Pausing HD videos puts Audio and Video out of sync? - Galaxy S I9000 General

Heya. I've recently copied a lot of 720p .mkv files on my phone to watch while commuting.
It worked flawlessly with the first file I copied. I was able to pause and play it without any harm done.
When I finished watching the video, I deleted it off my microsd and earlier today I copied two more (at the same time) to my phone.
I found that whenever I paused the video, the sound and video became out of sync when I started playing again. There was a 3-4 second delay between what happened on the screen until the sound came. It's very annoying.
Has anyone else had similar problems? I'm using a Sandisk Mobile Ultra (16gb) card, it's class 2 but considering video playback is flawless if I don't pause it, I don't think the class will matter? My transfer rate with the card is about 7mb/s.
I also noticed that when I paused videos there was a split second delay between when the video paused and when the audio was paused. Maybe this contributes to the syncing problems when I play again?

Did this only happen with the last video you copied? Have you tried it with the one you didn't have trouble watching intially? I haven't found any such problems, but perhaps a reboot of the phone might fix it for you unless the problem is with the file itself.

This has happened to both the second and third file to be copied onto the memory card. And yes, I tried to reboot the phone. I also killed all the running apps with advanced task killer.

Well it could be that the phone doesn't like the codec of the files? Try RockPlayer and see if that gives you the same problem. Also try the original file that you didn't have a problem with perhaps?

New Video Problem

Alright here's the deal, I got my HD2 when T-Mo had their sale on the 19th, so I'm pretty new. I've searched the forums, and I found several threads on the audio/video sync issue, but they don't help me too much with the problem I have. I used Red Kawa video conversion software to convert my MKV files to MP4, and while most people were saying the HD2 is the cause of the delay, I will note here that my videos were out of sync before I ever transferred them to the phone, so I had to delay them from the get-go. That's not my problem though. Now that I have about 10 videos in the correct format for the phone (800x480, video 1024kbps, audio 192kbps, -200ms delay) once I actually place them on the storage card and play them, they look fantastic until 7 minutes into any movie I play and the phone freaks out. Regardless of whether I'm in Album or WMP, and TCPMP won't play them hardly at all. I also can't use the slider to select any part of any video or the same thing happens, complete freakout. It's the weirdest thing, and there are videos I put on the phone without the delay that worked fine 2 days ago, but these mess up like clockwork EXACTLY 7 minutes in! Any advice here would be much appreciated. I haven't used Windows Mobile since the 2003 version, so I'm new to a lot of it.
Just wanted to add that the videos play perfectly on my computer, and I can use the slider on here to change spots...
Whoops! I thought I had both Anamorphic and Widescreen profiles set up the same, turns out one was on the Baseline Profile and another was on the Main Profile. As a result Anamorphic (Main) movies play fine, they're still not really slideable, but they don't jack up at 7 minutes.

[Q] I9000 cannot play mp3 smoothly unless completely disable data network

I9000 cannot play mp3 smoothly unless completely disable data network.
Does any feel that the I9000 cannot play mp3 smoothly?
It always has some pause (0.3~0.5 seconds) during play any mp3 even in 128 kbps CBR [around pause for 5-8 times in each 5 mins mp3]
I just found that, if GPRS/EDGE/3G(HSDPA) is turned on, this problem will be happened. That is no problem with Wifi.
One more, if you try to keep the Data connection e.g. downloading a large file via GPRS, that will be no problem as well.
I do thank that when any app/module want to access the Internet and "start" the data connection, this "start" will trigger the mp3 un-smooth problem.
Anyone playing with issue as well?
Am I alone?
Have no issues of the sort, FLAC and mp3s play flawlessly.
Stock rom, JF3, non-rooted, no ATK or taskkillers in general.
maybe your phone is sync-ing too much stuff in the background
try turning off Facebook, email sync, tweet sync, etc, etc
I played a lot of Flacs with mine and it did have tiny pauses now and then as you described. Sounded as if the cpu was busy (synching or doing something else) or maybe there was heavy I/O activity and we know the SGS isn't brilliant at that.... in any case, decoding lagged sometimes.
Still, the pauses were fractions of a second and fairly rare (perhaps once every 15 minutes or so). Audible, but tolerable given the overall good audio quality of the gadget.
I am new from i9000 and I have the similar issue.
Although I had disable all the network traffic (APN/WIFI) and I was only running the MP3 player, the song still played with some stop.
I had try lots of MP3 player apps, such as Astro player, TuneWiki, Kiss Music Player, MixZing, etc. No one can play song smoothly on my device.
Can anyone tell me how to improve it?
glitches if flac
Just another confirmation I've noticed the same issue with flacs on JG4. I get a glitch every 5 to 10 minutes. I've not listened to many mp3s so I don't know if it happens with them as well.
Yeah mines the same. Gets worse when the signal is dropping, almost useless when im on the train.
Contemplating about using my trusty itouch just to listen to music. Btw its unrooted with the one click lag fix

