Hope you wiped up properly .

Well, the floor is pretty clean

And indeed hardware accelerated video playback is a nice achievement and pretty handy. But game changing... rather not.

User do not use any OS because it is "better"

They use it because of available and (in best case) exclusive software. And developers support a platform not because it is "better" but because of the users (and thus potential buyers). There is the big advantage of vampire (together with UAE)

The video playback is actually more powerful than demonstrated in the video.
Think up to Ultrawide 1600 res. Under 10% CPU usage for whatever multiple video combinations that work with currently available GPU ram (Sam460ex test machine).

Eventually being able to offload video decoding,encoding ,3D and 2D Graphics (Skia like) to the GPU would be Game changing for computers using Powerpc processors .

I said it's a nice feature and pretty handy an cpu weak computers, but this is not game changing, It's just catching up in one standard discipline.
Not bad though, really not.

Personally, assuming mainstream video codecs are in fact supported which Spectre660 has not confirmed, I find it to be a million times more useful than being able to run smartphone games on desktop hardware.

That said, for better or for worse, media consumption on desktop computers has moved towards web browsers. If a 50 EUR tablet can smoothly play videos on any HTML5-compliant web page but your 1000 EUR desktop computer struggles with 360P and you are expected to use semi-clunky external tools for smooth high-resolution playback that only support one or two video portals, then that would be less "game changing" and more "not even really in the game" territory.

Of course, as usual, none of this information is provided and people are expected to merely guess and speculate after reading 3,000 word blog posts and watching minutes of video footage.

If you expect people to invest 700+ EUR on compatible mainboards and graphics cards, being able to play HD video is the bare minimum bar in 2020, I'd say. Not "game changing" but certainly an accomplishment.

That said, regardless of how smooth the playback might be, I myself could not stand watching videos with messed up color palettes so black looks grey...

@ASiegel

does this apply to what you are discussing?

@ASiegel

No issue with color palettes here .

Quote:

Just a thought since you are trying to report what can be achieved here...

Most people would simply ask if they can play H/D or HiDef in sync and without frameskip using a high stress codec, which would be expected from almost any source these days.

PPC MPlayer is not getting bugs fixed. In fact the bug report was closed without being addressed for what is showing up in your Video and Audio codecs output.

It might be helpful to mention that it's not "462H", but "H264" for video codec, and it's not "A4PM" but "MP4A" for audio codec.

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 .

@ Spectre660

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...

Quote:
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 :-)

Quote:

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.
