Linux Sensors

Q. How do I read CPU core temperature data from a shell prompt under Linux operating system? How do I monitor my cpu hardware?

A. You can use Linux hardware monitoring tool such as lm_sensor. This tool provides some essential tools for monitoring the hardware health of Linux systems containing hardware health monitoring hardware such as the LM78, and LM75.
This tool use the System Management Bus (SMBus or SMB), which is a simple two-wire bus, derived from I²C and used for communication with low-bandwidth devices on a motherboard, especially power related chips such as a laptop's rechargeable battery subsystem. Other devices might include temperature, fan, or voltage sensors; and lid switches. PCI add-in cards may connect to an SMBus segment.

Install lm_sensors / lm-sensors package

This package may or may not be installed. Type the following command to install software on CentOS / RHEL / Fedora Linux:
# yum install lm_sensors
If you are using Debian / Ubuntu Linux, enter:
$ sudo apt-get install lm-sensors

Configure lm_sensors

To detect hardware monitoring chips, type the following command as the root user:
# sensors-detect
OR
$ sudo sensors-detect
Sample output:
# sensors-detect revision 4609 (2007-07-14 09:28:39 -0700)
This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 0000:00:1f.3: Intel 82801G ICH7
We will now try to load each adapter module in turn.
Module `i2c-i801' already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.
To continue, we need module `i2c-dev' to be loaded.
Do you want to load `i2c-dev' now? (YES/no):
Module loaded successfully.
We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.
Next adapter: saa7133[0] (i2c-0)
Do you want to scan it? (YES/no/selectively):
Client found at address 0x47
Handled by driver `ir-kbd-i2c' (already loaded), chip type `Pinnacle PCTV'
    (note: this is probably NOT a sensor chip!)
Client found at address 0x4b

Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!
Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM78-J' at 0x290...     No

Probing for `IPMI BMC SMIC' at 0xca8...                     No
Some Super I/O chips may also contain sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'...                   No
Trying family `SMSC'...                                     Yes

    (but not activated)
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'...                   No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Fintek'...                       No
Trying family `ITE'...                                      No
Some CPUs or memory controllers may also contain embedded sensors.
Do you want to scan for them? (YES/no):
AMD K8 thermal sensors...                                   No
Intel Core family thermal sensor...                         Success!
    (driver `coretemp')
Intel AMB FB-DIMM thermal sensor...                         No
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `to-be-written' (should be inserted):
  Detects correctly:
  * Bus `SMBus I801 adapter at 4000'
    Busdriver `i2c-i801', I2C address 0x2e
    Chip `Andigilog aSC7621' (confidence: 5)
Driver `coretemp' (should be inserted):
  Detects correctly:
  * Chip `Intel Core family thermal sensor' (confidence: 9)
I will now generate the commands needed to load the required modules.
Just press ENTER to continue:
To make the sensors modules behave correctly, add these lines to
/etc/modules:
#----cut here----
# I2C adapter drivers
i2c-i801
# Chip drivers
# no driver for Andigilog aSC7621 yet
coretemp
#----cut here----
Do you want to add these lines to /etc/modules automatically? (yes/NO)
This is an interactive program that will walk you through the process of scanning your system for various hardware monitoring chips, or sensors, supported by libsensors, or more generally by the lm_sensors tool suite. For my system coretemp and i2c-i801 driver need to loaded in order to see sensors data. Type 'YES" to update /etc/modules files. Now you need to reboot the box. Alternatively, you can load all drivers using modprobe command
# modprobe coretemp
# modprobe i2c-i801

How do I read sensors chip data such as temperature?

Type the following command at shell prompt:
$ sensors
Sample output:
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +59°C  (high =  +100°C)

The thumbnail too slow with ffmpeg

I have a project with video Encode in this month. I have a trouble with respone of ffmpeg thumbnail too long. But I have fixed it today. Now. I will show the problem.

The command I used :
ffmpeg -itsoffset -40 -i BG.mp4 -vframes 1 output.jpg
See in this command. It's will take a snapshoot at frame 40 from the start frame. And by this way, you have to wait for ffmpeg seek to the frame's Index 40. That's find. But thinking about offset 100,000 or more?. I see it's take long time.
You can this command for "little exactly" but much faster.
ffmpeg -ss 00:00:50 -i BG.mp4 -vframes 1 output.jpg
the ss parameter is time seek of video. That's make thumbnail much faster than seek by frame. You can calculate the -ss parameter by:
ssTimeInSec = FrameOffset / FramePerSecond
I write a PHP code to translate TimeInSec to time in -ss parameter.

 function translateSecToString($sec){  
  $sec = intval($sec);  
  $h = intval($sec / 3600);  
  $m = intval(($sec - ($h * 3600))/60);  
  $s = $sec - ($h * 3600) - ($m * 60);  
  if($h < 10){$h = '0'.$h;}  
  if($m < 10){$m = '0'.$m;}  
  if($s < 10){$s = '0'.$s;}  
  return $h.':'.$m.':'.$s;  
 }

Hope it can help :D
