[Q] Video glitch

Hopefully the powers that be don't do a DMCA takedown on my youtube video, but I've uploaded an example of a video playback glitch that regularly occurs on my device. Does anyone else see this on their Note 10.1 2014 edition? Very annoying... SM-P600, 32GB, USA version, MK1 firmware. Not rooted.
http://youtu.be/gU6x1CLGa8E

So far, I must be in the less than 1% that have experienced this problem...

you didn't include any info on the clip. audio codec, video codec, bitrate, profile, etc. what videomplayer are you using. is the glitch repeatable at that exact frame each time?

You can be sure that when somebody else had such problems, you will already find it here in the forum. So, no, never have such an issue. Also not over the network.
And, as mad squabbles already wrote: For more we need much more information.

The movie was downloaded from Samsung Hub to the device. HD quality. The videoplayer was the only one that plays these movies (to my knowledge): The stock Samsung video player. The glitch is not repeatable at exact locations. I can go back and rewatch the same clip and it will not appear, which says to me that there is not a data corruption problem. It seems like an I/O or "interrupt" problem to me. I've run Androbench on the device and I get as good as or better than the Anandtech benchmarks for the device.
This type of glitch occurs on any kind of move I play, including those I put on the device (mp4, etc). For the ones I have put on the device manually (not through Google Play or the Hub), I've tried the following players: Dice, MX, Archos, and the stock player.
In all other respects, the device works flawlessly: no lag to speak of (except for the occasional stutter on the notifications pull-down, which seems to be the norm). It doesn't crash randomly and battery life seems normal (no less than 7-10 hours of screen on time, ~4% drain overnight. The only thing that I have that probably isn't too common is that I do have MDM software installed (MaaS360) so that I can sync with my employers Exchange servers using TouchDown.

Normally I would expect that you have an background process which got more attention from Android then your video player. This can be anything. Did you have this issue also after a directly after a restart?

Yes, I have the issue immediately after a restart.

I just removed MaaS360 and rebooted. The glitch remains...

Factory resetting now. Will report back when I get it back online. I'll test video before installing any third party apps...

And.....it's still glitching after a factory reset.

First thing I noticed was that this scene is similar to super Mario live action movie
Second, this glitch can happen when you read from a slow SD card or can be reading and writing at same time, for example downloading from torrent or installing apps and playback movies from same location.

Indeed. However, movies are playing from the internal memory without any other significant activity going on. (no D/Ls, etc. just normal device behavior that is native to the OS) going on in the background. I also have played video in airplane mode...

and the media scan which have issues with scanning some files. Maybe you check which processes are running in the background?

There is always *some* process running in the background... I have cleared all other applications while playing a movie, but really, should this be necessary? (Problem still remains) I've tried playing movies without any non-stock apps installed. Problem occurs. I've tried freezing as much bloatware as possible without rooting before installing third part apps. Problem occurs.
What I would like to explicitly know is this: has anyone rented a movie from Google Play, played at least 30 minutes straight while doing nothing but watching the movie, and saw any stuttering whatsoever during that 30 minutes. I can live with it if it is a suboptimal experience due to firmware (I'm on MK1, btw) if this is "normal" for this device. I could only hope that it would be fixed in a future firmware update if that was the case. However, I have a strong feeling that if I sent this in to Samsung, they'll fiddle with it for 10 minutes, see that it "seems" to be fine (except for this glitch, the device performs completely as-expected for an Android device), then it be returned to me with no action taken. I can live without this thing for a few weeks, but it will be extremely annoying if nothing is actually done about it. Given that this glitch is not reproducible on command, I fear it will be an ongoing thorn in my proverbial behind. Unfortunately, my return window has expired or else it would go back in an instant.

Used Kies to download and reinstall the MK1 firmware in case one of the OTA updates were corrupted. No joy. Still stutters. Samsung Live Chat help of no use. I expect a call or email from them telling me to send it in in the next 3-5 business days unless someone else states that they have the same tablet and sees this problem too, possibly confirming that it is a firmware/device combination issue.

Mmm this is weird, I have no problem with video playback (any supported format by this device)
I have no MK1 but MJ2 and maybe media scanner is working hard in background
Are you using external SD card and / or have many pictures?

Try MX player if you just want to play it somehow
Sent from my GT-I9082

as far as i can remember with pc's.... if video card gets warm or hot, the screen starts to show glitches...

MX player shows glitches as well on movies that it can actually play. i.e., MX player doesn't play nicely with rented (digitally rights managed) movies from Google, which is the primary problem. Perhaps Android tablet users just don't rent movies all that much?

Media scanner isn't working hard in the background as far as I can tell. No to the two questions.

