[Galaxy S II Q&A, Help & Troubleshooting] deanwray:
at the end of the day though, tis a phone, if you want really good quality get a pro sumer hd cam, or a 5dmk2, or if you won the lottery get a Red Epic and shoot 5k res at 1000's fps. However none of those have mail/chat or phone capabilities :)
[Galaxy S II Q&A, Help & Troubleshooting] fenomeno83:
for 1080p are taken 1920x1080 pixels from the center of 8Mp sensor... (in this manner there is a "zoom effect" of about 2x and less view)

for other resolutions are applied pixel binning tecnhique (all pixel from sensor are used, and is scaling from 8mp to output video resolution)

take original pixels produces better quality (because are original pixels and not scaled), but less signal/noise ratio (but, because galaxys2 sensor is good, noise is low also if you take original pixel and don't use pixel binning that increases signal/noise ratio)..

also, use original pixels and don't use pixel binning, requires less power (in this manner you can have 1080p video at about 30fps and high bitrate)
[Galaxy S II Q&A, Help & Troubleshooting] DrSlump76:
Ok deanwray, you're perfectly right, but i would prefer to choose by myself if i wish to use the zoom or not, awared that if i use the digital zoom, the quality will be affected. In the other hand, in this way, the 1080P video would have better field of view (instead of the zoomed effect we have now) and less noise.

About the bitrate: maybe it's possible to raise it to 20Mbit, but i think that going above this limit is quite difficult. According to me, it's better to implement the zoom in 1080P and a better audio recording.

I was thinking: if they're unable to implement such features... how can we hope to obtain higher bitrates.. :D ?
[Galaxy S II Q&A, Help & Troubleshooting] deanwray:
If it's not firmware (camera firmware) limited, there are calls in the android sdk to set bitrate, I would probably look at writing a camera when I have time. Never looked at attempting to mod the default one. Have found something odd though, did a few tests, and there should be perceptual zoom due to sensor cropping at 720p, but compared against an 8mp photo, there aint! :( So thats a bit wierd to me :)
[Galaxy S II Q&A, Help & Troubleshooting] DrSlump76:
According to you, is it possible to modify/create a camera app that implements a digital zoom or better algorithms for image sampling?

What kind of access is possible to gain to the application processor's peripherals with android os?

There are some realtime image scaling algorithms that could be implemented via gpu or, better, via dsp if the exynos integrates a dsp onboard (like the TI's omap do).
[Galaxy S II Q&A, Help & Troubleshooting] deanwray:
The only thing I would look to change is the video bitrate. Or if android allowed aperture ....... although looking into it, it's a camera firmware feature. Any hardware acceleration outside the bounds of standard android I would not attempt. Since the full hd vid is 1.7 cropped, is it really good to have digital zoom? Will be like looking through a telescope :)
[Galaxy S II Q&A, Help & Troubleshooting] karl999999:
general user

ok , so after reading the whole thread (not being an expert in this field) I am confused.

i have a "simple" question:

should i use 720p or 1080p for recording videos with the SGS2 ?

(what do u guys recommned for the normal user?)
[Galaxy S II Q&A, Help & Troubleshooting] JonesWTF:
I have also read the while thread and have a few ideas. Forgive me if I have misunderstood.

From what I understand, 1080p uses the center of the sensor too achieve the higher resolution over 720p, but this creates the zoomed effect.

If we could use the whole sensor to record at 1080p, in theory, shouldn't this stop the zoomed effect and leave room for digital zoom for those that want one?

I personally am not a fan of zooms on phones, I just stand a bit closer.

Am I right in what I am saying, our have I misunderstood entirely?
[Galaxy S II Q&A, Help & Troubleshooting] deanwray:
Misunderstood mostly, as if u read back, you would know it doesn't fit!

also, would be a little obvious ;)
[Galaxy S II Q&A, Help & Troubleshooting] Tinderbox (UK):
I don't want to hijack the thread but on a similar question , why when taking a self photo using the from camera does the photo get mirrored as soon as you take the photo , example you were looking left, after you take the photo you are looking right ?????
[Galaxy S II Q&A, Help & Troubleshooting] deanwray:
Way off topic but gonna look :)

Ooo, cool, but common sense tells me it due to the possible dissorientating affect if it didnt operate like a mirror

[Galaxy S II Q&A, Help & Troubleshooting] DJ-Mills:
solution?

With some of the lastest releases of cm7 and lgcamera you can select resolution 1920x1088 and that appears to be fully zoomed out. However when ending the recording it just hangs, does anyone know a solution to this?
[Galaxy S II Q&A, Help & Troubleshooting] DJ-Mills:
Nobody have any ideas or any kind of hope?!?!?
[Galaxy S II Q&A, Help & Troubleshooting] DrSlump76:
Select the 1920x1080 resolution, it will not hang anymore.

