Good friends, I wanted to know that such see the exynos 5420 processor, 3GB of ram the gpu mali T628 MP6? I mean for the future and so on? about games and stuff? it does not fall short on power, I just bought the tablet and love but I like to have years ... as you see?
One thing i miss is no hardware accelerated support for the new H.265 video codec over the H.264 codec we use now which makes the video file up to 50% smaller they can be played, but only using the cpu to do software decoding, and not gpu hardware decoding which use more power to decode them.
Also no native ac3 audio decoding for the stock video player without rooting the tablet, older tablets have ac3 support but it seems Samsung cheapen out on the royalty's to use the Dolby ac3 codec.
John.
first of all, there is no such thing as future proof gadget. As technology have become advanced day by day so present will become old in the future. BUT, as to date, tab S have the highest spec among all tablet from all manufacture and because of its lightweight, it's portable enough to be brought anywhere

Okay, so I know absolutely nothing about ROMs, so this is mostly a question of if this is possible:
Currently, the EVO's 720p video recording is lackluster. I find that the biggest reason for this is the bitrate of the video used. I imagine that the bitrate used on the video was to accommodate the included microSD card's Class 2 write speed.
Is it possible to increase the bitrate used for encoding of this video, to something ~5mbps, to which a Class 6 microSD could handle just fine? Ideally this could even be implemented as an option in the camera app, so that those who don't have/can't afford a class 6 microSD could still use the ROM.
If that is possible, what are the chances of having the video also record using a different audio codec? The current codec used is pretty much impossible to play back in anything except Quicktime (VLC's latest release candidate just added support, but it still sounds awful, like a pack of hyenas on top of the track). I'm really not particular on what audio codec is actually used; be it mp3, ogg, etc, as long as it's more easily played.
The best case scenario, the DREAM EVO ROM for camera capability for me, would be:
1. At least double the bitrate (4-5mbps) for the 720p video with an option to use old settings.
2. A better audio codec using higher quality settings (minimum 64kbps mp3/ogg/similar) that is playable in many more programs.
3. A more compatible container format like mp4/m4v.
Am I dreaming or would this be possible in a custom ROM?
Don't forget it will also be limited to how fast the hardware can encode the video. Someone with the right skills will have to push the hardware encoder to see how high they can push the bitrate without exceeding real time.

Yes, there might be hardware limitations, that's sort of what I'm asking; if this is something that can be "fixed" in a ROM or if we're stuck.
I think as long as it can handle the bandwidth though, I don't see why the chip would be incapable of higher bitrates. I'm not an expert on the matter, but I thought that the less compression/higher bitrate something is, the less power was required to make it happen.
well im pretty sure this is possible, if a dev puts the time and effort into such a large project. i only say this cause the nexus one recently got 720p video recording, something it didnt have from the start. and i think its known that htc made the video recording compressed, so i think theoretically if we lift this compression and use a different form of compression, we can get higher bitrates from the video.
Yeah, I'm hoping a developer can investigate this thoroughly. Even if it takes a while, it'd be nice to know someone is at least looking into it.
And to make it worth their while, I'd be more than willing to pitch some donation funds towards such a project when it becomes successful. I doubt I'd be the only one as well.
I was wondering this also. I'm not up on the technical aspects of this, but I was also wondering if the 720p could be improved through software fix/ROM development? I agree also that I'm sure a lot would be willing to donate for such a fix.
I'm sure eventually we will get a better cam, i mean look at the how the nexus got 720p video
You can easily get 720p at 60FPS... The snapdragon can support it.
i would most certainly donate for this improvment
yup i would donate as well
we just dont have as lively a development community as the nexus yet, but we will in time - we;re gaining momentum fast

Is that encoding or decoding? And at what bitrate?

