720P Playback horrible?

Hey guys,
So they boast about the 1080p playback on the Samsung Galaxy Tab 10.1, however I haven't had much luck with this. I tried putting on two different 720p video files on and both of them have sub-par playback.
One of them is an MP4 with h.264 and it plays okay on the default video (gallery) player but theres a bit of a stutter and doesn't play extremely well.
The other is an h.264 MKV and that doesn't even play audio in certain cases and the video doesn't play well at all under the default gallery application.
I tried three other media players - rock media player, Vplayer, and doubletwist and none of them play it any better. I find it sort of strange that it's having trouble handling these sorts of files. I can maybe understand the MKV file but the standard MP4 file is a little concerning

I find Vital Player performs better than the ones you have already mentioned. QQplayer is ok sometimes too and I've heard people talking about drobo player but I have not tried yet.

VitalPlayer played my mp4 a little better almost perfect with hardware decoding, however the mkv was still problematic :-/

Try:
MoboPlayer
and
MoboPlayer Codec for ARMV7VFP3
It bring in Tegra 2 Support not yet optimized but still pretty good.
Also if you have rooted your tab take your CPU off interactive (Default and horrible) and put it on Performance or OnDemand.

It's not a software flaw , it'tegra limitation to playback high profiles encoded files. Tegra allow hardware decoding of main profile Encode file only.

Interesting, I haven't tried MoboPlayer yet but I will give it a go tonight. In regards to the cpu being on interactive. What?! Really? I was trying to find a reason to root and that might be one is to put it on OnDemand.

I think he's saying that altering your CPU probably wont make much of a difference since it's the lack of GPU hardware decoding for high profile encoded videos that's likely causing any kind of stuttering. In short, it's not your CPU's fault or Honeycomb's fault, it's your GPU's fault.

Interesting, I find it odd though that when selecting hardware in certain players it does play better. But when selecting software in some players it plays better than other players hardware. It just seems like some sort of issue that isn't really making much sense.

Yeah, moboplayer wasn't any better either :-/

It is Tegra limitation and it is a problem for ALL Tegra 2 based tablets.
Go to any forum Xoom, Transformer, Adam Ink... i is general issue.
If one wants to play movies (and do other "super advanced stuff") one should have buy a previus generation tablet like Galaxy Tab 7" or Archos, etc.
Some of us still hope that retail GT 10.1 will come in with Exynos CPU instead of Tegra. If not it, than quite a lot of phones will be more powerfull than Tegra 2 tablet computers.
+ none of new tabs is divix certified like some of the old ones were :-(
I wonder how will TouchPad perform in that matter?
If GT 10.1 is indeed Tegra 2 based I am in trouble.
Watching movies (in bed) is quite important to me.
I will either wait for 10" HTC or Amazon tablet (gossip goes it will have Kal-El inside) or I'll just get iPad 2 (seems to be more capable in that regard than new Android tablets).

Is the ipad2 better at video playback?

If jailbroken - YES.
Its CPU (by Samsung) is more capable than Tegra 2 .

I have the iPad2 and Asus Transformer which uses the Tegra 2. My iPad 2 is not jailbroken and it surpasses the Asus Transformer for video playback. My iPad2 plays High Profile 720p MP4 with the stock player, and with AVPlayerHD from the App Store, I can play High Profile 720p MKV and it will support embedded subtitles along with xvid/divx avi formats.
The Transformer chokes on anything High Profile. Sure you can use Moboplayer or Vital Player as they support subtitles, but they only support external subtitles and they still can't play High Profile.
Don't get me wrong here; I'm not an Apple fanboy at all. Just clearing up that iPad2 is the better video player period and does not need to be jailbroken to do so.

How is the Ipad with youtube playback? It really bothers me that the tegra 2 tablets can't play videos in "hq" mode without horrible stuttering. I'm hoping 3.1 fixes this.

Ah, YouTube is a different story. The YouTube videos that the iPad can play are excellent... if they aren't Flash! However, there are browsers like Skyfire in the app market that plays flash but I haven't tried it yet. From reading reviews, 3.1 does seem to address those issues. All in all for YouTube, the Asus has the upperhand especially if you watch YouTube on the stock browser.

I tried watching youtube videos on the transformer with the youtube application and it was pretty bad. That was a while ago, is it better now?
Sorry for the derail.

