I have everything installed and Jack working fine. I'm in the user group and have realtime enabled and running. My problem is that I can't get my input (the guitar) through rakarrack and out. This is how it is set up: Guitar is plugged in directly through the Input jack on the sound card (I have tried with the front input, rear, front mic, and rear mic inputs)
I have kde mixer set to allow pass-through of the sound from the input source (I can hear the guitar in my speakers, un-amplified directly from the source). The problem is that I cant get this source into rakarrack with jack to save my life. I have tried all sorts of combinations both physically with the audio jacks and in jack audio. Is that Jack isn't detecting the right input source with alsa or something?
I'm using a fedora install mainly for audio work and have everything working well out of the box. My setup is simple:
-Direct cable from Guitar 1/4" > Sound Card input>Rakarrack Guitar Effects>Ardour>System Out (Occasionally I put a synth/plugin like Zynaddsubfx or jackrack before or after rakarrack depending on what sound I'm going for)
-Jack for all audio transport with synthesizers
I have real time support with Jack and all other programs except Rakarrack. When I launch Rakarrack in the terminal, I get this message:
Code:
rakarrack 0.6.1 - Copyright (c) Josep Andreu - Ryan Billing - Douglas McClendon - Arnout Engelen Try 'rakarrack --help' for command-line options. Cannot lock down memory area (Cannot allocate memory) Cannot use real-time scheduling (RR/15)(1: Operation not permitted) AcquireRealTime error
However, running rakarrack in root does not display this output, and I assume it has no problem getting real-time scheduling in that case. I did some google searches but the only similar issues that I find are that people can't get RT support in jack except in my instance, I do have RT scheduling with jack, but for some reason I can't get it in rakarrack unless I'm root.
[Edit] I actually have to run jackd and rakarrack in root to get rakarrack to use real time scheduling. But, it isn't necessary for any other jack compatible program that I know of. I'm actually not getting any real time scheduling with any jack application, even though Jack is reporting to be running in Real Time. However, running everything in root fixes the issue even though I would prefer to not have to run as root.
I noticed that any CPU load, while using Rakarrack guitar effects, causes the sound to distort and it generates loads of noise. This actually happens when using anything while running Jack audio. If I'm recording, I get tons of noise on the recorded track when I play it back (and live when monitoring) because any CPU usage seems to interfere with the signals. It even does it live in the playthrough (monnitor).
I realized it had to do with CPU usage when I noticed a pattern with the noise correlating to the plasma CPU monitor widget I had running originally. The noise refreshed when the monitor did. Since then, I noticed that anything that puts a slight load on the system will cause this disruption (even moving a window around, or anything in the background processes).
Anyone who is experienced with Jack audio, and possibly rakarrack as well, know the cause to this? I figured loading a low resource WM and eliminating unneeded processes can help but it doesn't since the recording program itself, while recording, is enough to cause this problem. (I know this because playing the guitar in Rakarrack, without recording and just using Jack to run the sound to the speakers, doesn't have constant noise but when recording, there is a constant noise)
I'm currently using Debian Testing with Debian Multimedia Sid repos. The current Mplayer (3:1.0~rc4+svn20110308-0.0) seems to be broken - I can't encode AAC to AC3 on-the-fly anymore. I'd like to compile the latest snapshot or SVN version, but what is the easiest way to compile it with the same options as the one in debian-multimedia.org?
how-to compile from source; based on this post [URL]with some new hints and modified patches. This works on Ubuntu (Gnome version) without the official repository version of Amarok installed.

trying to install the latest version of Minitube on my 64 bit Ubuntu 10.04 installation. I thought adding a PPA would let me upgrade from version 0.9 to the latest version but it didn't seem to work. So now I'm trying to install from source (I've never done this before so I'm a complete noob when it comes to compiling). I checked the install instructions in the source which reads:
Code:
# Build instructions ## Prerequisites
To compile Minitube you need Qt >= 4.5 installed.On a Debian or Ubuntu system just type:
Windows and Mac users can get the Qt libraries from:
[URL]
Compiling on Linux is fairly easy. Just run:
qmake and then make
Beware of the Qt3 version of qmake! If things go wrong try running qmake-qt4 instead.
## Running
Just type:
./build/target/minitube
I installed the prerequisite packages,but just to be safe I wanted to run the ./configure command, but when I try to I get the "bash: ./configure: No such file or directory" message. Any idea what I'm doing wrong? Also, based on what I've read, I should have to enter some kind of install command in order to install the compiled binary but the instructions make no mention of this.
Configure: error: Unable to locate a suitable configuration of wxWidgets v2.4.x. The currently available configurations are listed below. If necessary, either install the package for your distribution or download the 2.4.x version of wxWidgets from [URL]. To help configure find the right version set WX_CONFIG to point to it. wxWidgets 2.5.x and 2.6.x are NOT supported! But I thought I installed widgets 2.4?
I am a happy Ubuntu user, I run it on all of my servers.
A few days ago I setup a new slice, and now I want to use it to convert ULAW (μ-law) WAV files into MP3's.
If I would only install LAME this would give me an 'Unsupported data format: 0x0007'. Because LAME doesn't support ulaw encoded wav's only Linear PCM's.
I have read that one can use the Libsndfile and use it with LAME --fileio=libsndfile (or something like that) when 'MAKE'-ing Lame. In this case because of the additional encoding library sndfile Lame can read and encode the ulaw into mp3.
I have also read another solution is to first convert the ulaw-wav into a pcm-wav with sox, and afterwards convert the output into an mp3 with lame. This seems to be a lot of extra system resources.
I am looking for a hands on tutorial howto wget, compile, install and run LAME with Libsndfile on Ubuntu Lucid (commandline only) so I can encode incoming ulaw files into mp3's?
I want to encode video content with mencoder and libvpx codec. I have libvpx installed on my machine and I can encode with libvpx using ffmpeg. My OS is Ubuntu 10.10, 64bit. I downloaded fresh mplayer/mencoder from SVN repository. If I configure mplayer/mencoder without any explicit enabled features using:
I am trying to compile OpenCV 2.0 with ffmpeg (with x264) support on my Ubuntu 11.04 64-bit machine. (Since I want to use the binaries provided by other developers, I have to use opencv 2.0 version)
I followed the guide from: [URL] to compile x264 and ffmpeg manually, and succeeded.
Then I followed the guide in the INSTALL file provided by the OpenCV 2.0 package. I use CMake to configure and generate them, and use "make" command to try compiling. However, I got the following error report, which haunted me for almost half a week.
Has successfully compiled Handbrake from source and got it to run? I've been trying to get this working for a while now, and everything I find on the interwebs is for Debian 7.6, and it seems as though things have changed a bit and those suggestions don't work.

