Okay, the video is fine now; it all depends on how the YouTube video was encoded.
But I still have a problem: the audio cuts out at a certain point.
I've tried different versions of YT.rexx, but it doesn't change anything.
I've changed my screen resolution, disabled everything in WBStartup and in user-startup, and tried with different videos, but the audio cuts out again.
On X1000+RadeonHDv5 VAAPI works fine, but you cannot play H.265 videos here: Southern Island cards itselves have only HD(720p) H.264 decoder and no H.265 decoder - UVD3.1 To utilize full VAAPI you need Polaris card, which has FullHD H.264 and H.265 decoders - UVD6.3
Southern Islands can perfectly decode 1080p streams. There is something Hans nevers manage to find which prevents Southern Islands from decoding correctly 1080p videos (and even some 720p videos whereas CPU usage is still low).
Here are the capabilities of an R7 250 (from AI since I did no want to look out for many sites right now):
Quote:
1. Capabilities of the R7 250
The R7 250 has the UVD (Unified Video Decoder) block, version 4.x.
It can hardware decode Full HD 1920×1080 videos in: * H.264/AVC (common in .mp4, .mkv, Blu-ray) * MPEG-2 * VC-1
When playing back supported 1080p H.264, CPU usage typically drops to just a few percent.
2. Important limitations
No hardware decoding support for HEVC/H.265, VP9, or AV1 on this generation.
If your video is encoded in H.265 (common for recent encodes), decoding will mostly rely on the CPU.
It is optimized for 8-bit H.264; exotic profiles (high profiles, 10-bit, very high bitrates) may also fallback partially to CPU.
What's more, the driver crashes with a grey screen without any reason afters having watcheds one or two videos.
Hans explained he never found why this behaviour was occuring and advised to switch to an RX card.

Short blurb you can put above the lists:
Spectra is a native ReAction GUI with Mesa for V-MPlayer on AmigaOS 4.1. The engine now runs FFmpeg 8.1 with VA-API and a lot of extra playback features. Coming soon to AmigaOs4.1...

Can it woks without mesa too, right ?
Yes — Hollywood is gone. The GUI is plain C + ReAction, the engine is V-MPlayer (FFmpeg 8.1). Mesa GLES is only for the optional visualizer.
Without mesa.library the GUI still plays files, radio, video (VA-API), EQ and the rest. The Viz button just says it needs Mesa.
It’s impressive, and I wanted to do something with the new Mesa. Machines without va.library don’t get MPEG-4 video acceleration either — so yes, this is VA-API and Mesa, and it’s fully working on X1000 / X5000.

Looks very nice! Does it support Altivec if available? Can it?
There will be two engine binaries.
One is built for G4 with AltiVec — CPU SIMD for machines that actually have the vector unit (G4, and X1000). That’s the path that helps software decode and scaling when there is no VA-API.
The other is hard-tuned for X5000 (e5500, no AltiVec). That machine has no AltiVec, so enabling it would just crash. That build stays scalar on the CPU and leans on VA-API for video.