I'm having no problems with the couple videos I'm watching now through the YouTube app. The only problem I get with YouTube is, of course, the HD playback in the browser but again I believe the Xoom owners have reported 3.1 fixes that.

Video playback capabilities of these Tegra Honeycomb tablets is a bit frustrating! My SGSII plays video and handles in-browser flash better (as in much better). I guess I will be connecting my phone to my television when I want to watch 1080p video, rather than my tablet...

True... but in that case... why would I get a tablet?
Or (that will be the case for a lot of ppl.) if you can only afford one of those?
New (fully capable) smartphone or tablet (that can only do some of the thing phone can but has bigger screen). Which one?
Not, to mention... what is the point in creating device, a tablet COMPUTER that is beaten in functionality and performance by phone.
HEY!! Samsung, instead crappy 10.1v (or 10.1 if it is with Tegra) make Samsung Galaxy S II in XL size - that is all most of us needs right now (+ Honeycomb) - and we're sorted .

Agreed, but to be honest with all these reviews of the I/O versions and those boasting Tegra2, it seems the new official 10.1 will have it. I'm really back and forth about returning my Transformer to try a new 10.1 out. I mean I only plan to keep either one until the Tegra3 Kal-el tablets start rolling in (Asus and Amazon rumored to roll some out this year). Financially it'd be smarter to just stick with my Transformer, but I've always been about design and build and the Samsung sure looks like it has the Transformer beat. Trade off for build and form factor are the loss of the microSD expansion though, which means (according to the J&R pre-order pricing) I'd have to spend $599 for a 32GB Sammy vs. the $399 16GB Transformer+$35 16GB class 10 microSD card.

So you recorded 1080p video on your SGS2, and it won't play properly on your PC?
Sounds like your PC is too slow, or it's not hardware decoding. Try Media Player Classic or KMPlayer if you're on Windows.

Ok ill try that.thx

LOL, yeah, this should go in the PC section, not SGSII section.
To OP: Try updating your codecs too, other than that... get a new computer!

I had the same problem with my sony vaio FW31J. Should be good enough to play it, but it was jerky and images stopped sometime.
I have no idea why but it would only do this when my laptop wasn't plugged in.
When I was on battery it had the problem. And no I did not have any energysaving module on.

installed these codecs:
http://www.cccp-project.net/
the right click on file and choose open with, choose media player classic, if this isnt very smooth then get back to us.
What generation of gfx card do you have, gerforce, ati, 5,6,7, 280,460 etc

Google CCCP to get Media player classic (for your PC) and make sure you get DXVA enabled. Every Windows versions has a slightly different setup, and only about 2 year and younger video cards (AMD/Nvidia)can take advantage of DXVA. Can someone say if any integrated Intel video chipsets can do DXVA?

LOL at mobile phone being faster than computer

Lol i actually have an m15x.the computer im using is an old athlon.ill try on my own i think.

As much as people think it might be a pc issue I experience the same thing on my i5 750 @3.9GHz. Op I think it is due to 1080p video recording not being as many fps and smooth as 720p. I've watched other peoples recorded 1080p as well and it's the sam whn the phone camera is panning. Some people may not notice it as much or choose to ignore it but I just use 720p for now. Maybe with some overclocking it can push out a steady 30 fps 1080p.

What are the specs of your computer? I've played plenty of 1080p videos from my phone on my comp without issue.

Like mark 2222 says plenty of power its actualy a p4 2.9, with 2gig ram.old but should suffice.720 plays back smooth

P4 2.9GHz is obviously not enough if you can't play it back. I've tried dual Xenon 2.4GHz (about 8 years old) and it had problem playing back 720p content so don't expect your 2.9GHz to play back 1080p. Buy a new graphics card, or a new computer, or don't try to play 1080p content.

It's often not the processor that's the issue. We can see that the SGS2's and Tegra 2 processors are fine, but much slower than an i5.
The problem is often the graphics card. Don't blame the processor or the phone until you're sure you're using your graphics card to render the videos, not the processor! That's what they're for! It also needs to be capable of hardware decoding 1080p.
1080x1920 = ~2 million pixels
720x1280 = ~1 million pixels
1080p has more than double the number of pixels as 720p. It's a big step up!

lets just be clear here, this is NOT a pc spec issue, I can play hd movies on my 6 year old laptop which has a crappy celeron cpu onboard and an ati radeon 7000, this is a codec issue or something to do with the way the video is recorded. I will do some tests on my rig and report back.

