Want to include vlc in your Qt application?

Qt and VLC

Well, we have a very easy howto for you: libVLC in Qt .

This will output the video inside the widget that you want using QWidget::winId() method.

This has been tested on Linux and Windows, using libVLC 0.9.9.

Need

If you can't build your application easily, remember to install libvlc-dev or to use the SDK for windows from the .zip files of the releases!

Participate

Don't hesitate to complete this!

VLC and IDE

Jean-Baptiste Kempf — Thu, 30 Apr 2009 08:19:00 +0200

I receive many questions about using an IDE to build VLC.

Usually, the answer is VIM. But I will try to introduce something else today.

Needs

Yeah, VIM is TEH awesome, but sometimes we would like more. But usually, more is slow, incomplete and boring...

Would you want an editor with:

VIM syntax and command,
Completion that is faster than the one from Eclipse
Git inclusion
Doesn't eat all your RAM
Debuggueur and step-by-step+breakpoints integration like MSVC?

I guess so!

Believe it or not, there is a solution: QtCreator from Nokia/QtSoftware that I have tested to work with VLC.

Even if you don't think this will be useful for you, at least read in diagonale the following post.

Installation

Take QtCreator 1.1 (don't take older versions, they won't fit for VLC, or the VIM part will suck...)

   `apt-get install qtcreator` in Debian/Sid

Take Qt4.5.1 (I mean it, Qt 4.5.0 is buggy!)

Setup

General Setup

Run QtCreator and launch Tools->options
- Activate FakeVim and set ShiftWidth to 4
- Text Editor->Behaviour, set Tab size at 4
- Text Editor->Display, enable Text Wrapping and display right margin, and if you like Alexis' vim, Visualize whitespace
- Text Editor, change the colour schemes to match you old editor

Save options.

VLC Setup

For the example, I assume that you build your vlc in a "build" subdir of the source (as xtophe usually gives advice)

 * File->New
   Select 'Import of Makefile-based Project'
   -
   Project Name 'VLC'
   Location '/home/you/vlc' and Choose, Next
   -
   Let it process... It should take around 1minute
   Finish.

EXIT QtCreator... I MEAN it.

Setup Indexation

QtCreator will have done VLC.includes VLC.creator, VLC.files and a VLC.config in your vlc/ folder.

Overwrite the VLC.includes and the VLC.files with the one you can find:

Doing this will gain you some time. Those could be auto-generated one day, I guess...

Setup Build

Relaunch QtCreator

Select Projects (on the left) and select VLC on the list
Build Settings,
- Change Build directory to /home/you/vlc/build, using browse
Run Settings,
- Add a custom Executable with the blue '+'
- Name it VLC, browse to /home/you/vlc/build/vlc for Executable
- Put -Iqt in Arguments
Click on Edit on the left. You should see VLC with most useful files.

Build VLC and launch it.

In the Menu, Build and Build All, you should see the Compilation output on the bottom (or by clicking on the left build progressbar)
In the same menu, Build and Run it, and VLC will launch directly, outputting everything in the Application output.

Cool. But that was just a minimum...

Using it like VIM: Good!

Open modules/codec/avcodec/audio.c from the file browser and see... You are using VIM commands to control. You have Visual, Edit and all usual VIM modes!

Completion is triggered with Ctrl+Space and will give you a list. If there is no ambiguition, it is filled.
. and -> triggers the list of the members of the struct or the class by default.
After function completions, it will give the type of the arguments.

F2 will give you access to the function definition where your mouse is.

Debugging it: awesome!

You can put breakpoints in the margins near the line numbers. (Like in modules/gui/qt4/main_interface.cpp:100 and 108)

Now re run it using debug running.

It will stop at your breakpoint and you will have the function call lists (and line numbers) but also pointers values (like p_intf, and this in main_interface.cpp)

You can, of course Step In, Step Into and Step Out, resume or stop the code

More coolness:

Locate

Use the locate search box to find quick declarations: 'm vlc_object_act' will help you to go quickly to the method declaration, etc...

Git

Use the Git menu to checkout from within QtCreator.

Nota Bene

The indexing shouldn't be too long, but could be a bit longer the first time you launch the project!