Supported HD resolutions by samsung galaxy s2 are:

1280x720

1920x1080

Avoid other resolutions.
[Galaxy S II Q&A, Help & Troubleshooting] DJ-Mills:
Well yes of course but the 1080p mode might as well be 720 but closer up thats the problem. It zooms in on 1920x1080.
[Galaxy S II Q&A, Help & Troubleshooting] DJ-Mills:
Does nobody care that we dont have a propely functioning device because of this??????
[Galaxy S II Q&A, Help & Troubleshooting] pachi72:
True.
[Galaxy S II Q&A, Help & Troubleshooting] 11768:
Autofocus during low light is far worse than this.
[Galaxy S II Q&A, Help & Troubleshooting] DJ-Mills:
Still nothing?
[Galaxy S II Q&A, Help & Troubleshooting] darkphantom:
I just looked at that comparo of the 1080 vs 720 recording and was shocked!

Guess i'll be recording in 720...until the fix. Which isn't bad though, but just not 1080...

[Galaxy S II Q&A, Help & Troubleshooting] DrSlump76:
It's due to the firmware written for the isp chip. Who (as me) has the firwmare ver. SCF02, coupled with the samsung sensor, has the worst performances at all, that means low framerate in low light, bad focusing in low light, plus all the problems here discussed.
[Galaxy S II Q&A, Help & Troubleshooting] DIGIDIX:
Sure, but that's the reason that I've moved from acer ( cheap products ) to samsung, but now I realize that even samsung is a cheap trademark even if it's worldwide famous, now... the best should be HTC or even Nokia

Any idea for a working camera hack or even say my idea to a developper ?

My idea is to take the Field Of View algorythm of the 176x144 recording resolution, put it in 16:9 and inject this in the 1080p mode or remake all the resolutions with this 176x144 field of view who are the best !

thanks, i'be been looking for feedback regarding adreno 220 vs mali 400 GPUs, do you have any link or source to back this up

I am looking forward to buying the sensation, and my only concern is the adreno 220 GPU as and whether it is better, equal, or workse than the Mali 400

If it is better then i'm definitely buying the sensation, if not then i might consider the galaxy s II

Thanks
[HTC Sensation] boostedb16b:
interesting read... the sgs2 fans will debate this and say that the benchmarks were done with an over clocked processor.. so as of now its all just a good read

[HTC Sensation] boostedb16b:
another thing is that sony went with the adreno 220 in the xperia play so i guess it is as good as they say it is
[HTC Sensation] MiKA7:
Actually they went with the Adreno 205 in the Xperia Play, which is the same gpu as in the Desire HD
[HTC Sensation] umd:
Isn't it Adreno 205 ?

http://www.gsmarena.com/sony_ericsson_xperia_play-3608.php
[HTC Sensation] eXceed:
Adreno 220 is faster than Mali-400MP anyday, and compared to Tegra 2 it's better in some cases and worst in others. I didn't get a Galaxy S2 due to the fact that the Mali-400MP is soo antiquetted...
[HTC Sensation] Beaker491:
According to reports on the SGS 2 forum, the Mali 400 doesn't support textures? This seems a big blow on the SGS 2's gaming capabilities to me. What would be an interesting comparison would be the Adreno 220 vs the (LG Optimus 3D's) OMAP4 PowerVR SGX400 GPU, which is clocked at 300MHz instead of the 200MHz found in the samsung hummingbird processor....

[HTC Sensation] Elchemist:
Mali 400 Does support textures its texture compression which it does not support.
[HTC Sensation] i9100:
It does support texture compression, just not the proprietary formats of other GPU vendors. Developers that only code for proprietary formats get locked in and lose out when something better comes along.
[HTC Sensation] boostedb16b:
i surely was waiting for an idiot response like yours i9100 just face it that samsung made a mistake with the mali... and to be quite honest with you the sgs2 was rushed out to take the lead on the market b4 the sensation.. and the cpu was overclocked to be more competitive with the sensation... and the rush has shown what i expected lots of unknown problems in the phone and then returns for phones with faulty screens and so on so dont be a troll and state facts rather than just talk because you have the device
[HTC Sensation] eXceed:
Mail 400 is just an outdated chip, why someone wouldn't include texture compression in a MOBILE gpu is beyond me. What the hell were they thinking?!! The PS3 only does this because it has a blu-ray sized storage media! Ridiculous.
[HTC Sensation] Currykiev:
As stated, it DOES support texture compression. There are just a few formats and it only supports one of those. It won't prove a problem as it seems the SGS2 is going to be extremely popular and all game devs will support it eventually (most do already) :-)
[HTC Sensation] Currykiev:
Wow, that was a slight over reaction! Do you work for HTC or something because that was a very defensive reply.

i9100 actually speaks some truth. There is a very informed topic over on the SGS2 forum about this which i suggest you guys read before making any more statements which are incorrect.