Its the firmware, I have tried many since the phone came out and about 50% of the firmwares have this problem, songs fine but every few mins there is a tiny pause/skip or what you want to call it, I have just moved to jpc but not tried any music yet to see if this one has same issue, but seeing as most are leaked there is always going to be an issue with something, guess the time we can really complain is when the real 2.2 comes out, if that has problems then its fair to have a go at Samsung.
I've upgraded to JM2 now, and I still don't have any troubles with my music player. mp3s and FLAC, no skipping or anything. Just smooth.
Oh and btw, I play my music from the internal SD.
Same problem here on JM6 (with and without ryanZa lagfix) with mp3's and videos.
No matter if internal or external sd card. Glitches occur approx. every 3- 5 minutes.
I'm not sure but i think there were no problems with stock JF3 firmware.
Edit:
Flashed back to stock JF3.
Music is playing flawlessly.
solved... kind of
Found what was responsible for my problems with music and video playback.
D-Clock Widget by mt. On every minute change playback stutters.
So check your widgets and apps running (in the background)
greets,
nerv
Eww leak on a clock ...
hey there. Please check if you are scrobbling music on your phone through last.fm!
I had this problem too. I used many scrobblers same problem. I disabled it now
another thing to check
many music player software will automatically download lyrics and arbum arts to the phone, those can also slow down and make it sluggish
Solution is not existed under 2.1, but don't worry

I'd like to change to I9000 and now I have HTC Desire, and I know what about you say. Under Eclair the garbage collection is terrible. Every garbage collection takes 0.1-3 secs, and then everything frezze.
Don't worry the Froyo will cure this - have to wait only 2-3 wks.

MP3's Freeze my Tab

I have a stock T-Mobile Tab. I have a 16gb memory card installed in it, with quite a bit of music on the card. Whenever I play an mp3, it works fine....for the first song. It seems that about halfway through the second or third song, my tab always freezes. It doesn't seem to matter if the music file is on the sd card or my 16gb's of internal storage, it still freezes. I even placed an mp3 that plays through fine the first time on repeat to make sure it wasn't just bad files. The mp3 that worked on first play freezes upon being repeated.
Is this just me with this problem? Any ideas what it could be?
My tab doesn't freeze, but it does stutter/skip after a few songs have been played. I think there are two possible solutions. First, try a different music player from the market. I think skipping/stuttering is a known issue of the stock player. Also, maybe the quality of the SD card could be the problem. I bought the cheapest card. So use someone elses card to test that out.
Let us know how it works out.
My uk tab o2 has this issue to every time I start a track in music app built in the phone it shuts down. Also happens with stock email client.then opens on second try.
This is my second tab with o2 and the last had same issues.....

Check the notification area if the media scanning is running, it is the sd card icon. If you have thousands of mp3 as in my case, scanning uses up the cpu slowing down the tab considerably.
If you want to cancel the scanning, you need to root your device. You can download z4root to safely do it. Then download Rescan Media Root. This program enables you to disable scan.
Note though you need to really run the media scanning for newly added media files so those can be accessed by the stock media player. You do this at night before sleeping. Mine takes about five hours to complete.

