Anyone have Athena AND PSP ? Gaming ?

A buddy of mine showed me his PSP. Pretty cool device...Some good gaming...Movie playback rocks.
How does the Athena compare especially with the ATI Graphics chip??
Movies? Best Game? SoCom? ....grin....
Are there games optimized for the ATI chip?

I have both PSP and U1000. You just simply can't compare the two together as PSP's game are specifically and professionally design with a specialize graphic chip/GPU in mind. PSP's game surely leave PPC game in dust. But other application wise, PPC excel, PSP is just too lacking in this area.

ATI GPU
How do we think the ATI GPU compares..performance-wise? How is the movie playback comparison?

Go to the AMD/ATI website and check ouyt the specs and features of the ATI chip.
You will find it is optimised for MP4 (ASP) playback in WM10 (handles it beautifully) it is also responsible for the 3megapixel camera and 2D only acceleration in games.
So...sorry, no 3D games acceleration.
Movieplayback is very good using TCPMP or Coreplayer (can use DVD rips without re-encoding) and looks DVD/High Def quality, but without ATI hardware acceleration I'm afraid.
Once this incompatibility between the ATI hardware and Coreplayer/TCPMP has been resolved, we should be able to experience excellent movie playback at very high bitrates and at true 640x480 resolution. Having said that, this has been an ongoing issue since the HTC Hermes last September and hasn't truly been fixed as a joint venture between ATI & Coreplayer (still in progress, but ATI/AMD are dragging their feet!!).
So there you have it people. For games buy a dedicated gaming device for everything data related and occasional 2D high res gaming, you can do no better than the Athena IMHO.
Compromise? Get the XDA Flame Pocket PC Phone from O2 Asia which has the worlds most powerful gaming GPU for a PPC. The Nvidia 5500 GPU which supports High def video playback and Full 3D support on a hardware level.
But remember, it's no Athena either.

Thanks for that benmorris. Nice to be appreciated.
I've tried dozens of games on the Ameo, but I really only like VGA optimized games so hence 2D games etc. Currently I only have a few installed: Mahjong being my fav.

Touch HD Video Playback Performance Concerns

So here's my story:
I recently bought Samsung Omnia on which I did extensive tests on video playback
with CorePlayer 1.2.5 and TCPMP and with various video formats such as:
H264 Baseline 3 480x272 (originally encoded for playback in iPod Touch)
Various XviD encoded videos with resolutions varying from 640x360 to 720x400
Using DirectDraw as video output in both CorePlayer and TCPMP
the result was awful, dropped frames, awful motion and distorted colors.
However since the Omnia has the fastest CPU I know in WM Device so far,
the Marvell PXA312, 624MHz with IntelXScale acceleration,
the CorePlayer and TCPMP gives this as an option for video output the IntelXScale acceleration.
So when using this setting the video playback of any type of encoding was absolutely beautiful.
Colors were correct, performance was amazing (even in double playback speed) it was in general as smooth as it gets.
For a powerfull (hardware-wise) device such as omnia, I was very disappointed
in the resolution of the screen (240x400 - wqvga) and its size 2.8".
For this kind of device which has literally everything one would expect it
to have same screen size and resolution as the touch hd.
I rushed to buy this device I must admit and so I sold it to a friend after experimenting with it for one week.
The reason that I gave away so fast the Omnia was simply the Blackstone.
Since I am kind of perfectionist as far as it concerns screen resolutions, the touch hd is no match with any other phone/ppc device out there.
So here comes the real concern, how is the performance on video playback on the blackstone?
For a multimedia device like this one would expect that the performance
would be excellent (much like the omnia or even better if it can).
But what concerns me is the Qualcomm cpu at 528Mhz which as far as I can tell
doesn't have IntelXScale acceleration (plz correct me if i'm wrong on this)
So if it uses only DirectDraw and the results are crappy, then this would be such a turn off.
Can this CPU give a smooth video playback performance on a 640x360 XviD avi video
with "Smooth zoom: ON" and "Zoom: Fill Screen" settings on either CorePlayer or TCPMP?
And keep in mind that we are talking about realtime upsizing of the video to 800x480
which IMHO requires quite a lot of cpu power for such device.
Because really I am not willing to spend 700 euro on a multimedia phone
that can't actually perform well on multimedia.
I'd love to hear someone that has it and tested it on that matter.
Thanks for reading!

