[Q] Video playback on GN (compared to the Note)

There's a thread over in the Note section about poor black rendering in some videos. Could someone try out the sample on the Nexus and see if that too shows the same artifacts? The clip is here:
http://www.mediafire.com/?53da859r2gu8b8q,p4zi4js5g42uxu4
Trying to determine if this is specific to the Note, the screen, or possibly poor software/codec rendering...

* Bump *

I havent seen any other discussion about this based on the search terms I've used and some people said that the Nexus also suffers from the same issue.
Can anyone perform some testing ?

Use the stock player (HW acceleration mode)
Set the screen brightness on the player to lowest
View in a dark room to avoid any distraction from reflections, viewing this with ambient light actually makes it less problematic.

I've downloaded video from first post but video player refuses to play it, sorry. But i was able to play above posted .mkv file and yes, picture looks pretty bad in very dark areas. I don't think we can change anything, that's how our SAMOLED works.

Thanks for trying the video above, other SAMOLED devices display it video w/o any issues.. Like the Samsung Wave , Galaxay S1 and Galaxy S2.
What bothers me though is that on some Galaxy Note's with the very same settings and scenario above it has far lesser issues.
Im actually surprised this is not covered on the Galaxy Nexus sub forums, maybe no one watches HD movies on a 4.65" screen ?

More feedback from users would be nice so samsung can take a look at this issue.

I have seen this on several videos. I thought it was because of codec but realized did not happen on any other device i had.

Android 4.0 does not have native .mkv support like TW devices. It has the ability to hardware decode because the OMAP4460 chipset can decode it but after the update to 4.0.2 divx support was removed for some reason.
4.0.2 changelog:
Device features
Optimized Mobile Hotspot when used with VPN.
Optimized 3G/4G data sessions for faster response times.
Fixed an incorrect notification that “data was disconnected due to roaming”.
Wi-Fi now automatically reconnects when returning to a known Access Point.
Improvements to special visual effects feature when using front-facing camcorder.
Visual improvements to the lock screen.
Email & messaging
Fixed an issue where some email attachments would not open correctly.
Apps & Widgets
DivX support has been removed, and will be supported in a future upgrade.
Improved audio volume in Google navigation turn-by-turn directions.

Try it with mVideo or Dice player, it should work.

Any of the many good video players should work.
MX Video Player even has dual-core support...

I've definitely noticed this about the Nexus screen. I don't know if it's as bad as the Note or not, but I started a couple of huge threads on android forums (some reference the Note thread, so there may be a circular reference thing going on ):
http://androidforums.com/samsung-ga...ing-effect-nexus-other-hd-amoled-screens.html
http://androidforums.com/verizon-ga...ifacts-black-areas-during-video-playback.html
I would love to know if there are any workarounds or if supercurio will be able to help the Nexus owners similar to what he's doing for the Note.

Youtube Update Version 2.4.4: HD playback now available on capable phones.

Latest youtube app can now play HD on our phones, no more need to use Dolphin for HD on youtube.
Videos play smoothly, though I have had a problem with HD needing to buffer a lot even when I am getting 20 Mbps down.
On the bright side HD content looks amazing on the Nitro's screen.

I was Beginning to think it was just my phone acting up on YouTube. The audio was always fine, but the video never was. I hope this update fixes that.

What do you mean by glitchy?

Downloaded the latest one (fresh install), and I agree with both you Kindawack as well as allstar. Yes, the HD videos look magnificent (just saw the avengers trailer n by God it's gorgeous n super sharp), and yes, youtube can run HD videos BETTER now. The reason I say better and that I agree with allstar is because I still see random stuttering in video play. That is wat allstar meant by glitchy. What happens is that the video framerates fall behind the audio playback and eventually 'jumps/speeds up' to catch up to the audio.
Now with the latest youtube app, the glitch is actually at a minimum and happens randomly. Throughout the trailer, it only glitched on me around 4-5 times and I almost barely noticed them. So I agree this version addresses the glitches. Now the rest of the stuttering falls on the phone itself and properly allocating resources to youtube.
EDIT: Nope, forget it, glitch is still there, in full affect. Just saw another HD video, the new Gorillaz video, DoYaThing, and you can tell from 2D's movement that it's there. He will slightly slow down as he moves, and then sprints back to frame.

Oh he meant dropped frames,not that surprising I got them on 480P as well.

