<P><FONT SIZE=2>As you tall me, using the libvlc_playlist_add_extended function I can set the width, height and video position. </FONT>
</P>
<P><FONT SIZE=2>Thank you very much and thanks for all the people helped me.</FONT>

</P>
<P><FONT SIZE=2>It's actually a vocabulary problem. You can call libvlc_new() twice, but</FONT>
<BR><FONT SIZE=2>some stuff behind will be shared. Most notably, the configuration will</FONT>
<BR><FONT SIZE=2>be shared, that's why you can't use global options to handle</FONT>
<BR><FONT SIZE=2>positionning.</FONT>
</P>
<P><FONT SIZE=2>For example, if you consider the following snippet: </FONT>
</P>
<P><FONT SIZE=2> libvlc_instance_t *p_instance, *p_instance2;</FONT>
<BR><FONT SIZE=2> char *argv[] = { "vlc", "-vvv","--no-color" };</FONT>
<BR><FONT SIZE=2> char *argv1[] = { "vlc", "-vvv","--color" };</FONT>
</P>
<P><FONT SIZE=2> libvlc_exception_t exception;</FONT>
<BR><FONT SIZE=2> libvlc_exception_init( &exception );</FONT>
</P>
<P><FONT SIZE=2> fprintf( stderr, "********* INIT 1\n" );</FONT>
<BR><FONT SIZE=2> p_instance = libvlc_new( 3, argv, &exception );</FONT>
<BR><FONT SIZE=2> fprintf( stderr, "********* INIT 2\n" );</FONT>
<BR><FONT SIZE=2> p_instance2 = libvlc_new( 3, argv1, &exception );</FONT>
<BR><FONT SIZE=2> fprintf( stderr, "********* Add\n" );</FONT>
<BR><FONT SIZE=2> libvlc_playlist_add( p_instance, "test.mp3" , NULL , &exception );</FONT>
<BR><FONT SIZE=2> fprintf( stderr, "************ Playing : %i %i\n", libvlc_playlist_isplaying( p_instance, &exception ), libvlc_playlist_isplaying( p_instance2, &exception ) );</FONT></P>
<P><FONT SIZE=2> fprintf( stderr, "********** Play\n" );</FONT>
<BR><FONT SIZE=2> libvlc_playlist_play( p_instance, -1, 0, NULL, &exception );</FONT>
<BR><FONT SIZE=2> sleep( 1 );</FONT>
<BR><FONT SIZE=2> fprintf( stderr, "************ Playing : %i %i\n", libvlc_playlist_isplaying( p_instance, &exception ), libvlc_playlist_isplaying( p_instance2, &exception ) );</FONT></P>
<P><FONT SIZE=2> sleep( 1 );</FONT>
<BR><FONT SIZE=2> fprintf( stderr, "********** Kill\n" );</FONT>
<BR><FONT SIZE=2> libvlc_destroy( p_instance );</FONT>
<BR><FONT SIZE=2> libvlc_destroy( p_instance2 );</FONT>
</P>
<P><FONT SIZE=2>You will correctly see that two instances are created, and that only one</FONT>
<BR><FONT SIZE=2>plays the test.mp3 file (You'll see Playing : 1 0) ... but all messages</FONT>
<BR><FONT SIZE=2>will be black-and-white.</FONT>
</P>
<P><FONT SIZE=2>What you can do is use so-called input options to the specific items.</FONT>
</P>
<P><FONT SIZE=2>For that, use the libvlc_playlist_add_extended call, which takes</FONT>
<BR><FONT SIZE=2>an array of strings as argument. Use a syntax like "video-x=12"</FONT>
<BR><FONT SIZE=2>"video-y=42" in this array.</FONT>
