I am trying to play video in browser. I use 'embed' tag in HTML.
The problem is, i am trying with a browser in linux, but i dont have the plugin installed in the browser(firefox). When i click ' install missing plugins', it says error saying unable to install.
Is it because mpeg file can't be played in linux? Please help
No, it is because there isn't a suitable plugin in the browser's database of known plugins. I believe VideoLan Client has a plugin that could cope with it.
If you want to do video on the web, then you are generally best off either simply going down the Flash route, or providing the video in WebM and h.264 and using the <video> element (usually with Flash as a backup for older versions of IE). This has the added benefit of being much more bandwidth efficient than MPEG 1 video.
There are two options, mplayer or xine... I prefer mplayer.. go to
http://www.mplayerhq.hu/homepage/design6/dload.html and download one of the source files...
To install:
1)go to your CLI (Command Line Interface) which should be konsole, xterm or something like that
2)go to the directory using this syntax | cd | cd .. (goto previous directory) and use the command ls to view whats in your current directory.
3)type tar -zxvf "filename"
4)it will create a folder, cd into that folder
5)type ./configure
6)type make
7)type su and enter password for r00t
8)type make install
now in the command line, there should be a command mplayer, have fun!

I had downloaded sublime previously directly from the browser as tarball and saved it in a folder (and of course extracted it).But this way I wasn't able to make Sublime my default editor and it didn't feature as an application when I tried to open a text file with a right-click.I read somewhere installing sublime text 3 using commands:
sudo add-apt-repository ppa:webupd8team/sublime-text-3
sudo apt-get update
sudo apt-get install sublime-text-installer
will solve my problem. So I directly deleted the Sublime_text3 folder saved in my Downloads directory and then used the given commands. But when I entered the 3rd command line I got the following error(just writing the error part):
subprocess new pre-installation script returned error exit status 1
Errors were encountered while processing:/var/cache/apt/archives/sublime-text-installer_3126-2~webupd8~1_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
Can anyone explain why this error is coming and suggest a way to solve this problem? Also if anyone can tell how I can set Sublime as my default text editor from the tarball downloaded from the sublime text 3 website. Thanks in advance!
you can try this command to install Sublime Text using Snap Store..
sudo snap install sublime-text --classic
I'm not sure overall how to fix that error or what's going on (I use Slackware and not Ubuntu/Debian), but for a long while there have been official Sublime repositories several different Linux distributions, including Ubuntu/Debian.
It's highly recommended that you use those if you want to go the package route and not use existing solutions such as the one referenced in your question or in the other response here, if for no other reason than only the official repository is guaranteed to contain an unmodified version of Sublime. Additionally the official repositories are always updated on release, which may or may not happen in a timely manner in other repositories.
The links referenced above contain instructions on how to set up and use Sublime from those repositories, and if you have any issues a good place to ask is the forum.
One thing to note which isn't mentioned explicitly in the above pages is that to use the official repositories, you should:
Choose only one of them (stable or dev, noting that you need a license to run a dev version) and not add both repositories or things will not work as expected
Ensure that other repositories that you've added (such as the one in your question) are removed to make sure that the package system definitely pulls the correct package
There are a couple of ways to go if you want to install Sublime from the tarball version. The easiest way would be to extract it, then manually set up launcher shortcuts and so on based on what falls out. How exactly you would register it as a text editor in that case, I'm not entirely sure since I don't use the same distribution as you.
Presuming that the process would be easier if Sublime was installed in a way similar to how the package manager would do it, the tarball comes with a desktop file and icons, so the following steps can be used to (presumably) do what the package installer would do.
The proviso here is that although these steps work on my non-Ubuntu machine, I don't know if all of the referenced tools are installed by default on an Ubuntu system, so so more setup work may be involved.
Note also that the files in the tarball are not entirely self-consistent, which makes this a little bit more work.
First, you need to extract the tarball (replace tarball filename as appropriate for location and build):
cd /opt
sudo tar xvf ~/Downloads/sublime_text_3_build_3176_x64.tar.bz2
This creates the folder /opt/sublime_text_3/ and fills it with the contents of the tarball.
