Not quite. When you are bragging about being able to decode videos that exceed 1080P resolutions this only has any real-world relevance if you support HEVC or VP9 codecs.

For example, YouTube does not stream 4K or 1440P videos in H264... (or the older less demanding MPEG-2, for that matter).

Thanks for that.
If I had corrected them in the output though some would probably have called me a Doctor of sorts .

For Sam460 owners quite a nice thing. And I actually think it's fine for future Tabor owners, too as it may compensate a bit for the stupid cpu choice. Offloading as much as possible to the gpu is on a non smp low cpu power system always a good thing (on other systems, too, but not as necessary). And if you doomed to weak cpus probably the only way forward...

I will have to take your word for it. The promotional video shared via YouTube clearly looks to have wrong colors (see the trailer part).

@ASiegel

I used to run the test videos also on a Windows machine with the Sam460ex and Windows monitors basically side by side. Did not spot any palette issues with the Sam460ex.

From developer pov gdb saves too much time to resign from it just beacuse some here still have mental problems with ppc.

gdb is something that I really miss on MOS. Custom solutions in MOS are nice but gdb is better.

Doing 3D without 3D hardware on vampire as it was done on pc about 1994 does not make any sense.

It is waste of work and time for nothing.

@ASiegel

In stages .
For HEVC and VP9 we will have to see what the future holds .
Next challenge to get through is accessing enough video ram for full 4k playback.

If both Emotion (as shown in the video) and MPlayer exhibit this same issue, it seems to be with FFmpeg, which both are based on.

I used Mplayer to get the detailed video info. Emotion to actually play the videos.

Excuse my ignorance, but is this because Emotion does not have option for verbose text output?
Also, if you are getting the text info from MPlayer, why are you not -playing- the file with MPlayer?

Ah okay. I misunderstood then.

The file info with Emotion is displayed by selecting the "about" Menu Item.
Which gives Progam version and the decoding option available.
Both of these have not been made available to the public yet.

I guess because MPlayer doesn't support GPU-accelerated video decoding (yet), which is what this whole exercise is about :-)

Good one.
With at least 7 different developers involved at some point with MPlayer and the continued discussions on AW about performance based on different versions optimized for different h/w....this is not always simple to grasp. heh.

No "Amiga ppc" does not. What you are pushing advocacy for here is not "Amiga".

We Amiga users use ppc Amigas because they are better Amigas than these produced by Commodore after ECS.
Some idiots in Amiga community waste time on attacks on ppc because they think that if they attack enough long there will be switch to x86.
This is not going to happen as long as Amiga solutions on x86 are shit compared to win/osx/lnx.
So dear redrumloa stop this crap and start hard work on AROS or MOS on x86.

AmigaOnes are in no way CBM/Escom continuation, and all except SAM440 had quirks and shortcomings not supported fully in OS4, or board was crippled in way (single SATA, slower mem. etc.).
XE - bad mem and USB
SAM 440 - only fully supported board, espec. M9 version
SAM460 - unsupported DMA onboard SATA, even today
x1000 - buggy CFE, no support for LAN, other core, 2GB+ PCI-E wired to Xena with no use,
slower PCI slots, BETA OS TO PREPAID OS 4.2
x5000 - no support for LAN, other core, 2GB+, PCI-E wired to Xena, less expandable then x1000
STILL BETA OS NO FULL DRV, only good thing is MOS support (as with SAM460ex)
x5000/040 - exists but its hidden, too expensive and not so fast by Linux tests
Tabor - in Linux existance for few years
STILL BETA OS NO FULL DRV

None of great PPC board has out of box PPC Linux support in major distros LIKE ALL OTHER PPC32 and PPC64 computers do have!

I mean, can you do a proper job, once in a while.

Do a single CPU, OS4 max hw design or improve OS to hardware. Mac PPCs are great machines compared to this jungle

I have in the past a1200 it has many times too slow graphics - famous lack of chunky pixels.
My various ppc Amigas even if not perfect deserve more on Amiga name than amiga 1200.
At least graphics is as fast as on pc.
Get lost dear vox.

And of course most of my ppc Amigas works on Amiga OS that is direct continuation of it in my 1200.

> x1000 - [...] PCI-E wired to Xena

While Xorro uses a PCIe x1 connector, it is not wired to the PA6T's PCIe subsystem.

> x5000 - no support for LAN, [...] PCI-E wired to Xena

Isn't Bigfoot's driver available through A-Eon by now?
And while Xorro uses a PCIe x1 connector, it is not wired to the P5's PCIe subsystem.

> x5000/040 - exists but its hidden

X5000/40 was shown at Amiga34 in Neuss :-)

> None of great PPC board has out of box PPC Linux support in

Official PPC32 support (including G3/G4 Macs) has vanished from almost all Linux distros and certainly from all major ones. Big-endian PPC64 (including G5 Macs) is a small bit better off.

> Do a single CPU, OS4 max hw design [...]

X1000 and X5000 are single-CPU ;-) PA6T was never available in single-core version, and using P5010 instead of P5020 would have saved some small dollars only (compared to overall board price). Bad decision was using a common board for P5020 and P5040, which are neither fully pin-compatible nor fully SerDes config compatible, resulting in crippling of P5020.

