Streaming Video/Audio Sync Issue

I have a stock HTC Wildfire S that got the ota update to 2.35 er so. Before and after the update I am experiencing Streaming Video/Audio Sync Issues when trying to play video through my browser and the Netflix app. The audio rolls along with no hinderance or interference while the video stops, jumps, glithches or just plays but way out of sync with the audio. I have tryed several different websites to no avail. The craziest thing is, through the Youtube app, all videos play crisp and with no flaws. This is all being done over WiFi and has been tested on several different WiFi connections. On a side note, formated videos that are on my SD card also have no issues. I have the version of flash player for my version of android installed and 30-40mb of open internal storage.
Any idea would help, ty.

Same here. I wonder if overclocking is needed to get Netflix to play decently over WiFi.

Same here, I 'm even trying to get Skype to work. My wives LG Optimus Elite can stream Skype and Netflix video just fine even over a good 3G signal.
Yet on the Wildfire just trying to do audio with Skype wont even work on WiFi.
I am regretting this phone more and more.

Video playback stutters over wireless only

Hi folks,
I'm stumped on this one, wondering if anyone has seen similar issues or has any ideas.
Basically, many videos will playback with extreme stutter over wireless. I've tried every video player I can think of and I've also tried alternate sources (NAS vs desktop share). The reason I know this is only a wireless problem is I have no issues with identical clips once I copy them to a USB and play them using an OTG cable.
I thought at first it was a question of bandwidth, but I'm on wireless N and the problem persists on even a 640x480 .avi file @ 1250kbps, which wireless N should be able to handle.
Any thoughts, ideas, or suggestions? Thanks in advance!
TLDR: Many video clips stutter only when played from a wireless source.

Bump! Anyone have any ideas?

I'm experiencing this problem to when streaming videos from the interwebz, opening them in MXPlayer.
Does anyone have a clue what this might be caused by?

Bump numero dos!

weird, i can't play youtube videos, stutters, not sure if if its the device cuz i have fast wifi connection speed, 150Mbps connection it says on my 5ghz N router
im thinking its device wifi hardware issue and not my actual home wifi network

Bump again. Find it hard to imagine nobody else is having this problem.

The stuttering is due to Google's poor implementation of video playback in the new youtube app. Uninstall all updates and use the stock youtube app for a better playback experience sans stutter.

I don't have problems with Youtube though. Let me reiterate:
Using the same exact videos and apps:
Play a video saved to my NAS or a Windows share via wireless - playback that stutters
Play a video saved to a USB flash drive using USB OTG - playback is fine
Again, this happens even with a 1250kbps video over wireless-N, so I don't believe throughput is an issue. I get 35mbps up 21mbps down on speedtest.net over my Nexus 7's wireless.

Just a suggestion, but try your video on some other network to isolate to a Nexus problem or something else.

Thanks, this is a good idea. I'll try a couple WAP networks at work tomorrow and report back.

I tried today using two different WAPs and the problem still persists. Any other ideas?

The only thing I can think of is to try a system reset. Be careful to back up your music/pictures etc.

OK, new development on this. Not sure why I didn't think of trying this before, but I did some testing with my 2012 Nexus 7. Has the exact same problem as my 2013 Nexus 7.
So at this point I'd have to think this is Android related and not hardware or environment related. Some sort of issue with passing data between the wireless hardware and the rest of the OS.
Thoughts?

Bump!

Can you provide a little more information please? When you say you are playing it via network using the MX Player, are you supplying MX a stream url? or you simply browse to the LAN share via a file explorer and try to play the video directly?
Did you try changing the decoders in MX Player? HW/HW+/SW? HW+ works perfectly for me on Nexus 7 2013.

720p and 1080p worked just fine over network with my Nexus 7 (TP-Link 1043ND so nothing special, same old 2.4GHz N network) ..

I'm browsing to the LAN share using ES File Explorer and using that to play from the shares. Do you suggest something different?

