I'll make it short and to the point.
When I play a YouTube stream at 720p over WiFi on the stock firmware the battery drain is about 1% per 3mins. But on just about any custom KitKat ROM out there the loss is much more heavy, it's about 1% per 1.5 mins.
The brightness was kept at 50% in all cases. I tried even lowering the brightness but it had little or no effect.
I am beginning to wonder if these are directly related to the changes Google made to Kikat's rendering engine for UI and everything else as part of their project Butter.
GSMArena for example noted in their battery tests for several phones after the kitkat updates from Jellybean the video play back time has suffered.
I have tested this issue extensively with multiple ROMs against the stock .96 and .211 firmwares
You guys know a reason for this? Is there a way get around this? I really like the various KitKat ROMs out there but YouTube battery drain is too much an issue now and everything else is just fine.
Previously YouTube app on android depended on Adobe flash right? Now how does it work? Is the whole YouTube app on android running on HTML5 backend?
Hope someone else has noticed this too.
i don't think so bro

:crying: Hoping someone has. It's easily noticeable when you play YouTube videos over WiFi with any of the custom Kitkat ROMs.
If there is a way to track something or someone wants me to put out some of the log dumps, do let me know what I need to do and I will try post them here.
Not only YouTube man its just when you play videos example: MX player you'll notice the difference
Sony ROMs are the best if the had the speed of cyanogen ROMs

Did another comparison with stored 720p MP4 video
Stock ROM .96 stock Movie player from Sony ---> 1% for every 4mins
KitKat ROM stock Movie player ---> 1% for every ~4.1 mins
More or less the same.
So the curious thing is WiFi radios are the same in both cases when I play YouTube streams at 720p and the stock Jellybean does better on the same version of the YoutTube app while KitKat ROMs, all of them so far, eat too much battery playing the same YouTube stream on the exact same WiFi Radio.
This is why I am thinking it's something to do with how KitKat itself is designed to work now with various apps. Maybe something inefficient is triggered in KitKat while playing YouTube.
Could be it be that Hardware Acceleration is broken in KitKat for YouTube?
Anyway to track the levels of acceleration?

couple of questions about streaming to the gio. which program works best and with which settings? i have real problems when streaming anything other than low res avi files. cant seem to get the transcoding options right on the pc end. also is there a player thats best for it? what causes the choppyness? is it the cpu more than the video hardware on the phone? i've tried stopping all running apps in the background and its still not smooth. any suggestions aside from manually converting every file? its gotten to where im almost ready to get another more powerful phone. i've tried several roms hoping for some sort of hardware acceleration but havent had much luck.

Which rom are you using, if you are on cm9 or 10 I understand that streaming won't be that good. but if you are on stock rom or something like Enhanced236 it's indeed weird. I got a few tips if that's the case. Try using MX Player, overclock your device when your watching a video (min:800 max:800), download the video instead of streaming it, trying to watch something in 1080p only will be rough on your phone, try converting the video to 320x480.

yeah i've been converting lately. seems easiest to just change resolution doesnt take long with handbrake. still would be nice if it was automatic plug and play. currently using enhanced rom. will try stock rom though just to see.
So what happened from any of the custom stock ROMs including the rooted stock ROM to this ROM?
I'm asking because when I first got this phone I didn't root or ROM it and it had hardware decoding for my full length mkv movies. And they played just fine in the native video player. No shipping or slide show and no out of sync audio. When I first rooted and keep a rooted stock ROM on it. Everything was still fine. I tired fre3 ROM and it was fine. Jellybomb was also fine. But they didn't have working tethering always crashed. So I moved to this ROM. And now I no longer have working hardware decoding for mkv.
Why is that? What is the difference between this custom ROM than a rooted stock ROM? Is there a way to add it back in so that it can be played natively?
Thanks in advance

Liquid smooth is AOSP and all the other roms you mentioned are Touchwiz (based off of stock).
Yes I understand that. However that really has no bearing on what I'm asking. I guess what I'm asking, if I can make it clearer. Is why was mkv removed from the native video player. The native play that comes with android not TW not SENSE but android. It has direct access to h/w decoding for all formats it supports.
http://developer.android.com/guide/appendix/media-formats.html
This way you don't need a third party player to play these formats. This way it can be played natively with the android player that comes with every version of android regardless of the OEM and their silly UI.
That's all I was asking. If a developer of Liquidsmooth could answer or let me know they're looking into it. That would be great.