We really want to know the answer for your question, And I think that we have to wait until we see the phone on the market and get some benchmarks.
Also I think that SE in their xperia phone did what you are asking for ..! In the same beautiful screen resolution 800x480
Thank you,
Mohammed

More like SE said to HTC "We want an awesome phone, but we don't want you to tell us what's in it, and we'll just make Magnus make up stuff as we go, also we suck at marketing."

touch HD has a slower cpu, without xscale acceleration. but it has a dedicated graphics chip, which matters more in video play back. at the resolution you have mentioned, i have full confidence it will do just as well if not better than omnia.

I sure hope so, because I would say I'm not so satisfied with the Touch Diamond performance. Let me explain:
Since this matter is really killing me, I need to be sure it can perform well on video (not extreme stuff, the standard-like video formats we all use).
So I decided to make a test, since i don't own a Touch Diamond (which has the same hardware), I went to a local retail store that had the device on display for ppl to see and experiment with, I installed coreplayer and sent a 40" 608x400 xvid video with ~900kbps bitrate to test it.
CorePlayer was set automatically with video mode QTv and with TytnII Driver mode enabled (which i suppose is the accelerator driver)
I made sure nothing else was running in the background and the results was not so ok. I was playing just ok, I noticed some frame skips and some "lag" in fast motion.
I just hope the Touch HD has revised hardware (if that's possible) and better drivers maybe?
I really would like to hear an answer from someone that has already his hands on the touch hd

but htc is also notorious for not not allowing 3rd party software to use the graphic chip, that is when they do provide drivers for the chip

so are you saying if i were to install a 3rd party video player, when i try to play video, i will see a blank screen? because this player is 3rd party and can't access the graphic chip?? :S

No, i'm saying that coreplayer/TCPMP will only be able to use the default qualcomm chip, its exactly like having a graphic card in your pc with no drivers and no in built support

Thats sux
I hope Touch HD has better driver ... because the hardware is the same.
Quite a downer ...

If that is the case, then I dont understand it. I mean why HTC would go through all this trouble to have an extra graphics chip in their devices when no other than their own app could ever use? So they put a graphic chip with 3d capabilities and video acceleration for just their own apps like touchflo 3d ?
Isn't it just stupid?

Yes, that would be stupid. Fortunately though, there is quite some talk about the HD having an optimized chipset compared to the Diamond, even though this does not include the processor. It is already evident by the many movies that the device performs faster than the diamond even with the same processor, so I doubt you'd have exactly the same performance issues as with the diamond. Though there is only one way to be sure: wait 2 more weeks and everybody will own one.

Coreplayer 1.3.0 is said to have major improvement with QTv rendering on MSM7201A/7200A. This was promised by them on their forum about a month ago.
Head over there and hurry them up! Those guys are reeaaaalllly slow, probably too busy working on Coreplayer for stupid iPhone.

Hi, if I buy the current coreplayer-version from them, do I get a free update when the 1.3.0 will arrive? Or should I wait until it comes out? This would be the most important application for me on the Touch HD.. Greez, cad^^

I guess no problem with playing video
http://www.youtube.com/watch?v=Fv9lLAVidgA&fmt=18
Thanks to johnkorver who own the device, create the video review, and upload it to youtube.

looks promising even though we don't have any other info on the video file except the codec used (xvid).. anyway upscaling works nice and that says much..

one more video playback demo: http://www.youtube.com/watch?v=Wo7I6K8U7L4

3 more video's showing off... great video playbeack

With this dutch review http://www.winmo.nl/?p=966 of the HD there are 3 youtube video's posted that show of great performance...

The review also confirms that the HD uses dedicated hardware (Qualcomm QTv videochip) to accelerate the video performance.

if you go by this post, the benchmarks very low (though the OP claims that the video was fluid.)
the problem with htc is that even though a dedicated graphic accelerator is/ would be present ,HTC has till date not allowed 3rd party (read coreplayer and co.) to utilize it

I was watching the HD video with a great interest and then tried to follow the same on my Diamond and there is no noticeable speed/responsiveness difference.

Don't forget that the benchmarks probably are not using the full potential of the hardware or are using it badly.
And as we all know, benchmark is a benchmark... only the true experience can tell us if it's good or not...

that would be because of HTC not releasing the details of the graphic accelerator to 3rd party developers.
although i do agree that it is the real experience that counts, benchmark help people like me who without the device make a comparison with there existing devices.
on a side note, "the real experience" varies with different people some people are happy with 200 kbps qvga encodes others want 2500 kbps vga encodes.
My personal experience is that anything under 124% stutters.
P.S does anyone know if it has a dedicated h.264 decoder (which would enhance battery life )

Video recording framerate

Is the HD capable of 30fps or not?
I recorded some videos using CIF resolution (both mpeg4 and h.263 format), then transferred them to the PC and used VLC to play them and see "Media information" for them.
- for some of them a framerate of 5 (!) is reported
- for some other a framerate of 15 is reported
No 30fps anywhere! And there is no setting to adjust framerate in the options. Am I missing something here?
Is maybe the framerate not constant for these types of formats? Maybe depends on the lighting conditions? Even so, the 15fps videos were recorded in broad daylight on a sunny day! How much more light do you need?
What's the deal?

