Hello,

i have recently the following problem - youtube videos are not prebuffered as before so i cannot play the whole video. It happens randomly for some videos there is no problem but for other, there is such. Only the first 5-10 seconds are preloaded and when played, it stays like that, the grey slider that shows the prebuffering process does not move and it is loading and nothing happens. I do not have a second PC to test it. I have only one old laptop. From time to time i have noticed that the fan becomes very noisy. When i try with minitube application, most of the videos are played OK, with no delays and buffering problems. I already re-installed flash player. I even switched to the youtube's experimental html 5 palyer version - the problem did not get fixed. I cannot understand where the problem is, because it is happening randomly. FOr the same video - soemtimes it is working and sometimes not. Example videos:

1. http://youtu.be/RtvM1hxDA1s

2. http://youtu.be/UqXVgAmqBOs

I have this problem in both browsers - Google Chrome 16.0.912.75 and Firefox 4. Sometimes the video gets restarted from the beginnig when it cannot be played fully. I have tried also on my phone, running Android, there there is no problem with the youtube application. I am able to watch live TV streams and to listen to live radio streams.

Has anyone had a similar problem?

Hello

Could be a video card acceleration configuration .... That's enable or disable?

But is more easy to be problems with the hosting site, with any of the dozen or more hops that the data take on the way to your internet service provide.

I saw commentaries to disable the acceleration card, but isn't cool

Cheers

I think that disabling hardware acceleration is generally suggested to cure things like the recent "I see blue people" problem, but I may be wrong.
I've seen Youtube videos not buffer properly too, as have people I know. Seems to me like it's Youtube serving them slowly. They usually work for me in the end but only when my bandwidth keeps up with the video or I re-open the page when sometimes the buffer more.
I would suggest using one of the Youtube downloaders for problematic videos. They're not ideal in some situations but they get the job done and let you watch the video without worrying about the network.

I use one of the youtube downloaders and play back videos using vlc or mplayer on my FreeBSD box which is an older unit. This solution works quite well.

Is that a trusted link -- youtu.be? That could be your problem.

I've been using down load helper from firefox add ons i keep it turned off until I want to use it. I works great and has turns of features I need to grow into for music too. We need a more open source alternative to youtube.

I find those dodgy looking too, but it's legitimate: http://en.wikipedia.org/wiki/.be#Domain_hacks

I tried with a smartphone using WLAN connection at home and it had no problems with playing several videos. It seems that the connection is not the problem. Could it be because of the video card? Or probably some updates that could influence that? I am using Google Chrome 16 and Firefox 4. I have version 11,2,202,236 of Adobe Flash Player installed.

Unless it is only specific videos and it's repeatable, then it's not likely a video card problem.
Having said that:
Does turning off hardware acceleration for Flash work?
Are the ones you're having problems with higher resolution?
Does it happen after watching a few videos, or can it happen straight away?
I'm not saying there definitely isn't a problem with your setup but I've known the same buffering problem happen on the same video for different OSs in different countries simultaneously -- pointing at it being YouTube's problem.

How do you "turn off hardware acceleration" for Flash on Linux? Isn't it off by default, unless you force it on with an mms.cfg file?

Anyway, I struggled with this problem on Crunchroll (and Windows). The main causes were:

a) I was using Google DNS, which confused Crunchyroll's CDN and caused it to send me video servers in Malaysia. Switching back to my ISP's DNS servers helped a lot,

b) I was connected to my router via wifi, which did not have the reliability needed to actually watch 1080p streams on Crunchyroll. Switching to ethernet cables helped with this.

c) My 2Ghz Core 2 Quad, unbelievably, seemed to be too slow for some of the flashier scenes. Upgrading it to a 3Ghz I3 (again, unbelievably) helped with that. That should tell you what utter crap Flash is.

There's a tick box when you right click and bring up options. No idea what the default is, but if you turned it on and you're having a problem then turn it off and it works that would point to drivers. Heck, if it's off then you could try turning it on.
I'm not convinced this is anything on the client side at all but it's worth trying these things.

Hello,

i have never played with Flash's hardware acceleration. I just figured out today that it was turned on for me.

I do not use Google's DNS, but the ones from my ISP. My laptop is connected to my router via cable. The problem started 7-10 days ago. I had absolutely no problems before. I do not remember was it some update or what that caused this malfunction. I have Core 2 Duo processor but for now i cannot afford to upgrade it.

I tried to turn the hardware acceleration off but it is the same sh*t.

The problem is actually like that - the video starts to play for first 5 seconds and then it starts to buffer. It could buffer for minutes but actually the grey scroll does not move. In some minutes it could start to play for some time and then stops again.

I was testing with 2 videos:
http://youtu.be/SRAOG-BpNOw - a lyric video - first 5 seconds and then pause

http://youtu.be/0NKUpo_xKyQ - 30 seconds and then pause and in the mean time the laptop's fan accelerated a lot during those 30 seconds.

was going to say you can use HTML5 but I think you might be already on Firefox4.

Guys,

i have not done anything, but i start to notice that things has become a little bit better. I slightly have problems with the prebuffering now. It seems to have gone as it was before. I will continue to monitor how it further goes and let you know. Now i seem to be able to watch videos in a regular way.
