[Q] Why does 720p flash videos still stutter on my Xoom?

I just got the 3.1 upgrade on my wifi Xoom. I then downloaded the 10.3 flash player, but still when I play 720p Youtube videos, my Xoom will stutters so bad, that the videos are unwatchable. I thought these updates would have fixed the problems. Am I the only one like this or does everyone's xoom stutter on HD youtube videos? My Xoom is stock and unrooted.

Are you watching them in browser? Why? I haven't tried that, but i will try when i get home and let you know.
HD videos in Youtube app play just fine on my device.

I was just about to post something about my video play back. When I first got my xoom. I come watch Tekzilla and Hak 5 HD versions of the show. Now its like watching a scratch dvd but the audio is great. I'm stock as well but not updated to 3.1. I hope someone can help...

weird. Its super smooth for me.
Is your net connection stable?

Report your speed then if sufficient, troubleshooting can begin. If you're trying 720p on 1.5Mbps/384kbps dsl then you will get crappy performance.

I guess the videos that play aren't necessarily Youtube videos, but Flash videos.
For example...try playing this video on your xoom:
http://www.flashvideofactory.com/test/DEMO720_Heima_h264_500K.html
Mine stutters, the audio sounds ok.
It plays fine on my PC.
Speedtest on my Xoom is 12937 Down and 10935 Up...it definitely isn't a speed problem.

This stutters on my work desktop computer also, so i'm not expecting it to work on my Xoom, but i will try when i get home.
I admit, this computer is old: Win XP on AMD Athlon 2800+, 1GB RAM, ATI Radeon 9800 graphics.

I can't play that video on a dual core 2.66 ghz laptop, with 4gb RAM and a 50Mbps downstream connection.
I'm not going to hold out hope for my Xoom on that.

it stated that it isn't optimized for mobile viewing.

I tested http://www.flashvideofactory.com/tes...h264_500K.html video on my Xoom now and it doesn't play good. It plays about the same as my work computer did.
I also tested a random 720p Youtube video in full screen (on Facebook). It played just fine, without any problems.
FYI: WIFI only Xoom (US) Android 3.1 and Flash 10.3

Is this phone powerful enough to play Full HD videos? 1080p

Is this phone powerful enough to play Full HD videos? 1080p?
If it is, could you play smoothly YouTube 1080p rips? High bit rate .mkv files?
And what player you use for full HD playback?

dont think it will... altough i can play 720p mkv very smoothly with Diceplayer !! did test a couple 1080p which wasnt that smooth....altough i heard that converting into .mp4 results into much better playback because of native support

Of course it can play 1080p videos.
Using the standard Gallery, it can play the 1080p videos that the camcorder records, and it can (so far) play any 1080p MP4 video that I put on the SD-Card or stream from my media server.
There will be some file formats that it won't play, of course, but that's a problem with the format rather than the resolution.
It will also play 1080p MP4 videos through my Sony Bravia TV via DLNA.

abuserkadayf, sjgore, thank you.
sjgore, I see you got HTC Desire too. And it have trouble playing some 720p mkv, never been able to make it play any 1080p. MoboPlayer is the best all around player from point of format support, speed and UI. But there is like a dozen players that based on FFmpeg library around(VPlayer, QQplayer, VitalPlayer, RockPlayer etc...). Was wondering if new generation of hardware is able to support 1080p to the point that there is no need to **** mind about how fast particular video player and choose one solely based on convenience of use and price...

Never tried 1080p on my Desire. 720p was fine, including 720p videos taken using the camcorder in CM6 (720p wasn't in CM7 for some reason).
I haven't even tried any 3rd party players from the Market on the Sensation yet, everything so far has been achieved with what comes built into the phone (ie. just Gallery).

Camcorder 720p clip are H.264 720p Baseline. 1st gen. snapdradon ( QSD8260 ) can play 720p Baseline profile.
but most of 720p/1080p movies are H.264 High profile level 3~5.
If file format is MP4(H.264+AAC), stock player can play .
Many of HD movies are MKV/AVI format and audio codec is AC-3(5.1ch) or DTS or Flac.
ffmpeg base player can not play HD ( 720p/1080p ). Decoding & rendering need too much CPU power.
If you want to play HD(with DTS/AC-3/FLAC + MKV/AVI) clips, use diceplayer.

Flash streaming video is pixelated, is yours?

When watching streaming videos from websites is it pixelated on your device? I'm watching anime and dramas on sites and they are blockish looking. It did this on my pc back in the day with older divx/flash plugins as well.
(This isn't the case for sites like Youtube, etc. It is mainly on the anime sites).

It's because the resoluton of the video you are streaming is not high enough.

then the problem are with the videos you're watching. they must just be low-quality.
also, some sites stream lower quality videos depending on your connection speed, that can another thing to consider.

It's not those kind of squares that result from low quality vids.
The vids look fine on my desktop running at higher res.
These are little tiny squares.

try posting a screenshot.

The TF is terrible in playing flash videos via browsers. Check the videos on this site, for instance:
http://www.ittf.com/ittv/
I also cannot play any flash video on the espn3 site on the TF. On my other computers, all these videos play smoothly. Even on my Gingerbread Nook Color and on the 2.2 HTC Thunderbolt, they play smoothly.
Apparently the Xoom or the Galaxy Tab has no trouble playing flash. So something's wrong with the Asus implementation.

I watched a vid on that site on my TF and my laptop..
Those videos are low quality and the TF looked better than my laptop..(it was smaller)
I've streamed videos from youtube and vimeo and they look great. it all depends on what's going in...to determine what's going out.

yes I found it pixelated too. tried dolphin HD and the video quality is worst than playing it on stock browser. I downloaded the video file (using firefox plugin), the quality is much better played on stock video player. so I presume the flash player used by the browsers are set to certain quality.