Netflix sucks on FTV

My Netflix sucks big time on my rooted fire TV. Stutters quite a bit. No combination of the video frame rate helps in the settings. What more can I do? I shouldn't have to wipe cache and restart every hour to get smooth playback. Thanks

Netflix has been terrible on aftv. Between the loading to 99%, and "unable to play this title right now" not to mention that atv2 has a much better resolution (for me anyway).
I was experiencing a stutter and I think I switched to WiFi to fix it. Not 100% on that but its working better now.

How'd you fix the two issues you mentioned? Netflix just started doing the same, for no apparent reason about a week ago on my FTV. I found one that here that was said to have the fix, but I've performed each of the steps listed there with no luck. Right now, I'm on 51.1.6.0... I tried the latest, but am affected by the HDCP issue, so had to roll back.

Not sure I did fix it. It may have got better on its own. You could try uninstalling Netflix, clear data 3 times in Amazon video, unplug for 10 seconds. Then it may be beneficial to boot recovery and wipe dalvik and cache partitions. Finally reinstall Netflix.
Mine occasionally doesn't load all the way but restarting the video fixes it.

I don't know what the deal is, but I've tried all of the suggested fixes, but continue to get the same error message. I'll wait for pre-rooted 51.1.6.3 and see if that fixes it.

Sorry. Overall Netflix on Amazon has been terrible for a lot of users while others seem to have no problems at all. They're not likely to provide a fix but it doesn't hurt to contact Amazon. At the very least you'll join a growing list of dissatisfied customers. Problem is Amazon points the finger a Netflix and vice versa. But like I've said before, Netflix has always been fine on my other devices going back almost a decade.

Yeah, the part I don't get is that it just stopped working for no apparent reason. It'd been working fine for months, then all of a sudden I start getting the "can't play video at this time" error (something to that effect). Anyway, thanks for the suggestions and feedback.

If it's any consolation... on 51.1.x.x versions of Fire TV, I never had issues where it wouldn't play video, but I did have studdering and slow/fast issues. On the 51.5.3.0 Fire OS 5 preview, all that has gone away and aside from an issue with 5.1 sound which is solved by putting it on stereo, netflix is working great.

I agree. Netflix performance actually gotten worse on the Fire TV since the latest official stable update. For months I been using it and it was fine but now once again I have issues where the video would freeze up for about 5 to 10 seconds then speed up right away everyone is super fast while the audio continues. Very annoying as I thought they finally fixed it but it came back again. Now I also been getting the "unable to play title" error again too.
I actually started to use my Apple TV 3rd Generation which is connected to Wifi 5ghz channel 36. Loads programs quickly, no stuttering, no unable to, no credit shrinking.

I've learned that having another video app open while trying to access Netflix is what causes the problem. The reason rebooting fixes it is because you essentially flush the FireTV's memory when you do the reboot. If you exit out of other apps fully, you shouldn't have anymore problems. I miss being able to click the Home button when switching between video apps but ever since I started doing a proper shutdown for video apps before switching to the next one, I no longer need to reboot to get the different video apps work.

That message occurs when you have another background application tying up the video process.
Try rebooting. And never use the home button to exit Kodi or any other video application. Quit it properly. And watch out for SPMC, the way it's been implemented to minimize to the home screen with the back button is really unhelpful on the AFTV.
Same goes for using Kodi as a launcher. Don't expect it to be reliable.

Hadn't considered that possibility; however, I don't use an alternate launcher and I always shutdown Kodi properly. Maybe there's something else tying up the video process? I've gone through the 'clear data' process on Amazon Video multiple times, but that didn't fix Netflix. I'll try to go straight into Netflix after a fresh reboot and see what I get.

HACKED? Loud videos randomly playing when screen is off

Hello all.
This question isn't Pixel-specific (as far as I know) but I wanted to ask it here.
For the last week or so, my Pixel XL will suddenly and loudly play an the audio from what I assume is an advertisement video. If I unlock the phone while it's playing, the audio stops and there's nothing to see (other it it seemingly switching from landscape back to portrait).
I tried to delete all apps I've installed in the last 2 weeks, but it still happens.
Any suggestions on how I can solve this issue?

Try running some of the adware and virus scanners. There are some good ones on the play store now. I would suggest you also look at what services are running. Sounds like it is infected.

I tried running two of the top virus and malware scanners, and nothing was found.
Regarding running services, I don't see anything unusual in the list (from Developer options). But then again, I'm not sure what I'm looking for.

Try killing the processes until the audio stops. That should help find out the cause.
Best way to fix would be to do a factory reset.

