Programming :: Determine Which Device The Web Cam Is Using?
Aug 31, 2010When I run apps like mplayer to use my web cam it uses /dev/video#. For reason unknown to me this number changes and is usually either 1 or 0. I have looked on the Internet after struggling to find how to know which /dev/video device is used. So far I can only presume I have used the wrong terms to find how to determine which device the web cam is using.

Jul 2, 2010Is there a library/system call that will return to me what CPU core a thread of execution is running on? I've looked for a bit on the net already and also in /usr/include and couldn't find one.
getcpu() and sched_getcpu() are two that I found, but when I include the appropriate header files (linux/getcpu.h, and sys/sched.h respectively), gcc says getcpu.h doesn't exist and the linker complains it cannot find the implementation in sched.h.
I'm sure I'm doing something really stupid or overthinking...
What I am doing is running an OpenMP application and specifying a list of cpu cores to run on with GOMP_CPU_AFFINITY. I want to make sure that each core is getting the same number of threads.
**UPDATE**
It seems that this code works, but only with glibc >= 2.6, and my machine has 2.5:
Code:
#define _GNU_SOURCE
#include <stdio.h>
#include <utmpx.h>
int main( void )

Programming :: Use Quotation Marks In C++ Stream?
Jul 27, 2011I'm writing some code to speed up some code writing, basically it produces some code I use in every project. I produce the outputs with fstream filestr;, open a file and write to some data to it. However some code has quote marks that I need to output, however I can't use quote marks.
EG: filestr<<"#include "Header.h""<<endl;I get round this with some awful filestr.put ('"');However I'm sure there must be a straight forward way to do this. Can anyone advise?
Programming :: Non-root User Determine Which Days The Computer Ran?
Mar 22, 2010Is there any way a non-root user can programmatically determine which days the computer ran during, say, the last month?
The information is in /var/log/messages.* but those files are root:root 640.
Non of the world-readable /var/log files on the Slackware 13.0 development system can be used:boot Not present if boot logging not enabled (default). dmesg No timestamps. lastlog Not enough info. wtmp Rewritten on each boot so not enough info. EDIT: not correct: by default wtmp is rotated weekly and kept for one month as configured in /etc/logrotate.conf xdm.log Not present if xdm not used. Xorg.0.log Not present if X not run.

View 1 Replies View RelatedProgramming :: Perl: Determine Error Origin / Meaning In Code Call
Jan 20, 2010I've been requested to modify a perl backup script we use which mounts a networked NAS machine. The actual mount command is called inside a system() command. In testing, I can do a test of the return value, so I'm able to tell whether or not I've mounted properly, but I can't make heads or tails out of the return on deliberate errors. (Such as mounting a non-existent box.) I'm displaying the returned value, which is 256 in my tests. The man page for mount listed error messages with values from 1 to 64, but no higher. Am I drawing this error value from the system command somehow? And what would be the best way to determine what this error means?

All I know is that the sound goes through sound card to speaker system or in earphones, no matter the source.
How can I obtain the audio stream that I hear in speaker system or in earphones?
I would like to write an application that record and analyze the audio stream that I hear in my speaker system or in earphones. My OS is Ubuntu 10.04.

View 1 Replies View RelatedSoftware :: How To Set Bitrate For MPlayer
May 8, 2010Trying to play a *.mp4 video using mplayer and the picture is jumpy and the sound completely screwed. It say it is guessing the bitrate thus:
Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding)
FAAD: compressed input bitrate missing, assuming 128kbit/s!
AUDIO: 44100 Hz, 2 ch, s16le, 128.0 kbit/9.07% (ratio: 16000->176400)
Selected audio codec: [faad] afm: faad (FAAD AAC (MPEG-2/MPEG-4 Audio) decoder)
In fact the bitrate should be 139 or possibly 132. So assume that is what is wrong. Have assiduously coated myself with nourishing smegma and the like but am unable to work out how to set the bitrate in this case.
Software :: Same MP3 But Bitrate Changes On Different Distros

Discovered this using RhythmBox but also appears in Nautilus browser, under the properties tag.

Ubuntu :: Reduce MP3 Bitrate Using Lame?

I was wondering if someone would be able to explain the code and how I go about converting the bitrate to 96?