And on top of none-smooth playback it rebuffers even on wifi 40mbps connection...I think Google optimizes it's software only for it's flagship phones (Nexus), until it gets HD display we shall not see any improvements on Nitro....My theory

The Galaxy Nexus does have an HD screen.

Hmmm...then I guess it's due to no optimization from LG side? Perhaps the lag we experiencing in the UI is related?

why don't you guys just use opera and flash 11? I use it all the time and get no lag and it works great and fast. Also opera or maxathon are the smoothest browsers for non ics phones right now. There is virtually no lag while scrolling with these 2 browsers.

i dont get any rebuffering issues though. runs smoothly on both wifi or 4G/LTE. Other than drop frames, everything else seems fine.

How much does JB improve browser experience?

If anyone's using jellybean already, can you comment on how smooth browsing is? Has pinch to zoom and scrolling speed/choppiness been improved?

Pinch to zoom is significantly better. Scrolling is still "choppy" as you put it. The biggest improvement is the quick controls which is under labs in settings.

I use Chrome, so the browsing experience is the same. Not sure why you would want to use anything else since you can have it sync EVERYTHING between desktop/laptop/tablet/phone/etc. and also share tabs between devices as well.

Zoom is really smooth! However, I cannot confirm the choppy scrolling. The improvements are not too large overall, but on the other hand, nothing got worse either. ^^
A major drawback for some users might be that flash support ended with 4.0.4 and will not be extended beyond that by Adobe. If you are browsing a lot of flash sites, this may of course significantly affect your browsing experience.
On the other hand, with flash being disabled once and for all, this is a great opportunity to switch to Chrome, which has just grown out of the beta phase as of this week (...coincidence?). I like the Browsing experience with Chrome much better than with the stock browser (which applies to both 4.0.4 and 4.1).

Chrome is awesome. The best feature being the convenience of sync. It should be made the default browser. I would love to see the quick controls added to chrome as well.

What new options did they add for the quick controls? Does it rival ICS+?
Also I can't use chrome till it can hide top bar, has quick controls, and has invert color option. Does chrome have those yet? Plus chrome is always choppy for me compared to stock browser.

Adobe flash player officially does not work on Chrome Browser for android 4.1 Jelly Bean... This to me is not improving browser experience even with all the other enhancements of the 4.1 browser...

Wait a second...choppy browser? The stock browsers in both ICS and JB are extremely smooth. The ICS browser introduced cached scrolling and zooming like in the iPhone, bringing iPhone like smoothness to the browser.
Runs butter smooth in both my Xperia Play ICS install and on my Galaxy Nexus, not sure what you guys are talking about.
Chrome still doesn't support this, so it can be choppy on large websites, but it's an add on browser, not stock.
Edit: I just tried the newest build of Chrome and it has been bumped up to the 60fps scrolling too using the cache tech. There's more clipping than the stock browser but it's now buttery smooth, even on complex sites using Jellybean

Chrome never supported Flash, even in ICS

I went back to AOKP Milestone 5, Chrome experience is much more fluid on that. Scrolling is perfect with Franco kernel m3. Hoping Jellybean gets there soon.

Yeah choppy. I said CHROME browser is always choppy for me, but stock browser is always smooth. Plus stock browser has more useful options I need which chrome is missing.

Guess you'll have to stick to playing Farmville in a different browser then. Also, Adobe stated that Flash is going to stop being supported for mobile devices, and will not support JB outside of early support over the next month or so.

I never used the browser or browser + on ICS because I found it convenient to use Chrome with all its syncing capabilities. With the new quick controls, I realize what is missing from chrome. The controls in JB browser are much more enhanced and as a result much more useful. They definitely rival that of the Browser +'s. Check out this video to look for yourself:

Wow that's pretty useful. My current setup has 3 rings of quick controls in the browser which takes up the whole screen when they appear. Looks very efficient and useful in JB.

Dolphin HD Pinch to Zoom Appears Broken ATM in JB
Dolphin HD pinch to zoom is currently not working in JRN84D / 4.1 (MoDaCo ROM) which paralyzes the browser usability.

I don't have a scientific testing method, but overall it feels better, more responsive, quicker. You only really notice when you jump back to an ICS ROM.