Have fun!

Howto build VLC 1.0.0-git in Ubuntu in less than 5 commands.

Jean-Baptiste Kempf — Tue, 03 Mar 2009 13:38:00 -0800

Since building VLC is easier and easier now, I am compelled to improve my HOWTOS. Here is one for Ubuntu, that can easily adapt to Debian.

This is not a complete and detailed post, but just a summary. If you need more details, take the Build on Intrepid HOWTO.

Get all you need

sudo apt-get build-dep vlc && sudo apt-get install libtool build-essential automake1.10 git-core

Get the source

git clone git://git.videolan.org/vlc.git

Go

cd vlc && ./bootstrap

mkdir build && cd build && ../configure --disable-nls --enable-qt4

make

Done.

Build VLC media player under Ubuntu Intrepid

This post is an update of the popular howto for Build VLC with feisty and Build VLC with hardy.

Those articles are always popular on my blog, so here is an update.

This post is an update of the popular howto for Build VLC with feisty and Build VLC with hardy.

Those articles are always popular on my blog, so here is an update.

Introduction

So we are going to build the latest VLC possible.

Everything will be done in a console/terminal and should be straight-forward. Every question should be asked on the forum, or in the comments here.

Conventions

Every line beginning with a # should be done as root, or using the sudo command. Every line beginning witha % is a normal line.

Building VLC

Prepare your environment

We need a few package starting from a fresh intrepid:

# apt-get install vlc
# apt-get build-dep vlc 
# apt-get install cvs build-essential git git-core automake1.9 libtool
# apt-get install libcddb2-dev libzvbi-dev yasm

Checkout VLC trunk and bootstrap the tree

% git clone git://git.videolan.org/vlc.git

% cd vlc
% ./bootstrap

Build x264

x264

x264 is a library to encode movies in H.264.

% cd extras/
%
% git clone git://git.videolan.org/x264.git
% cd x264
% make
% sudo make install
% cd ../..

Configure VLC

Configure

 
% mkdir build; cd build;
%../configure --prefix=/usr --enable-mozilla

Finish

% make

You just have to wait a bit :D

VLC: misc and builds

Jean-Baptiste Kempf — Mon, 04 Feb 2008 20:02:00 +0100

Just some miscellaneous news about VLC and build systems:

Tree Cleaning: we decided to clean the tree of all the not really necessaries folder that are around now. See the wiki.

There is some experiments to build VLC using CMake inside the main tree. Checkout the latest VLC to test it.

Windows nightly builds are back after the big changes in the building and in the config.h changes.

New contribs with updated 3rd party libraries are done for windows.

Windows CE and Symbian port are advancing... Not yet released, and ETA is really unknown.

Roadmap are changing, more about that soon.

Configure-step in VLC building.

Jean-Baptiste Kempf — Fri, 14 Dec 2007 21:09:00 +0100

Idea

VLC can be built with a classical process: ./bootstrap; ./configure --options; make

However, since VLC is very modular, not everyone wants the same modules built so the configure line can be very long.

Therefore, I'll try to explain a bit the main configure options and give a few examples.

Configure

./configure

Build vlc under a fresh sid

Jean-Baptiste Kempf — Thu, 04 Oct 2007 13:39:00 +0200

Introduction

So we are going to build the latest VLC possible.

I already did it for ubuntu feisty and it had a huge success. I am going to do the same for debian/sid, which is the distro I use in normal time.

However, some steps did changed, and I compile more options here, because I can :D

Everything will be done in a console/terminal and should be straight-forward. Every question should be asked on the forum, or in the comments here.

Conventions

Every line beginning with a # should be done as root, or using the sudo command. Every line beginning witha % is a normal line.

Building VLC

Prepare your environment

# apt-get build-dep vlc
# apt-get install build-essential subversion tofrodos
# apt-get install portaudio-dev

Checkout it

% svn co svn://jb@svn.videolan.org/vlc/trunk vlc-trunk
% cd vlc-trunk;

Bootstrap it

% ./bootstrap

It has to finish with: Successfully bootstrapped

live

Live is a streaming library. you'll need it to read some streams.
