Before I knew about the NC, I had been looking at the Galaxy Tab. I am only interested in 7" tablets, no bigger. But the $250 NC was an impulse buy for the price. I didn't know about the deals to get it cheaper.

Video is really not a concern for me. I am disappointed by the noisy headphone Jack though. I also think the slowness of the stock browser is an embarrassment frankly. An OS in 2011 without quality GUI acceleration? How Google can be proud of that is beyond me.
[Nook Color General] dalingrin:
A few notes:

Neon, while faster than scalar video processing is not a real subsititute for a DSP. NEON adds large vector registers and ALUs but doesn't duplicate the entire pipeline. The DSP on the other hand is an entirely separate execution engine that frees the CPU to do other things.

NEON wasn't removed from Android 3.0. Its just not supported on current Honeycomb hardware because the Tegra 2 doesn't have NEON. As of the Cortex A9, ARM has made the NEON simd engine optional. It accounts for roughly 15% of the SOC die space so including it is not trivial. NVIDIA is adding NEON in Tegra 3 though.

720P codec support requires a 1ghz processor and an 800mhz DSP. This is the only real hardware requirement that the Nook doesn't have. We can easily overclock the CPU and DSP to meet these requirements though. Unfortunately, it seems unlikely that B&N will purchase licenses for 720p codecs given that we don't have official hardware support.

The new Ti DVSDK has some 720p codec support. I would like to try to use it for the Nook at some point. I think it will be difficult because the DVSDK only supports Linux and is very different from the OMX codecs that we currently use. The Rowboat project uses the DVSDK for android so it should at least be possible. I do think it requires us to change quite a few components though.
[Nook Color General] a.fenderson:
I've tried the iPad, and I think the 7" formfactor is more appealing to me. I might consider the Galaxy Tab if my budget were that high, but I think the NC will be a great starter tablet for me, then I'll save up to get a nice 1280x720p or higher AMOLED pad in the future. :)

I hadn't really heard much about this, how loud and persistent is the headphone jack's noise?

Interesting. In my noobish naivete, I assumed that the limits of the DSP's video decode might be either hard-baked in the worst case or merely clock-/bandwidth-limited in the best, but you seem to be saying that, given the proper software support and the necessary (and do-able) CPU & DSP overclocks on the Nook, that full/proper support for hardware-accelerated H.264 decode could essentially be enabled at the 720p level; is my understanding correct?
[Nook Color General] Divine_Madcat:
Well, i have to admit, from a chip manufacturing prospective, it makes sense. That would mean the 3620, 3621, and 3630 would all be the same die, with the x30 getting the best silicon that can scale the highest frequencies. From the marketing, i had believed that the DSP was actually different, but if speed is the only difference, then I will hold hope.
[Nook Color General] swaaye:
It is quite poor with a lot of hiss and some distortion of certain frequencies. It is adequate in a noisy situation but for quiet listening it is a disappointment. It is reminiscent of poor integrated PC audio.
[Nook Color General] swapdotavi:
Yeah it's very noticeable at home, but out in public it's just fine IMO. I heard that the new CM7 builds improve the quality a bit. Can anyone confirm that?

M-JPEG Update and recap

So far, we've got:

1. This 1024x600 MJEG video @ 24 fps, 1-minute clip, 125 MB, playing seemingly flawlessly, with reportedly excellent video quality and working audio, for anyone interested. Video bitrate is very high @ 17.4 Mbps.

2.

(Untested--any volunteers?):

This untested 1024x600 MJPEG video @ 30 fps, 69 seconds, 213 MB. Video bitrate: 25.4 Mbps. It's not super quality (source limitation only--still encoded with quantizer 1 in Xvid4PSP), but another proof-of-concept test: 24fps is working, so I'm trying to find the upper bounds on the framerate for flawless MJPEG playback. Audio on this one is 192 kbps, 48 KHz MP3, so in some cases, you may need the ALSA update, which appears to be stable, to get it to work w/o stutter etc (someone please correct me if I'm wrong on this or have misunderstood).

