Bad video quality

Post by Tar_Ni »

Hello,

I have a problem on Linux Mint (as well as Ubuntu) which is that streaming videos are unwatchable. With the open-source (xserver-xorg-video-ati) driver it's really slow and the video doesn't quite follow the sound and I just can't watch videos of that quality.

So I installed the proprietary AMD driver, (fglx-updates) and while it did improve the quality, the video are still suffering, especially on faster scene where horizontal lines appear.

Note that I just can't watch any video in full screen or High Definition regardless of the driver in use, the lags and waivy lines are way too painful.

I don't have that problem on Windows, which I had installed on this computer just last week.

PC specs:

Asus motherboard
AMD Radeon Graphics HD 6920
AMD C-60 1.00Ghz processor
4 GB RAM DDR3
HDD 320 gig

OS:

Linux Mint Cinnamon 17 LTS

Some people posting on the internet claim that the problem is XServer intermediary between application (responses), and if XServer was gone, that the application response/no or little tearing would result
--the difference between Windows and also Apple OSX and graphics drivers is that the OS directly supports the GUI look/style and operations..
  • And of course they get results from graphics card manufacturers
    --which Linux and OSS have no access to..
They are saying Wayland and better compositing would help

You may be able to adjust XServer optins to improve operations..

--there is possibly an OPENGL driver that could also help

Video players such as VLC or Mplayer could stream locally and provide a clean video show, I would think..

''I don't have that problem on Windows, which I had installed on this computer just last week.''
Use Windows then :roll: .
EDIT I am not being facetious; you have a modern kernel, a proprietary driver, loads of RAM, a modern processor, two Linux distributions are unsatisfactory, and Windows works better.

Thanks DrHu but I don't seem to find a solution in the links you provided. I am a Linux ''newbie'' so I am looking for a clear step-by-step solution to adress this problem. I am not accustomed to the technical side of Linux.

Your reply is not very helpful. I mentionned that I did not have this problem on Windows, which came pre-installed on this laptop, to point out that this is not hardware malfunctions/defects and so the issue is clearly Linux-related. It happened also on Ubuntu 14.04 which brought me to try Linux Mint Cinnamon but same thing again.

Going back to Windows would be as a last resort, if I can't get things to work properly. I don't want to go there but I purchased this laptop for the main purpose of watching online videos. Linux is great I had it on my older desktop computer (Xubuntu and later on Mint XFCE) and worked flawlessly. I never faced this kind of issue before.

Thanks

I also noticed that you said streaming videos ?

1) What are you using to watch these streaming videos?
2) are local videos working ok ?
3) Did you try VLC?

I am watching streaming videos online in such websites as Youtube, Dailymotion, MovPod, GorillaVid, CloudZilla ect. As I said above, never had any problem watching videos on these websites.

I've tried the latest pepperflash of Google Chrome but it didn't help, so it doesn't seem to be the older 11.2 flash player plugin itself.

Strangely video are fine in VLC Media Player, I've tried a DVD and it plays correctly, the graphics are decent.

strange but let's just try one thing to exclude the obvious.

reboot into a live session (your installation dvd or usb) and go to one of the sites to see if it works.

Tried to watch videos in live boot but pretty much the same. Full screen is useless, the quality is too bad due to choppiness and lags.

The drivers (both open source and propietary) just don't seem to offer decent performance with my graphic card on Linux. I am really at a loss as to what to do. Would I have more luck in say a completely different distro such as Fedora?

Thanks.

Hi,

nobody can answer this you have to try it.
A PC is a complex system ,yours seems to do ok with local videos but crap with streaming...it takes a bit of time to get all the settings right.
Also are all the codecs ok and installed? (guess it is but you may want to try different video files, not DVDs the encoding on them is standard and meant to work on all appliances...) Video files however can be different depending on the method used to create or reencode them.
Did you try a fresh install of chromium?

Hi,

I'm a noob myself, so take anything I say with a pinch of salt.
But I too have an AMD graphics card (5670) and I switched to fglrx but still found the video to be choppy, especially HD.
As suggested earlier in this thread, it did seem to me, to be to do with the compositor.
I'm on Linux Mint 17 Xfce, and for me the solution was to switch off the built in compositor, and install and use Compton instead:
http://duncanlock.net/blog/2013/06/07/h ... g-in-xfce/
I'm now happy with the video on my machine, but maybe this only applies to Xfce and won't help you.

Cheers

Hi,


this workaround does help videos but it also disables other features that are used by the xwindow (you might later on get other kind of problems)
Again as I said linux is an open box, you have to put some work in it to get it working the way you like it. What works for one doesn't always work for others.
But you seem to be on the right track, you have to test things and feedback to share your experience, it's a community and doesn't compare to more commercial OS :wink:
