Ubuntu :: Audio Skipping In Java Application
Jan 18, 2011
I just installed Ubuntu 10.10 last evening and all has been going well. Lucid didn't work out for me, so I used other distros. 10.10 fixed all issues except one thing. This is a need for me; e-courses I take require that I use Elluminate Live, a Java-based conference software. It runs flawlessly on every distro except Ubuntu. I had to use another PC running a different distro in order to get to a class. I really don't want to do that all the time. I thought it may be OpenJDK, but I found that Sun Java was installed and in use (I installed the extras while installing). I tried OpenJDK (worth a shot eh?) and the exact issue persists. All other programs have perfect audio.

So I did a short 30 second video of Recordmydesktop in ogv, and was wanting to convert it to mkv. So when I did the video was awesome but the sound kept skipping. Here is the conversion command i did
Code:
ffmpeg -i test.ogv -vcodec libx264 -vpre medium -crf 24 -threads 0 -acodec copy test.mkv video was great, audio not.

I've just made the move to openSUSE* and after the installer seemed to bork my xorg.conf because of my Wacom tablet things have been going quite smoothly. My only problem at the moment is that MP3 playback through Exaile, Banshee or Totem stutters and pauses several times per track or more. The only commonality I can see is GStreamer, but nothing is giving me errors to the console.
Code:
rpm --query --queryformat '%{NAME}-%{VERSION}-%{RELEASE}-%{ARCH} -> %{VENDOR}
' gstreamer-0_10-ffmpeg gstreamer-0_10-fluendo-mp3 gstreamer-0_10-fluendo-mpegdemux gstreamer-0_10-fluendo-mpegmux gstreamer-0_10-plugins-bad gstreamer-0_10-plugins-base gstreamer-0_10-plugins-good gstreamer-0_10-plugins-good-extra gstreamer-0_10-plugins-ugly
[Code].....
* I ditched Fedora to get better Monodevelop support after using Redhat 7.3 and 9 followed by FC 3 and 6 then Fedora 7, 8, 9 and 10. The Ubuntu forums seemed to keep giving me occasional answers to questions, but the Suse build service gave me the RPMs, when the requirements matched.

Check 2 in your error-check show this:
error: rpmdbNextIterator: skipping h# 1022 Head V3 RSA/SHA256-signatur: BAD, key-id 3dbdc284
Is there a serious error or is just the whole multi-media package missing. I have installed 11.2 from live CD.

So, I have this application called Impact, it is an explicit time integration Finite Elements code written in Java...
[url]
I untar the pack, and launch the application calling a script, from within the untarred folder,
Code:
This launches a gui which allows me to setup a case, which needs some setup file, tipically some *.in and a mesh file, tipically some *.msh.
Other mode of executuion consists of calling the setup file as argument to Impact.sh script ( CLI execution mode, for g33k5 )
My problem is : I have packed the whole stuff into a Slackware .tgz, that places it in /usr/local/Impact, and placed a calling script in /usr/local/bin,
Code:
Code:
I decided to hack the ImpactGUI_OGL_linux_amd64.sh script from
Code:
Code:
no avail,
Code:
even after adding /usr/local/Impact/bin to PATH... won't go...
I can run this thing from within its directory... but I do not like messing within the directories of my applications, this is why I sent this to /usr/local, and placed a calling script in /usr/local/bin...

I upgraded to Ubuntu 10.10 on my Macbook and now I am noticing that when I'm listening to audio via web browser or banshee, it makes a skip like noise every 10 or 15 seconds. I do not notice this issue when playing games or anything else.

I"m running 10.04 on a netbook. I switched my Java look and feel to Nimbus and now my java application opens with most of the buttons and window content missing. The main menu is there, but otherwise the main form is mostly blank. If I restart the application (not my computer) 2-3 times, the problem is resolved until the next time I have to launch the java app. I did not see this issue before changing the look & feel setting for Java. But the GTK l&F doesn't work for other reasons, so I was forced to make a change.
I'm running compiz and I know the blank windows in Java apps was a common problem a while back. I'm not sure if what I'm seeing is related to that old problem or is something different.

When I run a java application (minecraft) the computer occasionally freezes. I'm not sure which version of Java I have. The online java app for telling you which version I have says that I have an old version. The command line says I have an up to date version. If I need to update Java Sun , how do I do it ? I followed the instructions once and didn't work.