Tab S 10.5 YouTube Video Stuttering

Hi guys, I recently bought a galaxy tab s 10.5 and I'm having issues with video playback in the native YouTube app. Basically every 5-10 seconds, I would get a micro stutter, as if the video is slightly jittery. It's definetely not buffering as the video has loaded well ahead already too.
I am using the samsung stock OS so 4.4.2 and I have installed all the latest official updates for both the OS and the Youtube app.
I have also tried a factory reset of the machine, clearing the cache and updates for the Youtube app and reinstalling. I've also tried forced GPU rendering and turning off hardware overlays in developer mode
Does this indicate there's an issue with my hardware ? It does not happen when i stream videos from my PC over wifi or any locally downloaded videos. Any help would be appreciated. Thanks.

Hmmm, never had this problem with mine when it was on stock. I usually had this problem when I underclocked my cpus and all that or when I am using to many appps.
The only thing I can suggest is use another app (viral popup https://play.google.com/store/apps/details?id=com.Mata.YTplayer ) or take it back to be safe.

Thanks, yep the youtube videos would stutter even when i freshly restarted the tablet so nothing else really is running in the background. I have tried the viral popup app except it seems to play at a really low quality setting, ,ie 1080p is not available ?
Is there anything I can test to see if its a possible hardware issue ? I ran the Antutu benchmark and got 37k which seems in line for what's expect from this tablet. Does this help rule anything out ? Thanks.

Check processes, there's probably something in the background.

I dont think so. When you play games does it lag too? Ex real racing 3 etc? Because if it cant play youtube without the micro lag, that may affect other apps. I dont get any lag while I was on stock.
If any other apps lag while playing (not on loading screens) then it may be an issue. I never had any micro lag on mine so it may vary on how you see it. Of course we have custom roms that are way smoother (CM12) but I am unsure if your issue is hardware related or the way you see it. Hope this helps!

I got youtube stuttering too for months on my TabS ST800, I tried every tricks in dev options, nothing ever changed .
But one day i tried the CARDBOARD view in the YouTube app options and then return to normal 2D view.... motion became butter smooth up to 1440p60, for any video! If closing youtube app and restarting it, it is stuttering again, until opening again the cardboard view.
Here is a test video I used to validate stutter-free playback :

Good luck.

You, sir, are awesome!!! I had this problem for the last couple of months on my Tab Pro 10.1, tried everything to eliminate it. Going back to Stock or GraveD rom was slightly better but not really smooth either. I was beginning to lose my sanity switching back and forth between CM11, CM12.1 and stock-rom, trying different developer-options but was not completely satisfied in the end. This cardboard-step is a temporary fix i can definitely live with. But I'm surprised that not many people seem to be effected by this stuttering or they simply don't mind at all. Hope that google is going to fix this shortcoming in the near future but meanwhile...Thanks a ton mister :good:!

I was so happy too I spent a night watching again many videos I love ! I'm glad I could share that little joy !
To answer your question, it is a shame that people are suffering from the belief that "online" videos on computer, tablets or phone *must* somewhat stutter. Well ... even trans-galactic communications in Star Wars/Trek and other sci-fi movies are depicted with stutter and even analog (!) video sync and lines issues (in 2150!!). Stutter and other digital disorders have been imprinted in the modern culture because not much effort was given to understand (and implement) that we human are analog creatures requiring a natural constant flow of sound and light, not a "best effort" variable low frame sample rate due to "unavoidable" system interrupts between storage, cpu, gpu and screen. Remarkably, Apple hardware/software was always close to perfection due to their close collaboration with the computer graphics industry for tv and movies..
It is indeed so much enjoyable when colors, contrast, motion of a clean picture hit the brain which then do not have to interpolate, filter dynamically and overcome an unpleasant stressfull and therefore tiring "motion picture"
So far only Sony with its X1 graphical processor in TVs is IMO able to achieve a minimum of digital artefacts while interpolating and displaying moving pictures. HD was a attempt to increase resolution (but we lost many qualities that the oldest of us enjoyed with CRT tubes). UHD must bring "better pixels" back with constant higher frame rate, higher pixel resolution and higher color resolution and dynamic range.
I hope to say bye bye soon to "flicks" = flickering judderish stuttering color-ish moving pictures.

