[Q] Choppy Video Playback Until Second Time Playing? - EVO 4G Q&A, Help & Troubleshooting

Running stock 2.2 with Netarchy's 4.1.9 kernel.
Noticed that since 2.2 my recorded videos have been playing choppy (half the frame-rate). If I let the video play through and then start it again, it plays just fine. Even if I go back a second to a part that has been played, it plays fine.
Doubt it's an issue with the SD card because it played fine pre 2.2

Hoping someone might have an idea

My guess is, because of the new kernel, the SD card read speed isn't good enough for the bitrate of the video, and the video is being copied into the phone's RAM the first time through, and by the second time, it's in RAM, so it's nice and fast.

I think you're right, I did a wipe and flashed a fresh install + TI restore. Works perfectly fine. After flashing a different kernel it starts to screw up.

Video camera FC

I just noticed that when try recording 720p video on my SRF 1.1.0 Epic, it FCs at around 10 seconds. I seem to recall reading on here it could be an SD card issue, but before I go and reformat my card, I wanted to know if anyone had found an alternative solution to fix the problem.
Rarely use the video camera, so it's not the end of the world having this issue, but it'd still be nice to get it fixed for when I do need it.
Also, it seems to work on lower resolutions, just not 720p.
Almost like my SD card can't keep up with the data rate of 720p video.
EDIT: just occurred to me I didn't mean FC, it just says recording failed.

720p video lags on cyanogenmod 7

on stock desire, 720p playback on moboplayer or rockplayer, the same 720p videos were runnning smooth (only some rare very brief freeze at times) but on cyanogen using moboplayer, 720p; the video runs very very slowly and sound is totally out of sync.. what settings do i need to change to get playback as smooth as on stock rom??
edit: thought cm7 was supposed to be better than stock rom in terms of performance...
no one has this same problem?
i've had similar problem. let me say first that video recording worked great on unrooted device, then on rooted with stock rom, then on InsertCoin 2.0.1. rom, then back on stock rom (i went back with clockworkmod recovery), then again on Insercoin for a week or so...(don't ask, i did some experimenting )...
but then all of a sudden, after a full week on Insertcoin ROM, without me installing something new or fiddling around, out of the blue, video recording went loco. everything looked ok while recording but when playing video would pause every few seconds, then quickly catch on, then pause again, and so on...as if sd card couldn't catch up writing the video. but that couldn't be the case because everything worked fine before. i forgot to mention, both 720p and 800x480 recording didn't work...
i didn't try removing setcpu app and defragmenting sd card. instead i went back to unrooted stock rom and now everything works fine again. now i'm little tired to root and flash any custom rom over again. if anyone has the idea what went wrong please share...thx!

i will try defragmenting sd card. If it does not work, will switch back to stock rom. Got some other issues with cyanogenmod 7 also.... it is not as great as everyone keeps to say...
today recorded video started pausing again. i forgot to mention it earlier, but i bought new 8GB class 4 SD card and it didn't help. i don't think defragmenting will work (at least for me). it seems that this prob might be hardware related...
I had this problem on relextense hd, just figured it was the norm for the phone

i read a few threads on this issue and it seems to me that it's because of gingerbread which does not have the necessary codecs... let's just wait for official gingerbread and see if it works again...
i have tried cyanogen 7 (android 2.3) and miui (android 2.3).. in both roms 720p lags
thx for suggestions, guys. but i'm on stock froyo rom. i'll try removing some apps and see if it's related. after i flashed back stock rom it all worked fine, but now it pauses again. i removed poweramp and rockplayer but no luck. i really don't want to remove all downloaded apps all over again....any other suggestion?
720p works fine for me. Maybe hardware issue?
i have some update on the stuff. today i uninstalled all apps i've downloaded since buying the phone, including the updates to it's native gmail and facebook apps. after that, i restarted the phone and voila, video recording worked again, smooth and steady.
so i went to install all apps again, one by one, and after each one i tried video recording again. the result was that after some apps video was recorded with pauses, and after some it wasn't. so i uninstalled those apps again and tried video recording, but it didn't help. then i went to install them back again but not in the same order as the first time. again video was fine after installing some apps and not fine after the others. but, it didn't pause after installing some apps for the second time, the same apps which i have installed the first time when video was recorded with pauses. so it seems it's not app related after all.
but, after so much installing and uninstalling it became clear that video recording worked flawlessly after each phone reboot. at some point after rebooting the phone video begun to record with pauses again. after some more testing i can confirm that this occurs after installing new (any) apps. as long as i don't install anything, video will record normally. i cannot possibly imagine what can cause such behavior, but for now it seems to be the pattern. i hope it'll help some of you with the same problem. but nevertheless this shouldn't happen at all. i have sent a ticket to HTC support, maybe they'll come up with a more permanent solution.