Sounds like your best bet is a factory reset.

I think it's a Facebook issue. I have same issue only after playing video thru Facebook app.

Audio slightly out of sync when using streaming video apps

Hello to everyone!
I just purchased today the Samsung Galaxy Tab s4, and coming from the Nexus 10 I was astonished by the speed of the device ?
The only thing that bothers me a lot is that whenever I try to watch YouTube, Vimeo, Netflix, Facebook videos or any other streaming video app, the audio is out of sync slightly from the video. This happens only when using the tablet speakers or wired headphones, but not with Bluetooth headphones. On Bluetooth the audio sync if perfect. Also playing locally stored files on the tablet itself, the audio sync is perfect regardless of using speakers, wired or Bluetooth headphones.
I've searched and tried everything I could find (latest update, clear app cache, restarted multiple times, disabled stock anti-virus, force gpu rendering on developer options) and nothing works!!
Has someone else had these issues? Can someone please help me, is there any suggestions? Maybe an app or setting for audio latency adjustment? I'm willing to flash a custom rom on the device (been using LineageOS on my Nexus 10) but can't find anything for Galaxy tab s4.
Thank you!

Any answer someone?

I'm having the same problem, would like to see a solution, because it drives me crazy!!!!

Just replying to say that I have the same issue and it is beyond irritating!

I haven't noticed this at all

No issues here. All in perfect sync.

I already contacted my countries Samsung support about this issue. They said they will investigate it and contact me.
I hope this can be fixed because I basically can't watch videos with that delay.
Also I have an audio latency while watching stock videos stored in the tablets memory.

I'm sending my tablet for service tomorrow, but I've read a lot of horror stories... I hope that I don't end up in one of them

damn, I wonder If I should do the same... I wonder how many people just do not notice it, because delay is very small...

Just want to add to the list, noticed the same and posted on a german forum - but no one even responded there. Maybe no one realizes the issue.
It is best described, as if you have connected bluetooth headphones, which always have a slight delay when watching video. It's not much, maybe 0,3/0,5 seconds.
Please keep us informed about what samsung did and wether the issue could be resolved.

Yep me too
Is subtle, but is there
So I am pretty sure is a software issue
Or many many units are wrong....

I opened yesterday a same topic on Samsung's official forums.
ice0cold, Dedusa23, q173242 and hardpike, if you can write on that thread also maybe it is helpful, someone may see it from Samsung. You can find the link below
https://eu.community.samsung.com/t5...g-streaming/m-p/694759/highlight/false#M25430

I have to say that I did notice this short after buying it.
But yesterday I checked and now seems ok
I did check amazon, netfliz and one movie with mx player
All good now

what about Youtube? I'm still having the same delay.

I thinkni still seeing a slight voice delay

I'm in the USA and have same issue...
I bought my tab S4 as an open box from Best Buy. Audio is slightly out of sync, behind video in most apps. YouTube is the worst, but in Amazon Prime Video it seems perfectly in sync. I went to a different Best Buy and looked at the demo model. Same sync issue as mine! Next time I visit the store I bought it from I will check their demo model.
Hopefully it's not a hardware issue because Amazon works fine. Could be some underlying Android video API causing the problem....one Amazon doesn't use?

Recent update.
I took it to a Samsung service point and they are deniyng the problem.. They say they don't see anything wrong hardware wise and that the delay is so slight that is barely noticeable by them.. I'm going to wait a couple of months and if nothing changes with a new firmware update I'm going to sell it and get a new one. Samsung honestly I'm very pissed with you and your representatives...

I just noticed it again, when watching Netflix.
I haven't noticed the issue in other applications. Will have a look.
My former tablet is the first Tab S 10.1 and this was never an issue.
I will try using BT-Headphones, wich i did not yet try.
Also, I will look at different Apps, but Netflix is most annoying.
It is probably a good idea to submit an error report to Netflix.

Intermittent freezing when gaming/ watching any type of video

Its been a long time since I have posted something on this site. Got myself a RM 5G, its been great so far. Noticed as of late when I am gaming or watching a video of any type youtube, netflix, facebook etc it will freeze for anywhere up to 3 seconds then continue playing.
It might not sound like its a big deal or anything, more annoying if anything. I have replicated this on lte and wifi in multiple locations. First i thought it may of been the android system viewer thing that was happening recently but I dont think it is now. Considering a factory reset to see if this works out.
Non rooted device, just seeing if anyone else has experienced this with there RM's? If so what did you do to fix the issue?
I have a section in this video that I was recording start the video from minute 18:40 and you will notice the lag to illustrate what I am explaining. This would happen while watching videos.
Cheers in advance.