Actually, it's recommended to compile (and build) wine 32bits. But, it's possible to build Wine in 64bits and 32bits with the same sources. The solution is explain in this page : [url]Building a shared WoW64 setup.
With this solution, if Wine 64bits is installed on your system, you can create a 32bits wineprefix by this command :
To use this command, you must to compile and make wine twice in 2 differents folder, like explain :
How to compile and make twice without problem in the "rules" files in the debian folder when i want to build a package?
The sysytem I use is Debian Squeeze. what's wrong but jackd2 from debian official repositories does not work with alsa (I have alsa-base, alsa-tools, libaudio-dev, libaudiofile-dev and libasound2-dev installed). Now I downloaded fresh jackd2 source from sourceforge and when I try to "./waf -configure" it it says that there is no alsa package or it's too old in the system and configures itself without alsa support.
I am thinking about alternatives for VirtualBox (which i like, but the Oracle-story is making me think). After this thread: viewtopic.php?f=10&t=56314 I downloaded the vmware-player (manual, not with the download-manager ) and installed it.

I'm installing ffmpeg with libavfilter using this guide but i can not get the movie filter to compile when passing --enable-avfilter-lavf to ffmpeg i'm using libavfilter r5935 and the test copy of ffmpeg.
I'm trying to get a DataVideo DAC-100 DV interface to work as a V4L device so I can get analog video into VLC to stream. I've got vloopback working but I can't get dv4l to compile. I've added the dev packages for all the prerequisites .configure was saying "no" to and that seems to be OK now:
As my previous thread about compiling the good old Amarok 1.4.10 for 9.10 and make it work properly again was well accepted, I post here the script for doing the same for the recent version 10.04.
In the old thread, there are some really great improvements like a better wiki-patch: [url]
Code:
The ~/ before Downloads makes sure, that you can run the script from wherever you are in your system (stands for your home directory). Further, omit the checkinstall line, as this is not necessary in a script.. The sleep commands in between allow users to check, if everything went fine before going to the next step.
I can confirm the above script is working and Amarok 1.4.10 is set up correctly on a justsetup system.
And yes, I was to lazy too write a proper error handling^^
I didn't perform any larger testing.. Open the program an playback worked. My iPod worked also including artwork.
By the way: Because of self-compiling, a nice little extension program is working again, amarokFS (FullScreen).

I want to learn how to compile vim from the sources, because there are some additions that I want to add, and learn how to deal with this situations, but until now I didn't have success doing it, I can compile vim, but without its GUI I think it's a dependencies problem, but I can't figure out which packages I have to install, what are the dependencies to compile vim with its gui? how to compile gvim, but I don't have the packages for install in my ubuntu 10.10 repositories.
this may be the wrong forum but how do i compile a .DEB from a tarball? and give me full step by step instructions preferebly for checkinstall since im not gonna distribute anything. none of that "./configure make sudo checkinstall" crap plz cuz i dont understand it i rly wanna switch from win 7 completely but ill need ur guyz help or im stuck with it T-T.
I suddenly can't compile anything using gcc - it just stalls (even with a basic Hello World program). I'm very stumped by this in terms of what might be wrong or how to go about finding out, so the best I can do for the minute is post the trace output (attached) and ask for some pointers.
I've been using ubuntu for the past year now but unfortunately I have to confess I never had to compile anything from scratch. I bought a new intel SSD drive and I've been running some benchmarks on it with various fs. The new hdparm version has a few features that I'd like to test (TRIM/wiper) but I don't know how to install it as it's not in the repositories. I've been googling for almost 4hrs now but I still haven't found a way to do it.
I've downloaded the tar.gz file from sourceforge and I've decompressed it. Inside, it was a debian folder but there was no .deb file in it. Anyway I did a "make hdparm" and it compiled with no errors. It gave me an "hdparm" executable which works fine if I call it with the full path. what's the proper way to install it in place of the already apt-get installed package?