3. 1024x600 MJPEG @ 60 (59.94) fps:

So far, Xvid4PSP is causing strange encoding artifacts in my high-res 60fps file conversion attempts, so that's still on hold pending finding another easy-to-use MJPEG encoder GUI or a workaround. I still don't know if the NC screen even supports 60 fps refresh, but if it does and we can get video-based sources to play at native resolution and >= 45 fps, this should look crazy awesome.

@cowballz69: are you still interested in a detailed walk-through on encoding 1024x600 MJPEG videos? It's already simpler, I believe, since the recent fixes to audio don't require the extra downsampling step. If anyone's interested in the written walk-through for going from single-M2TS Blu-ray rip (or MKV should work) to 1024x600 MJPEG, then let me know and I'll churn it out.

The encoder I used (RER Video Converter in conjunction with a simple AVS script) didn't allow me to specify a quantizer, just "same quality as original," whatever that means (the original was pretty excellent quality). RER Video Converter seems kinda buggy--it crashed on me more times than it worked.

Some kind soul please try one or both of these out and let me know if it looks like it's playing back @ high-motion speeds (w/ super-smooth, "real-life" / high-speed-video look). Thanks!
[Nook Color General] swaaye:
My use is all CM7 and it's definitely noisy there too. Also get the occasional stutter/pop/screach if I do any multitasking. The hiss is most likely in the hardware itself. Poor electrical isolation.
[Nook Color General] chisleu:
If the issue with the new kernel is fixed, we will be able to play 720 video in moboplayer.

It can actually play right now, once. but then you have to reboot.

Wow 60fps is a little crazy! :)

I'm encoding 3400kbps 1024x580something insidious trailer.

Not a great movie btw. creepy, scary, kinda weak.

It didn't play the first time. rebooting to be sure it's just not bugging. (edit: nope. 3400 isn't going to fly. going to try a 2k)

The lower bitrate 1024 works fine (rf:18, still high quality. circa 800kbps)

Mobo SAYS these are playing in hardware. maybe they are and maybe they aren't... maybe it's only accelerating part of it in hardware.
[Nook Color General] a.fenderson:
Do you mean that there's a known (and known-to-be fixable) issue that once resolved will definitely enable full 1280x720p playback?

60fps is crazy as in awesome, and worked on yours, or crazy ambitious, as in it didn't and/or not worth trying? ;) Now that I've got my Nook, I tried it, and it's tries to play without frame-dropping, so it's way slow, but I'm not running a current nightly and I haven't messed with any OC settings yet.

Here's a 30fps MJPEG clip, 170MB, 49 seconds. It plays fairly well for me in Moboplayer, and looks really nice. Something happened during encode to add pillarboxes on the sides, oddly--it was a true 16:9 source downscaled to 1024x600 in AVISynth prior to RER Video Converter's encode.
[Nook Color General] Divine_Madcat:
The post you quoted refered to the play a video once then crash bug, that is fixed with Dalingrin's latest 4-18c kernel. As it is, nothing has really changed. Mobo player is able to play many of these higher resolution videos very well, thanks to the Arm NEON extentions (i guess since it can use these, it calls the player hardware, which technically isn't wrong...).
[Nook Color General] :
All sorts of interested :D
[Nook Color General] a.fenderson:
Cool, thanks for the clarification.

OK, walk-through will be up tonight or sometime tomorrow.

Here's a version of the same clip I last posted, @ 30fps, but encoded in Xvid4PSP, and it didn't fudge the AR. 174 MB, still 49 seconds. As before, no audio on this one. MJPEG quantizer was set to 1, downscaling from 1280x720p (bicubic), alternate frame selection, and fps adjust via AviSynth script.
[Nook Color General] skwalas:
I wonder what you're doing differently... I've ripped at RF16, RF10, even RF6 and gotten playback just fine in both mobo and stock players (all off 720x480 dvds). Can't say it seems to be anything to do with bitrate, unless you've tweaked something else in a not-so-good way? At RF10, if I recall, bitrate was ~3900kbps (it's been a few days and too many different setting tweaks to remember clearly).
[Nook Color General] Cybore:
@a.fenderson

