YOU TUBE VIDEO STREAMING - OPERA 11.x - Part 2

Wednesday, August 17, 2011 11:46:40 PM

You Tube, video freezing, Streaming, Flash ...

Another setting in OPERA that might help with improving playback of
Flash Videos on You Tube is to change the settings for "Streaming"

Instead of Opera using the disk cache to load videos it should just "hand it off" to allow streaming with your connection's bandwidth. In fact its better if the disk cache isn't used at all.

I tried this on Opera 11.61 and it seems to flow and playback Flash video smoother most of the time.

UPDATE: As of October 9th, You Tube has once again "upgraded"(?) the Flash Player they use on their website. It now has an Auto button which seems to put every video in HD unless you move it down in Resolution or it will start over at the 10 second point. Annoying again...looks like this has been dropped as of November, too many complaints against it
As Of November 18th You Tube changed the look of its Home page and User pages with another Flash Player Interface and a slightly grayed background with controls moved around again

In Opera:config, Performance,
I would leave the Maximum Connections Server, Maximum Connections Total, Maximum Persistant Connections Server at their defaults instead of changing them, as it seems to be a "streaming" issue being handled by Opera and Flash Player.
I have found that the Network Buffer Size setting can be changed for better Performance.
It seems that the Default of 128 KB is good for a large Broadband connection like Cable. or an office network set up but not really needed at home for a stand alone computer.
If you have a slower connection like Basic DSL or Dial-Up, its better to lower the Network Buffer to just 1KB, since the data is streaming in slower anyways. This just lets the data buffer a bit before anything else happens so as not to overload all at once.
Then set the browser to redraw when loaded instead of 1 second and it makes an improvement.
So the Network Buffer at 1KB would help improve downloading overall.

Open a new tab and in the address bar type in opera:config

Look for the "Disk Cache" dropdown Menu

look down the list for Multimedia Stream Always settings

change the default setting from 0 to 1,
===================================================================
as of January 2012...
(I might be wrong about this after re-reading Opera's Help Info maybe the way its worded in opera:config means 0=in use and 1=off??? sometimes its written negative for a setting, really confused after trying this setting both ways.Maybe someone in the newsgroup might help, then again maybe not, this is a problem.)
I just tried the setting Multimedia Stream Always checked and that seems to be the one to keep the video stream constant without hiccups.
By checking this setting, it turns it on and puts a 1 in the .ini file.
So 1=On , Comments???
===================================================================
Multimedia Stream Always = 1

Multimedia Stream in RAM = 1

Multimedia Stream Size = 1024 (leave this setting as is)

Click "Save" then close that Tab and exit Opera and Re-Start the browser

Now the streaming video should run off of the available RAM in your Computer Memory chips rather than constantly using disk caching in OPERA.

To try some more time consuming experimenting...
Another helping tip might be to check the setting "Delayed Script Execution" so it waits a few micro seconds more when downloading a page. This allows a page to load without Javascript interference, until other items are loaded first for rendering, then it loads the scripts.
If the page doesn't completely load in Opera, try this setting if it might help.

in the address bar type in opera:config
go to Extensions
find "Delayed Script Execution", put a check mark in this, and click Save,close out the config tab and see if it loads the total page now without hanging.

After checking the "Delayed Script Execution" and watching the performance response, you actually might get a better rendering if you change the Time of the Script rendering in Milliseconds by increasing the "wait" time so other Elements load first and then the scripts to be more efficient in Opera since so many Websites are loaded with Flash, etc... and not just simple Text anymore.

Go To opera:config
Look for Performance
Look for "Reflow Delay Script"
Change this Setting,
from the Default 500 milliseconds = ½ second to 800,1000,1500,2000 or 10000,20000...
You have to try out the different settings for your setup.

500 milliseconds = ½ second
1000 milliseconds = 1 second
2000 milliseconds = 2 seconds
5000 milliseconds = 5 seconds
10000 milliseconds = 10 seconds

Click Save and then check your websites like You Tube.
You should notice how everything appears smoother on the page without n-1 hangs or choking on a page loading many elements. There can always be other reasons You Tube gets "stuck" due to their servers streaming or too busy at Google/You Tube.