As usual thanks for tech correction, but it barely changes hash reality of going
from bad to worse.

While G4 and G5 support was dropped recently from major distros, Deb PPC supports it fully even now and many a bit older distros can be installed.

Au contrare, except from only paid x1000 Ubuntu in the world, there is no other distro that can CD Boot to x1000 and install without inserting kernel during install or DDing and inserting kernel via kernel files on slow SD card.

And FAT16 SD card of 4GB corrupts itself (CFE bug?), Linux kernel cant boot from SFS, FFS,
EXT2, EXT3 even manual claims it can. Or amigaboot.of from EXT2, EXT3, thus additional hidden FFS partition ... Utter mess.

Actually, the current Debian PPC status is as follows:
PPC32 (G4): last supported release was Debian 8, since then maintained as community port
PPC64 big-endian (G5): was never a supported release arch, maintained as community port
PPC64 little-endian (POWER8+): supported release arch since Debian 8
PPC-SPE (e500v2): was never a supported release arch, maintained as community port

It is now.

Interesting read:
"In 2014, A-EON Technology Ltd commissioned Varisys Ltd to design and produce the Tabor motherboard. A small batch of fifty was produced and distributed in a closed beta tester/developer programme. Our designers, Varisys, were subsequently acquired by Ultra Electronics and, five years on, several minor components used in the build process are no longer available from suppliers, so changes to the motherboard design became necessary. In 2018, A-EON Technology Ltd approached and entered into negotiations with Ultra Electronics to exclusively acquire the full design data. The process and delivery of design data was completed eleven months later. During 2019, A-EON approached members of the original Varisys team to help evolve the Tabor project. The A-EON A1222 Plus builds upon the older Tabor design with sections of the motherboard updated to address obsolescence of components. To ensure there are no hardware surprises at least five motherboards are being manufactured to prove the updated A1222 Plus design changes. Following the successful proof of design, the Early Adopter batch will be manufactured and it is currently estimated that delivery will commence in the second quarter of 2020."

Strong opinion piece on Tabor:

"My disenchantment with the current crop of PowerPC-based Amigas [...] is well-known. At their various asking prices you got embedded-class CPUs at mid-high desktop level prices with performance less than a generation-old Power Mac. (Many used and easily available models of which [...] can run MorphOS for considerably less cash out of pocket.) A-EON's AmigaOne X5000 in particular attracts my ire for actually running a CPU that doesn't have AltiVec to replace the X1000, which did. Part of this problem was the loss of availability of the PA6T-1682M CPU [...], but there were plenty better choices than the NXP P5020 which wasn't ever really intended for this application. [...] the original A1222 "Tabor" board [...] was specced [...] with [...] most controversially another grossly underpowered embedded core, a QorIQ P1022 at 1.2GHz. Based on the 32-bit e500v2 microarchitecture, it not only also lacks AltiVec but even a conventional FPU, something that for many years was not only standard on PowerPC CPUs but considered one of its particular strengths. As an embedded CPU, this was forgivable. As an embedded CPU in a modern general-purpose computing environment, however, this was unconscionable. Even by Amiga standards this was an odd choice and one with potential impacts for compatibility, and one a G5 or high-end Power Mac G4 would mop the floor with. [...] various other components needed updating. Strangely, the CPU was not among them. [...] if A-EON chose this CPU deliberately as an attempt to make the price of the system lower, they chose wrong. [...] Amiga has a long history in computing consciousness and most computer nerds would at least recognize the brand. Similarly, people still remember Power Macs, and [...] there's a rather pernicious and commonly-held belief that Apple's migration to Intel somehow "proved" the inferiority of Power ISA. Today, along comes yet another underwhelming PowerPC-based Amiga to confirm their preconceived notions: because it's Amiga, it sticks in people's minds, and because it confirms their own beliefs about PowerPC, it reinforces their unjustified biases. Regardless of the fact that POWER9 systems [...] outpace ARM and RISC-V and compete with even high-end x86_64 offerings, the presence of Tabor and X5000 et al simply gives the resolutely underinformed yet another stick to beat Power desktops with. These Amigas suck compared to PCs, they reason, so OpenPOWER must suck too. At the very least modern Amiga systems need to beat these decade-plus-old Power Macs to be even vaguely taken seriously. If they must go embedded then at least an e6500-series processor would do better than anything that they're running, and [...] going with a minimally-redesigned reference design board for a POWER8 or POWER9 in big-endian mode could still free up development resources for such a task that would otherwise be sunk into yet another quixotic product. As it is, these Amiga systems don't do the Amiga community any favours, and from this outsider's view their performance even seems to be going backwards. [...] weaksauce systems like this being sold as desktop machines continues to tar the architecture as underpowered and does nothing to expand the market beyond the shrinking circle of faithfuls. When there exist today at this very moment Power ISA workstations that can be every bit as utilitarian and functional as Intel workstations, the last thing any of our two communities need is yet another Amiga that people don't want."

My 2 cents as to notions I disagree with:
1. The Tabor board design change to replace some obsolete components by more recent ones couldn't have involved a change of the SoC as this would have required a new from-scratch design.
2. There was no better choice than the e5500-based QorIQ P5 series in 2012/2013 when the X5000/Cyrus was conceived. There was neither e6500 nor OpenPOWER back then.