Go look at the Nexus One forum... They've got up to 1080p capture.
Realistically though, it seems silly to rely on our phones to capture HD video. I have a G9 that does that task quite handily.
All I could find was 720p capture at 20fps and a max bitrate of 12Mb, which is plenty.
This is interesting, I'd like to see this happen as well.
I'll do what I can in terms of research.
Better low-light pictures too, if at all possible
Are there already codecs for the tegra 3? @ the moment if I run a movie for a while. The HOX us getting really hot, I think with the right codecs the cpu have to do a lot less work.
Sent from my HTC One X using XDA
ARMv7 codec is included by default with MX. So no need for special codec for Tegra 3.
Yes it does get warm, it is to be expected.
Please next time, define better "really hot"...I've gotten all the latest updates on my stock(unrooted) One X and the phone gets warm (not hot, it applies to temperatures above 50 degrees celcius) like a "pie", but nothing really uncomfortable, it's much like the iphone4 I used to have, the same amout of heating actually. And as the above poster said, the MX player, does have the newest codec for the Tegra3 chipset.
I am planning on getting a Sprint Galaxy Nexus (have too many unused upgrade lines lol). And I was wondering how it performs on 720p 10bit video. From what I read it is able to play on MX Player, BS Player, Dice Player but I am more worried about performance. Some devices I hear have issues playing 10bit high action scenes so I want to know how it does. And if anyone has any experience with this?
I don't know but the nexus decodes 1080p video at the hardware level due to its chipset, not software like many phones. So it handles video playback like a champ.

I don't think any phone can do hardware decoding of 10bit video. 8bit video even a 1ghz single core hummingbird can play back 1080p with hardware decoding. But I am more particularly interested in 10bit which is more then likely decoded via software.

Can you point someone to where they can download a 10bit video and test it for you? (Maybe just a short clip?)

OK I found some samples online:
There are 2 10bit 720p samples here:

Downloading one now I'll let u know.
OK, those are mkvs and the stock video player can't play them.
Sent from my Galaxy Nexus using xda app-developers app
try vlc beta or mx player. H/W decoding might not work with these files but software playback could be fine in theory.
MX Player can decode 720p 10-bit (Hi10P) files using its software decoder but it's very slow. You'd better off reencoding them using Handbrake.
PS: Even without action scenes, 10-bit files lag on the GNex.

Well I am able to play back 10bit 720p on my Droid Charge so as far as playback it should be able to do it, the problem is performance. the droid charge isn't powerful enough unfortunately.

Well if I am going to transcode then it kind of eliminates some of the purpose. Have you tried in MX Player to set it to use both cores? fast mode? 16 bit color depth? overclocking the phone? None of the above would help?
10-bit H.264 is pointless. The screen (most likely 6-bits per channel with dithering) can't even display that many colors.

There are other benefits to 10-bit. The compression gives higher quality and smaller file sizes. Also the screens last I checked are not crappy TN panels. Super AMOLED is more then capable of displaying all colors. Even the IPS screens on phone these days are Super IPS (not to be confused with eIPS) and should be capable of displaying 10bit color.
That the format of the video is what it is and transcoding is not an option. Hence why I am interested in performance.
Don't expect anything but horrible performance. 10-bit H.264 streams can't be hardware decoded by anything on the market and probably never will.
Most S-IPS panels are also 6-bit per channel with dithering. Very few are actually 8-bit. Now, as far as monitors go, unless you're willing to spend 10 times the price for a non-consumer model, you will not find anything that supports 10-bits per channel natively. The story holds true for phones, too. I don't believe there are any 10-bit screens and I'm sure there won't be any for years to come (again, unless you're spending thousands for a phone).

First of all Super AMOLED has full color support because its not an LCD. The only thing you need to do is calibrate the screen so its not saturated. If you take OLED decay asside OLED can give you perfect color reproduction batter then the best IPS screens. Of course overall 10bit ends up being converted to 8bit because the hardware needs to support it like ATI Firepro
Now for SIPS, name me one monitor that is 6bit. The low end monitors that are 6bit are eIPS which use FRC. S-IPS is at minimum 8bit.
But we are getting off topic here..all I want to do is playback 10bit content. I am well aware of the limitations and that the decoding will be software which goes back to my question. Is the nexus powerful enough for the job.
Just tried one of the sample vids with MX and VLC. VLC was stuck on the first frame and MX played it but what seemed like 1FPS. I overclocked my phone to 1812MHz and have FrancoKernel with 512MHz GPU. Set my governor to performance and still no go. Tweaked settings on MX and still no go.
Sorry OP but I'm pretty sure the GNex can't play it.