Next, you want to install the icons contained in the tarball. As far as I have been able to tell, the icons in the tarball aren't in the correct directory structure, requiring each to be copied into place individually. We also need to update the icon cache to ensure that the new icon is noticed by the system:
cd /usr/share/icons/hicolor/
sudo cp /opt/sublime_text_3/Icon/16x16/sublime-text.png 16x16/apps/
sudo cp /opt/sublime_text_3/Icon/32x32/sublime-text.png 32x32/apps/
sudo cp /opt/sublime_text_3/Icon/48x48/sublime-text.png 48x48/apps/
sudo cp /opt/sublime_text_3/Icon/128x128/sublime-text.png 128x128/apps/
sudo cp /opt/sublime_text_3/Icon/256x256/sublime-text.png 256x256/apps/
sudo gtk-update-icon-cache -f -t .
Now we want to install the sublime_text.desktop file that is in the tarball. Note however that like the icons, it seems kind of broken; the tarball extracts to sublime_text_3 but the desktop file assumes that the application is actually in /opt/sublime_text instead.
As such, you either need to rename the folder that was extracted to sublime_text to match what is in the desktop file, or edit the desktop file to make the path correct.
The following steps assume that we want to keep the folder the same and rewrite the desktop file. These commands will generate a new file named sublime_text_3.desktop with the changes.
cd /opt/sublime_text_3/
sed -e "s^/sublime_text/^/sublime_text_3/^" sublime_text.desktop | sudo tee sublime_text_3.desktop
Now you can install the desktop file. You do that with desktop-file-install, passing it the name of the desktop file. For accessing Sublime from the command line, you also want to set up a subl link to the installed copy of Sublime.
Adjust the paths as appropriate here if you decided to rename the folder instead of editing the desktop file:
sudo desktop-file-install sublime_text_3.desktop --rebuild-mime-info-cache
sudo ln -s /opt/sublime_text_3/sublime_text /usr/bin/subl
At this point Sublime should show up as an installed application, or at least it does in my Window Manager; if not, executing sudo update-desktop-database may help refresh it.
You can try this once. i hope it will help
wget https://download.sublimetext.com/files/sublime-text_build-4126_amd64.deb
sudo dpkg -i sublime-text_build-4126_amd64.deb
I am trying to install eclipse in a linux box via terminal using below command but it doesn't work.
wget "http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/luna/SR2/eclipse-jee-luna-SR2-linux-gtk-x86_64.tar.gz&mirror_id=454"
When it gets downloaded, I see this file name which is wrong?
download.php?file=%2Ftechnology%2Fepp%2Fdownloads%2Frelease%2Fluna%2FSR2%2Feclipse-jee-luna-SR2-linux-gtk-x86_64.tar.gz
Instead it should be - eclipse-jee-luna-SR2-linux-gtk-x86_64.tar.gz What's wrong?
I renamed the file to correct name and tried untarring it but I get an error as shown below:
tar -xvzf eclipse-jee-luna-SR2-linux-gtk-x86_64.tar.gz
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
What's wrong?
Using wget for eclipse Java
command is :
wget http://www.mirrorservice.org/sites/download.eclipse.org/eclipseMirror/technology/epp/downloads/release/2022-03/202203101200/eclipse-java-2022-03-R-linux-gtk-aarch64.tar.gz
You can change the release of eclipse in the URI. See this link for more information. I hope that's useful for you.
Any URL which includes download.php will have this problem with wget, even the so called "Direct Link".
With more recent download pages however, there is a way to find the actual URLs, and that's to look inside the xml file that download.php uses for mirror selection.
For example, if we go to the Eclipse IDE 2020-03 page, most of the URLs are download.php links, but in the "Other options for this file" side bar, we can see an xml link.
If we navigate there with our web browser and then look at the page source, we can see the actual file URL used by every mirror. Depending on the Web Browser used, the page may be blank, in which case we need to look at the Page Source to see the raw xml and thus the URLs.
For me, in the UK, the UK mirror service site would be my best option:
<mirror url="http://www.mirrorservice.org/sites/download.eclipse.org/eclipseMirror/oomph/epp/2020-03/R/eclipse-inst-win64.exe" label="[United Kingdom] UK Mirror Service (http)" />
These (actually) direct URLs do work with wget.
Looks like issue with the download link form eclipse website itself.
