[Q] I/O-speed improvement

So, the I/O-speed often is the bottleneck for the tf300. I knew this already, just like the most of you probably. It didn't bother me too much, as I didn't have a lot of issues because of it.
Lately I did start to encounter problems with it, because I started to use my tablet for streaming video. The result is that I can watch about 30 seconds of video, have to wait 30 seconds while the device is buffering, can watch another 30 seconds of video, wait for buffering again, and so on.... It seems the device is not capable to buffer while playing video. Well, you can imagine I don't have the patience nor the wish to watch any video till the end under these circumstances.
As I see and know that the network connection is just fine for streaming video capabilities (it works fine on my laptop and phone for instance), I am pretty sure the problems I have on the tf300 are due to the I/O-issues.
Now my specific question is: is there any solution or workaround to avoid lagging video streams because of these I/O speed issues?
And on a wider spectrum: Is there any way to improve overall I/O-speed performance on the tf300?
Any help is much appreciated.
FYI: My tf300 is rooted, but not unlocked. I prefer to keep it this way, unless there is no option at all to get around these issues without an unlocked device.

i/o can be a problem but this is a bit extreme even for a tf300, what kind of bitrate has that video? raw 4k?

:laugh: No, it is not raw 4k.
The video-stream has a bitrate varying from 0,8 to 1,5 Mbit/s.

Those youtube videos don't play well on my tf300 either, I always have to 'untick' the HD or HQ button in the videos to play them smoothly.
Do you run stock Android with latest OTA updates on your tf300?

I do run stock indeed. Only rooted.

Well, I'll give it a try by completely factory-resetting my tf300. I doubt it will make a difference, but without trying I'll never know.

Resurrecting I see this thread was never resolved, and if the streaming was addressed elswhere I couldn't find it.
Picked up this tablet recently, 4.2.1 rooted stock. Youtube streaming is unwatchable in HD - not enough buffer, but handles HQ or lower fine. Can stream 1080P fine on my desktop, and HD fine on my Razr I and Arc S. Which makes me question, why the inability to cache enough of the video on the TF300T?

Learn from linux
Hmm I stumbled across a few articles, how to improve linux for netbooks. Some involved lowering the writeback to get better I/O-speeds while batterylife gets improved. Maybe one could figure out how much of this applys with Android and the eMMC drive in our tablet and tweak it accordingly.
Best regards.

I had no issues with surdu_petru's overclocked kernels, got around 10000 i.o (sio scheduler) in quadrant, in saying that that kernel got me a score of 7100 on quadrant overall which must be close to the best for tegra 3s?

Issues with camera when recording videos.

I have issues with the focus when recording videos indoors even when lights are on, outside in daylight I don't have such issue. When I point it on my arm and start recording, it gets all blurry and have trouble focusing even when I'm clicking on the screen so it can focus at the specific area. When I use pro mode and manually focus then everything is alright but that can't be the solution as I'll have to adjust it all the time.
I installed "open camera" and it works great so I don't know what could be wrong with the stock app.
Thanks.

Hi I just logged in because I have the same question. It happens to me when I record in FHD 60fps. It seems to have some filter applied and the blurry effect is so annoying.

In 1080p60fps is much worse and it kinda turns yellowish too. I don't think it's a filter cause outside in daylight its perfect.

Yeah it's true, just tried Open camera as you did and it works great. I can't find any similiar issue on web. I hope it's a software problem so it can be fixed with an update.

Stock app with flash works too, hopefully more S7 users will comment and tell us if they face the same problem or not.

Anyone?

Bump

Yes i just noticed this as well

This is a known issue with 60fps recording on s7. Phone can't focus correctly while video recording in 60fps. It's there from day one so I doubt it will change in the future.

I guess we'll just have to use UHD or normal 1080p recording

How to Fix Video Stutter

Has anyone here experienced any video stutter when recording? I noticed this in my XZ when recording 30fps Intelligent Active steadyshot. I'm not on Stamina Mode so I don't know what's causing it. I'm on the latest version of Nougat btw.
Sent from my F8331 using XDA-Developers Legacy app

Yes I also have the same problem. Is there any fix for this problem as it is very annoying.

I have this also on latest Nougat :/

Same here both USA and Japan version

Same here. Anyone tried factory reset?