There's a site where you can play classic NES games online without any installation, just need Java: nintendo8.com. But when selecting a game from the site's game list and it tries to load, I get this error:
icedteanp plugin error: Failed to run /etc/alternatives/../../bin/java. For more detail rerun "firefox -g" in a terminal window.
I then ran "firefox -g" from terminal, tried again and got this log:
ERROR: Invalid browser function table. Some functionality may be restricted.

I have Java up to date from its repository.

We have an in-house developed Java application deployed on Red Hat Enterprise version 6.0, on an IBM hardware X3630 N3 model 64-bit server with 6 core processors. Apparently, when the application is running, it is picking up only 2 processes, at random. Hence, the load is not being distributed equally and occupied processors are showing 100% utilisation. How to resolve this so that all 6 processors are being utilised for proper load sharing.

Ok I just downloaded this program called Phex, it is a really cool program and i get it to run, but only from command line. I downloaded this program and its already compiled and works fine but i can only launch it from a command line by typing "java -jar phex.jar" I have created launchers before and they have worked, but this one just doesn't work. I have all permissions on the directory and the files, but how to create a launcher for this file.

For some reason Java Applications running through Firefox have no audio, Java applications running through the java -jre command do run with working audio though. I don't know what else I need to post, but this is what I've been getting. Audio does seem to work with most of my other applications and games.

java: /build/buildd/openjdk-6-6b20-1.9/build/../pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream.c:680: Java_org_classpath_icedtea_pulseaudio_Stream_nativ e_1pa_1stream_1cork: Assertion `stream' failed.
I keep getting this error about 1-10% of the time when a Java application tries to play audio. When this happens, the whole JVM quits, which means the crash is in native code. I find it difficult to test my Java games, for obvious reasons, since I am a Java developer primarily. I use Eclipse 3.6 SR1 to develop my Java apps, and I'm a recent convert to Ubuntu from Mac OS X. EDIT: Whoops, forgot to mention that I'm running Ubuntu 10.10 "Maverick Meerkat" x86_64 version.

i cannot seem to find a proper way to make Java my default application to open .jar files. I just made a new Debian 8.3 install on my laptop HP Pavilion G6 and the default application for opening .jar files is the Archive Manager. But when i go to "Open with.." section on right-clicking the .jar file, i get no JRE or JDK option to choose. I just installed the openjdk 7. I can manually run them from the bash, but it would be much more convenient if i just double-clicked it. Here is what i get when i run several commands in the bash :
1) which java ->Code: Select all /usr/lib/jvm/java-7-openjdk-amd64/bin/java
2) java -version -> Code: Select alljava version "1.7.0_95"
OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-1~deb8u1)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
3) echo $PATH: Code: Select all/usr/lib/jvm/java-7-openjdk-amd64/bin:/usr/lib/jvm/java-1.7.0-openjdk-amd64/bin: /usr/local/ sbin:/usr/local/bin:/ usr/ sbin:/usr/bin:/ sbin:/bin
4) javac -version : Code: Select alljavac 1.7.0_95

I have these "out of memory" issues with fedora 13 64bit. previously we had centos5, the same environment in terms of programs used, nevr experienced these problems. the issues are for instance a java application already started stops suddenly, or won't even start.
example from tomcat stop:
[code]...
The one thing i don't understand about these numbers is where it goes all that used memory. i only listed the top 40 tasks out of 200 in order of physical ram used, can it be that even if it "sees" 5gb it cannot use it all, just like say windows7 and usable memory? (I recently troubleshooted that one, where out of 12gb w7 reported 8gb usable, I solved that by reverting the cpu overclocking.)

I am currently taking a Java class and I am not understanding it very well. I have compiled the following program, but it will not give me any data back to where I input the employee name, hours, rate. Can you look it over and tell what I am missing? I have been working on this for about 7 hours now and I have been reading and researching and just can not seem to know what is missing.

