Video strem is slow on youtube

THE PHANTOM · 12-16-2016, 11:43 AM

Hi,
I have such trouble: When i watch movie on Youtube or other portal of movies video stream/play is very slow.

Please see that screencast: http://www.4shared.com/video/0zZ_9XmOce/3_online.html

My graphic is:

Code:

00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri [Radeon R6 Graphics] [1002:130a]

I added That on: /etc/apt/sources.list

Code:

# Debian 8 "Jessie"
deb http://httpredir.debian.org/debian/ jessie main contrib non-free

after:

Code:

# apt-get update

Code:

# apt-get install firmware-linux-nonfree libgl1-mesa-dri xserver-xorg-video-ati

and reboot.

But same nothing changed. On system loads up with title there is : http://i57.tinypic.com/96e2v7.png May it be reason of it?

what can i do? Thanks in advanced.

Those boot messages just say that the backlight brightness of your (laptop) screen could not be restored to the level before reboot. That should not impact performance at all.
I'm on Sid and when searching for kaveri, I get packages named xserver-xorg-video-amdgpu and xserver-xorg-video-radeon showing up. Could xserver-xorg-video-ati be the the wrong one? (I don't have a kaveri graphics card, so I can't test it.)

# apt-get install mesa-utils

$ glxinfo | grep -i direct

Should be "Direct Rendering: Yes". If it's not, then you're not using the right video drivers or your permissions are messed up.

$ groups; id

The user should be in the video group. And several other groups.

Beyond that the browser cache's videos to your /tmp/ or ~/.cache type places. If your storage medium is slow, that can cause buffering due to file I/O. Various mount and ramdisk ways to cope if that's the case. Otherwise youtube-dl is your friend.

Code:

  # apt-get install mesa-utils

i will install that.

That is my own laptop and no one uses it, how to make my user to all group members? if that is problem i will try it too.

i have one question too: is possible to have wicd network manager and built in network manager both same time, will they make conflicts to each other?

Thanks for your supports.

One network manager will likely conflict with the other. At a minimum one will get used, the other not. I just install dhclient(isc-dhcp-client) and wpasupplicant. Or network manager if for others since nmtui is a thing and is kind of nice. It's fairly easy to disable them now.

# service <name> stop
# service --status-all
(to list known services in debian)

Although ModemManager doesn't seem to play nice in that realm so old school it with kill or systemctl. Although I'm the exception and a minimalist. Kind of have to be when your best machine is 2GHz and 2GB ram. Having an extra 100MB ram free is like gaining 5%. So not running pulseaudio +5%, not running network manager +5%, not running chrome ???

THE PHANTOM · 12-17-2016, 11:19 AM

Code:

glxinfo | grep -i direct
direct rendering: Yes
    GL_ARB_draw_indirect, GL_ARB_draw_instanced, 
    GL_ARB_multi_draw_indirect, GL_ARB_occlusion_query2,

I ran that command

Code:

glxinfo | grep -i direct

so it is right driver right?

THE PHANTOM · 12-17-2016, 12:32 PM

I can not watch movies. it is so laggy stream

Shadow_7 · 12-17-2016, 06:18 PM

Are you buffering?

$ speedometer -r <internet_interface>
if it's a flat line you're network connection is like maxed (internet speed)
- change the stream rate to fit your pipe

$ nmon
press "l" for CPU, if BLUE you are waiting (probably on storage / swapping or /tmp)
- get faster storage or use a ramdisk

Use kernel+firmware+mesa+libdrm+xorg drivers from jessie-backports. Although xserver is old in jessie (you need newer for better glamor support).

What is the output of:

Code:

glxinfo |grep Open

?

THE PHANTOM · 12-18-2016, 06:37 AM

glxinfo |grep Open

Code:

glxinfo |grep Open

I downloaded latest kernel 4.9 version. can u help me how to update my kernel with it? i have it extracted on my home directory. Thanks.

gradinaruvasile · 12-18-2016, 10:50 AM

Best is to use the kernel (4.8.11 now) and the rest already packaged from backports:

THE PHANTOM · 12-18-2016, 11:28 AM

I update system today, kernel too, but nothing stream is same leggy. First when i install Debian Linux x64 bit i had not that problem but i had wifi trouble with x64 bit, because i tried to installed x32 bit and solved wifi trouble but occurred that one stream.

BW-userx · 12-18-2016, 01:35 PM

anyone ask how fast is your connection?

THE PHANTOM · 12-19-2016, 01:23 AM

Sorry. My connection is normall. i test it with others devices and no problems on it.