Haha, no way. That is not powerful enough. I had a P4 3.2 and also a graphics card that had hardware acceleration of 1080p wmv files.
When playing back normal 1080p video files (xvid), the framerate was low at about 5 fps. When playing 1080p wmv files, the hardware acceleration from the GPU got it up to the 30 fps rate of the video file.
That's also the reason why the I9100 can play back 1080p with no issues. The Exynos chipset has hardware acceleration of the scaling of 1080p to the screen resolution. Tegra2 on the other hand does not have this, so it struggles with 1080p videos.

That's more than powerful enough. I played back 1080p AVC video perfectly on an old media box running a craptacular P4 @ 2.4GHz or somewhere there.
Your graphics card needs to be able to decode it, also try another decoder/codec pack meant for HD video. CCCP is ok, I swear by CoreAVC. It's not free, but you can find 'free' copies floating around google, try and buy. It's worth it if you're on a crappy computer and don't want to upgrade your hardware.
I've tried playback of 1080p video from the phone and it's fine. Buttery smooth. Most likely a problem with your computer then.

Is the file copied from the phone to the pc or are you trying to run it from the phone attached as mass storage? Could be the usb port being slow to transfer if this is the case. Maybe try downloading a test MP4 from the web and see if it is ok?

rubbish, a pc of that spec will tear it to bits with the correct codecs, my ageing P4 with onboard intel graphics runs it smooth at work, like i said this is not PC spec issue, I suspect we are not being given all the relevant info here from the OP, we are missing some vital information which will ultimately turn out to be the cause.

h.264 Encoder for Transformer/Tegra 2

I'm looking for an application which supports h.264 encoding on the Tegra 2. My desktop PC is just way too slow at re-encoding and the fans get too loud to leave it running over night.... so I thought I might do my re-encodes on the TF itself, but so far I haven't found an application which supports this. Does anyone know if there is one?

I haven't seen one but I have the feeling it would be horribily slow...

This is Obviously going to be slower than realtime, otherwise you'd play the movie smoothly without the need to reencode.

Not sure why you would think the TF with a 1Ghz mobile chip and 1G ram would be faster than a desktop, unless your desktop is very old.

unless your PC is more than 5 years old, there is a good chance it will still encode h264 faster than the TF...
what numbers in fps you are getting if you use handbrake to encode H264 720p in High Profile? I have a rather beefy desktop with i5 2600k and it encodes about 65-70 fps, and my old dell laptop with T7200 runs about just over 20fps

I have a 2.8GHz Pentium 4 with 1GB RAM. From what I've tried so far my encoding speed hovers between 1-5 fps. So yeah, encoding on the Transformer can't be that much worse, and I wouldn't have to deal with roaring fans.

Tegra2 probably supports hardware encoding of h264 (for the camera for example) but apps won't have access to that unfortunately.

Hi10P video - plays in hardware or software? Has enough power for 1080p Hi10P rips?

Has its GPU support for decoding of such videos? If not, are four A15 cores powerful enough?

No and no, at least on the Snapdragon version.
Tried a 1080p vid now and a couple of 720p ones of varying bitrates.
The stock player only decodes the audio.
In S/W+ decoder in MX Player with 4-core encoding and only 16-bit colour depth the 1080p video still stutters, although marginally improved Vs last years hardware. Of the 720p videos the lower bitrate video was fine, the slightly higher bitrate one was again slightly improved Vs last years hardware and watchable if not completely smooth (watchable for me that is, YMMV of course).

Thank you. Sad to know that 1080p Hi10P isn't yet playable.

but 1080p videos coded like the youtube videos and such, are 100% playable, right?

HEVC Encoding Support

Hi,
Is the Nexus 6P supports HEVC encoding? When I record a UHD video, it appears to encode using H264 and I don't see the encoder in android.media.MediaCodecList.
Seems unexpected since the Snapdragon 810 offers HEVC capabilities.
cheers

I feel as if it is. There's no reason why it doesnt use it. The phones fast enougj, the ram and internal storage are fast enough it just doesnt nake sense. Maybe it's the sensor? If the API doesnt have support for it through the driver then it won't happen anytime soon