Thanks for the writeup. I gave your tutorial a go and I must say I'm quite impressed at how good the file outputted turned out. I've played with various programs and different encoding settings and I must say that nothing compares in terms of quality. The only downside as you mentioned, is that the file resulted from the conversion process is Huge. For one of the videos I converted, file size was around 2.3MB per second; no joke when you said dump to 32GB microsd.
[Nook Color General] a.fenderson:
Yeah, the bitrates are comparable to Blu-ray. And for some reason, even though I'm now experimenting with fully hardware-decoded H264 @ ~854x480, which can look really good upscaled on the NC if encoded with proper settings, I can't seem to get any file over 2GB to open. The only hard limit I know of is that the SD can't even hold files over 4GB since the cards are formatted FAT32, but there seems to be something else preventing me from opening files over approximately 2GB--the stock player and Moboplayer can't even try to play the video because the files just can't open. I've asked about this elsewhere as I couldn't find anyone else complaining of this, but so far no replies.
[Nook Color General] carlosraf20:
I have install Moboplayer from the market and there is this codecs ARMV7VFP3,

ARM V7VFP,and some other but those are not ARM v7... and in the mobo website it has a download link for ARM V7_VFPV3, ARM V7_NEON .... what is the codec that I should be using the NEON from the website or one from the market. I have been using rockplayer and it has been getting the job done. btw I have CM7.0.3 with the OC kernel at 1300
[Nook Color General] a.fenderson:
There's been some confusion about that with others and myself as well, but the ARM V7 NEON one is supposedly the correct one. I manually installed it from the dev's site, but off-hand it didn't seem to make any noticeable difference--not that I've thoroughly tested.
[Nook Color General] carlosraf20:
Ok then i will try out the neon one from their website.

Thanks
[Nook Color General] Cybore:
Do you mean mp4 hardware supported videos over 2gb? Because I encoded a file (about 2.2GB) with the settings above and was able to open it just fine. There's some very minor lag, but for the most part video was fairly smooth.
[Nook Color General] a.fenderson:
Yeah, I encoded to H264/AVC with settings that have worked just fine for short clips, but there's some file-size cutoff point on my NC around (but maybe a little over) 2 GB where the file just won't open at all, Moboplayer reports "couldn't open" or something, I'm not sure of the exact wording. This happens for harware or software decode modes, and I know it's not caused by the content being unplayable because if the file is at all readable Mobo always at least tries to play it, even if it chokes big time and can only display a frame or two. I haven't actually tried an MJPEG file of say around 2.5 GB--I guess I should.
[Atrix 4G General] crea78:
I accidentally hit "ringtone" notification sound as default and not sure how to go back so I can use my personal music as a ringtone. Does anyone know how to reset this... thanks
[G2 and Desire Z Accessories] Lord Bodak:
Having used a TPU case on my E71 for the last two years, I've already ordered one for my new Desire Z. Now I'd like to find a leather case with a belt clip (preferably horizontal) that will hold the whole package. Does anybody have any recommendations?

Also, I saw mentioned in a few threads that a magnetic closure on the case can cause problems (potentially long-term) with the compass? Is there any truth to that? If so, I guess I want a case with no magnetic closure!
[Windows Phone 7 General] alexander555:
Hi,

I've two questions.

1. Which navigation sofware can I use offline with phone 7 (alternative to the t-mobile dongle).

2. Which smartphoneholder is good for using in Car. Im looking for a aktive solution so that it's not nessesary to plug in cable in the smartphone if i plug in the phone (same principle as the becker navigation holder)

Thanks for your feedback
[Windows Phone 7 General] agp64:
Well I have given up on Getting any GPS software for WP7 and use a Dedicated GPS for all my Navigation in Malaysia and Singapore. There is no company supporting WP7 for of line use of GPS maps that I could find.:(

If you purchase a dedicated GPS unit with Bluetooth it is possible to use it as A hands free device as well. Most dedicated units also come with a mount.

I have a Nokia phone that I use for GPS when traveling as all the maps and turn by turn navigation are free.:)
[Windows Phone 7 General] randude:
I'm using the AT&T Navigator software on my AT&T focus and its turn by turn directions work great. It cost a few buck per month, but its worth it. The only downside is that with no multitasking, you can't monitor emails while using it, but calls still work.
[Windows Phone 7 General] cgibsong002:
How much data per hour or so does that pull in?
[Windows Phone 7 General] vangrieg:
If your operator doesn't provide a navigation solution, basically your only option is to find Navigon and sideload it on your phone - search xda for hints on how to do it.