Snapdragon S10/+/e owners please read: Possible bug with lag and stuttering

Guys, before you reply with any feedback, please read the following post and links in full. It would also help if you posted details of your device like the following, which is mine:
Model: SM-G9750 (Hong Kong S10+)
Build number: G9750ZHU1ASF1
Completely stock, no settings changed
Only YouTube Vanced installed (for testing purposes)
Click to expand...
Click to collapse
Summary: An intermittent stutter or lag (most notably during fullscreen 4K HDR playback, in my case) which only goes away when you activate certain screen recorder applications like Game Tools or AZ Screen Recorder.
Below is a list of posts that highlight this problem that I and a few others are experiencing. The common denominator here is the use of a screen recorder, which removes any present stutter or lag.
https://forum.xda-developers.com/s10-plus/help/lag-stutter-overall-choppy-t3914381
https://www.reddit.com/r/galaxys10/comments/btwfbl/anyone_experiencing_stuttering_or_frame_drops_on/
https://www.reddit.com/r/galaxys10/comments/b79cw3/is_snapdragon_really_that_much_worse_than_exynos/
https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/ (video evidence of problem)
The following two are from myself. My problem is that all 4K HDR content (could extend to other formats also but I need to do more testing) is stuttering or dropping frames. Screen recorder on and boom - it's smooth.
https://www.reddit.com/r/galaxys10/comments/ch172q/snapdragon_owners_does_this_type_of_video_play/
https://forum.xda-developers.com/s10-plus/help/sm-g9750-video-playback-throttled-t3950757
The lag returns as soon as you deactivate screen recording, which suggests that this is either a bug with the CPU or GPU not being optimized or boosting its frequencies properly, leading to these stutters.
I've put Snapdragon in the title as these posts all appear to be from Snapdragon owners, whether it's the US or HK variant. I don't recall ever having this issue as a last generation S9 Exynos owner. If you are an S10/+/e Exynos owner and encountering this issue, you could still try using your phone normally, with a screen recorder active and then without, to see if there is any performance gain (as crazy as it sounds, it might actually make a difference).
Below is a test I'm using to demonstrate my problem. It involves installing apps (namely YouTube Vanced and either one of two screen recorders I've tested it with), so it's not the most convenient. If I find a better method, I will update the post accordingly.
You will need YouTube Vanced. I'm suggesting Vanced because the original YouTube app doesn't let you view at 4K resolution.
Firstly, open Vanced and tap the account icon in the upper right. Go to settings, Vanced settings, Video settings and then toggle Resolution Checks to ON. Refresh and restart the app.
Now open Game Launcher, tap the three dots in the upper right > Add apps and add YouTube Vanced to the list. We're doing this for the screen recording function which I'll mention later.
Note: if you don't have Game Launcher or Game Tools, you can try AZ Screen Recorder as an alternative. Nice Shot does not work.
Once that's done, here's a 4K 60fps clip for you to try. It should be easier to perceive any hiccups with the higher frame rate. Please set the resolution to 2160p (tap the three dots in the upper right) and watch in fullscreen / landscape orientation:
https://www.youtube.com/watch?v=LXb3EKWsInQ
Panning shots work best. For reference, see points 0:19, 0:46, 1:48, 2:14, 2:42, 3:04, 4:11 and 4:41 in the video. Does it look like it's stuttering or dropping frames intermittently?.
Now, swipe up from the bottom of the screen to show the navigation bar (you need the navigation bar enabled to use the recording function) and tap on Game Tools, which is the leftmost button. Tap Record.
While the screen is recording, are the stutters now gone? To my eyes, the video plays back perfectly while the recorder is active.

Well if you have a better solution then I'm all ears? I left a similar post in the Q&A section and didn't receive a single reply. So I thought I'd post it here instead since it's more active.
We're still in the "Guides, News, & Discussion" forum, right? And technically this could even be a guide since I posted a solution, no matter how useless it may be

What resolution are playing those videos at?
I played the Peru 4k 60 @1080P one on youtube and it was great. Then played the same on Vance 1440 @60fps and it was same smoothness.

[email protected] is where I experience constant stutter. You will need to override resolution checks in Vanced to watch at that resolution: Tap the account icon in the upper right. Go to settings, Vanced settings, Video settings and then toggle Resolution Checks to ON. Refresh and restart the app.
Don't forget to try it with the screen recorder on please, to compare if playback is smoother.
Just realized you're on Exynos, so the issue might not pertain to you, though there's a chance I might be wrong in that regard. Thanks for testing though - more feedback is always welcome :good:

Lizard brain saw the GB flag and assumed you were an Exynos owner - my mistake! So you debloated your phone huh? Is something like Nice Shot or AZ Screen Recorder an option?
Here's a link for anyone wanting to download and test locally:

or
http://www.mediafire.com/file/dzndenwhk6ddboc/COSTA_RICA_IN_4K_60fps_HDR_%28ULTRA_HD%29.mp4/file
You will also need a screen recorder of some sort though, that's the most important step. Here's a few:

update: Nice Shot doesn't work for this test.
Appreciate anyone else willing to try, of your own volition of course. Doing this purely to raise awareness on the issue and gather feedback.

