Anybody knows if LEO's hardware is capable of capturing HD video ?
The hardware (read speed) of LEO should be more than enough for HD I belive
Is WM 6.5 the limit or is it other things ?
That is an interesting question.
It should be capable. As HTC Bravo which will be released next year, also uses Snapdragon 1GHz, supports 720p video recording.
Given that the Leo isn't even capable of playing 720p video, I find it very hard to believe that it is capable of encoding 720p video in real time - encoding video is far more computationally intensive than decoding it.
WideVGA / WideNTSC
Well, 720p is maybe too much, but it definitely should record wide 800x480 videos (as Samsung Omnia) !

A bit inaccurate.
It is not capable of playing 720p video without hardware acceleration.
Actually, the hardware is capable of playing AND recording 720p video. We just can't use it because we don't have the software.

o really? How do we know that the Bravo perhaps doesn't have a specific hardware chip for 720p videos? Does the HD2 have such a chip or is snapdragon just capable?
Seeing the crap quality that we have in 640x480 with 20fps, I dout it that we will get 720 or 480P ever.

It's Snapdragon, which is not only the 1Ghz processor, but a platform that is capable of playing/recording 720p video.
If you convert a video to the right format, so that it uses the hardware acceleration, you can already play 720p right now.
This is the same with any phone and the reason why lots of phones only allow a specific file format (e.g. you have to convert anything you put on an iPhone with iTunes first).

Can you cite any examples of an HD2 playing back 720p video at an acceptable frame-rate even with hardware acceleration?
What's with the Helicopter demo from the Omnia? Should work, afas I read.
EDIT: OK, I searched for it again, seems like it's not 720p but 480p. Seems like nobody has yet tried 720p with hardware acceleration?

It means you don't have to faff about with video conversion - you can download just one version of the file for use either on a desktop PC or a phone.
However, the importance in the context of this thread (as you would know if you'd actually read it before posting in it ) is that if the HD2 cannot even decode 720p at a satisfactory rate, how could it possibly encode 720p video in real time, given that encoding is far more computationally intensive?

I did read the thread. I was actually asking that poster a particular question that had nothing to do with the capabilities of the phone. Simple matter - an 800x480 screen will only play a video (in landscape) at a 480p maximum. Running 720p video will not look any better.
It was just a question. No need to ave a go.
Incidentally, I've got 720p videos converted from MKV to MPEG using the wonderful mkv2vob, and they play a treat.
this maybe possible I've came across ways to increase the bitrate at which the camera records at and also fps.
in a few days I may have another camera tweak but for video quality I'm just lookin for a exported red file viewer for ppc

What are you saying ?? That you actually converted a 720p video (which is basically around 1280x720) to an Mpeg using MKV2VOB (which doesnt change the resolution, so its still around 1280x720) and you have manage to play it on HD2 ???

CorePlayer (v1.3.6)
Coreplayer cannot play video greater than 1008x1008... So either you're lying or you're confused. But either way you're not playing 720p with Coreplayer.
Hi folks,
Is there any posibility of a lagfree playing of those videos ?
It sucks watching Videos with less than 20fps...
3.1 is supposed to improve playback... just no idea if it will improve 720/1080p playback

That Google site is mine.
Converts all my 720p.mkv files perfectly, the only issue is the files are big, 2-4 GB, but the quality is outstanding. They even play on 'Movies' which darkens the navigation bar.
i was looking for something like this so many times before, but I never found a stable movie app. On my Samsung Galaxy S II however, it's no problem at all. And that's a freaking phone man! But it's no wonder the hole system is so fast. It makes my newly aquired Iconia looking really sluggish and outdated :-( I don't know if I gonna keep this tablet or gonna look my movies on a 4.3" screen...
I asked Acer customer support whether they're ever going to support additional formats and they replied that they won't ever add support for MKV and can't comment on the rest. So official support for MKV is out the window.
Mkv isn't a video format, it's a container. It's just that most mkv's don't contain only baseline h.264, which is the only supported video format currently. The most benefit would come from adding support for main or high profile h.264

I know, it still doesn't help at all if the video player application or framework don't support the container format. I personally love MKV, it's handy to slap in two different audio tracks and subtitles in English, Finnish and the hearing-impaired version, plus any metadata about the movie itself. No need to hassle with several files then.

Indeed. I tried transcoding a 1080p movie to 720p in constant quality mode, both in baseline and high profile modes, and while the quality was the same the high profile one used a lot less storage space. With storage space being rather scarse on mobile devices....
Well, we can only hope. But I don't know if the DSP is beefy enough to decode high profile or if it can be re-programmed to support it. Some DSPs are hardcoded and can't be used for anything other than what they already do when shipped. I don't know anything about Tegra 2 internals so I don't know what to expect.

