[Nook Color General] cyberslug23:
Can't you try monitoring the CPU usage on stock and cm7 (top or similar), play a video and see if the CPU is way higher on cm7? I still see stutters on cm myself, and it would be sweet to see the video tweaked. We will also have new stuff to play with soon from B&N's froyo release. I'm guessing we will have a much easier time comparing apples to apples and diagnosing these issues if stock was 2.2 . There are a ton of factors in play (no pun intended), and we can all help by testing. It seemed like the last big jump in cm was prompted by the dude that found the video worked better with his bluetooth headset. That's the kind of thing that would take one person FOREVER to find, but amongst hundreds or thousands of testers becomes apparent. Test, and post results, and try not to be too emotionally attached to the issues. If it makes sense people will notice.... problems only arise when people start guessing, ranting, etc... (xda kids stuff) The nook is awesome and is only getting better :D
[Nook Color General] animatechnica:
i would disagree - this has more to do with what codecs/containers are being supported rather than hardware acceleration

nook color at 2.1 did play that video but it could not play other formats becuase it did not support the codecs

same with flash - nook color 2.1 played that mp4 file but take same mp4 file and wrap it in a flash container and it cannot play it
[Nook Color General] aludal:
Sure, customizations and many other improvements over "standard" CM7 ROM are welcome at any time, it's just an apparent lack of basic GPU/DSP functioning, as nemir stated, what might cause a somewhat critical attitudes. I repeat, the work of dalingrin is awesome, but there are still many questions/problems remain unresolved:

-- the "original" size of an audio "buffer" (if I get it right) was either zero, or small, or adaptive, plus small anyway. Wasn't it an indication that hardware decoding when functional didn't need any?

-- the addition of 32(?) of whatever units to that buffer brought a smoother video playback on YouTube, but can be also an indication that video playback can now easily fall back to software decoding;

-- switching the audio pipeline to push it via BT encoding might be originally either working better, or didn't need to be HW assisted at all. In any case, lipsyncing was missing, just like when the software decoding beyond bandwidth specs was involved

As for how many dudes it take to find a solution out of thousands of NC's inventive users, I'd rather try to find a real TI OMAP3/Zoom2 engineer or two who are NC owners and obviously ROFLing now seeing all these attempts at XDA Devs. In other words, they not only know the solution, it's offered in the open at their gits. It's our kernel level that cannot take it. CM7.x will be formidable when based on 2.6.36...38.
[Nook Color General] nemir:
Yeah you are right...

We must accept the lack of full potential power of NC's 2D / 3D GPU for both custom ROMs (CM and other variants) and OFFICAL STOCK ROM...

I have Archos 5 Internet Tablet which has only 256 MB RAM :) and same CPU ( 800 Mhz ) and Archos 5 Internet Tablet can play 720p .mkv .avi .mp4 .wmv files without any problem...

Moreover, Nook Color has higher RAM and can be overclocked to 1 Ghz ...

Like Archos 101 Nook Color has same GPU ...

I would prefer 800 Mhz ( maybe 1 Ghz overclocked) normal CPU with fully usable GPU ...

http://www.archos.com/products/ta/archos_101it/specs.html?country=us&lang=en

Here is the table of CPU and GPU list

http://en.wikipedia.org/wiki/Texas_Instruments_OMAP

For Nook Color:

OMAP3621	800 MHz	ARMv7	ARM Cortex-A8	PowerVR SGX530

Another information about NC

http://www.engadget.com/2010/10/28/nook-color-processor-revealed-arm-cortex-a8-based-ti-omap3621/

So Archos 101 (1024x600) can be ported to NC to utilise :cool: ...

CM7 is generic and does not utilise the power of NC's GPU ... CM7 is beneficial for bluetooth and latest android 2.3.3 ... But Arhos firmware has a better full utilised GPU driver...

Frankly, the lack of GPU can NOT be accepted. Focusing on "CPU overclock" does not make sense if you have potential of better GPU driver...
[Nook Color General] chisleu:
Cool story.

CM7 does have hardware accelerated video.

Also it is the DSP chipset which controls what formats/resolutions are acceptable, not the GPU. Ours is incapable of playing 720p video in hardware acceleration. Not to mention it's a 854x480 hardware accelerator, so 1280x720 video would be wasted anyway.

You guys are loud.

That welcome video won't play because the stock software was able to tell it to play sideways. We can't do thatyet . We CAN hardware accel videos such as this:

http://www.mediafire.com/?d42dmvva9vbigm2

You know, in 16:9 instead of 9:16?
[Nook Color General] Animec:
What would it take to get a working patch to enable 2D/3D HW acc? I mean, if the folks working on CM7 won't take the approach you mention.
[Nook Color General] poofyhairguy:
That link tells you right there why we can't play 720p but the Archoses can:

OMAP3621 vs OMAP3630

They have a better DSP processor.