Is it like severe stuttering or like a lower framerate viewfinder than it should be? Like it's not smooth motion? Because if it's the second one, I see it as well, but mostly when Object tracking is enabled. I usually shoot in 60 FPS so it's less noticable. That being said, while shooting, there is some stuttering in both 30 and 60 FPS, but when I watch the videos they are fine and as they should be, it's only the viewfinder that stutters sometimes a bit, I guess because of the processing. Disabling Auto scene mode might help as well.
It might be that Sony lowered viewfinder framerate to reduce cpu usage and battery drain while recording.
Do your videos also come out stuttering or are they fine when watching them?
Same is in recording 4K, there is some stutter while recording, but the video comes out smooth and fine.
This issue seems similar to stuttering issue when watching some movie rips, for some reason some lower resolution lower bitrate movies stutter, but watching FullHD and 4K works fine without stuttering, but while doing that all cpu cores throttles up and get utilized properly. In the movies where it stutters, only two cores get bumped up clock speed, while the other two mostly stay at lowest clocks. It could be a codec issue, where it doesn't use all he cores as it should when it should. https://forum.xda-developers.com/xperia-xz/help/platinum-xz-rev-2-0-video-playback-t3576686
In general, lately, Sony has been heavily optimizing their OS in favor of preserving battery life, but in some cases they went too restrictive and conservative to a point that the chipset isn't working at its full power when you need it to.

I noticed it too, first few seconds of taking a video then it becomes smooth again...

Right. Upon further testing, I noticed it happens more ofthen in lower light conditions or when switching from low light to good light when it changes exposure and brigthness. It's mostly OK when in good light.
So it seems like the processing of the video recording, the auto adjustments of the scene and object tracking is causing some framerate drops in the viewfinder, but it really doesn't concern me as long as the final video turns out smooth as it should.

Weirdly my videos turn out laggy, i took 2 videos last week on the beach (excellent light), both of them lag when played back just the first few seconds exactly as it showed on the viewfinder while taking them.

I have this as well on my stock XZ Dual (F8332)
Hoping to find a fix
on my current firmware (41.2.A.7.65) the issue is less prominent. But I still get a little stuttering at the beginning of video's

Hold your hand still, no issues here.

This is not a constructive comment and is not at all helpful.
There is a bug in the current Nougat build causing stutter/lag when recording video. I am experiencing it on my Xperia X Performance as well.

Has anybody done a factory reset to see if the problem goes away?
Clearing the cache did not help

It's not. Unfortunately.
Wysłane z mojego F8331 przy użyciu Tapatalka

Upgrade to 41.2.A.7.53 solved it for me.

I am on 41.2.A.7.53 and I still have the issue (in fact I started noticing it only since the last update)
F8332 - CDA:1305-2218 Customized HK
Stock software, no root, no BL unlock, etc.

I have the phone for more than 6 months and I had no problem with videos until recently when I went to vacation and my vacation video got ruined with lag

I'm on the latest update and still experiencing this stuttering.
Turning off steady shot did seem to help

If video is on SD try to record on phone memory. Recordind on SD is slower than on phone memory.

Does anybody still suffer from this? It seems to hit only a limited amount of users
(after several updates I still have this issue)

Camera quality help

The camera takes great still shots, but even the smallest amount of movement results in terrible blur. Is this normal?
I just cleared the camera data do I'm shooting on default settings.
Here's a picture of my child simply smiling and jabbering to me. Is this normal?
Id say if I take 10 pictures of her, only 1 is clear (caught betwen normal bodily twitches and stuff)
With this camera like this it'd be near impossible taking pictures of my dog unless it was sleeping. Is this your experience as well?
Are their pro settings that make it better?

Yes because no OIS ?

normal after emui 5 terrible optimization & shutter lag...emui 4.1 didn't have this shutter lag problem
our terrible sluggish processor don't even support google cam which has zero shutter lag

yeah the EMUI 5.0 sucks in this regard, at-least and strange part is, Huawei was not even aware of this unless this was reported to them in recent fan meet in India. Hope we get fix soon for this.

I hope at least they fix it now after reporting in fan meet... No word upto now is disappointing... Not even a single update in past 2 months after b340?? added to this, wapp notification lag... It made me put wapp in deep sleep using greenify & open it once in a day & sync messages when i don't/can't use phone for 10 minutes...

