Hi, gstreamer-devel:     I have no idea what happened to you -- I tried on my Ubuntu and seems gst-plugins-ugly found my lame library. These are my steps:     1. sudo apt-get install lame liblame-dev     2. cd <gst-plugins-ugly-root-directory>     3. ./autogen --prefix=/usr     The output from configure is: ===================================== configure: *** checking feature: lame mp3 encoder library *** configure: *** for plug-ins: lame *** checking for lame_init in -lmp3lame... yes checking lame/lame.h usability... yes checking lame/lame.h presence... yes checking for lame/lame.h... yes configure: *** These plugins will be built: lame .................. configure: *** Plug-ins without external dependencies that will be built:     asfdemux     dvdlpcmdec     dvdsub     iec958     mpegaudioparse     mpegstream     realmedia configure: *** Plug-ins without external dependencies that will NOT be built:     synaesthesia configure: *** Plug-ins with dependencies that will be built:     amrnb     lame configure: *** Plug-ins with dependencies that will NOT be built:     a52dec     cdio     dvdnav     dvdreadsrc     id3tag     mad     mpeg2dec     sid Now type 'make' to compile gst-plugins-ugly. =====================================     So, maybe you should recheck your environment. Or does something wrong with your lame library?

The "libmp3lame.so" does exists after I install lame-398-2 , I could see it. I checked the " ./configure --help " , I found a option " -disable-lame ". My understanding is that lame is enabled by default . Could you please help me to check these infomation ? 2008/11/28, Eric Zhang <<a href="mailto:nicolas.m.zhang@gmail.com">nicolas.m.zhang@gmail.com</a>>: <div><div></div><div class="Wj3C7c">> Hi, gstreamer-devel: > >     1.