The GPU and the DSP of the Nook Color work fine in CM7. We are able to play games just as well as rooted stock does, and videos I have encoded that maxed the rooted stock (as it had as high of a bit-rate as I could get without frameskipping) still play fine using Vital player on CM7.

As chisleu stated its not perfect, but its certainly working because the Nook Color's CPU can't even come close to playing my files.
[Nook Color General] nemir:
Overclocking NC to 1 or 1.1 Ghz should give same performance as Archos's...

By the way, Motorola DEFY has 3610 GPU but it can plays 720p files by means of changing lib files :cool: ...

http://xdaforums.com/showthread.php?t=935017

We can try this method to our NC to play 720p movies :) ...

As I said before latest stock NC has more recent builds in lib folder. CW RC4 uses old lib files...

Anyone can compare and see the difference between latest stock ROM and latest CW R4... CW R4 does not update latest official files from lib (its sub folders and files too)
[Nook Color General] animatechnica:
hey nemir how bout taking us to solution space
[Nook Color General] Canadoc:
Maybe you could try to copy over those lib files and see if it works? If it does then maybe cm7 devswill port it.

From 1.1 Nook Color with 1.1 ghz overclock
[Nook Color General] aludal:
That link mentions (quite vaguely) where variants of the same silicon (IVA2) are different:

It is worth mentioning that encoding a (mp4) video is several times harder computational task than decoding it (as in playback). Sure I'm glad and happy for all owners of OMAP3 based smartphones with cameras which can record 720p, or 480p, or 360p or any medium to high bitrate video with their devices -- thanks to DSP HW acceleration of encoding process.

Now, (mp4) video decoding routine is much simpler process, and most important, it doesn't exactly use the same circuitry (the proof is in the possibility of live view while video is recorded on a given OMAP3-based device.) Sure, it doesn't conclusively prove anything, and TI engineers were not exactly helpful in detailing the 3621 IVA2 specs. But in my blog I was writing back in January/February on how smooth Evo's YouTube HQ could play clips searched out by "1080p" "Full HD" "IMAX" and the like keywords. Today, it struggles (loses frames), or refuses to play them.

The adequacy of hardware decoding of at least 480p/720p mp4 on NC was proven back then. Sure, that was Eclair back then, and AOSP 2.3 has NEON framework/hardware Stagefright pipeline broken/unimplemented since -- probably in expectation of Renderscript of Android 3.0 (or 2.4), I don't know

Out of my years (2004 or so) of struggle with mpeg2/mpeg4 decoding of 1080i satellite streams I was of conviction that in HD video rendering the major computational task is a scaling, deinterlacing overlay: once you don't have it in your hardware (shaders of GPU: SGX530 in our case), you have a stuttering, A/V desynced video -- or no video at all. Sure, it was outdated DirectX games back then, but anyway.

[G Tablet Q&A, Help & Troubleshooting] ssummerlin:
Hello. Excellent work you are doing here.

I received my Woot Viewsonic gtab yesterday and have been rooting and modding and doing a lot of side loading.

I didn't care all that much for the stock OS just as everyone else has said and I decided to go with TNT lite 4.3.

Everything works great. I didn't even have to patch MarketPlace.

I did notice that after the mod, my hard button HOME key no longer responds. The soft button key HOME works fine. If you are in a app that covers up the soft key, you cannot go straight to home. I almost got stuck in Angry Birds, but just backed out.

If I boot up into ClockWork mod, the hard home key works fine. Did I miss a patch for that issue?

Flash seems to work fine also. Are there any other mods to apply?

Thanks for your help and all of the info you provided in the threads.

Steve.

[Nook Color General] al2x:
Can someone please explain to me the proper steps from point A to point B?

What I did was used an auto-nootered 1.01 B&N Stock rom, i downloaded an EXT-4 compatable CWR (updated it to 3.0.1 also) and then flashed CM7 (formatting system, cache) and I'm stuck in a boot loop...

I had CM7 working awesome the other day, but I guess it didn't support busybox when I installed it because then my nook stopped booting/freezing after a boot.

Can someone just create a real simple flow-chart of what I have to do? Thanks
[Nook Color General] al2x:
Oh and I want to install it to the eMMC as well, although I have a class 6 sdcard I'd just much rather know its sitting on my internal and as fast as possible :)

Al2x,

This is what I did on my NC.

