High definition video performance
location: ubuntuforums.com - date: May 5, 2011
I have installed ubuntu 11.04 on my computer. I have also instaled xbmc media center to see my movies. I have tried to play an HD movie (MKV with x264) and it doesn't go as smooth as it does in Windows (with Core AVC codec).
Following the information found in may forums, I tried to install:
- x264 package
- Ubuntu restricted extras
- w32codec package (from medibuntu)
- non-free codecs (from medibuntu)
After doing that, I tried it but nothing changed. I rebooted the machine with the same result. I don't know if it uses the new codecs or not. Is there any way to see what codec uses xbmc to reproduce a movie?
Any idea to solve the problem?
How to fix file extension wrong definition ubuntu 10.04
location: ubuntuforums.com - date: September 3, 2013
I have a file with extension .hal which is seen as a CAD drawing file, i have draftsight installed, the .hal file it's actually a text file so i need to open it with gedit, but if i set to open the .hal file with gedit, then all my .dxf file cannot open to draftsight, but they'll try open with gedit.
I would like to remove ubuntu from thinking .hal files are CAD drawings, because they are not, .dxf files open with draftsight, .hal files with gedit.
I hope there is somewhere to set this extensions settings, please help!

HD Video is in Standard Definition in Flash
location: ubuntuforums.com - date: August 18, 2013
When I try to watch HD video on the web, everything seems to be in standard definition. Videos that I download and watch on VLC are in HD, but flash videos do not seem to want to play in HD. I am using Ubuntu 12.04 on a ASUS ET2411INKI-B011K 23.6-Inch All-in-One Desktop The problem is especially apparent on NBC Sports Live Extra. The English Premier League streams are supposed to be in HD, but the picture quality looks worse than a standard definition television. Any help would be appreciated. I have tried the three different proprietary driver versions available in the additional drivers thing.
Edit: It seems that NBC Sports Live Extra is not supposed to be in true HD. The problem still exists on YouTube and other videos. 1080p flash video does not look 1080p. Everything looks like 480p.
a high definition question about VLC 2.0
location: ubuntuforums.com - date: February 29, 2012
ok so just updated to 2.0 using this route for 11.10
and first thing i did was to test a 1920x1080 vid to see if it now can handle that but noooooooo still stutters [SMplayer never has a problem with those]
which brings me to my question
2.0 is meant to experimentally handle Bluray and looking i see external drives can cost as little as 30 dollars/pounds/euros so i was thinking of maybe trying that
but since VLC 2.0 seems to still be in pain with 1080 maybe it is still too early for Bluray
now any of you already there and if so how is it going ? any tips?
PS maybe my 1080p problem with VLC has to do with my video output settings what would you guys suggest as optimum ?
Thank you in advance for all useful info

Where is the definition of Jiffy?
location: linuxquestions.com - date: April 26, 2007
i'm not sure if i should post this in the forum specific to my distribution (Debian Etch), but here goes anyway:
Where can i see what 1 Jiffy is defined as on my system? I have heard people say that a Jiffy equals USER_HZ, or 250 HZ, or 1/100 Seconds, or 1/1000 Seconds, and so on. Now, what i would like to know is this: is there a specific file, variable or whatever on my system that can tell me what it understands under 1 Jiffy? In case you are wondering, i need this information to be able to calculate the current CPU usage by parsing /proc/stat.
Thanks in advance,
I/O wait CPU percentage definition
location: linuxquestions.com - date: July 23, 2007
We run RH AS3 and AS4 in the enterprise.
The DB machines are fiber connected to a SAN.
We run Oracle DB (v9 and 10g)
On one application in particular (AS3) we have consistently seen high i/o wait numbers. The percentage would go as high as 99%, but more often it would be between 40 and 80%.
From my checking the OS is doing fine, it is waiting for response from the SAN. But should that keep the CPU's (4 of them) all at 80 or 90% busy?
What is the CPU doing at that time ....i know it's waiting for data, but what is it doing to make the % go so high.
I equated it to the CPU going to the door, and opening it looking for data, but none is there so it goes back to it's easy chair. Then ..it's still waiting so it gets up again and goes to the door.
The problem with this is we have 4 CPU's all showing that high i/o wait busy and management does not like my answer. Now I'm begining to question it and I'm looking for any info that might help explain what is happening.