The nVIDIA Tegra 2 250 is fully able to hardware decode:

And this is for 1080p both enc/dec
Why ACER can't (won't) support them is beyond me! Even my Single Core 7" Samsung Galaxy TAB can play all 1080p videos I have thrown at it!
And here is the full spec of the Tegra 2 250 Link!
Is it maybe because of that, that I play these videos from my USB-HDD?

You can always copy one of them to the TAB and see if there is any change ( I doubt it)
Using a OLD 60gb usb hdd (literally 8 years old)
And it does not seem to matter - even with the low speed of an old external drive I have no issues playing video from it.
.Mkv -- Regardless of where it is stored is not going to work on the Iconia right now - i don't think there is anything anyone can do or change to fix that right now - the system will not?/can not? use the hardware decoder on mkv files - and software decoding, even for a low bit rate video file is always going to suck.
Hopefully 3.1 will improve our video performance - but I find it a very simple matter to just transcode a video file if the only source I have handy is mkv. Plenty of great and free tools that make the process pretty darn easy. I watch a lot of movies/TV on my a500 - and get a great experience as long as I don't throw .mkv files at it.

My understanding is tegra2 will support h.264 high profile up to 720p @ 20mbps, but only baseline profile for 1080p.
With regard to the container format vs video format thing, I'm under the impression that container format support can be added by an app - so even if Acer never support mkv in the default player, if they do add hardware high profile h.264, then other apps should be able to play an mkv that contains high profile h.264 with hardware acceleration.

From playing around with PRIMEE, mkv containers are split appropriately and if the video format is supported hardware decoding works. The problem is that there is no support for AC3 therefore majority of compatible MKVs will play very well but have no sound.
Unfortunately once software encoding is enabled we are back to the same stuttery playback issues.
I personally don't believe it's Acers' job to add playback compatibility, I personally believe it should be built into Honeycomb as a baseline. Honeycomb is a tablet OS and as such should be expected to play popular video and audio. codecs. Saying that, if manufacturers did add additional codec support it would be a solid competitive edge.
Use mobo player.

Ah, that's good to know, so with a baseline h.264 payload an MKV will play fine on stock?
I think it probably IS Acer's job to add codec support, frankly. At the end of the day we're talking about hardware acceleration, and Android provides the software framework for that to work, and it's up to the hardware vendor to make it work with their specific hardware.
Frankly I think Nvidia should be doing it though - it'd do wonders for Tegra 2 sales if they offered up code to support hardware acceleration for their platform on Android.
I guess you didn't really do your research on video playback on Honeycomb tablets, did you?
You can not blame Acer for poor HD playback when, frankly, this is a Google/nVidia issue. Currently no 10" Honeycomb tablet can playback high profile encoded HD vides--smoothly, if at all--without reconverting said movies.
There may or may not be a *real* fix in the future (quad core Tegras are right around the corner, so...), only time will tell.

I bought an ACER device so I'll blame them! Problem here is that the Tegra 2 chip is capable to decode and encode the formats at 1080p without problems! The fact that Google still hasn't taken advantage of this feature doesn't mean that ACER couldn't!! To back my words here is an example:
Samsung! The Galaxy S and Galaxy TAB (7") they have much superior video codec support! I'm playing 1080p movies just perfectly on the Galaxy TAB. Samsung have invested in codec support and optimized it for the platform (both Hardware and Software) The Hummingbird CPU is Single Core! So why can't ACER do it? Maybe because they never did something like this before? Maybe because the have done only the hardware till now and they don't have the programmers that can pull this of? Ones the managers at ACER understand that selling thees devices without enhancing the base that Google provides won't cut it, I think we will have a very good device (not that it isn't good now but...)

does the sound and the screen match?
Why would you do that?
The screen resolution is not even 1080 pixel height.
Don't you know that?

Let me know what your research shows. I've been converting blu ray and mkv into 720p mp4 using DVD catalyst 4, real simple setup. From what I found out, mkv files do not work on any tablets because mkv is a container. If you convert it to mp4 then any tablet can handle it, including my phone galaxy s captivate . Takes me an average of 3-4 minutes per TV show and 10-20 on a movie. I stopped encoding at 1080p because there was not much difference other than size of file.

they work but not with high profile settings. you need to reduce them.
you can google what high profile for mkv is.
The answers you are looking for: http://forum.xda-developers.com/showthread.php?t=1060825
mkv is not a format, its a container for H.264 format.
You should be asking "is it possible to play 1080p H.264 in the galaxy tab 10.1?"
The answer is yes BUT (and a BIG BUT) you can only do so if the H.264 file is encoded in the old H.264 baseline profile which nobody uses anymore.
Tegra 2s video accelerator is way to slow to play H.264 videos that are encoded in the popular Main/High profiles which everyone uses today. Yes its unfortunate but you have to recode all your videos to baseline profile if you want to watch on ANY tegra 2 based units.