I have done this and seen it actually help the "flowing" of a page render smoother.

Also take a look at
Changing the "Reflow Delay Load" which might actually help more but its on a custom basis for your PC based on the bandwidth you have to stream in text and video.
If you have a 50Mbps bandwidth then it probably doesn't need any tweaking of this setting.
If you have DSL or slower or an older computer, changing the Reflow Delay Load Time might actually help.( I have noticed an improvement with a higher setting)
The default 200ms seems to interfer more with the rendering like a buffer since the higher the number it will slow it down and make the screen display all at once instead of little by little.
By lowering this number to 96ms it seems to help the rendering engine draw the screen faster more in flow with its internal timings instead of holding any delay.

But if you raise the value to a higher millisecond amount like 800 , just a little more than ¾ of a second and have the script execution at 1500 on a DSL bandwidth it actually smooths the page flow when rendering with the display rather than piece by piece at a lower setting. It gives the CPU a chance to process it all since it has more Data.
I have seen a difference and like the slighly higher value to have a smoother look in Opera using DSL.

in Opera:Config
Go To "Performance"
Look for "Reflow Delay Load"
Change the number to a higher(DSL) or lower(15Mbps+) value depending on Bandwidth

Recent tweaking of settings have shown that a 750ms Reflow Delay Load and a 2500ms Reflow Script settings make a basic DSL connection much faster in Opera. It is time consuming but will give a better page load in OPERA without n-1 hangs, when you get the internal timings more customized for your setup.
HTH

Another twist to Flash videos on You Tube is to allow the cookie from Doubleclick to be set in the browser or the video won't playback. Google owns Doubleclick and will make you accept it or else not allow you to see videos. Also make sure there is no Host File entry blocking Doubleclick ads either.
However this might be bogus only if you use cookies, because by blocking all You Tube/Google cookies and 3rd party cookies, You Tube still plays videos but uses the "Flash Player LSO Cookie" (s.ytimg.com) to get around this.

YOU TUBE VIDEO STREAMING OBSERVATION

Saturday, July 10, 2010 11:53:01 PM

You Tube, Streaming, Video, Flash ...

Don't take this so seriously

Just have to Rant n Rave about this...

Wow can we Overload the "Flash" on You Tube anymore with all this HQ HD oversized videos constantly loading????

Why can't You Tube be like it was last year,or like in 2007 it was better before Google bought it, just a simple video box to watch, now it has to be Higher Quality, bigger screen size, advertisements, pop ups and before the video starts that you want to watch it shows an Ad !
Overloaded on many PC's that they freeze-up until its done!

So I looked on "My Account Settings" to see if something could be done to stop this incessant push to increase higher resolution video streaming in eating more bandwidth.

Found it,
Sign in to your You Tube Account, Under Your Username dropdown arrow in the upper right ,
go to My Account, then Playback Setup, under Video Quality Playback, select
"I have a slow connection. Never play higher quality video"
I also unchecked show Captions and show Annotations they are annoying too.

Yes now all that 'push' for HQ stops most of the time.
I'd rather have a quick video streaming at 240p than a slow wait and stall at 360p 480p or higher.
Besides a lot of video uploads are very low quality and HQ doesn't help it since they were made poorly.

I have DSL at 1.5Mbps its faster than Dial-up but I don't want to overload it with excessive broadband bandwidth "hogs" like 12- 25 Mbps ISP's.
This will probably help a wireless set up too.

Now You Tube works much more efficiently on DSL without all that extra overhead constantly trying to upgrade the streaming of the Video.

Google/YouTube just keeps remaking the pages with new scripts and ads almost daily trying to override browser settings and Flash to get you to use
Google Chrome

no wonder they have so many crash/conflicts happening! its overactive

Also see my other recent Blog Posts about ADOBE FLASH PLAYER and You Tube for other tips to help the Flash Player work better.