720p video playback is smooth on your cm7? i have tried cm7 and miui (gingerbread) and 720p video is slow and out of sync with the audio
seems it's related with your sd card.. what class are you using? i think the more apps u have installed, the speed at which sd card is accessed is slower.... my 720p recording/playback is not smooth as well, i have like 60-70 apps installed (lol), that's probably why

[Q] DINC choppy or laggy video after CM7 flashed.

Hello guys,
I flashed CM7 onto my DINC, and of course I cleared cache, firmware, data and everything before actually doing it.
After it came up, I began installing you tube app and such.
When I played video on it, any video played looked weird like it backtracked each second, like whatever image it played, it played it again 1 second of it and then moved on.
Very weird issue if you ask me, so I thought it was the youtube app or something, but then when I shot a video then showed it to my friends, same thing happened. So it looks like any video played on my DINC after flashing CM7, seems to be playing very bad.
Any ideas?
Running a 2.15 radio?
Yes sir, I am running a 2.15 radio. Is that bad?
Nope, it's mandatory. Which kernel, governor, and clock speeds are you running?
Allright:
Kernel: 2.6.38.8 incredikernel
Governor and clock speed: haven't changed them since I flashed this and ROM together. I also installed incredicontrol.
Would you like to do me some video recording showing exactly the lagging problem?
I may just backup everything tonight and reflash, see if that solves the problem, though I highly doubt it due to the clean flash and just starting to have that problem.

A few problems with my Desire

Hello everyone. I have few problems, as far tried PA, CM7 and CM10.
1. flash videos
when using browser, I can't really use any flash player. I mean, I can see the player and the button, but when "play" is clicked there is a short blink when "play" switches to "pause" but then it comes back in 1 second and still it looks like nothing was clicked.
2. camera
when I turn on my camera, sometimes everything in preview looks like this:
i32.tinypic[dot]com/dd27fn.png
so, when I use it for a while it turns to normal but when camera restarted it comes back.
When I try to record videos, it is horribly lagging. Also, the recorded videos lag as well.
3. youtube
it is about youtube application - normally, videos play just fine. but when i tap the screen to see the video length bar it starts lagging and blinking.
4. unlock screen
so basically in normal situations the unlock screen shows up shortly after clicking the power button, as it should, but when I want to check the clock shortly after I turn the screen off (it means I click the power button twice within few seconds) it shows up after about 5 seconds or doesn't show at all
5. mSDHC
When putting things onto SD card, sometimes it says "can't find file" and it just stops. Doesn't happen when using adapter.
And sometimes the phone says "SD damaged", tried with 2 sd cards and don't know whether it's phone or card.
Please help, I'm total newbie in rooting.
You're trying new and "in progress" ROMs. If you want 100% stability, stick with gingerbread. Oxygen 2.3.2 is rock solid.
First 3 issues are present in ICS/JB ROM's only, if you want something stable stick to GB ROM's.
Sent from my HTC Desire using xda premium
These issues may be due to unstable ROMs. Use GB Roms like Oxygen or Miui and it should be fine.
Thanks! That helped.
The problem has been solved so you can close the thread.
I wrote about this problem on PA forum and nobody helped me, they didn't know what's wrong.
Now I have only problems with my SD card, but will test some other cards and eventually post a new thread soon.

[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?

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.