Downloaded the BOOT Only from this thread " http://xdaforums.com/showthread.php?t=914690 "

http://www.etoile-laconnex.com/CWR-removal.zip

Downloaded CM7 RC4.

Boot to CWM 3.0.1.0, format Boot, System, Data and Cache.

Turn off the NC, boot to CWM 3.0.1.0 again, flash the BOOT file, then flash with CM7 RC4. I also did downloaded the GAPPS and flash that as well.

Reboot, back in the game.

Hope that would help.

[Nook Color General] al2x:
that seems pretty logical. what I just did was basically nootered stock 1.01 and then downloaded EXT4 bootable CWR 3.0.1.0 and formatted system, data, cache, battery stats & dalvik, and didn't touch boot.

It boots up into CM7 just fine, the only thing I've noticed is that I guess not formatting boot leaves the "power of reading" B&N boot screen up, which I don't mind at all, I used to have a nasty pixelated "LOADING" splash come up. Anyways, thanks for the help, I think I might be fine (knocks on wood) :)

Hi guys i have an evo and im running a cm7 rom and my kernel is savaged-zen 1.0.1 nosbc bfs.

Today i tested my phone to see how long it would last me on a normal day, i played games for about 4 hours or so (class), i txted throughout the day, did about three 5 minute phone calls, changed the brightness of my phone throughout the day depending on where i was but mainly kept it dim or at 25%, i used many apps in and out for different things and i used my internet for maybe an hour and a half.

My Cpu setting are:

Governor: SavagedZen

Min Cpu frequency: 128MHz

Max Cpu frequency: 1190MHz

[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
http://xdaforums.com/showthread.php?t=894880

The main difference is that sbc kernels implore the trickle charge, which slowly pushes voltages onto your battery [requires longer charging] but holds the 100% battery a lot longer and over longer battery life; but there are reports of the kernel causing the battery to melt, exploded, ect because charging the battery that much is dangerous for the battery and can do long term damage to the battery. The non sbc kernel just doesn't have that mod.
[EVO 4G Q&A, Help & Troubleshooting] Batman58:
That's good battery, no doubt, but your display is 4% and the OP's display is 18%.

He's using his phone much more..

To the Op. It looks like you actually use your phone and not let it sit idle.. so yes that is actually decent battery life for as much use as you got out of it. No matter what people tell you, you aren't going to get over a day on one charge if you use your phone that much. Anyone can get a day+ if they let their phone sit idle.. hell sometimes I don't use mine and easily get a day in a half.

Once you actually start using it, the battery is going to drain quick.
[EVO 4G Q&A, Help & Troubleshooting] Green_Arrow:
sbc lets u have more battery life, but it's like pushing your battery to the limit so at some point your battery will just end up being horrible.

THANKS..... Green_Arrow...teh roxxorz.......i never even knew that....ive been using SBC for wuite a while now upon someone elses recommendation and its been great....but i never knew that it put strain on the battery.....ive noticed wiht some ROMs how u take the battery off the charger and 10 percent is gone instantly LOL....thanks alot guys....thats clears it up for me in a BIG way.....

P.S.......but in terms of battery life......do u get the same battery life from 2 of the same KERNELS weither they are NON-SBC..or SBC?
[EVO 4G Q&A, Help & Troubleshooting] Green_Arrow:
np, and battery life is kind of the same, remeber sbc allows your battery to have more charge it just turns your battery to garbage later but the drain rate for both should be the same unless your using sbc then when your battery goes bad then it'll drain fast
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
In a technicality, sbc will give you longer charge, because it holds it longer. That is why in some roms [depending on the kernel] you drop that 10% in minutes, because the battery isn't meant to hold that "full" charge, because its damaging. On CM7 with the non-sbc Tiamat kernel, within 1 hour, I'm still in the mid to low 90's.
[EVO 4G Q&A, Help & Troubleshooting] Green_Arrow:
that's exactly how my evo is
[EVO 4G Q&A, Help & Troubleshooting] teh roxxorz:
That's how it'll be if you aren't on an sbc kernel. The regular Tiamat kernel lets me stay in the 90% range for 1-2 hours off the charger.

TNT Lite 4.3 works great but I noticed afterwards I occasionally encounter a power-on issue. <insert joke here>

If I power down normally using the power switch, when I go to to reapply power the unit wont come on until after about 1 minute or two.

The gtab acts like the battery went dead but it will power-up after a couple minutes. It does not happen every time but it usually happens when I want to demo the unit. The unit can stay on for a long length of time or short. Can really figure it out.

I did not have the unit log enough on the stock rom to notice.

The sleep function built into CM7 in the Notification Power Widget however sleeps the device immediately.
