[Q] Playing video from micro sd or internal storage

Would it make any difference in battery life if video is played from Micro SD versus the internal storage? I am flying overseas and on a ten hour flight any extra battery life matters.
Thank you

With computers I always stick by the rule, any accessory drains power even if your not using it. That said I don't think that battery life difference would be noticed.
Dial down your screen brightness.
Turn off wifi, sync, BT.
Kill all Widgets and active desktop.
Kill all non essential apps.
I actually have a backup that is only for watching movies and listening to music on long trips. I used system app uninstaller to take out most everything I wouldnt need to watch movies. Mail, maps, voice. Basically I Yanked out all the apps and system apps that eat up processing time and ram space but never get used watching movies.
Tuned launcher pro down to 1 homescreen and backed it up. Then reloaded my previous backup. Now I have a portible movie player I can load up any time and get excellent life out of. I have watched movies with headphones for at least 10 hours with this setup but I'm sure it was more

Anyone else experiencing insane amounts of data usage?

I mean I rarely use the phone, much less 100+ Mb at a time, but looking at my usage log im at 4.75gb!!!!
HOW, I never used to go above 2.5gb on my G2. The only thing that may be causing the high usage could be the new google music app. I uninstalled it to see if its the culprit, and if it is then its going to suck because i really liked and even started depending on that app.
Here are a few screenshots of my t-mobile logs.
Please someone shed some light on this!!!

So reference that date and time and check to see when that Google music app was installed. If you are streaming, you will rack up the GeeBees.

Theres no way I would stream 300+ mb of music...i used to listen to online radio and not even pandora will use so much data in such a short amount of time.
It would be great if someone else who has the google app can chime in

If this is the result of using the Google Music service, then I'm glad that I decided not to use it and uninstalled it from my phone. I was really worried about how this would affect data usage, especially considering the data "cap" that T-Mobile has in place.

If it is the Google music app, then each song is being streamed at like 20mb or something which is ridiculous.
Ugh and I REALLY liked it, I had 300 songs up there already and enjoying the cloud service.
Is there another app that is similar? Anyone know?
EDIT: I have uninstalled it and will report back at the end of the day to see if data usage has returned to normal levels, if it has then my only conclusion is that it was the Google music service.

Amazon cloud service for music is similar I believe

yes my usage had doubled and I do not use any cloud based services. I have gone from 1gb of data usage a month up to over 2gb

google music is the problem yesterday I did a test
checked data usage was at around 250 mb
streamed music for 2 hours
checked data usage it was over 900 mb
WTF 650 mb for 2 hours of streaming
it dont even make sense your better off just making available offline if you wat to listen to music

So, was my hypothesis correct that GMusic was the culprit?

So, as a sanity check, I took OP's first block of usage as a test:
~130MB usage in one hour
= 1.04Gb
/ 3,600 seconds in an hour
= 289Kbps
I'm guessing that the bitrate for GMusic is dependent on the song, but has an upper threshold somewhere to ensure quality (i.e. GMusic will compress 360Kbps to sub-300 to ensure stream quality).
Seems to me that 289Kbps is a bit high, but within reasonable bounds for higher-quality streaming. Did I do the math right?

You may be right, if I actually streamed music for the entire hour, which I don't believe I did... I would maybe listen to about 4 or 5 songs max, I mean just look at what a previous poster said before me...he used 600mb in 2 hours of constant streaming.. Which comes out to 300mb/h...do the math there and see what the bitrate comes out to.
Either way, after uninstalling google music my data usage has returned to normal levels. I will post a screen shot when I get on a computer.
Something fishy is going on with the way google music streams music

Based on what I've gleaned from Google searches, here's what I calculated:
First some hard numbers --
• 1 Mb = 1,000 Kb = 1,000,000 bits
• 1 MBps = 8 Mbps
• Google Music Streams at a maximum of 320 Kbps
• 60 minutes = 3600 seconds
So if you stream Google Music at its maximum bitrate nonstop for a full hour this is how it works out --
320 Kbps × 3600 = 1,152,000 Kb/hr
1,152,000 Kb/hr ÷ 1,000 = 1,152 Mb/hr
1,152 Mb/hr ÷ 8 = 144 MB/hr
So the most the music streaming itself could use on the download side of things is 144 MB/hr. Perhaps the app is downloading/uploading other data as well tho as part of the streaming process? I'm not sure.
I have my Google Music app to stream over wifi only.

It's a little lower at about 140MB/hr since it's 1024K, not 1000K.

There are 1000Kb (kilobits) in a Mb (megabit).

1024 KB (kilobytes) in a MB (megabyte).
My math is sound.

Somehow I had it in my head we were storing data. Your calcs should be correct then.

Lol yea I hate calculating megabits and megabytes, etc. I always get confused at some point.

To the OP, can you check in your settings and see if caching is enabled? If it is, your music is being downloaded first before playing. To truly make it stream, you need to disable it I believe. This might be another reason for a rise in data usage?