MSM 7201A cpu have the ability removed in hardware because of a patent lawsuit

So chipsets with "a" in the ending have this feature removed? Are there any Blackstones with the "normal" version of this chipset?

not a but the ones ending with 1
don't know for sure looked at wiki and it said the blackstone had 7201
as cpu which is the version where the capture was removed
7200a in x1i the international version should include the feature
but the x1a usa version got the 7201A which don't
but even with 30fps it's pretty crap imho compared to real cameras with CCD chips
unlike the cmos chips of mobile phones
much like the eternal mpixel confusement race it's more hype then real quality

What "ability" do you mean? 30fps ability?
And if so, then what is the ability we' re left off with? 15fps? That the maximum?
Also would someone know why other videos are 5 fps and other 15 fps?

X10 W/2.1 720P Video recording <24fps

Ok so im not a professional at this or nothing but the 720p video recording was supposed to be as per the same execution as the vivaz which is 24fps right....so since I have update my X10 to 2.1 and have recorded a few videos in hd, when I check the details im only getting anywhere from 14-18fps. I don't have one video yet that past 18fps....why is this happening? Not sure if the sd card has anything to do with it but I do have a class 6.
Oh...by the way guys,,,im not complaining about it...I think the video looks pretty awesome...just really curious tho.
Sent from my X10i using XDA App

I have a class 2 that came with the x10 and I got about 20-21fps @ 720p with my first tests but the frame rate of videos captured w/x10 is variable so at any given time it could be lower or higher than that. But these are higher numbers than I was getting @WVGA resolution on 1.6(17 or so fps) and I haven't had time to test but 1 or 2 vids on 2.1 so I'm eager to see if WVGA is at better, more constant framerates.
What are you using to get fps info? I use Mediainfo and it wouldn't touch the 3gpp MP4 container the video is captured to. I went to mux(multiplex) the audio & video streams to a readable MP4 with YAMB and in the YAMB selection window Mediainfo finally showed
Code:
MPEG-4 (3GPP Media Release 4): 23.1MiB, 32s, 64ms
Video: 6183 Kbps (6000 Kbps), 1280*720 (16/9), 21.970 fps, MPEG-4 Visual (BVOP)
Audio:64.0 Kbps, 16.0 khz, 1 channel AAC (Version 4) (LC)
So I went on to mux them and got the full info from the resulting MP4:
Code:
Video
Format : MPEG-4 Visual
Codec ID : 20
Bit rate mode : Variable
Bit rate : 6 014 Kbps
Maximum bit rate : 7 771 Kbps
Width : 1 280 pixels
Height : 720 pixels
Display aspect ratio : 16/9
Frame rate mode : Variable
Frame rate : 21.367 fps
Minimum frame rate : 9.259 fps
Maximum frame rate : 31.250 fps
Resolution : 24 bits
Scan type : Progressive
Bits/(Pixel*Frame) : 0.305
So as you see the video ranges from as low as 9fps to as high as 31fps.
I am hoping someone will find some editable settings somewhere in the Video camera app so we can tweak it to perform at a decent, constant framerate, maybe at the expense of some of the bitrate or peak framerate. 24fps would be great if possible.
The audio is really bad..
Code:
Audio
Format : AAC
Format/Info : Advanced Audio Codec
Format version : Version 4
Format profile : LC
Bit rate mode : Variable
Bit rate : 64.0 Kbps
Maximum bit rate : 69.9 Kbps
Channel(s) : 1 channel
Sampling rate : 16.0 KHz
Resolution : 16 bits
They are clearly trying to keep audio as small as possible & putting all emphasis on the video but IMO you could make the audio just slightly better at not much cost to total file size or encoding power since it's just AAC-LC. Higher peak bitrate & Sampling rate would help for sure but I'm not an expert or anything so I don't know how all of this would affect the 'total package' and video performance.
But all of this is just speculation by me and I have somewhat limited knowledge on the subject. I think they did a good job and picture quality is actually pretty good!- I'd just like to see a video capture app that performs more smoothly or is more configurable.
The values below are from "default-capability.xml" on my sd card. I can't tell if they are profiles fore encoding or decoding but I wish they were possible somehow!

