Some weeks ago i was thinking in a Motorola Atrix to replace my old HTC Hero.
It's a good device but after some questions...

If you want to play H.264 high profile movie, DO NOT BUY Tegra2 based devices.
common 1080p(BDRips) are MKV(Container)+H.264 [email protected]~5.x+DTS/AC3 audio.
Tegra2 have hw limitations to play H.264 High profile.
My recommendations are
1. SGS2 : 1080p/1080i(it can de-interlace with HW)
2. Sensation(or Dualcore Snapdragon equipped devices) : 1080p capable but some shutter occur when you playing high bitrate movies.
3. Galaxy Tab(7inch) : can play 1080p
MKV container and DTS issues can be solved with Diceplayer.

My question now is:
How do OMAP 4430 'handles' MKV 1080p High Profile/high bitrate?
I've read that 'theoretically' OMAP should be better in 1080p decode that Samsung Exynos.. Is this truth?
Another question...:
Someone knows the difference between OMAP 4430 and Galaxy Nexus OMAP 4460 ?
Cpu i think it's the same.. probably its the mhz on PowerVR SGX540 right?
yes.. Droid Razr will be my next phone.
Thanks in advance.

Diceplayer does not support OMAP4 yet.
Samsung's video decoder implementation is much faster and powerful than TI's implementation. Samsung want to use Exynos to their TV and Settops. So Samsung AP's video decoder accept all of H.264 profile & level.
Exynos and Hummingbird support Zero copying rendering. it is much faster rendering than OMAP4's V4L2 overlay rendering.
Thanks for your help Juami..
That means that diceplayer dont run on android's with TI OMAP4?
Galaxy Nexus have a OMAP 4460.. i guess there will be support for OMAP in [a near] future right?
About OMAP4's V4L2 overlay rendering... is better then the rendering/decode engine on Dual Core snapdragons [HTC Sensation/ Sensation XE]?
Thanks
Hi guys,
I am currently using Android Revolution HD 6.5.1 XE on my Sensation and I have several major problems:
1. I realize that 1080p mkv videos that my phone can play smoothly on Gingerbread (including Youtube HD 1080p) now become laggy. Even with SD videos (fully HW accelerated), sometimes the playback is choppy as well (I use MX player and Dice player). Can anyone help me confirm whether you have the same problems? I believe ARHD ICS does not have GPU overclocked as on Gingerbread, hence the choppy video playback.
2. On random occasions, I cannot get any sound on any applications, but notification sounds and stock music player are working normally. I can still listen to music through the stock player but cannot get any sound for videos. Everything will return to normal when I restart the phone.
3. Wifi randomly turns on by itself. The last time I check, this problem seems to be unsolved, but I may be wrong.
Any kind souls willing to give me some directions to solve the above problems? ARHD Gingerbread ROM does not have any of the problems above, but I don't want to go back to Gingerbread.
Bump, still waiting...
Imo bad flash, I never had those problems. Video playback even on flash has been buttery-smooth.

And yes talking 1080p video.

Yes, ARHD ICS does not have GPU overclocked. But that shouldn't be the reason for your video playback problem. Because of your other problems I also believe in a bad flash...Try a reinstall.
Bad Flash or using a wrong kernel.
I have tried flashing the ROM 3 times (also redownload the ROM, check md5), with both stock kernel and Sebastian's kernel (at 1.2, 1.5, 1.7 Ghz) and the video playback is still quite bad. I just flash the latest 6.5.2 on my Sensation and it is still the same problem with video playback. Just to confirm, can you guys watch 1080p youtube hd video without any problems?
The playback problem disappear straight away when I go back to GB.
Like I said, yes, I can. In both the app and on Browser with flash player.

Video Choppy
Hey man, in MX player, are you hardware accelerating or software accelerating?
I noticed that HW accl is laggy, buy software accl is smooth

Yes, I am sure that I play my videos with hardware acceleration, and about your observation, I beg to differ. The way I understand it is like this: with hardware acceleration, the task of video playback is offloaded to the GPU, hence better rendering, frame rate and better battery performance. If you use software rendering, the whole task is given to the CPU, which will need to run at full speed to decode, and there is no guarantee that it plays smoothly. For instance, on my Sensation, without hardware acceleration, 1080p videos are impossible to play.
I am still trying every possible solution to my video playback problem. Yesterday I also tried Sebastian's latest kernel, with GPU overclocked, the frame rate is getting better, but it is still not on par with Gingerbread's performance.
Any other suggestions?
I think my description was not clear enough. The correct word for my situation is actually micro-stuttering, it is similar to situations when you are playing computer games with either nVidia SLI or ATI Crossfire.
I officially give up, don't really know how to solve the problem now.
why dont you try flashing another rom?
you keep saying its ARHD fault so flash something else and see?
Even i am facing this problem on my XE. mkv high bit rate videos ( more than 10mbps) are having micro stuttering. Hell even 720p hight bitrate videos. I am coming from galaxy S2 and these high bitrate videos used to play buttery smooth. Cant adreno 220 handle 720p videos? this is shame. i can say 1080p mp4 videos are playing fine though.

I will try other ROMs when I have enough free time, but someone told me that it is the same problem for all ICS ROM on the Sensation.

I just want to clarify with you: there is no problem with video playback on Gingerbread, only on ICS that the problem occurs, so it really ROM-dependent, you may want to give ARHD 4.1.13 a try instead of those latest ICS ROMs. Having said that, it is a known fact that Mali-400 MP has much higher performance than Adreno 220, even in terms of graphics and video playback. I think h.264 high profile videos with higher than 10mbps is too much the Sensation, it is a hardware limitation after all. If you want to watch any videos without problem, the ASUS Transformer Prime is the only choice.
Just for curiosity - why bother playing a 1080p file on a device with a (much) lower native res?

There are two important reasons:
1. There is no need for conversion. I can use the same files for my laptop and my phone.
2. Quality: It is all about the video quality, you just have to see it to believe, it is just like day and night. You can put 2 youtube videos with SD quality (say 480p) and full HD quality (1080p) on your phones (in this case, the Sensation) and compare them side-by-side. Image quality, colors, details are much better on full HD and the differences are obvious, regardless of your phone's native resolution. In a sense, it can be comparable to your laptop situation: should I buy a Blu-ray movie to watch on my 720p screen laptop? If you have watched Blu-ray movies before, you definitely will know the answer.

Understandable, even though cheap storage and batched rips minimalize the effort.

Yeah, because you compare apples and oranges.
Obviously a downscaled 1080p looks better than an upscaled 480p.
Also, the used color space is not bound to the resolution.
And yes, a BR will look better on your 720p screen. Obviously. DVDs are 576 mpeg-2 encoded ^^

I have, and i agree. But one should think trough why, and when it makes sense.
No offense, one should do whatever he wants to do.
I (but that may be me) would rather have a 540 movie with high bitrate than a 1080p with a lousy one, just to say "hey, it's HD"

Did u try stock ICS ROM?
My Galaxy Ace Runns with TheMyth ICS ROM. The CPU Frequ is 942,7 MHz Overclocked.
But i can t Record Videos in 720p.
The I Phone 4S Records 1080p with 1000MHz.
THX for answers.
You can't record 720p natively on the Galaxy Ace as its a limitation of the hardware. The iPhone 4s has more memory (1GB) and its processor is dual core. There are apps out there to allow 720p recording but I doubt you would get a smooth frame rate. The Galaxy Ace only has 384mb of RAM. Also the app has to allow the 720p recording for the specific phone model. LGCamera pro does support HD recording but some users have complained that their phone is not supported.
With lgcamera pro ..
