This guide applies for the latest [Xuggle][1] release from [Github][2] (5.5).
|
|
<br />
|
|
<br />
|
|
|
|
It is useful if you want to compile **Xuggle** from source on the latest **Ubuntu** release (14.04). I have been compiling using a **64 bits** system.
|
|
<br />
|
|
|
|
You can find more complete information on the [dedicated page from the Xuggle website][3].
|
|
And if you need even more info, you can have a look at [the advanced build page][4].
|
|
<br />
|
|
<br />
|
|
First of all, we will need to install some packages needed during the compilation :
|
|
<br />
|
|
|
|
$ apt-get install ant git yasm # Installing various dependencies
|
|
$ apt-get install build-essential # g++, gcc and others
|
|
|
|
We then want to download and install the latest Java 7 realease
|
|
For that, we use a ppa.
|
|
|
|
$ add-apt-repository ppa:webupd8team/java
|
|
$ apt-get update && apt-get install oracle-java7-installer
|
|
|
|
Then, we can clone the latest Xuggle source code directly from github :
|
|
|
|
$ git clone https://github.com/artclarke/xuggle-xuggler.git
|
|
$ cd xuggle-xuggler
|
|
|
|
|
|
**We will also need to upgrade g++**. Indeed, if we don't do that the compilation will result in an error due to unauthorized type conversion.
|
|
The precise error message is :
|
|
|
|
([exec] ../../../../../../../csrc/com/xuggle/xuggler/Codec.cpp:158:38: error: converting 'false' to pointer type 'int (*)(AVCodecContext*, void*, int*, AVPacket*)' [-Werror=conversion-null])
|
|
|
|
To solve this, I configured **g++ < 4.8** to be used by default **(4.6 here)**
|
|
|
|
$ apt-get install g++-4.6
|
|
$ update-alternatives --remove-all g++
|
|
$ update-alternatives --display c++
|
|
$ update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.6 10
|
|
$ update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 20
|
|
|
|
$ update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++ 30
|
|
$ update-alternatives --set c++ /usr/bin/g++
|
|
$ update-alternatives --config g++ # Choose the older version
|
|
|
|
|
|
|
|
Finally, we can try to compile Xuggle from source.
|
|
|
|
$ ant stage
|
|
|
|
Compilation takes roughly **10 minutes** on my system.
|
|
<br />
|
|
<br />
|
|
If the compilation is successful, you can get the generated **jar** in the dist folder.
|
|
The latest release of Xuggle embeds the **so** files directly in the jar, so you shouldn't need anything else.
|
|
<br />
|
|
<br />
|
|
Compiling Xuggle from scratch in 14.04 has been surprisingly easy comparing to 12.04. The compilation scheme has been greatly improved in the latest Xuggle release.
|
|
<br />
|
|
<br />
|
|
**Note : Xuggle is now deprecated, and has not been updated for now almost a year. So far, I haven't found an equivalent that would be just as good. Let me know if you do!**
