I often watch a movie or TV serie on my phone before sleeping, but I have noticed that the video payback is not always smooth and there are slight stutters as if the G3 doesn't have enough power to play back full HD high bitrate, particularly in Matroska formats. So whats up with this? I know the G3 is plenty powerful to be able to play without stutter, so could it be some kind of power saving feature holding the cpu performance back and causing stuttering? This is ridiculous to be happening with a flag ship phone! Any ideas on how to fix this?
I assume these are on your phone and not on your network or the web or something. Have you seen this thread?

You could try turning off the throttling (at your own risk).

I will try that and report back, the only strange thing is that my phone does not get warm at all when watching video, so I don't think its a problem with temperature, I usually watch at very low brightness.
I tried turning off the throttling features and it made no difference. I think maybe the stock video player is just not optimized well, so I am going to try VLC and see how that goes.
I'm not sure if this will be of any help, I hope VLC works for you. I use BS Player on my 2012 nexus 7 to play my 1080p bluray rips(at whatever bitrate the pirate scene rips at). I would suggest trying that one and to play with the hardware decoding options if things don't seem smooth with it.

You could try that. May work. The other option would be to turn off the power saving feature LG put in that limits the cpu. It likely turns down for easier frames and then has trouble with frames with more detail, since compressed video is variable like that. I'm not sure if anyone has completely disabled this though, and it may have a huge impact on battery life.
EDIT: Solved by restarting the device.
When playing very large files (h264, 1.5h movie encoded into 7GB file, high profile, 1080p of course) I get high CPU usage in some scenes and dropped frames. Is that too much for Fire TV CPU? Why is CPU usage that high if Kodi uses hardware acceleration? (I tried both libstagefright and mediacodec, they seem to give the same result while software decoding is a bit worse).
Codec info shows no dropped frames, but it's visible that the video is choppy.
Cache is full (although sometimes has trouble filling up - but it doesn't seem connected and is not causing real problems).
Mb/s: usually about 10MBit/s when it happens (doesn't seem that much really).
Cpu usage: all 4 CPUs are over 90% when it happens.
Drop: close to zero, but the video is visibly choppy.
Is this normal?
From specs Fire TV should handle up to 20MBps...
PS. Anyone willing to test those files: http://jell.yfish.us/ - 20Mbps works fine for me with high CPU usage, 50Mbps is choppy like hell.
I have "dc:ff-h264" in the CodecInfo which from what I read means it's software decoding. In that case I am stunned how well it works, I thought it was surely hardware decoding since it had only slight problems.
If this is really software decoding only then the CPU in Fire TV is very powerful. My old PC wouldn't be able to handle that.
I will update this post when I find how to force hardware acceleration to work.

That is software, you need to enable hardware in the system config. It should be on by default, but I am not certain. Check under video->acceleration and be sure to enable expert settings. Decoding Method should be set to hardware. And you can play with Allow libstagefright, MediaCodec, or both.
Edit: With both enabled I just tried JellyFish @ 50mbit and it played flawlessly. I'm on Kodi and Amazon Firmware 51.1.4.0
Thanks for the JellyFish test. It sounds awesome that it works even at 50MBit.
I have hardware acceleration turned on (I tried all options there) but for some reason it doesn't work - maybe I'll switch to SPMC if I don't find a way to force it - right now I use Kodi nightlies.
PS. Restarting the device helped (at least for now). I will observe how it will behave in the future. (for now both amc-h264 and stf-h264 work) I had the device running for a few weeks before that, maybe something got locked.

I can confirm the same. Not rooted AFTV, Kodi official release, both hardware options enabled and latest firmware (in Germany)
Thanks. After restarting the device it works for me too. Turns out it might be good to restart it from time to time. Stupid me for not trying it right away.
hi.
Maybe it's me but I could have sworn on the s20 Ultra you could record with the above setting without a time limit.
Today I went to use my phone and it had a 22 minute time limit.
Is this normal or am I missing a setting somewhere as 30fps at the same res has no recording time limits.
I think I also updated my OS yesterday. Maybe that had something to do with it?
Deliting battery app data allow YT and other app to work on 120hz but everyday I need to do it again because YT go back to 60hz.
Any workaround?
Thanks

Reboot
Yea, I did that but except that.Did someone find permanent solution!?
Tried this and I think browsing in brave became for fluid. Dont know how long will it last. Scared at first when I delete the data in battery and performance because reboot takes longer than usual. And it reboot in miui logo two times.
Global OP11, the latest OOS. YouTube video lagging during playback every few seconds – a little freeze then continues playing. Not happening to all videos but to many of them. Clearing the all data helps just temporarily, lags come back very soon.
Any idea how to fix this? It's so annoying.
Yep, that depends on OnePlus that block the FPS to 60 on some apps and even the clock speed
found out that lagging happens only when connected to wifi. so not sure if it's related to the 60 fps limit.
Bad wifi or bad internet

because I know my wifi connection is fast and stable. all my other phones, tablets and laptops don't have this issue.

Maybe the op11 have probs with your wifi 2.4ghz or 5ghz wifi ?
Youtube has geo bandwidth allocation and can cut down streaming speeds almost to 56k modem performance.
Either they are testing or intentionally slowing down downstream to users in your area.
No issues with YT app for me, I was traveling entire week by car with YouTube streaming constantly videos without any issues.
I have this exact issue for a while. Only on wifi, I'm using revanced, and my wifi is very stable at 600 up and down. When toggling off wifi, YouTube says "back online" it is more of just a stutter every few seconds, but it's noticable and again only on wifi.

I had the same video lag issue in my revanced YouTube. It got fixed after I enabled Spoof App Signature.
Bug on youtube (looks familar after 8 min yt crashes on my j120f)
I can confirm this happens on my end as well. Super odd. Also noticed the app itself kinda goes into a very brief unresponsive state. I'll try scrolling through comments and it'll delay a second or so every so often. Other times, works totally fine. Using WiFi 100 percent of the time, so if it is anything with WiFi, not sure why it would only be periodic and not constant? I use the same wifi and it's been reliable on times I've noticed this behavior.
I may install a logcat/dmesg app and see if I can pinpoint where the issue is occurring. Anyone happen to grab a log I could take a peek at since it only happens on a rare basis on mine.
The condition the lag will happen on my side.
Is when playing a video/livestream in minimized mode (the video still playing at the bottom)
Then when scrolling through video catalogue it will lag.
Also when scrolling through comments it will lag.
Ok, I just tried what you all experience and everything is working fine. tested on my 5Ghz wifi at home, 5 and 2.4Ghz wifi in the office, different hours, multiple testing sessions.
No lags besides atrocious 60fps scrolling.
Playing video and then scrolling through comments, everything works fine, another batch of comments is loaded in very fast.
Minimised video and browsing through Home tab, Subscriptions or Library - everything is working fine on wifi.
I have Asus RT-68U at home and typical professional IT hardware switches, access points for networking at the office.
Since day one and 60fps there was no issue with YT app for me and i use it daily for videos, long review or video podcasts during my frequent traveling.

My issue is when simply watching videos in Fullscreen and on wifi, but only every now and then. Either way, if you use revanced and use microg version, the app is not 60fps limited. (You may not want to for battery, but it's worth it for me.)
I use stock YT app, don't need anything else. I have YT premium subscription.
No problems with fullscreen videos on wifi.
I experience this as well on my stock US variant
