Poor quality video playback in browsers - light - 08-06-2014

Hello all,

I'm experiencing poor quality video playback in my browsers. Video playback in XBMC is flawless.
Initially I just tried Firefox on a fresh install and youtube looked bad, tearing and stuttering. I
tried Chrome thinking it was specific to Firefox, same thing with Chromium. Tried uninstalling
flash and reinstalling, same problem with video playback.

Hardware is capable, not flashy:

P4 2.8ht / also tried on a Pentium D 3.4
4 gig ddr2
hd7750

Other distros run on this machine run youtube with flash perfecty in 1080p.

If i set html5 on youtube it works... and as mentioned above XBMC running on Linux Lite, video
playback works great.

Flash is up to date (for linux), LL system is fully updated, processor has SSE.

Any suggestions on a fix would be appreciated. I really like Linux Lite.

Thanks for reading

Hello light, open a terminal and type:

Code:
cat /proc/cpuinfo | grep flags

Look in the output for anything with "sse" in it. You are looking specifically to see if "sse2" is listed? If it is NOT listed and you only see "sse", then you need to use an older version of the flashplugin. If you only see "sse" try this post here - https://www.linuxliteos.com/forums/index.php?topic=160.msg797#msg797

Thanks for replying Valtam, yes it does show sse2, I'd checked earlier and even tried installing the
legacy flash from the repository just to see if it made a difference. It didn't improve it, so I switched
them back, currently on latest.

here's the output:

Code:
flags        : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 

clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc pebs bts nopl pni dtes64

 monitor ds_cpl cid cx16 xtpr

pae is there and I'm on 64 bit Linux Lite, maybe that info helps. I was thinking of trying 32 bit to see
if it's the same.

Just tried the 32 bit live, same problem. Double checked the 64 bit iso checksum, all good.

Sounds like you've just about run the gauntlet of things to try here, someone else may pop along with the right fix.

Re: Poor quality video playback in browsers - light - 08-07-2014

Thanks Valtam,

I've found a slight workaround at least for the youtube videos playback quality and size issue.
Maybe this will help someone else in a similar position who happens to be reading this,
just incase youtube would be a dealbreaker for them. Linux Lite is pretty awesome.

There's an app in the repository called smtube you can run it with vlc etc
It'll be listed in Multimedia afterwards.

This is the video I like to test with:

Runs perfectly in 1080p maxed on my 32" screen.

Hi light,
Have you installed your drivers?
If you have try this Flash Plugin
http://packages.linuxmint.com/pool/import/m/mint-flashplugin-11/
In Chrome you can enable hardware acceleration
Check if it's enabled with chrome://gpu
If it's not then type this in your browser chrome://flags
Search for "Override software rendering list" and enable it then check again in chrome://gpu
Test 1080 video with and without hardware acceleration
If nothing works then you can use Smplayer with Smtube or Qmplay2
Cheers Smile

Thanks for posting misko, all of the above were tried, I reckon I'll stick with
smtube for full screen 1080p for now. I'm planning on testing some slightly older
graphics card and perhaps older version of LL to see if it makes a difference. I've noticed this issue
with all the Ubuntu based distros I've tried on 14.04. So I'm thinking I'll try that out and some
other things when I get the time. No worries and thanks for your time ;D
