[vlc-devel] problems using libvlc.

[ChengYQ]

Hi,
 
When I run the original installed vlc, all modules works fine, but when I use libvlc,and try to put
arguments ":sout=#transcode{vdev=mp4v......." and run it, the system said that "there are no modules
matched the transcode", I think maybe because of the options when I compile/link it.I used:export VLC_SRC=/tmp/vlc-0.8.6cgcc -I ${VLC_SRC}/include/ -lvlc -L ${VLC_SRC}/src/.libs/ demo.c -o demoHow can I specify a typical location of the transcode? Should this be done when link or through passing arguments to libvlc_new?thanks a lot!