Well that was a bit long-winded and no real solutions were given but at least you know more about the video and I've been wanting to talk about it anyway

Wow.. I cant even get to record Hidef.. After a few seconds of recording, stopping it. Then my x10 tends to stall... its problaly my class 2 card that needs to be formated or something..

@uphiel: yes, I would recommend a class 4 card at least....I went out tonight and bought a class 6 because I got a pretty good deal.
Anyways, I was getting my details on the video straight from the standard 3d gallery in 2.1.
However, since this post I did read that lighting situations have effect on fps. Lower light situations tends to lower the fps, as all my videos were in somewhat lower lighting.
Im gonna try tomorrow in bright daylight and see what kind of results I get.
I should add...that even tho I wasn't getting any higher than 18fps...my videos were NOT at all choppy...they were actually VERY nice...I cant post any samples because the vids were of my daughter lol. I thought the sound of the videos were also pretty clear and loud.
Maybe Ill post a test video in this thread tomorrow of what I get in bright daylight.

I think it's just a variable framerate. When there is a lot of movement the framerate is higher, when there is only a bit movement the framerate is lower. It's how mpeg4 works. It's a form of (losless)compression.

Ok so its early morning here and I just took a quick video out in my backyard. I can confirm that my above post is correct. It's still not really bright outside right now but it is daylight and I just hit 23fps. So it seems true that the "lighting" will have a effect on the fps. Ill take another video later in the afternoon when its even brighter out...maybe ill hit higher than 24fps.
@LahiruRD: I dont exactly know how he posted a detailed log like that. But when I first updated to 2.1 I only had a class 2 card. I did have some choppy vid but it really wasn't bad at all. But yesterday evening I purchased a class 6 card and just in the few videos I took with it I did notice a nice difference. No lag whatsoever, video was silky smooth

I only had a quick testshot with a lot of static zooming to test the autofocus and wild rotatation and the fps are about 20 but the video doesnt seem choppy at any point.
btw. i got a class 6 card. I will have a try with some moving objects next week.
edit: I watched the clip in qt classic (displays not the most exact framerate) and while moving it was about 24fps and when static down to 16. it seems that its really more the dynamic framerate effect.

I did a HD video recording at college and i was majorly surprised.

What is exactly the difference in video qualtiy when using a class 2 or 6 card?? this morning i recorded a video which was really laggy and this evening i restarted my phone and the video was very nice, i recorded my monitor and i could even count the pixels!

class2 should at least transfer 16 mbit and class6 48mbit, however video bitrate is never above 8-9mbit.
but you get a lot more reserves for peaks in bitrates and if some other application access the card while recording.

and this the video comparisons which i did few days back with iPod Touch 4 and our X10.

mind the spaces.

I recorded first a video with a 16gbs Class 2 microSD and the FPS was 18
After I used a 8 Gbs Class 4 microSD and the FPS was 16
So, what's the best way to obtain a 24 FPS HD Video?????
-------------------
I formated the class 4 microSD and the video now is on 18 FPS.... damn...

as stated above, the framerate depends also on the scene youre recording not only on the technical possibilities

Sometimes when I watch HD videos on youtube with 720p or 1080p I notice a jerking effect in the video. Is this because of low frame rate or absence of graphics card in my computer. A friend of mine was saying the other day that if install a good graphics card then the issue will be solved and I'll be able to watch smooth HD videos including those recorded by me on Xperia X10. Any comments, guys? Will this work?

Hi everybody
I see the Xperia x10 hardware is fully capable of [email protected]
but the only question is why it is not happening and how to make this happen
I see in froyo there is an media_profiles.xml in etc/ but in eclair it don´t exist
look at these pages to see that xperia is fully capable

Sony Ericsson stated themselves that the 720p video recording on the Xperia X10 would be as the same execution as the Vivaz which is 24fps NOT 30. I have been able to get 24fps a couple times now, but it all depends on the scenery and lighting. I dont think 30fps is possible on the X10.

I just did a video recording test of my wifes iphone 4 and my x10, my impressions were that the x10 colors are much much better and more real, the iphone makes everything yellow and adds a glow?? Also the AF works like a charm where the iphone not so good as you have to tap to focus most of the time. However i can say that the fps is much lower on the x10 and can notice a huge difference hope we can get this fixed once the devs crack the bootloader.

did you notice a lag or stuttering or was just the framerate lower?

This is off-topic, but yes I believe that will work. It doesn't even have to be a 'good' graphics card, any new Nvidia or Ati card will do probably. Flash video is hardware accelerated by the graphics card these days, see this site: http://www.adobe.com/devnet/flashplayer/articles/fplayer10_1_hardware_acceleration.html