I'm trying to make a java application in netbeans 6.9.1 (ubuntu 10.10) and I need to use the webcam on the system. Now I found this project: [URL] I am able to run the program and see the vid imput from the webcam using: "java -cp /usr/share/java/v4l4j.jar -Djava.library.path=/usr/lib/jni au.edu.jcu.v4l4j.examples.DeviceChooser" The problem is how to import the libaries into netbeans, there is an explanation on the site how to do it with eclipse but I don't have any experience with ecplipse and judging from what people have to say about how it works I don't want that either. I get the following error as output:

I'm looking into building a media server that will output to 2 channels. I'd like to use Ubuntu however, if there's a better alternative, I'd be open to using it. I'd have 2 audio and video cards for output and what I'm interested in knowing is if there's a way to set the audio output to a specific card per application or workspace. Is there an easy way of doing this?

I am trying to record audio playback from an application and the microphone at the same time on recordmydesktop using pulse audio. I just can't figure out how to mix them both. I have tried a lot already and can only get either the mic or the audio playback to be recorded, not both. Can this be done using pavucontroll?
I have been search now for hours to find a solution (also here on the forum) for this and getting really frustrated now. Maybe i'm just missing something really obvious, so sorry if this is a stupid question.

I currently have my desktop setup with two displays, one of them being my living room tv that I run Boxee on. My problem is that all the audio runs through the same speakers preventing me from listening to music or gaming at the same time as when Boxee is in use.
I would like to know if it's possible to split the audio so that an application of my choosing only outputs sound through my headphones. I was thinking it would be possible with some of the controls in pulse, but if it is I cannot figure it out.

I switched to OpenSUSE last month, and so far so good.But one thing that I haven't found yet is a CD ripping program. Yeah, I know, Amarok and K3B will both do it, but both seem a bit fiddly to configure and both are massive programs and seem to be over the top for what I want. When I used Ubuntu/Gnome I used GRip, and latterly RipperX, both of which do pretty much what it says on the tin - they rip CDs. And that's it. I'd prefer this kind of approach than the 'everything plus the kitchen sink' that I get with Amarok and K3B.Is there any kind of lightweight CD ripper in the OpenSUSE repos?

I am looking for a nice and simple GUI app that can handle multiple audio formats and convert between them, something like Xrecode in windoze. Maybe by any chances you know about such alternative or similar application
If no such application exist, then i would like to find some solution for easy conversion for these scenarios:
Mainly i keep my music collection in flac format, so i mostly care for conversion from other formats to flac.

My wife is reluctant to move from WinXP so I started my own personal campain to promote fedora at home but my wife complains that I "spend too much time fidling with the thing(PC)" and that "it wasn't the case with WinXP" so I =was looking for ways to impress my wife with fedora's capabilities so I flashed her with compiz and dual screen using our old 52" projection tv as a DVR but rhe problem is that my daughter want to watch her DVDs and my wife want to watch a ..... video.I have a system with two Sound card one embedded on the main board and one on a PCI slot and what I am trying to achive is haveing two applications, like two instances of VLC play their sound on the souncard I select per instance, or one Sound card playing VLC and the other playing a ..... video's sound.
I have looked at pulse audio properties and it detects both of my sound cards just fine and it plays wonderfully on either but that is just it... it will pay on either but not both.I have read that you can configure pulse audio to use your second sound card as sorround or duplicate audio but the idea is dicrete audio from dicrete application. Is there such an use case already supported by pulseaudio?So there might be a solution if I disable Pulse Audio but I rather not but I'm open to either.

I have installed the latest version of aMSN (aMSN | Download aMSN software for free at SourceForge.net) which supports sending my webcam video. Unfortunately, it is unable to send my audio at the same time which is highly frustrating.
Does anyone know of a Linux equivalent of MSN which allows video and audio communication. I have tried Kopete, although the call feature button is inactive, despite having setup my webcam in this program.
I have also tried installing a program called qnext, though webcam and audio support between alternate different Instant Messengers (IM's) are not supported.

Strange one. Just upgraded my mother-in-law's computer from 8.04 to 10.04 via the update manager. All seems to be working beautifully except ...
* When I run gstreamer-properties and do an output test I get a test sound through the headphones plugged into the front audio socket of the machine using the 'Analogue Headphones' setting in Sound Preferences. (This rules out dead headphones.)
* When I try to play audio through any app I get no sound through the headphones, but if I change the setting to 'Analogue Output' in Sound Preferences I get audio loud and clear through the speakers which are plugged into the audio socket at the rear of the machine. how the gstreamer-properties test is getting audio to the front socket I guess I'd be getting somewhere.