Rumor is that Navigon has an exclusive deal with T-Mobile Germany until summer, so it won't be available on Marketplace until then.

On xda, there are device-specific forums with "Accessories" sections, check out the forum for your device.
[Windows Phone 7 General] thealanshow:
I think every WP7 user should get A to Z. It's in the marketplace and its free. It's amazing, but I'm not sure if it only works in the states... It has turn by turn directions!!!
[Windows Phone 7 General] lekki:
It's actually called A to B but yes, it is pretty sweet.
[Windows Phone 7 General] deeken:
I'm with the OP on this. I need a map based turn by turn GPS software such as Garmin, Tomtom, iGO or Navigon. Using bing or A to B doesn't cut it. The last thing I want is to be lost in a dead zone. For me this is a deal breaker and one of the many reasons why I am still with WinMo.
[Windows Phone 7 General] emigrating:
1. Since you're from Germany, your best bet if you need navigation now is to simply get a T-Mobile device as they come pre-loaded with Navigon.

2. Depends on the device you get. We have Omnia7's and purchased the active Brodit holder for it, great holder. Only downside is that it doesn't play nice with the phones once you put gelaskins on them.
[Windows Phone 7 General] N8ter:
AT&T Navigator costs $10 a month. That is NOT cheap...

10% (maybe more) of your phone bill per month, or $240 over a 2 year contract. You're better off buying a $100 GPS system with offline navigation with updatable maps...

Those GPS services preloaded on these phones are a joke. That's why Google Voice Navigation (and later Bing Voice Navigation) was such a big deal...
[Windows Phone 7 General] cgibsong002:
I'm with you guys here. I'm only on a 200mb plan. Why would I pay $10 per month for Navigator when it'll probably end up going over my limit and overcharge an extra $15 for data? I would have no problem paying a good price for an offline map based GPS.
[Windows Phone 7 General] derausgewanderte:
totally agree, "a few bucks" is maybe 2-3, but 10 is dead-end. same with their family tracker. I use my Garmin and a few times sideloaded Navigon.
[Windows Phone 7 General] RoboDad:
You are, of course, entitled to your opinion, but from my experience (I use Navigator, and I've owned two different dedicated GPS units) you are dead wrong. $10/month for Navigator is quite reasonable compared to what I would have to spend to get a GPS unit with comparable features and quarterly map updates.
[Windows Phone 7 General] cgibsong002:
I got my GPS for 120 and it was a good quality Garmin. A year in and you're already paying that for Navigator with less features... and that's if you're already paying for unlimited data.
[Windows Phone 7 General] SuperSport:
Now that WP7 has FREE tracking built in, there is absolutely no need for the ATT Family Tracking. iPhone and Android Both offer Free Tracking also. I hate to admit it, but iPhone does the best tracking. It pinpoints down to within 20 feet.

I feel both ways on the GPS functions. Personally, I prefer a good GPS unit over GPS on my phone. But, it is nice to get the extra features found on the connected GPS devices. ATT Navigation is actually quite a nice program to use. I used the free trial and was quite impressed, even though I've been a LONG time user of TomTom and Navigon. ATT held it's own, but as others have mentioned, being left without connection, thus no Navigation is just not acceptable for me either.

TomTom, with map updates does end up costing just about the same as ATT Navigator, with the exception of the Data. If you don't use much data, it's probably a wash, but if you go over your data plan, I'm sure ATT will end up being much more expensive. Being able to search for ANY Point of Interest is a big plus on the Connected Navigation. TomTom and Navigon occasionally don't have all the POI's needed.

The newer TomTom's now have the best of all worlds. Free Lifetime Map Updates, Offline Navigation, Online Search, etc... Problem is, they cost around $300-400 for all that.