I have had great success with DLNA media servers. I have PS3 Media Server (totally free) installed on my server pc. My Nexus 7 has BubbleUpnP which picks up PS3 media server flawlessly. BubbleUpNp is by far one of the best UpNp and DLNA client and server I have seen till date for android device (just my humble opinion). I have set MXPlayer as the default player in BubbleUpnP settings. I can browse and play anything, and its without a stutter.
Here are the details of my setup:
-- PS3 media server installed on
-- BubbleUpnP installed on Nexus 7
-- MX Player installed on Nexus 7
That's all it takes. I have taken this setup a step further for my own needs. I store movies on my Nexus 7 since I travel in the subway and I like to watch movies on the go. Now I have a Samsung Galaxy S3 and depending on where I am, I switch devices while watching movies. I would start a movie on one device and resume on the other, without actually having to store the video in both the devices. I tether a connection from my S3 and my Nexus 7 connects to the hotspot. I run BubbleUpnP on both Nexus and S3. The Nexus 7 acts as a server and sees the S3 as a client (renderer). I stream movies from my Nexus 7 to my S3. Tested with 720p movies and the result is flawless. No quality loss. Sometimes there is a momentary stutter but it goes away. It depends on how the video is ripped too.
You really don't need the S3 and N7 setup details. i just wanted to share it. Sorry for the long post. Hope it helps.

[Q] Chromecast & Nexus 7 Casting Problems

So I'm having issues with my Nexus 7 casting to my TV. I can cast fine if I have my tablet on and active but once I turn off the screen and set it aside, whatever I'm casting will only go for a minute or so before cutting off. It seems as if my WiFi is turning off and telling Chromecast to stop playing. I have already made sure to "Keep WiFi On Always" and also disabled "WiFi Optimization." The odd thing is that I do not have this issue with my HTC One.
I've tested this with Pandora, Songza, and Viki. I have also clean flashed stock OTA, CleanROM, and CM11. All no luck. The only solution I have found is to use an app called REGPON wifi KeepAlive. Does anyone else have a similar experience that can help me so that I'm not dependent on this app?

Nobody else owns an N7 with a Chromecast and has issues?

Hi,
I am also having the same issue with Viki. It is happening not just only on Nexus 7 but also on Nexus 5 too. I realized that other than Google apps the rest of the apps have this issue.

I'm having the exact same problem, whether using my Windows 8.1 PC or Nexus 7, but does NOT occur with HBO GO, but does with Pandora, Songa. Haven't figured out the solution yet.

Under WiFi advanced settings, check the keep WiFi on during sleep setting is set to always.

[Q] Online streaming issue

So... I'm trying to watch "How I Met Your Mother" on my tablet, but when i'm streaming it online, it stops and when I click play again chrome freezes and crashes. The online streaming works perfectly on my Galaxy S4, but not on my tablet. Anyone know a fix for this? It is really annoying..

I use dolphin browser with jetpack built in that supports flash. I have the most recent flash player installed. I played the latest full episode to try and it played fine in HD. It must be chrome giving you a hard time.

That didn't seem to solve the problem... Same issue with Dolphin. I use chrome on my Galaxy S4 and it works fine..

[Q] XBMC / SPMC stutters with nearly every video

Hi,
I bought the AFTV in Germany and installing SPMC worked fine. I was using OpenELEC before, but running XBMC / SPMC on the FTV seems to be better as I don'T have to place the bis computer next to my TV.
The problem I have: Nearly every video stutters from time to time (somtimes, minutes in between, som stutter all the way), althoug the network is fast (connected via Ethernet to a Syno DS214+ - single user so no other access).
Most videos I tested were MPEG2-TS (named .ts) or H-264 (also named .ts). But I also had an AVI that had this problem.
Any hints what to change to get this solved?
THX,
Matthias

You could try this: http://forum.xda-developers.com/fire-tv/help/xbmc-video-stuttering-t2852227. Also search here for other threads.

I already tried the different combinations of HW-acceleration (libstagefright and mediacodec) but it did not help.
I also searched for other threads and did not find a matching one ...
Greetz,
Matthias

I believe I have a similar (or the same) problem... It seemed to work fine for a few months but lately stuttering started to occur on a daily basis

Mine was doing that too, fixed after a reboot, not sure what it was.

Hmpf! Yes, well, in Germany, there is a saying for that: Sometimes, you don't see the wood because of all the trees.
I restarted (first thing I tell everybody who has IT problems) and, surprise, surprise: problem's gone.
Thanks a lot!

I had stutters using WiFi, but since I cabled my connection I can run 1080 vids from my NAS and .ts files from my dreambox flawlessly. Have you tried a different port on your router?

I did not use WiFi-connection but cable from the beginning.
After a restart, it worked yesterday.

Restart help a bit, yes, but this is a sloppy and a temporary fix... Maybe a nice Task Manager app could help clear some junk?

This seems to me to be clearly buffer bloat, certain routers and switches have an issue with the router equivalent of a memory leak. I reboot my router every day, and never have an issue. There are usually updates available, or if your router is the right type, alternate firmware that can solve it permanently. I prefer the once a day reboot.