Please try with the below URL (I have tested it in Ubuntu 14 and its working)
http://eclipse.stu.edu.tw/technology/epp/downloads/release/luna/SR2/eclipse-jee-luna-SR2-linux-gtk.tar.gz
Using a Debian variant?
sudo apt-get install eclipse
Otherwise, I think you just copied the link from the main Eclipse download page, which is a link to another page which grabs the fastest mirror for the download of the file.
For example, the link it gave me is this, which downloads fine
http://mirror.cc.columbia.edu/pub/software/eclipse/technology/epp/downloads/release/luna/SR2/eclipse-jee-luna-SR2-linux-gtk-x86_64.tar.gz
After that, the answer is mostly contained on AskUbuntu: How to install Eclipse?
If you're Using Ubuntu 20.04.4 LTS
$ wget file-link
Downloaded file might look like this :- download.php?file=%2Foomph%2Fepp%2F2022-06%2FR%2Feclipse-inst-jre-linux64.tar.gz
Execute following command:
1.First Move to download directory.
2.Execute tar -xvf eclipse-inst-jre-linux64.tar.gz
3.Move to Dir - cd eclipse-installer
4. Execute ./eclipse-inst. It will ask you which dev mode you want to install please select and click next.
Once installed successfully you will get can see launch icon.
Use a console version of oomph installer:
Download Console Oomph Installer, choose the appropriate download for your target platform (zip or tar.gz), example for Linux:
wget -O installer.tar.gz https://search.maven.org/remotecontent?filepath=com/github/a-langer/org.eclipse.oomph.console.product/1.0.1/org.eclipse.oomph.console.product-1.0.1-linux.gtk.x86_64.tar.gz
Extract archive and change current directory:
tar -xvzf installer.tar.gz
cd eclipse-installer/
Install "Eclipse IDE for Java Developers":
./eclipse-inst -nosplash -application org.eclipse.oomph.console.application -vmargs \
-Doomph.installation.location="$PWD/ide" \
-Doomph.product.id="epp.package.java"
Wait for the installation to complete, last version of Eclipse will be installed in "$PWD/ide".

I have download and extracted 64 bit install_flash_player_11_linux.x86_64.tar.gz Adobe Flash Player via a ssh session (wget command). Now the package states that "Copy the libflashplayer.so file to the plugins folder of your browser."
It states that default it should be /usr/lib/firefox/plugins, but:
# ls -l /usr/lib/firefox/plugins
ls: cannot access /usr/lib/firefox/plugins: No such file or directory
I would be an using a X Windows Client for same - so where should I copy /opt/libflashplayer.so shared library?
To give an insight I am installing Weave - the app would actually run on a browser on a client box expect that deployment is completely done in Linux box - so is it that I need to install /opt/libflashplayer.so
It looks to me like the plugin directory might actually be at
/usr/lib/mozilla/plugins
However, I would maybe recommend installing it to the home plugins folder at
~/.mozilla/plugins

I hope to pack the nodejs(includes its installed module via npm) and javascript code to one execute file for different plateform(windows, osx, linux).
Is it possible or any solution?
Your comment welcome
From my understanding, you can't really create an executable file for multiplatforms. Each platform has it's own packaging format to make it binary executable. What you can do is to create a x.tar.gz file and expand it to your target platform. I myself haven't done it but theoretically it's possible. Here is an example (assuming you're using GNU tar for all your platforms):
To pack it, do:
tar cvzf nodeproject.tar.gz nodeproject
To expand, do
tar xvzf nodeproject.tar.gz
I want to access video file information (specifically, the video horizontal and vertical dimensions) in the Bash terminal of Scientific Linux on a system over which I do not have root privileges. The setup is conservative and does not feature the modern utilities, such as exiftool and avprobe, that would be used to do this. What would be a way of accessing this information using standard Unix utilities or some other means likely to work on a conservative Linux setup? To be specific, I am looking for something such as the following:
<utility> video1.mp4
1280x720
Thanks for any ideas!
How to build and run typical open source software from source without root
Even if you don't have root, provided that:
you can at least use the compiler and related tools
you can download source code
you don't need too many strange libraries
then download the source code for your tool of choice and install it into $HOME/opt/somedir.
For example, for avprobe you could probably download the last stable source release, then build it like this:
tar xzf libav.....gz
cd libav.....
./configure --prefix=$HOME/opt/libav
make
make install
then run it as
$HOME/opt/libav/bin/avprobe
You may or may not need to tweak the value of LD_LIBRARY_PATH or various other things.