I'm holding my breath that TomTom will support WP7, especially now that Microsoft has opened up the Dev a bit for them. TomTom on iPhone is really nice to use, so it should be that much better here.
[Windows Phone 7 General] N8ter:
Integrating WP7 with Windows Live Family Safety and introducing Bing Maps Navigation and a service similar to Latitude would work, and you wouldn't have to pay AT&T for it.

And for the poster above talking about Navigator: Who cares. Navigator subscriptions are a scam and the only carrier that has a good deal is Sprint because they give it for free with their $69 (not 79) plan. I'm just aghast that people pay these prices for a Navigation app with no offline capabilities on a subscription when GPS hardware is so cheap and actually quite attractive these days (not to mention lots of new cars are coming with them built-in).

You can spin it any way you want, but they make no monetary sense to consumers when you can either get a phone that has it for free, or get a GPS unit that costs half as much as Navigation costs over the course of a your cell phone contract.

One of the reasons Android took off so well is cause of the free Navigation, and even WP7 has this. Microsoft just needs to get off their asses and bring Voice-Guided Navigation to WP7.

I wish I could just buy Ovi Maps for a flat fee or something, for WP7. But in the meantime, I just carry my Vibrant everywhere and use it for that purpose instead.

Hell, even MapQuest has a Voice Guided Nav app for Android now: https://market.android.com/details?id=com.mapquest.android.ace&feature=search_result

Microsoft either needs to work with some company like MapQuest, another third party (TomTom, etc.), or get Bing Navigation up to par.
[Windows Phone 7 General] truffle1234:
A to B do not work here, i am using dedicated GPS nav device fast and cheap... SGD300/-
[Windows Phone 7 General] RoboDad:
It's disingenuous to try to lump your data plan into the "cost" of GPS navigation, unless that is the only reason you have the data plan. Since almost no one falls into that category, the cost is obviously amortized (I use my data connection for email, YouTube, weather updates, downloading apps, and about 20 other purposes).

As for your experience with your $120 Garmin, we'll just have to agree to disagree. My experience has been very different.
[Windows Phone 7 General] N8ter:
No it's not. It can change your data requirements. If you use the GPS apps a lot on your phone, a 200MB data plan may not be enough. With a dedicated GPS system, you may be able to just use a 200MB data plan. Some people are like that.

So in the end you end up paying a ridiculous amount of money for the GPS services and the data plan to facilitate it, than just getting a dedicated GPS device.
[Windows Phone 7 General] N8ter:
Agree.

1. It doesn't work (as in, I've never gotten it to work).

2. It has that banner on the screen at all times, which is a waste of useful screen real estate in this type of application.
[Windows Phone 7 General] macjr82:

Alright guys so today is the first time I've had this problem. I'm running warm z twopointtwo 4/7 nightly with chads 12/23. For some odd reason today my phone has been overheating. Now I wasn't able to get an exact temperature read but my guess is somewhere around "way too effing hot" degrees Fahrenheit. I say this because my phone actually got so warm today I almost couldn't touch the screen. I was seriously expecting thermonuclear meltdown! I pulled my battery and let it cool off and all was fine but still it worries me. I wasn't even doing any intense processing. I was only using the xda app and reading some threads. Throughout the day it hasn't got quite that hot but its been running noticeably warmer than usual. My battery also seems to be dieing slightly faster than usual. Now my phone is a certified refurbished less than a month old so I can't imagine this being a matter of my battery starting to die.....so anyone have any input on what could be causing this? Could it be Rom if kernel related?
[Droid Incredible Q&A, Help & Troubleshooting] k_nivesout:
I've tried that rom/kernel combo and it worked for me. Are you using a non OEM battery?
[Droid Incredible Q&A, Help & Troubleshooting] elixir911911:
Nope I have the original battery still in it and everything....I mean it works beautifully outside of a few occasional hiccups here and there but nothing that isn't to be expected.....but the heat problem never happened to me before.....I mean trust me I used to have a crazy overclocked Eris that loved to get hot but never this hot. And I haven't even overclocked my dinc yet....its just kinda odd it was a one time thing but it was almost too hot to touch. It spooked me I legitimately feel like I was very close to processor meltdown.....
[Droid Incredible Q&A, Help & Troubleshooting] elixir911911:
Any one else with suggestions?