Still, looking forward to seeing this phone released to see if it's as impressive as the S2 is. I'm hoping it will be. :-)
[HTC Sensation] kgbkny:
I wouldn't be surprised if that was the case. To Samsung, that's business as usual.
[HTC Sensation] i9100:
I'm biased and this is not the Samsung home turf so I'll just keep to correcting facts. A little flaming is fine and not unexpected, but I won't go there. I'm enjoying my phone, and you should enjoy yours ;-)

In OpenGL ES 2.0 there is only one standard texture compression format - ETC. It's the only one you can rely on in all conformant GPUs. Others like ATITC, PVRTC and S3TC/DXTC are proprietary formats not suitable if you want your app to run on new devices.
[HTC Sensation] boostedb16b:
at the moment since my hd2 has been retired i opted to buy a samsung galaxy s 4g worst mistake i have made in a long time... bought a sidekick 4g for my gf and that phone was another example of how poor quality control if for samsung or how they rush to get a head start in the market... the phone is riddled with problems
[HTC Sensation] boostedb16b:
lol its not as bad as what i have read in the sgs2 forum where people are reporting their problems and trying to get legitimate help and are being bashed and called trolls because their phone honestly has a problem
[HTC Sensation] :
Yep, i think samsung users are morphing into apple fanboi like persona's.

I will never buy a samsung product again as they can NEVER get there screens right... I would say 1 in 10 are decent. The whites looks a tingey off green, yuk;(

lol yup i think that is what samsung wanted because the pretty much have the i clone so why not have the fanboys too

I've been saying that since witnessing many Galaxy S owners become obsessively protective of their phones, flaming anyone who dares say anything negative about it.

I am neutral on both sides as I used a desire befor and now switching to a SGS2, they all provide good experiences and I respect both companies to make quality products for their customers.

Sure there are many topics in SGS2 forums posted by people having problems with the phone and I am glad that I have a fault free model, however I still enjoy reading "problematic posts" for informative replies and sometimes sharing my ideas, this is what xda suppose to be.

Come on guys, they are both good devices, less flaming and we can work together to make things better :D:D

coming back to the original topic (lol), yes Mali-400 is a strange (possibly BAAAD) choice by samsung and I am expecting adreno 220 to be a better GPU, but let's wait for some more reviews to see how sensational this little baby is.

**edited the post for a more peaceful and productive discussion :P**
[HTC Sensation] Currykiev:
Actually,if you were to count every game on the market, then count the tegra only games it is a tiny percentage.

Also don't forget that some areas will be recieving tegra powered SG2's.

[HTC Sensation] alireza_simkesh:
would be interesting to see which one is truely the real winner...without any biased comments or false info or anything like those....
[HTC Sensation] Beefheart:
Strange that the GS2 blows the Sensation out of the water on every graphics benchmark test in that case, and in particular the recently released NenaMark 2.
[HTC Sensation] clouds5:
Benchmarks are cool for direct comparison of chips working the same way. So for example when you compare chip x with 500mhz to chip x with 750mhz. But if you compare chip x to chip y and the benchmarks coding favors chip y then it says nothing about which chip is better.

That could be the case here. In the end it all comes down to what the game devs out there are gonna do with it. With android its almost the same situation we windows (PC) gamers have. Hardware is completely over the top awesome fast with newest shaders and stuff (dx11) but games get developped for other systems (which are quite old and very slow in comparison) like the xbox360 and then ported over. So noone needs the hardware except for the benchmark junkies (no offense ;) ).

So "high end" mobile phone games are being produced mainly for iOS. Gameloft ports almost all of their games over to Android which is very nice. But other than that...?

So yeah if you just look which dualcore chip is the most powerful stats wise - from what i've read its the Adreno220. If you look at the benchmarks everyone yells Mali400.

BUT if you look which chip actually runs any games right now i'd say the best is Tegra2 (And i'm an Nvidia hater!). From what i've heard the Sensation has some problems with 3d games because of the resolution? And Mali is generally strange and games have to be adapted first (just what i heard+what i read). Tell me that i'm wrong if i am!

And if you really want to play games, get the experia play. Although it has an old CPU (same as my DHD) it has the largest library of games and some really really good ones like GalaxyOnFire2, BruceLee fighting and stuff.

Android gaming needs help! What i dont get: in the end its all OpenGL 2.0, is it? So when a dev codes for OpenGL it runs on all chips. At least thats the logic assumption for a programing noob like me :) So where's the problem? Are those chips so different?
[HTC Sensation] intruda119:
^^^

With chainfire 3d drivers most games can be played with the sgs2-mali gpu with a apk tweak. I think the Mali is the better all around gpu for gaming and media. From what I read its as simple as devs using a converter or another universal type of game compression.

We want see anything soon that will tap the power of any high end android phone. I personally think samurai 2 looks beautiful on sgs2 and moto atrix(qhd).
[HTC Sensation] clouds5:
Yeah Samurai II also looks very nice on my DesireHD with Chainfire ;) And it also runs perfectly on my 2 year old ipod touch with 600mhz...

Thats my point, its all about optimization. And xda devs are awesome anyway :) i think android would be half the fun and usability without them!
[HTC Sensation] neelpatel007:
