Just making sure I'm not missing something...

The thread header says 2nd public release:

[ROM] CM7 Alpha for the Nook Tablet 2nd public release Version Alpha12 Feb 19th

But the downloaded file says Public 1:

CM7_NT_Alpha12_Public1.zip

Is that wrong - or is the 2nd public release counting the release a couple of weeks ago? Just asking to make sure I have the latest and greatest and that was slightly confusing.
[Barnes & Noble Nook Tablet] albertwertz:
Installation video and slight demo for OP if you like. http://www.youtube.com/watch?v=8QQ8mkfw8q8
[Barnes & Noble Nook Tablet] Mike_IronFist:
This is the first public release of Alpha 12. The previous release was a different Alpha number. (I think it was 8.)

Another video showing the advantages and disadvantages of using this rom at the moment. It really is working quite nicely. Only one item is having problems that I can tell. Shown in the video at the end. http://www.youtube.com/watch?v=PTWWV3ckjxM
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Thanks albert but I think you really should have only posted that in the questions and feedback thread not here in the development thread. aLthough I suppose it does give people an idea of wether thye actually want to use CM7...

Hmm....

Video Hardware Decoding

I'm trying to fix the video decoding issue and have done a bit of research. We know that graphics acceleration has been enabled and is working for games and the like but video streams do not seem to be getting access to the graphics chip.

I think the key lies in this site:

http://omappedia.org/wiki/V4L2-GFX

We already have the gfx_vout_mod.ko built and insmoded but maybe we need to try and get V4L2-GFX loaded into the kernel.

I've activated a 2nd video framebuffer in the kernel which seems to help and should support a few more apps, but have not been able to determine if V4L2-GFX is being properly used or not.

EDIT: The more I think about it (which can be dangerous) this should be built within the kernel. Going to rebuild tonight and test ;)
[Barnes & Noble Nook Tablet] CelticWebSolutions:
You beat me too it! I was going to suggest including it IN the kernel. I'm sure I read fattire Suggesting exactly that in the 3.0 kernel thread too :)

Chop chop! Get on with it man, if you don't do it now and fix this within 30secs I'm dropping this crap Rom and going back to stock!
[Barnes & Noble Nook Tablet] Goncezilla:
30 seconds must be a lot longer in European units, cause I got 5 US hours before I can get to my dev machine ;)

I'm hoping the fix is as easy as fliping the kernel switch from 'M' to 'y' but I have a feeling we still need to point CM7 to the /dev/video100 device for hardware decoding. That might be trickier to figure out.

Anyway, crossing my fingers that a simple kernel change will fix it!
[Barnes & Noble Nook Tablet] Mike_IronFist:
Speaking of modified builds, are you guys gonna release the source code for this release?

I know it sounds bit crazy considering how tightly you kept the ROM distribution at first, but I think the benefits far outweight the risks. Consider how much easier it would be to squash bugs when there's more than 3 guys able to submit patches.

It's also important to note that the Cyanogenmod wiki's Unofficial Ports section won't allow ROMs to be listed without source, since they take that kind of stuff very seriously.

I know that what I'm proposing is a pretty radical shift in your current development model but wide open development models are almost always more effective than restricting everything to a small team.

Edit: Hope that didn't sound too preachy! D:
[Barnes & Noble Nook Tablet] Goncezilla:
The 'source' for this has always been posted. Please look here:

http://xdaforums.com/showpost.php?p=21819860&postcount=2

I will appologize for not keeping this up to date by the second (lots of builing going on and it is too much work to repost everything we touch every time we try something new), but I am keeping up with this and plan on posting more this evening.

This isn't really source here since we have been using the standard B&N 1.4.1 and Kindle Fire 6.2 source that we got off of thier respected websites. We eventually will need to modify source to get things like 5 finger input working, and we will setup gits when that time comes.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
radical shift? No not at all. Like Gonc has already said the main source has always been available, it;s just the B&N kernel mixed with modified NC CM7 system and ramdisk.

What we have been keeping tightly to our selves was the compiled versions after the first release that actually turned out to be dangerous. As you know the only reason for that was that we wanted to guarantee as much as we could that it was safe for just about anybody to use.

Putting it bluntly, many members on here do not read, that has been shown time and time again with people asking about things that have been answered/discovered numerous times before (did we mention the source has always been available? lol). They also post in threads where clearly it has been requested that they do not.

So due to this inability we didn't want to release a version that was potentially unsafe, Alpha or not people take very little notice of warnings and just stick it on and make a nice paper weight of their device by not following instruction and then come on crying that they've 'bricked it'.

We have no problem at all with people using the available source code, we've never said no to that, we just said no to people having unfinished untested builds from that source code.
[Barnes & Noble Nook Tablet] Mike_IronFist:
Sorry, I meant the latest source code - I was aware of that post with the various source links in it, but it apparently hasn't been updated in 2 weeks. What Gonce said about setting up Git repos cleared that up though.

I mean no disrespect...sorry if it came off that way. I know it's frustrating when you're putting so much work into this project and random people just come along and start demanding stuff.
[Barnes & Noble Nook Tablet] Goncezilla:
No worries Mike. We have more of a port than a build per-se, but promise we don't have any custom source code. If you have any specific questions as to what source was used where let me know, but basically the B&N code was used for kernel and gfx, Kindle Fire was used for wifi. The base system was built from a mix of Kindle Fire and Nook Color CM7 files as well as some from the Stock B&N Rom.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Wasn't taken as disrespect at all ;)

I should have explained more in depth like Gonc has above ;) Fell free to contact either of us directly if you need to know anything specific ;)

We've asked in the original thread for people not to use our build to base any others on just yet (only for a very short while) and I'm sure everyone will respect that request. Then once everything is as we'd like (updated to latest version on CM7 too) we'll post up a sort of how to for it all with all the links for everything and then everyone can start making modified versions will all manor of useful (and probably not so useful) stuff :)

You know you can PM me with any questions you have and I'll answer ;)
[Barnes & Noble Nook Tablet] Goncezilla:
I know its not cool to quote yourself, but I tried simply loading the gfx driver into the kernel and it did not fix anything :(

I was able to recognize and chmod the stream buffer easier though (/dev/video100) and performance SEEMS to be a tiny bit improved. Still no hardware decoder support though.

My next step is to try and rebuild gstream and make sure it points to /dev/video100.

From the research I have done, the OMAP4430 is only supporting H246, MKV, and JPEG video codecs right now. What baffles me is how the stock ROM was able to 'hardware' decode other files.
[Barnes & Noble Nook Tablet] admiralspark:
Just out of curiosity...are you sure it wasn't software decoding through a proprietary "decoder" or interpreter? The reason I ask is that it sounds like the requisite codec's appear to not be interacting with the video driver...if you have HW acceleration with games, you will be able to use it with video players (even streams)--you might just need pointers to the proper driver sections and calls. I'll snoop around the source and see what I can see tonight, we've dealt with the same kinds of issues with intel's i915 drivers in the past.

EDIT: Is there some way to get a live update of system resource usage to see if the hardware is experiencing load when streaming?

EDIT2: Wait, this module is being built as a module at kernel compilation time right?
[Barnes & Noble Nook Tablet] :
I am not entirely sure if this is a system/kernel issue, but i have been unable to restore any system apps through titanium backup, even though i can restore user apps. Thought you devs should know.

Viel gluck!

Sent from my TARDIS.
[Barnes & Noble Nook Tablet] ms2003:
if system app have additional lib files, it may fail, if only single app, it will work.

I think it's titian backup issue, not related to kernel.
[Barnes & Noble Nook Tablet] Goncezilla:
Thanks for looking into this.

The Alpha release that is out there has a module for the video buffering GFX. I'm working a new build where I have included the video buffering acceleration driver into the kernel but still have no luck getting hardware decoding to work.

What is different between using the module and wrapping the driver into the kernel is that the buffering device, /dev/video100, is available at boot.

I think you are correct in that we need to find and change the hardware decoder pointer that will reference /dev/video100. From what I can see the only way to do that is either build CM7 from source (we have just ported other CM7 builds at this pont) or find an OMAP4430 (Kindle Fire?) CM7 build that has video acceleration enabled and port the necessary files.
[Barnes & Noble Nook Tablet] Mike_IronFist:
Interesting. Access to /dev/video100 might be why the stock ROM plays Netflix videos at a higher resolution and with better audio sync than the current CM7 build.

As for porting from a build that has video acceleration? Well, I did some digging, and there seems to be way too many varieties of CM7 ROMs floating around for the Kindle Fire, and none of them seem to be that well-documented in the dev forum for it. It's unclear if they've got perfect video acceleration or not, and efforts are concentrated on getting CM9 to run well on the Fire instead. Building CM7 from source seems like the sure bet.
[Barnes & Noble Nook Tablet] Goncezilla:
Kinda what I'm seeing too :( Unfortunately building from source would require a bit of work to get a good BoardConfig file made. I suspect the CM9 team already has one but I don't have access to it. Planning on starting work on it eventually but I don't have the time available that I did when I first started porting.
[Barnes & Noble Nook Tablet] Swiissjokr:
Very big annoying bug. When you go to YouTube after i finish watching a video , When you're in landscape and you switch it to vertical your phone screen goes black, And then you have to reset holding down the power button for 10 seconds and turn it back on.
[Barnes & Noble Nook Tablet] Know-Fear:
If you haven't come up with a fix for this, then I suggest you take it to the freakin' support thread. Please learn to read.
[Barnes & Noble Nook Tablet] SilentStormer:
Yeah definately a support thread question. Weird because ive never seen this issue on mine :/
[Barnes & Noble Nook Tablet] iCE-dOGG:
All the files I have played mkvs, and other h264 content worked with HW decoding, anything compressed using divx, xvid, etc failed back to software decoding in the stock ROM. With this ROM using MX player everything fails back to SW decoding.
[Barnes & Noble Nook Tablet] Goncezilla:
Ok this is what I thought should be happening. We know that the codecs are not being properly utilized in CM7 yet so no hardware decoding is working.

Thanks for clearing up the fact that not all videos were hardware decoded in stock. Some of the posts I was looking at suggested they were, yet everything I was looking at suggested only H264 and MKV would be supported.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
we are working on getting full gfx acceleration and decoding working and are having good results, it may be a little while before we release a working build of it yet though.
[Barnes & Noble Nook Tablet] SilentStormer:
This really belongs in the cm7 SUPPORT thread (NT forums> NT general> cm7 support thread)

Attached two log files from dmesg regarding wifi disconnecting. Had a particularly bad issue today where it was just constant disconnect/reconnect. Even turning off wifi and restarting the NT was not fixing it. Had to reflash.
[Barnes & Noble Nook Tablet] succulent:
Here's preview of HW decoding. It's working great. Screenshot doesn't take screencap of the video, but the video is playing with audio in sync in 1080p. HW accelerate is working. I'll have gonz look into this. I'll post youtube video later.

Before posting in this thread, ask yourself:

Is what I'm about to post a bug about the rom?

Is what I'm about to post a thank you to the developer?

Is what I'm about to post a +1?

Is what I'm about to post a quote to another post talking about this [insert your problem here] not working?

If you answered yes to any of the above questions you are in the wrong dammed thread! Use the blasted

Support

thread for this!

On another note... What's the point of having this thread? Why not just allow the first 3 or so post from the developer and then close the thread? Point all questions to the support thread.
[Barnes & Noble Nook Tablet] TRS-80:
Because there is still development going on (getting hw acceleration working, etc...).
[Barnes & Noble Nook Tablet] dkb218:
Gee, really? Well then only developers should be given access to this thread. All others should post in Support thread.
[Barnes & Noble Nook Tablet] nba1341:
or people should just follow directions? what if a new dev wants to come and help seems like a hassle to close off the thread. it's pretty clear in big bold letters to post in support thread.

[Barnes & Noble Nook Tablet] CelticWebSolutions:
Looks like you beat us to posting about having got HW decoding working! WE managed to get it running over the weekend and as you say even 1080p seems to work flawlessly with proper audio sync.

I must be honest I didn't realise that the video that had been playing on the NT was so poor until I saw it running with full HW decoding and acceleration on the weekend. It really is a huge improvement. It's not quite ready for any kind of testing yet but it will of course be in our next available build :)

When you are around next drop me a PM or catch me in IRC for a quick chat ;)

Keep up the good work!
[Barnes & Noble Nook Tablet] GeekyMaestro:
To me this is a huge step forward in the development process. Beyond the fact that it makes video look pretty, it utilizes the available hardware in a way the original (and for that matter even rooted) ROM could not/would not. I know there has been discussion regarding enabling bluetooth for peripherals, but from the documentation I've seen, there's nothing stating that bluetooth hardware actually exists in the NT. We all can hope. Good work on getting the hw acceleration properly utilized. We're all looking forward to future updates.
[Barnes & Noble Nook Tablet] dhkr234:
Components on these things are modular. If you need a part with one of two functions, you buy the part that has both. Bluetooth is typically on the same chip as 802.11 since they share the same frequencies -- 2.4 GHz. As it happens, this device has the TI WL1273: http://www.ti.com/general/docs/wtbu...3&DCMP=wtbu_connectivity&HQS=Other+OT+wilink6

As it turns out, 802.11 a,b,g,n, bluetooth, ANT, FM rx, and even FM tx :eek:

FM already exist in the chip, but it can be not connected, you need to see on the schematics to check (we have same case in motorola milestone/droid/etc).

CM7.2 Update [Spilling the Beans]

Sorry if its been a while, but I have been away for work.....but Team B has been busy :D

[Barnes & Noble Nook Tablet] sprintrjm:
re

Yey team b.