With those Specs sounds like you're trying to cook your phone lol. Higher isn't always better. Example, I installed Batman to my Transformer which was overclocked to 1400mhz and it lagged like crazy. Once I put it down to 1100 it ran a lot better. Maybe you might have to find the sweet spot for your phone.
i just bought a Note2 but I use the phone to make 3-5h phonecall a day with clients since im self-employed and I feel that the phone is not comfortable for such long period of time for me.
Im about to return it and exchange for a Galaxy S3, but it saddens me to lose the quad core.
I bought the samsung microUSB-HDMI adapter and was wondering will the S3 be able to handle 1080p mkv with soft-encode on MX player with codecs (hard encode doesnt seems to work even on my note 2, the audio is delayed).
I just want to make sure before I do the exchange.
I have never used 1080p video but 720p video work fine in sw hw and hw+ mode for me in MX player. While traveling last week I watched 10 hours of Dexter through mlp and it was flawless.
Hi, does Xiaomi Redmi Note 5 Pro (Snapdragon 636) support hardware decoding H.265 10bit videos ?
thanks.
Yes it does.
Sure ? for a video 10bit ?
Because a Snapdragon 625 can't play HEVC 10bit video with HW decode.
ARM CPUs doesn't support hardware decoding of HEVC files. You will have to rely on software decoding.
Be careful with what you say. Technically no CPU does hardware decode of video VPUs take care of that (and GPUs but sometimes the VPU is included in the GPU as a separate sector). SoCs do hardware decode of hevc.
The Qualcomm flagship SoCs have had ten bit hardware decode since the 820. Mediatek had it on many of its chips, both flagship and mid-range (and I think low-range too) but not all of them and they stopped advertising which ones do and which don't. Kirin 960 doesn't but I don't know if the 970 does.
The mid-range Qualcomm chips are confusing. The 625 and 650 don't but the 660 does. So it should be safe to assume that anything newer above the 660 does but who knows about newer chips that are lower on the spectrum.
I know this does not answer whether the 636 supports it but it does show it's possible and we should wait for someone who can actually test it.

Yes, it is capable to. I have tried Jellyfish video, 120 Mbps 4K UHD HEVC 10 bit. This is a super deadly combo. SD636 plays it smoothly using H/W or H/W+ decoder in MX Player (1.9.24). At the 140 Mbps 4K UHD HEVC 10 bit with TrueHD 5.1 sound, only H/W+, H/W not supported (seems missing audio codec). As long as one decoder works, it is playable.
At SD625 (RN4), even the lowest 3 Mbps HD HEVC 10 bit video there, already lag and dropped to S/W, can't decode in H/W nor H/W+. This is also something that SD820 can't do in its time. SD820 is capable (hardware), but a lot of vendor messed it up and don't put the proper software/codec to decode it.
In SD636, finally we have the hardware and software/codec enough to basically decode any video. (I haven't tried 4:4:4 video though) It should hold up for quite long until the new video standard (AV1) becomes mainstream. And by that time, you probably have upgraded to newer phone.
Additional info :
Same 120 Mbps video, switch to S/W, immediately black screen. So the VPU/DSP is powerful enough, but the CPU is not capable to pull the 4K. But S/W still can play 90 Mbps FHD HEVC 10 bit, not smooth though. And you don't want to play video using S/W, it will kill your CPU and battery. (At my previous phone test, H/W or H/W+ gives 8 hours but S/W only 3 hours playtime.) I don't try any bitrate above that, since we rarely have content with such a very high bitrate. At that kind of bitrate, we would run out of storage first. (30 seconds video already 500 MB; 2 hours movie will be 120 GB!!!)
Other RN5 users are welcomed to do the test. To get the sense on whether it is smooth or lag, try the same video at other SD625/SD820 phone. Or at RN5, try FHD video below 90 Mbps and switch to S/W decoder. Other SD636 phone should be capable the same, but I only tried at RN5.