MP4 Corrupted when transferring

Hi,
I've just tried to transfer my photos/videos from my phone but the video files wont transfer as they are corrupted, I've had partial success by transferring them through wifi to dropbox but when playing the files they have parts missing and stutter. I've tried transferring them through windows 10 and on a mac with similar results.
Strange thing is the videos play fine on the device??
The phone has been encrypted and the videos are in 4k - the memory card was bought from argos so I'm guessing its not a fake, the model was "SanDisk Ultra 80MBs MicroSD Memory Card - 128GB"
Wonder if anyone has any suggestions what could be causing this or how to fix it.
Just an update, I managed to transfer the files to Google drive but it seems to have converted them to HD. Also the files have a few popping sounds on them which could be where the files are corrupted.
I've ordered a better memory card to see if this stops the problem.
Can anyone think how to get the files from the phone as I'd like them even if they have slight sound errora on them - they are family videos.

Found this thread Googling - it's almost an entire year old but thought I'd post anyway
If you can still play the video on your phone all the way through (I just skipped through sections), open the video in the stock editor and export it.
It'll drop the quality a touch, but it's nothing you'll even notice, which will save you some space too.

Playback halts abruptly - all video apps

Not posted in a while as I've been largely enjoying the Mojo trouble free. However yesterday I was watching one of my video files using SPMC and it just stopped, sending me back to the video selection screen in SPMC. I'm using a 2Tb WD USB hard drive, on my Mojo is CM 12.1, and SPMC is my usual choice to play files back.
This was an MP4, 1080p at 2.7Gb, and this was a 3 hour movie, which ceased playback at the 2 hour 15 minute mark. I attempted to resume to playback, but it seemed to try and then immediately dumped me back again.
My first thought was it must be a corrupt file, so I tried it on my PC but there were no issues. I go back to the Mojo to try restarting the film from the beginning again, skipping ahead to the troublesome part, but it stopped again at exactly the same moment.
I then tried VLC, and to my surprise I found this was exactly the same. Playback ceased at the same point exactly.
So now I'm worried it's the drive, so I decide to plug it into my Raspberry Pi which is running the latest OSMC, and to my surprise it's fine. Playback is trouble free. Plugging the drive into my PC to play the file reveals it plays fine. It has to be the Mojo, but it must be a global setting or something. I've tried clearing the app cache, but it's made no difference. To be honest I don't really know where to look next. Can anyone help? Thanks all.
tl;dr: File plays fine on PC and Raspberry Pi, stops abruptly on Mojo using SPMC or VLC. Must be a setting somewhere to fix. Help!
Well now here's an interesting discovery to make after several months of ownership! I always was slow on the uptake...
It seems on further inspection that the Mojo/CM 12.1 doesn't like any of my "large" files above 2.5Gb. I have tried some others around that size and larger, and they are all the same. The are slow to use (skipping forward etc.), and then just give up so far into playback. My drive is formatted NTFS, so I don't think that's the issue.
I'm really hoping there's something I can do to fix this.
Aaaand on even further inspection, file size has nothing to do with it. There's a number of files that just won't play very nicely, big or small. They lag when skipping through, and then cease so far into playback.
I'd read that Android wasn't so great with video codecs generally, and this must be what they mean. Can't believe I didn't notice it before.
I had the same issue with videos over 2GB. It is an issue with NTFS. The same files played fine on a FAT32 drive. I have since gone to using a NTFS NAS instead. Works flawlessly with Kodi.
Thanks for replying. I've ended up simply remuxing and replacing those problematic files, which seems to have resolved the issue. It's a pity, but I am finding the Mojo a very fussy and particular system indeed. What a shame, as it is so capable at hardware level.
Tried playing the file with Kodi?
That's usually my fix to those type of situations.

Sorry for late reply. Yes all the video apps show the same result, which means it must be the system. I've read up a little on this and have discovered other folks with similar issues when using Android for video playback. I'm fine now anyway - like I say, I remuxed these troublesome files and made them smaller but no less qualitative. Some of them were quite big for DVD rips (around 3-4Gb) and did not need to be so. Thank god for Handbrake! It worked out well in the end as my drive was beginning to be pressed for space with so many of these, and I've managed to free up 70Gb just by being a little bit more conservative.
