New RadeonHD 2.4 drivers Digital Composite Video Support
A-EON Technology Ltd is pleased to announce the forthcoming release of new and updated RadeonHD drivers for AmigaOS 4.
A-EON Technology have once again commissioned Amiga graphics developer, Hans de Ruiter, to update the existing RadeonHD V1.0 drivers to add support for the new range of RadeonHD graphics cards in the R5, R7 and R9 series. Existing registered owners of the RadeonHD v1.0 drivers can update to v1.2 free of charge on AMIStore or through the A-EON secure download server.
New RadeonHD V2 driver In our ongoing and continued commitment to the AmigaONE X1000 platform, we also commissioned Hans to deliver hardware accelerated video playback using the RadeonHD graphics card’s own GPU. The delivers full screen 1080p video playback for AmigaOS 4 using RadeonHD graphics cards for the X1000 and compatible next generation AmigaOS systems. In addition we commissioned Hans to implement DMA support for the X1000 which unlocks the raw graphic power of the RadeonHD cards. The grpahics DMA work has additionally benefited other compatible AmigaOS plaforms.
The main features of the V2 driver are:
● 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 & 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 RadeonHD V1.2 & V2 drivers reaffirm our ongoing commitment to support the AmigaONE X1000 and our future hardware systems.

It also states in the press release that AmigaOS 4.1 FE is a perquisite of the latest HD Drivers.
The combination of the two is required for the video playback to work. The YUV bitmap support is needed before you can composite it, and there is optimised DMA graphics memory transfers in gfx.lib that add yet more speed.
amigakit wrote @AmigaSteve The new version 2.4 driver is compatible with the 4000 series too All customers that paid for the RadeonHD v1.0 driver from A-EON will qualify for a special upgrade price of the 2.4 driver, so they dont need to pay full price.

1) Will I be able to play 1080p videos on AmigaX1000 at full speed now? I have SSD disk with videos I am trying to play.
Yes Hans was able to play video with 50% CPU time remaining on his X1000. I don't know what video card he used.

2) The same question about Sam460ex? Will SAM be able to play HD vids and at what speed? :)
With the right video card the Sam460 should be able to play 1080p at full speed to but it is probably better to wait and see what results people get.

3) And finally - will I be playing Youtube finally play smoothly?
There is already a discussion on updating Odyssey to support the composited video feature. Until an updated version appears there won't be any difference.

Careful there. That was with a 1080p DIVX movie. While 50% CPU usage for that video was better than I was expecting, there will be some videos that are simply too much for a single CPU core to decode. It depends on both the codec and the settings (e.g., the computation power required for H.264 varies greatly depending on the profile and settings used when encoding).
I'm not sure if the Sam460 will be able to play 1080p. The decoding is still done by the CPU, and the Sam460's CPU is on the weak side (and without altivec). Plus, its 4x PCIe bus can't copy frames to the graphics card as quickly as the A1-X1000's 16x bus can. The new composited video feature will definitely help, but it's best to wait and see what the Sam460 manages to do.

AROS is a branch on the Classic tree, so I understand that you feel strongly in favour of that over AOS. Why not use this and other forums to present/update people about your development in a positive manner?
Where did you get AROS is a branch of the classic tree? It's far from it. Technically in many ways it's more advanced than aos4.
Gallium AROS has had it for years. 64 bit already exists. smp is being worked on and anyone can test it. It has much better driver support. iirc there has even been some usb 3.0 work done. It's far from perfect but it is also far from classic.