[Q] youtube app not preloading all of watch later videos

I've been googling for an answer and haven't found a definite. I've been using the youtube preload feature to preload videos while at home so that I can watch them later during down time at work without using up all my data. Lately though it seems like it will only preload a couple videos. I plug in my phone an am connected to wifi and I see the arrow appear on a couple videos in my watch later list but not all of them. Does anyone know what could be causing this? is there some sort of limit for preloading or maybe a bug in the app? I tried clearing both youtube and media storage data cache with no change.

update: I went into advanced settings in youtube app and uncheck the "HD video over wifi" and went back into watch later folder and now most of my videos have the preload arrow on them... so, could it have to do with a file size limit? I would really prefer to have them in high quality, but I also don't want to use up all my data to do so... i hope a file size limit is not the case or that there is a work around for it.

Same here
Hey, I have the same problem as my phone only preloads one or two (max) videos on my youtube app and I've actually unchecked the HD option already.
My videos are usually 1hr long, so they should probably be what, 200 / 300 mb each? (depending if they are 360 / 480 resolution)
Does anyone know if there is a limit imposed by YouTube or if this is "self-regulated" depending the available amount of free space in the device?

I have noticed this also. I don't want to burn my data at work and the preload only grabs a few videos. Some of mine are only 10 minutes but still not downloaded.

I tried this solution and the mobile Youtube app did preload more than it had before. Might give it a try http://lifehacker.com/preload-entire-youtube-videos-by-disabling-dash-playbac-1186454034

Same problem here. Preloading works sometimes, regardless of size or HD. Tested with cm 10.2 on encore and stock 4.3 on nexus7.
I would really like to know why and when are some videos downloaded.
Is there a way to capture YouTube debug or trace logs?
Any help appreciated...

Yeah, I'm wondering the same thing. Been looking online for a few days. I can't figure out a rhyme or reason as to why some videos preload (green arrow), some have a white arrow, and some have no arrows. I've attempted deleted and adding them again to the list w/o success.
additional note for some, if they haven't noticed...the setttings section mentions "wifi and charging" required, not sure if this is a factor for some, doesn't seem to be it for me
not sure where earlier post has the 'hd setting' to uncheck. was this an earlier version of the YT app?
still troubleshooting....hmmmm.

I do not know but the answer but my educated guess is that youtube only Preloaded some videos, as it has some constraints on cAche size. It does optimize ratio of loaded videos vs available Cache, that's why the videos load it are random

[Q] Android youtube app

Is the youtube app on android extra horrible from the apple youtube app? I mean the android app has good video quality not like the apple youtube app were the screen gets out of synch or something, but I believe that the android youtube app has extream buffering or loading issues, since I often find myself were I have to pause the video and wait untill enough of the video has loaded, but most of the time it wont load past a certain point and keeps me hanging. I have heard that youtube has buffering issues universally from time to time but today I tried the same video I had problems with on my android device on my mothers new Ipad and there was no buffering problems what so ever, I will keep comparing and see what happens.
Anyway are there any rooted youtube apps or something that are more stable?

i think the android youtube app is actually better than the ios app, and many ios reviewers say the ios app has buffering problem. maybe your android has wifi issue
you could try this app to see if it's better though https://play.google.com/store/apps/...=W251bGwsMSwxLDEsImpwLmNvLmFzYml0LnB2c3RhciJd
it also support background playback

I think i have read about tf700 having wifi issues somewhere now that you mention it, what can I do about it? I watch youtube a lot so it is quite irritating at times.

If you have a buffering problem, you need to fine tunes your network and use browser2ram. Try these out:
1. Increase tcp.mem
2. Increase core.mem
3. Increase wifi buffer
4. Increase br2r buffer
Let us know how it goes.

wierd i cant find B2R on my device, can I download it seperatly somewhere?

Look in /system/etc/init.d.

I am sorry I dont know what you mean? is there a folder named system somewhere?

nvm i bought root explorer but i cannot find init.d, only init.goldfish...
Should I install the init.d installer app?
Also my device is only rooted no custom ROM.

So which version of B2R did you install then, which you can't find on your device?

no idea, I have done a comlete reset of the device ones when asus support changed the motherboard so it could be that I had the app ones but forgot that I dont have it anymore, anyway where can you download it seperatly?

pvstar works very good no lagg at all, i would prefer fixing so I can watch on the youtube app since I watch regularly but this is good emergancy solution.
Thx man!

SD Card for?

I'm just curious what you guys use your SD cards for? Really large game apps? Or do you move all of your apps onto your sd card after rooting?

Photos/videos. I have young kids, so I take a lot of them.

Music (lots) video's and pictures

Movies, music, documents, downloads, all my apks when needed.

Videos, photos, music etc.
BUt the most important for me are nandroid and TiBu backups.
Hopefully we get custom recoveries soon

Right now I have about 6.9 gb of photos, about 8 gb of music, and about 22.2 gb of movies. I'm putting the movies on there in preparation for a 2.5 hr flight plus hotel stay. I also have about 3gb of misc. files and titanium backups, and about 1gb of epubs.

Google play movies saved to sd....4k video...Dogg catcher video podcasts saved to sd...Google music...pictures of course.

Videos, pics, Roms[when we get some] and everything else.
Sent from the TermiNOTEr 4!

1) Nandroid backups
2) Videos and pictures I take of the kids.
With that said, I never use more than 10gb at any given time on my SD card. I've switched to networked movies and cloud music, video, and picture backups. I also always have a laptop with me. I can live without SD storage on my phones now without any effort on my part.
