According to 'man luvcview', if I do this:
Code:
luvcview -o testvid.avi
then luvcview should capture the video to the .avi file. However, when I try it, no output file is created. Grabbing a raw stream or raw frames works fine, but not the creation of AVI files. Am I missing something?
I've made a simple php wrapper around scp. It works fine, but unlike when I run the scp command straight from the console, there is no output returned. I've tried using passthru(), exec(), system() and shell_exec(), all to no avail. I'm redirecting stderr to stdout already.
For example:
PHP Code:
<?php
$command = "scp -C -r $files $target 2>&1";
exec($command, $result);
print_r($result);
?>
Will scp the files correctly to the server, but doesn't print any output - $result is just an empty array. I'd like to see the output so I can visually confirm that the files have been transferred correctly.
I would like to capture all output spewed to a terminal session including processes that are terminated that were invoked from a script running in a terminal window. this is beyond capturing just stderr and stdout . for example
{
./script
} 2> stderr.cap 1>stdout.cap
if script is terminated (including because of memory violations) I get spewed output to the terminal I would like to capture that spewing to a file automatically or to a bit bucket /dev/null Is there another filehandle which can be redirected to do this? If so how or is there another way???
I run a 3rd party command line utility and it works fine, but sometimes it says "Error blah blah blah... Connection timed out"
I want to script this utility, but I need to not execute the commands in the script if it gives me that connection timeout error.
bash code to capture that response from the utility? Something along the lines of:
Quote:
#!/bin/bash
3rdpartyutil > /tmp/temp.txt
if [ ! -f /tmp/temp.txt]; then
echo no error, run whatever you need to man
fi
rm /tmp/temp.txt
Unfortunately, that doesn't work because the utility outputs non-error information to the screen even when it is successful, so it always outputs something, I never need to see it, but I do need to be able to act upon if some of that text says "error" or "connection timed out"
I have a file which contains a table
row1 ✔ no ✔ no
row2 no ✔ ✔ no
... so on
I want to prefix the number of ✔ to corresponding row If I use the command :.s/✔//gn I get output written like '2 matches on 1 line' How can I extract the '2 matches' in above case ?
I want local programmatic access to ssh output in Mac Terminal. First, I tried redirecting the output of each command to a file. The file was perfect, but of course it was on the remote server, and an sftp for each command output seemed a little.. Next, I tried to Applescript Terminal, but it only gives access to the currently visible text in a tab (i.e. if half the output has already scrolled out of sight, it doesn't get returned - useless).
Last, I tried piping ssh to tee (e.g. ssh user@host | tee output.txt). This almost worked. I have the output in a local file, but there are a lot of unwanted characters mixed in. For example, every time I hit backspace, there's a ^H in the file. There's also text like "[0m[K" which is harder to get rid of.
I've tried to look up different programs for this but can't find anything. I'd like to be able to open my recorder on Myspace for instance and capture any sound playing through my speakers. I used to have a little program for this, but its windows based and won't seem to install correctly in Wine.

I've been trying for a while now to capture videos with my webcam of my samsung n110 netbook, I am running ubuntu 10.4 and cheese 2.30.1. I can take pictures fine, with effects and everything but when I press "start recording" the webcam seems to turn off or all I see is a black image, then when I press stop recording the camera picture comes back on and then the program freezes. I've tried turning down the resolution, I've tried all the possibilities in gstreamer-properties but nothing helped so far running from terminal didn't give me a clue on what the problem might be either. I would like cheese to work to have photo and video in one program but if someone has a good program to capture video I am willing to try it out.
View 8 Replies View RelatedI have a unlisted remote which I can't find a lircd.conf for. Have tried irrecord with a mceusb receiver and have had no success. I am running maverick on a fresh install. LIRC is install and functions correctly for MCE remote and sending dishnetwork ir codes. I have found the hex codes for it but have no idea what to do with them even if there is anything to do with them. My question is this, is there any other way to capture the remote codes other than irrecord? Is there a way to manually build the codes?

First how do I get HDMI audio output to my TV? I think I have just a integrated Intel graphics card. It works fine in windows but I can't seem to get it to work in Ubuntu. I tried searching but couldn't find anything pertaining to this issue.
I am sure that this is very simple but I have installed sound juicer and the gstreamer plug ins. The problem is i still cannot select MP3 as an output output option
View 3 Replies View RelatedI'm still trying to find out if my coby mp3 player will actually play mtv video files as is advertised.
ffmpeg -formats does list mtv but the only command I really ever used was one to convert a vid to an mp3 so I tried Code: ffmpeg -i test.mp4 -acodec copy output.mtv it returns Code: Unable to find a suitable output format for 'output.mtv' I can't find any mtv files online for purchase or free for that matter, so I know this is all pretty obscure but shouldn't there be a way to convert them since ffmpeg lists mtv format?

View 2 Replies View RelatedI have four primary partitions currently. I need to keep all of them. I need to make a fifth that is also a primary partition. Is there a way to somehow make a partition into a partition that's in an extended partition without losing any data? Maybe you know of another solution to my problem, but this is the only one I can conjure up. The second problem is much less severe. I can't find any screen capturing software for Ubuntu that will record my desktop and simultaneously record sound from a microphone.
View 9 Replies View RelatedSo I've noticed that some applications block keystrokes and input from reaching Ubuntu. Most recently I got the Linux version of Unreal Tournament 2004 running. Problem is that when I'm playing Unreal it captures all input, so when I decide the game is too loud or too quiet, rolling my volume wheel doesn't adjust the volume. I either have to pause the game so it releases my mouse(only in windowed mode), or exit altogether, adjust the volume, and restart the game. Is there a way to change this?

I can't seem to figure out the secret to send ctrl-alt-del to a remote Windows box using KRDC 4.4.4. Tried in windowed and full screen mode - no difference. Tried enabling "Grab All Possible Keys" in KRDC tool bar - nope. In all cases, ctrl-alt-del and alt-tab are sent to localhost. There are some mentions of a "config special keys dialog" for KDRC in a few places, though I don't actually find this anywhere in KRDC itself. Documentation for KRDC at the KDE site is very minimalistic. This should be super simple, but I can't quit seem to get it.