The tab, along with every other Honeycomb 3.1, tegra 2 device plays H.264 high profile 720p and main profile 1080p video just fine.
Although given the screen resolution, playing back 1080p video of any profile is pointless.

Correct it CAN play them back but at only very low bitrate and 1080p is not pointless since you can hookup to TV or monitor via HDMI
I did some testing on bitrates for the Teg2 at 720p HP here,
http://forum.xda-developers.com/showpost.php?p=15054949&postcount=250
it does OK at 6Mb/s, and chugs when bits hit 10Mb/s. 6Mb/s avg is about the ceiling for most 720p videos, so one can generalize that the Teg2, at HC3.1, will play a fair number of 720 H264 HP videos (in MP4 format). Ruminations are that HC3.2 will speed things up a bit further.
The clip, along with others, are here if anyone wants to try them:

I've played with h.264 video on the Gtab, Use Baseline profile for best results. I've done some encoding in High Profile, and baseline, and compared screen captures, and you can't tell the difference, it has mostly to do with Compression, the higher your Profile (Ref Frames, B Frames, CABAC) the smaller your video file will be without suffering Quality lose. Just that higher profile requires more horsepower to decode, which Tegra 2 does not have.

Which explains why I am playing 720p24 high profile h.264 with no problems. Oh. Wait. No it doesn't.
Tegra 2 can handle high profile fine at 720p as long as you avoid wighted p frames. However the stock player does not. Enter diceplayer, built on the NDK and supporting all T2 decode capabilities. The stock player is totally borked.
1080p however is another problem. But you'll probably hit the fat32 4GB file size limit with those anyway before you encounter issues with high profile content. None of my 1080p MKVs will fit on the device anyway due to the fat32 limitation, so transcoding it pretty much a given. So I tend to go to 540p or even 480p just to save space. The screen is small, and while I can tell the diffeence between a clean 720p encode and 480p it doesn't bother me in this scenario. And if you drop down to 480p weighted p frames work again.
So, essentially Mr. Element, you don't what the hell you're talking about.

not sure about 1080p that's going to be hit and miss especially if you have big file sizes.
I'm using revolver 3.2 at 1.3 and can confirm 720p playback with file sizes of 3 gig or so play perfectly with dice player.
This can play back 1080P files just fine....DEPENDING on the bitrate. It's a limitation of Tegra 2. If the bitrate is high, it will have problems. Just like 720P files with really high bitrates have the same limitations.
Honestly, why does it matter? If you're outputting through HDMI to watch things, then I can kinda understand, but the screen itself only supports 720P. Why bother with 1080P?
Just out of curiosity, does overclocking improve video playback?

This can play back 1080P files just fine....DEPENDING on the bitrate. It's a limitation of Tegra 2. If the bitrate is high, it will have problems. Just like 720P files with really high bitrates have the same limitations.
Honestly, why does it matter? If you're outputting through HDMI to watch things, then I can kinda understand, but the screen itself only supports 720P. Why bother with 1080P?

Bitrate, uh?
How much is "really high"? 10mbps? 16mbps? and why the lower the resolution the higher the bitrate it can handle, if I got your post right?
Nah. I have a 1080p file, 16mbps. Plays well without overclock. I have another 1080p file, 10mbps, dosen't play well even at 1.6ghz. 720p file, still 10mbps, needs overclock (even 1.2ghz is enough). The difference between them? the kind of encoding. All this with Diceplayer, not the horrid Rockplayer, mind you.
Diceplayer works on most of my DSLR footage 1080 with 40-60datarate

I'm struggling with 720p encoded @L4. 1.. Mostly all L3. 1 plays nice in diceplayer.

If I remember correctly, movies encoded in High Profile will not play back well. Main Profile is the best this machine can handle. I believe it's a Tegra 2 limitation in general.

not sure about 1080p that's going to be hit and miss especially if you have big file sizes.
I'm using revolver 3.2 at 1.3 and can confirm 720p playback with file sizes of 3 gig or so play perfectly with dice player.

Let me comment on that:
LOL
Without OC, DICE player (and transformer itself) can only play Level3.1 content and it will slideshow on 99% of internet standard (scene) releases. If you think 'plays perfectly', then you're brain and eyesight damaged.
With OC, you can play play simple 720p content (think WebDL releases) with decent quality (though they will still drop frames in more complex scenes), but more complex releases (think blueray rips) will drop frames on most scenes and slideshow totally on more complex ones.
You would have to be really lucky to find a 1080p movie that will play. Many won't open at all, rest will be dropping frames constantly. When ASUS said that 3.1 update make 1080p playback possible, by playback they meant rendering first frame of the movie.
Dice player is the best
go for it
As mentioned on the other posts about HD playback, the hardware decode of 720p or 1080p H264 with AAC is currently broken in 3.2. Worked fine in 3.1, then got broke. Asus are aware of it and have promised a fix.
If you have such files (e.g. BBC iPlayer HD content) then no player will be able to play them back smoothly as software decode simply can't handle them. Only option is to either transcode or downgrade to HC3.1 to get hardware decode back.
Let's hope the fix is not far off now.
bro just play 720p. trust me you THINK you can tell the difference between 720 and 1080 on a 10' screen but you cant......unless your not human

Well, there cannot possibly exist a difference between displaying 720p and 1080p on a 1280x800 screen, since all 1080p content would be scaled down to 720p. Where 1080p would actually matter is if you often connect to a big monitor or HDTV that is capable of 1080p, such as I do on a regular basis for when I want to watch movies without having to boot up my desktop computer. There is definitely a noticeable difference between 720p videos I've converted with Handbrake and the actual 1080p Blu ray movies, but it's not really a big deal for me.
My suggestion for those truly concerned about high quality 1080p playback would be to buy a netbook equipped with a Nvidia ION or comparable video chipset, as I have had no issues playing Blu ray from my own ION-equipped nettop.
yeah my MX player would lag like crazy. Dice is the way to go!

ah i see. then YES. there would definitely be a difference. I just assumed you were watching directly on the TF. my mistake
the Iconia tablet (stock rom 3.2) has a most troubling issue: no (or no smooth) video playback of HD video files, mostly H.264 encoded mkv and mp4 files. Acer and Nvidia claim the device can run 720p and even 1080p in h264 base profile but the bitter reality is that even 90% of 720p video files don't play smoothy due to lack of proper hardware acceleration. this is really a huge disappointment as even most of today's discount phones can play 720p video and i got me a dual core device with a HD screen and a GPU from a dedicated graphics expert company but have to stick to SD video.
i found a statement in the Nvidia developer forum saying that Nvidia is working on this problem with some software partners which indicates that there might be a software solution to this sometime soon:
http://forums.developer.nvidia.com/...6/is-tegra-2-support-neon-intsruction-set-/p1
my question: is a software solution realistic or maybe just a waste of time? personally i doubt it, especially since the successor, Tegra 3, again includes NEON.
but maybe a custom rom like Thor could add enough horsepower to the device to enable at least smooth software decoding? anyone using this rom already noticed a performance gain?
i am looking forward to your comments.
Just install MX Video Player. Plays everything, perfectly smoothly.

you think i would investigate in hardware related stuff and post here if there was a player that could handle all HD video? MX player clearly does not, nor does any other player (dice, mobo, rock, just to name a few of the better ones) handle high profile H.264 video on Tegra 2 devices. so 90% of the stuff available online is not working, means they wont play at all or have massive framerate and sound issues. go and check out the latest movie trailers available in 1080p mp4 or download an x.264 encoded mkv file of your favourite tv show and you can see for yourself.
if you insist on your statement, then please put up a video source so i can verify. i would really love to learn that you are right and i have just a broken device ;-)

Well if you're trying to play 1080p video on a device that only has a native resolution of 1280 x 800 as this statement indicates, then the joke is on you sir.

it's Acer and Nvidea who claim that Tegra 2 can play and output 1080p video (base profile h264) through HDMI, not me. i've just fallen for their marketing, trying to play some of my favourite 720p tv shows on my so called "HD device"...
also, i don't get your point about the resolution. are you trying to say that a full HD display is mandatory in order to enjoy a 1080p video? or that its content will look better if video resolution would match the Iconia display resolution? sorry sir, i really think you are the funny guy here.

i did not say i wanted to play 1080p on my device - you are clearly not able to read and most probably just a fanboy.
besides, i still don't get your point. i would chose 1080p over 720p if i had the choice. and you would stick to 720p or SD because you think there is no "benefit" in playing higher resolution content on smaller display? well, quantified the benefit would be at least 80 lines more content, don't you think?
there might be cases where a hard- or software scaler messes up while downscaling a video and picture quality degrades, but generally the higher the resolution the better the picture quality, regardless of display resolution.