I knew some people from our group that uses Huawei GR5 2017 (Honor 6x) and they have observed that the quality of the front camera (in photos and videos) are a bit grainy (or maybe too bright to be true). Build number is on B370. Anyone experienced this? Or any workaround? Thanks.

Disable the beauty mode and it should be bit better. This over exposed thing has been notified to honor officials and they said they will inform their R&D to resolve this

The issue was not limited to the images taken using the front camera. It includes the video quality of the front camera - which doesn't have a Beauty mode.
They received an update just now, but it is just limited to security patches and voLTE and they've advised me that there was no fix on the camera that came with it.

Hello ever since I updated to B370, the star track mode is not working for me anymore. Everytime i try to capture, it will all became white (overexposed). It used to be good when I was in B360. What could have happen? Or what could i do to fix it?

Replace Thermal paste? (with liquid metal)

Hey there :]
My trusty OnePlusOne is unable to properly record anything above a 480p video without dropping frames. It gets really bad with 4k especially, where after 10 seconds it drops below 10 fps.
The reason is the CPU hitting 75°C under load rather and throttling to hell. Below 800mhz with 4k recordings even. (With any recording app BTW)
Can this be improved somehow?
I already succsefully replaced the battery and wondered: Can the Oneplus One be disassembled to reveal the CPU die? Would replacing the TIM with Liquid Metal improve things?

Have you tried a software approach first? New ROM or simply a factory reset. Underclocking would be an option. I wouldn't recommend recording 4k in the first place. It creates huge files and there's no real discernable quality improvement. It's a 2014 device, 4K wasn't even a thing back then.
I doubt it would be feasible to make any cooling improvements on the hardware. I also replaced the battery on a Bacon before and didn't notice much repairability. I guess it could be a fun project though if the phone is disposable to you.
If you really want to know, I'm sure this will answer most of your questions: https://www.ifixit.com/Teardown/OnePlus+One+Teardown/26484

As recommended I will switch to this one tomorrow or the day after tomorrow: https://forum.xda-developers.com/on...-unofficial-optimized-lineageos-14-1-t3693223
So far I have been running TugaPower 58.0 (Android 7.1.2, Lineage OS 14.1) 3.4.113-Franco Kernel.
Because of loss of Manual Focus + RAW + 64s exposer I stuck to such an old version of Android. Newer Version always broke manual focus (due to deprecation of camera API v1 or something), which I can't live without^^ Hope bacon camera will work on Android 10...

well i was gonna consider mentioning a rom only cause i figured you were on a older build, cause the previous member had mentioned that our oneplus dont support 4K, and it does i just wanted to help you point out even regarding back to 2014, you just gotta know what your doing and looking for.Besides i wanted to stop you before you opened up the oneplus, unless something is broken and needed to be replaced.It mostly involves a rom that has camera bugs, and ive been on almost every rom we have for us and nothing gives the best superb to anything except the one i had ported over to us.But by now lineage 17.1 is still in buggy stages, but im sure your 4k issue will be resolved.

Well technically, they do, even if the image itself is barely better. Using a denoiser like NeatVideo does a superb job at producing a crispy clean 1080p out of the noisy 4k, by denoising with the noise pattern at 4k. ( As explained here https://youtu.be/2oUFiNb7DpM?t=190 )
That's the reason I love recording in 4k, even if the device does not actually give better quality.

Switched to Android 10 LinageOS 17.1 with this ROM.
So happy to see fully manual ISO, 64s second exposure, RAW Photos AND manual focus all working fine.
I'm really surprised to see core parking happening apparently. With the Android 7 ROM on the home screen every core downclocked to 200mhz, but I don't recall them being marked as parked. All the other cores are parked and only 1 with 200mhz is left. facinating.
Video recording is indeed better behaved. But 4k is still a no go. After 20 seconds I reach 75°C and the throtteling starts. But it takes another minute, until the cores drop below 1Ghz. Gotta stick with 1080p. Luckily this seems to work now without frame drops. It takes 1 minute of 1080p to reach 75°C, but only 3 Cores are under load, as opposed to 4k with 4 Cores. The throttling is only mild and after 2 minutes the video still has no frame drops. 1080p it is.