I just tested this using the supplied download links for the actual video and AZ screen recorder.
In all honesty I couldn't see any difference between the video running with or without the screen recorder recording it. They both looked smooth. I was using the default video player to watch the downloaded video.

That looks like the Samsung video player, but no matter since the problem persists across other players too. MX Player in HW decoding seems to be the worst performing one for me.
Did you watch in landscape fullscreened? I keep forgetting to add that detail. If it was the same regardless, then I guess that removes the US Snapdragon from the equation. But thanks for taking the time to test, much appreciated :good: People probably think I'm bullshitting but once I find a concrete way to show what I'm experiencing, I will update this thread.
So far I've only had confirmation of this problem from two (yes, only two but it's still something!) other people, and they also happen to be owners of the HK S10+ variant like myself. If there are any other HK owners out there, I could really do with your feedback on this too!

Yes , I watched it in landscape mode, even compared the first few scenes where the camera pans etc with screen recorder on and off, couldn't tell the difference.
Maybe you could film the issue with a camera for us to see ?

Mx player with hardware decoding is no problem, smooth as butter. Snapdragon U1.
What does YouTube report with nerd stats turned on for the dropped frames line?
No offense but your premise is flawed at best. All you have done is made a subjective claim backed up by no legitimate measurable evidence..
Having people install screen recorders and play videos is not 'testing' anything..
Best of luck

That's been tried by someone already but the thing with these cross-comparisons is that they aren't conclusive enough for some people. For me it's crystal clear because I already know what to look for.
Here, this link was in the OP: https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/
One on the left is HK S10+, Exynos S9+ on the right. Make sure it's in [email protected] so it's as clear as possible.
The most obvious thing is that the scrolling is laggy on the HK model, but if you look closely, the video is stuttering too (look at the zooming out shot at the beginning). Exynos is completely smooth.
Stuttering video is a big no-no for me, really should not be happening on a phone of this spec.

Okay fair enough my test isn't the most thought out, but if you have any better suggestions on how to demonstrate the problem, you're more than welcome to provide them.
Stats for nerds doesn't show dropped frames, so it's likely that any FPS monitoring software would be useless too.
No it's not a subjective claim because if you read through the post and links in full, you would see a number of people confirming the problem. Doesn't matter how few, it's still an issue that shouldn't be ignored.
And one of the links has evidence in the form of video comparison: https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/ please watch it @ 1080p60 on something larger than a phone screen.
The one thing I should've probably clarified is that I'm on the HK S10+, but those links indicate that US variants have a similar issue too. If yours doesn't have it, then cool, you're good to go :good:

So now we're talking about the scrolling when the video is played minimized like the reddit video? Yes mines like the same laggy. But the video itself full screen is ok.

Not the scrolling specifically because that's related to the problem. For me the scrolling is laggy AND the video stutters. Are you sure the video is completely smooth? It might seem so but on mine there are frame drops present - even if it's very minor, there should be none at all.
It's best to compare with another capable device side-by-side with your own eyes, as no video recording will be able to demonstrate this clearly enough. There's also a chance that some people aren't sensitive enough to stutters and might not even be able to perceive them (I'm not saying you are, this could genuinely not be happening on your device).
And even if the video doesn't appear to be stuttering to you, shouldn't the laggy scrolling be enough cause for concern? A last gen phone is running smoother and that's not acceptable. Don't settle for mediocrity guys.
edit: before anyone questions the absence of screen recording in that video, the person who uploaded it has another post on reddit where he mentions it fixing the problem.

Watching it at 1440p on native YouTube app it seems the scrolling is smooth. But on Vanced @2140 not so smooth scrolling. Probably the Vanced app or cpu etc binning on the snapdragon.

I don't think it's the app or hardware because once I turn on the screen recorder, playback is perfect (landscape). I'm no expert on this but a logical guess means there's a frequency boost while the recorder is active, removing the stutters.
If I could find a less ****ty workaround that does the same, I would be okay with it, but there isn't

No lag here. My phone has been flawless. SD
