python：pymedia安装

"Pymedia is a Python library for accessing and manipulating media files. It makes audio and video playback/creation a snap for even a newcomer to programming." There is a deb installer available for pymedia 1.3.5 but not for 1.3.7 So I decided to write this howto.

First install all the dependencies:


sudo apt-get install python-dev libogg-dev libvorbis-dev liblame-dev libfaad2-dev libasound2-dev python-pygame
        (Pygame is not really necessary, but recommended.)

Extract a download of pymedia-*.tgz and open a terminal in the extracted folder, so we can build pymedia:
python setup.py build
       
This should display:
Using UNIX configuration...
       
        OGG : found
        VORBIS : found
        FAAD : found
        MP3LAME : found
        VORBISENC : found
        ALSA : found
        Continue building pymedia ? [Y,n]:
       
If everything is found press Y

Finally install pymedia:
sudo python setup.py install
       

Test if pymedia installed correctly by typing this at the python shell:
import pymedia
       
        ==================
       
        Recently, I needed to use pymedia, for some audio and video encoding. The problem though, is that pymedia was nowhere to be found in the Ubuntu Hardy Heron package repository, and the only .deb installation candidate from the pymedia website was for an older version of pymedia and Python 2.4. Not wanting to run an old version and having Python 2.5 as a requirement, I needed to compile the package myself–no easy task, it turns out.
       
        Step 1. Get pymedia
       
        wget http://internap.dl.sourceforge.net/sourceforge/pymedia/pymedia-1.3.7.3.tar.gz
        tar xzvf pymedia-1.3.7.3.tar.gz
        cd pymedia-*
        Step 2: Get the pymedia dependencies (as noted here).
       
        sudo apt-get install python-dev libogg-dev libvorbis-dev liblame-dev libfaad-dev libasound2-dev python-pygame
        Step 3. Get GCC 3.4 (pymedia will not compile with GCC 4.0)
       
        sudo apt-get install gcc-3.4 g++-3.4
        export CC=gcc-3.4
        Step 4. Build/compile pymedia
       
        python setup.py build
        Step 5. Be a good Ubuntu user with checkinstall
        Checkinstall is great because it installs the package as a .deb file.
       
        sudo apt-get install checkinstall
        sudo checkinstall python setup.py install
        Note: If you want to be a bad Ubuntu user, you can run “sudo python setup.py install” instead of the checkinstall command.
       
        Step 6. Try it out
       
        python
        >>> import pymedia