Atleast I can play baseline and normal profile H.264 content at 1080p just fine. It's only high-profile that reverts to software and doesn't play well.

The display itself is 720p, so trying to play 1080p content on a 720p display is kind of pointless. You won't see the extra resolution anyways. Though if you're playing through HDMI to a 1080p display then it makes sense.

Not entirely correct. Higher resolution doesn't equal better compression quality, so you can easily have 1080p video that looks like ass crap, and you can have SD video that looks better.
That said there are lots of reasons to choose 720p over 1080p on A500: 720p high-profile video generally looks much better than 1080p baseline-profile, high-profile fares a lot better in high-motion scenes, and high-profile takes less storage space than baseline-profile. And well, since you can't see the extra resolution anyways you're just wasting extra storage space on stuff you can't even see.

A software solution will only boost applications that are specifically designed to utilize it, and the hardware simply isn't fast enough to decode 1080p high-profile in software at full speed, so no, no matter what NVIDIA is claiming they cannot do magic tricks here.

Thor or some other custom ROM can only increase clock speed, there is nothing else to be done about it. And you can increase clock speed even on the stock ROM anyways.
But as I mentioned I have absolutely no problem running 1080p baseline- or normal-profile content, or 720p content, because I am not using the stock player. Use one of the players from Android Market, they're a lot faster and smarter than the stock player.
Also an important note to you: the stock player reverts to SOFTWARE if audio is AC3 encoded. That is probably the issue you're seeing. The players from Android Market do AC3 in software, but send the video to the hardware, so that's why they don't lag with AC3 audio.

I was on topic, if you can't understand that attempting to play 1080p Res videos on a 1280x800 display has no benefits whatsoever, then maybe you need one of These.
I honestly don't understand what is so friggin' tough about understanding the concept, and you clearly stated 1080p in your first post.
He's trying to playback through the HDMI port, muppet.
Here ya go, educate yourself.
" If the incoming source has more pixels than the display's native resolution, you will lose some visible detail and sharpness, though often what you're left with still looks great. If the incoming source has fewer pixels than the native resolution, you're not getting any extra sharpness from the television's pixels."
http://reviews.cnet.com/hdtv-resolution/
guys, and ladies, please, this thread is not about pro and contra of full hd content on smaller displays.
the question is:
is it likely that (at some point soon) there will be a workaround to overcome the issue of the missing NEON video instruction set on Tegra 2?
again, my goal is not to play 1080p content on my Iconia, just some 720p stuff, mostly TV shows encoded in H264 high profile mkv files. and no, they wont run using MX player or any other player currently available. and i guess that's also due to the missing NEON. please see the link provided in my first post.

thanks. well, in respect to 1080p content i don't have much hope either. but, and again, 720p content encoded in h264 high profile does NOT work for me. i have massive framerate issues and sound also drops off completely after a few seconds. i tested with google, rockplayer and mx player (all of the latest builds).

You sir are an ignorant boor who is incapable of reading. You couldn't read the posts properly and you can't even read your quote properly.
A 1080p file has more visual information. For example, it's possible to see a small mole on somebodies face in 1080p that in 720p or lower has been smoothed out and is now invisible. Playing that 1080p file on a lower resolution device gives the possibility that the mole will be visible depending on how the hardware scaling is done and since most hardware scaling isn't going for compressed file size and won't be applying gaussian blurs etc... you WILL see that mole.
The new Nook Tablet and Kindle Fire have the same screen resolution, one streams videos at SD and the other at HD. Now even though the tablet isn't capable of HD the one that streams HD is noticably sharper and has more detail. Go look up the pictures if you want. Take your own advice and educate yourself before you berate people for their ignorance when it is you who are ignorant with poor reading comprehension.

Mate, it doesn't work like that. It doesn't matter if the picture is scaled down before compression or after decompression, it's still scaled down. And no sane compression technology uses gaussian blur.

The difference is due to the fact that the HD video is compressed with better quality settings than the SD video. Besides, Kindle Fire IS 1024x600 pixels in size which means it is indeed almost 720p HD resolution meaning that HD content only needs to be scaled down by 120 lines whereas SD content has to be scaled UP instead: well, OF COURSE it will look like crap.
In other words you're comparing apples and oranges and you don't know what you're talking about either.

I just tried that file with Dice Player. It stutters for about 5 seconds, then settles down and works like a dream. In other words, working just fine on my tablet.
I had problems playing 720p mkv files as well, no matter which player I used. The stock 3.2 rom appears to be missing the framework for hardware decoding of these files. No such problems since installing various Thor roms though. They all play fine now. 1080p is probably too much though. I use mx player by the way.