If you want an answer from a developer, then you should ask in the developer thread for LiquidSmooth.
I'm sorry if this is not the right thread to post it(I've searched extensively in this thread but to no avail), but I have 2 main issues with the KitKat ROM for my GNex.
FIrst of all is the issue regarding locking your screen when playing music. When I'm playing music and locking the screen, the phone will suddenly stop the music suddenly and then resumes. This gets quite irritating but I don't know if this is normal KitKat behaviour.
Secondly is that 720p playback with MX is very laggy. In my experience with stock, I've seen better peformance out of the player, and I'm kinda weirded out by this.
I'm using the stock kernel, and what not. The only app that I use that effects many apps is Greenify(Oh, and I don't greenify the music app).
Even I did a clean flash the problem persists.

I know that MX player was having issues with early builds of CM11 but don't know the particulars for Playfulgod's rom. I would try and flash another CM11 based rom and see if you have those same issues, if not you can boil it down to that particular build.
Hey , since 2 to 3 days I'm having this problem with my galaxy grand that while watching a video its getting stuck its not hanging or anything it just stops for a second

Uninstall the anti-virus software, I think that is causing the problem ,
Also I think that it is a problem inside the rom,
I think it must be too much ram usage.
Are u using stock rom or custom rom

The best anti virus is common sense. Anti virus software will only slow down your system, be it your phone, your PC, your laptop, etc.
Please provide as many information as you can. What firmware are you using? What Android version? What video players did you try? It looks like a regular lag/stutter for me. Remember that Grand is not a fast phone, try not to play full HD videos with massive bitrate.

Uninstall the anti viruses dude. There's no need to install such thing on other systems than Windows XP.
Are the videos HD (720p/1080p) with high bitrate? I personally had lags and stutter while playing a 6 mbps H.264 1080p video on Vplayer, so this could be the issue.
Do you have any app running in the background while playing the video?
Do you use SW/software or HW/hardware decoder in the player setting? I personally had massive lag using software decoder on Vplayer.

I have been watching these series since long time but since sometime it started lagging. Its the same quality in all the videos
I trief both hardware and software decoders but it lags in both.
There are no apps running in the background.
But my ram isn't reducing from 500MB is that a factor.
I'm a user of grand 2.. strange I have the same exact problem as you.. I'm on kitkat stock.. I never had issues before while playing hd videos even on high ram usage.. gave a restart it didn't work .. I think factory reset will work, mah I'd loose my data.. mx player with sw decoder and hw+ decoder works fine,I guess ill stick to that for a while
i too have the same problem...what to do dont know......anyone knows abt the prob please let us know....
Hi,
I am having serious issues playing videos on the device. The stock players (photos and movies apps) won't play anything I get through whatsapp (mostly sent from iOS devices), many vids from YouTube, nor the sample videos which were pre-loaded on the phone (?!?).
I downloaded MxPayer and VLC, which mostly solved the problem, but I'm still having problems with the YouTube app. In case it helps, here is an example of a video I can't watch (my one-year old's favorite): http://youtu.be/VMl0GbiVEyA.
The phone is brand new, arrived 4 days ago. I'm running the latest firmware (Kit Kat, build 14.4.A.0.108), which the phone prompted me to install. It is not rooted and I hope to keep it that way, at least for a while.
Any ideas? Is anybody else experiencing this?
Thanks!

I use vlc as only videoplayer (deleted all others), vlc plas all videos for me. The video you mentioned I can't see here in Germany due to copyright issues.
Thanks, but what about YouTube? How do you force the YouTube app to use VLC as the default player?

i use firefox as browser and use youtube from there. I don't use the the you tube app.
Ah, ok. Well, if anybody has a solution, that would be great. I really like using the app, would be a shame to have to use the browser.
I'd do full wipe of the Phone and start over by flashing a ftf. Z1 Compact Resource Thread -|-Rooting-BL Unlocking-Firmware & More...
Thanks, but as I said, not rooted, and trying ypto avoid going down the road of endless tweaking and customization.
I downloaded a few alternative YouTube players, and they all work fine. I'll choose one and see how it goes. Want to know if I can go " average Joe stock" user this time around.

You don't need to be rooted to flash your Phone, the flashtool would be pointless otherwise. Install the flashtool, flash a ftf, done, it's as simple as that.
