.2 of the the driver developed by Hans de Ruiter supports further RadeonHD boards of the R5,
R7 and R9 serie (compatibility list). With version 2.4 the hardware accelerated video output in 1080p will be possible as announced at the AmiWest. DMA-support for RadeonHD boards will be available as well.
Features of the V2 driver:
- YUV bitmaps with CompositeTags(). YUV420p bitmaps are 37.5% the size of 32-bit ARGB bitmaps so there's less data to copy to the graphics card
- While overlay is restricted to 1-2 surfaces and does not respect transparency, Composite Video can render an unlimited number of surfaces and can perform alpha blending instead of chroma keying which can be used for advanced video effects
- Videos can be Rotated, warped and even projected into another video
- Alpha blending/compositing can be used for cross-fade between video files and other effects
- Full 1080p Video playback with supported video files
- Support for the latest generation of AMD Radeon Rx graphics cards from the R5, R7 and R9 series
The full RadeonHD driver ordered by A-EON Technology will be not part of the announced Final Edition of AmigaOS 4.1. In order to make the driver available to future owners of a Sam460cr without having to use an additional and old graphic board, a minimal version will be included. According to AmigaKit and confirmed by Hans de Ruiter, A-EON Technology, ACube Systems and Hyperion are working on an adequate solution.