Hardware video playback hooorah.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Quick update for everyone so you know whats going on.

I previously mentioned an overclock update, this was a modular update which we had tested and worked fine but you had no real control over it as such, it was either on or off. We've recently had another member join the testing team and it appears they've been working on a kernel with proper governors for overclocking. So we're pretty much thinking we'll not bother releasing the module version and will wait till the proper kernel version is available for us to compile and add as an extra download for everyone.

Goncezilla and myself have not been working quite so much on CM7 lately as we had to catch up with real life but we got back to work over the last few days and there is now a brand new version in testing and so far it is doing very well with some great feedback.

We've listened to what people have said and hopefully this new version will make a few more people happy with their NT.

When our new version is released we'll release an SD boot version at the same time which is also in testing and does of course work on the 8gb too :)

The new version is the latest CM7 available form source and has been a complete rebuild.

So watch this space, it's coming soon!

Before anybody asks for an ETA, 2 weeks lol

Will this update fix the ADW Launcher lag? (when opening app drawer)
[Barnes & Noble Nook Tablet] Goncezilla:
I'm not familiar with much of a lag in the last build, but there doesn't appear to be any real lag in this build.

There is an affect when oppening the app drawer though. You can adjust the delay in opening or disable the effect all together in the settings.
[Barnes & Noble Nook Tablet] Excessiveidling:
If you experience laH with adw why not just switch launches? I use go launcher ex and it works fine
[Barnes & Noble Nook Tablet] ElectroMike:
When guys, when ??!! :-)
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Now the strange thing is that’s where I originally had some lag so went back to ADW again. Like Goncezilla said though I can't say I can notice ANY lag on the app drawer in this build, it might be caused by having an extremely large number of apps in your app drawer mind you.

2 weeks :)

Posts like this make me hope for never.
[Barnes & Noble Nook Tablet] dhkr234:
Nah. Posts asking for scheduling indicate that the users are eager for it. It should be taken as the HIGHEST PRAISE and a sign of RESPECT.
[Barnes & Noble Nook Tablet] GeekyMaestro:
What irritates me is the simple lack of reading comprehension. The release date for the build was already said (if I'm not mistaken) and frankly I don't think anyone should have to post it again. Go back to the announcement from Celtic and read it your darn self. I welcome enthusiasm, but can not tolerate willful ignorance.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
It does begin to bug me to be honest, the simplest rule says do not ask for ETA's

So no matter when they ask it will be two weeks...

If they then reply with something stupid like "Great! I can't wait" then it just proves they haven't read any previous posts!
[Barnes & Noble Nook Tablet] Cubanluke88:
Just start saying never. Also indicate that you will continue development but only be sharing it with the inner circle.

Also, ban people that ask for etas.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Due to popular demand I've just posted up and SD version of CM7.

The new internal version will follow along soon :)

And due to so many people asking here are 2 update zips to enable / disable an overclock of 1180Mhz. You cannot control this with standard overclock software. you either install it or uninstall it. On or off!

It's a conservative overclock for safety but pf course you are still risking your device by overclocking it.

THIS COULD DAMAGE YOUR DEVICE. YOU USE THE OVERCLOCK AT YOUR OWN RISK!

Download overclock updates HERE

The zip contains 2 updates flashable via CWM, one to enable and one to disable overclock. THIS IS PROVIDED AS IS AND WITH NO SUPPORT
[Barnes & Noble Nook Tablet] lavero.burgos:
Does this new SDcard version contains the new build of CM7 or its still Alpha12, 'cause the zip says Alpha_final?

Thanks for this. Wonderful job :)

[Barnes & Noble Nook Tablet] CelticWebSolutions:
You can now use the rom for your own releases :)
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Oh and totally against the tradition of XDA developing.

I can tell you when the new internal version will be released, theoretically I could have released it with the SD version but due to CM9 having just had an alpha release I thought I'd wait a day or so before releasing our new version ;)

So just to give you all something to look forward to, the new internal version of CM7 7.2 will be released for you all to play with before the weekend.

OP states not to use it for your own build yet though! I'll keep saying it then there are no excuses for not taking notice of it and you can't complain when your post of a modified full version of the rom is removed.
[Barnes & Noble Nook Tablet] camapghe:
Just a little tiny request to CelticWebSolutions if you can theme it to ICS theme, or guide me how to, will be much appreciated.

Good day - just a question - the OP has a link to INTERNAL still - I'm assuming that link is the "older" version. If so, and I didn't read these past few posts, I might have downloaded it instead.

Is that the case?
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Yes it's the alpha 12 version that has been released a few weeks. It's safe enough to use though just has a few minor issues :)