Has anyone tried Ustream? I want to use Ustream but no joy,is there a fix for this?

What's the problem with Ustream ? It's working fine here.

I get pixelation when viewing ad videos on websites. Doesn't bother me at all.

The Tegra2 does seem to do less deblocking that you might get on a system with more spare CPU power. Nothing to do with "pixelation" though.

[Q] Can the TF really play 1080p videos?

Not that I would really notice any difference between 720p and 1080p but I think there might be some misunderstanding that the TF can play back full 1080p video (1920x1080). Or at least mine can't without encountering serious lag.
I can't play 1080p on the browser YouTube without lag. Also the YouTube app doesn't let you chose between 720p and 1080p so I'm guessing it only plays 720p. to make sure it wasn't a browser problem i download a full HD video (www[dot]digital-digest[dot]com/movies/Limitless_1080p_Theatrical_Trailer[dot]html) and as expected it played with a lot of lag. Can anyone else check on that too?
Thanks

Wondering the same, I hope there is a solution for this problem, Otherwise it may be false marketing/advertisement which would be very sad fact for us as TF users indeed.

So I tried searching for an official quote stating that the TF can playback 1080p video and the closest i came was this line from ASUS's website-
"A 5MP rear- and 1.2MP front-facing camera can shoot and record HD video, which can be played back in stunning 1080p."
Even here it doesn't state clearly where exactly the video can be played back. Nowhere else does it mention that the TF can playback 1080p. I think it's just clever marketing on their part but it does lead to general misinformation about the product.

Why would you want to play 1080p content if the screen only can handle 720p anyway?

Hdmi out to a tv is what comes to mind.

The transformer will do 1080p resolution out to a TV or monitor, but I do not think it is capable of playing true HD videos such as the Limitless trailer you listed.
Mine does play youtube in HD very clearly with no lag.
but I have put a HiDef MP4 video on here and attempted to play it and it was choppy or didnt play correctly at all.
I recommend AVI files and Vplayer or using a program to change the bit rate of the hi def files and trying to play them again.

Yes it will play 1080p, but it will only play 1080p low profile and only with minimal bitrates. I have made several for testing that play fine using Handbrake, but in reality 1080p over HDMI is a bit flawed at the moment, and the tablet doesn't show native 1080p so since you have to re-encode blu-rays anyway you're better off with a high profile high bitrate 720p conversion than low end 1080p.
I have not tried any of this with 3.2 yet.

While we are on the subject, does 5.1/7.1 also work via HDMI?

1080p will not play (atleast my encodes), while 720p seems to play just fine. I'd stick with 720p personally. I don't use the HDMI out, but I can see a reason for having it, it'd be nice.

I've played 1080p videos on youtube with no problem. I'm rooted and running revolver v1.1.3 (HC3.1) at 1.5 GHz.

Playing Youtube videos is not a good guideline really. Unless you make sure you are using a browser with the user agent set to Desktop and also that your Youtube settings are not set to HTML5. Then manually setting the video to 1080p and testing.

The very first bulleted item at the official ASUS product page previously stated "NVIDIA® Tegra™ 2 1.0GHz dual-core CPU for excellent multitasking & 1080P video playback" but now it states "NVIDIA® Tegra™ 2 1.0GHz dual-core CPU for excellent multitasking & HD video playback". I guess they finally decided to change it. I knew I should have taken a screenshot to prove it back when I saw it.

hd video capabilities vs tegra 3

Hi guys,
can adreno 225 play high profile 1080p h264 videos @ 40 mbs like tegra 3 does?
Here http://www.dvdloc8.com/clip.php?movieid=13599&clipid=4 you can download a sample and try it.
Furthermore , can you play a 1080p youtube flash video ( in browser, not using youtube app), does it stutter???
Let me know...
Thanks

Downloading it for you mate

It is a bit lag...picture wise its great but does jump a bit

ok,
indeed tegra 3 gpu seems better, it is fully capable to play this kind of video.
And what about 1080p youtube flash videos ( in browser, not using youtube app)?
thanks a lot

I dont use the browser for youtube videos, Whats the point ?
I think HD videos looks awesome on this phone, I was watching the SGS3 preview via youtube app with brightness on max.
the colours blew me away... thats what i love about the amoled screen

The point is yotube app doesn't use flash player...in app you are watching mp4 videos ( or other low bitrate codec).
In browser , istead ( with desktop user agent) you'll see flash video videos. I really would know if s4 can play 1080p flash videos....

so the quality would be better in the browser ?? i have default set to use youtube so never tried other methods.
im intrigued now lol.

the quality depends on specific video, but in browser you have a real HD ( 720p or 1080p) and a higher bitrate than youtube app that is designed to work with all phones, even with ones that don't have flash player.
In generally, in browser using flash player you can test the true capabilities of the cpu\gpu,

this http://www.youtube.com/watch?v=_i2RCBa3l-g at 1080p is a good test.
There are scenes at high bitrate ( for a flash video ).
Try it please. tegra 3 is good to play this...

Playing youtube on the browser desktop page is definitely much higher quality than in app. Even the lowset 360p option looks better than HQ in the youtube app. Can you test 720p and 1080p in the browser itself.

ok, Using chrome browser and maxthon browser. the picture quality is awesome, both 720p and 1080p.
using stock browser was a little choppy. as if it was buffering, Which it wasnt

ichrome is not using flash player. it is using html5 in youtube desktop or mp4 in youtube mobile.
in stock brower you are using flash player.
