Dear josiahg777,

Thanks for the quick reply! I am sorry, maybe I make you misunderstand. I just use OGG vorbis as one example ; ) My application is to develop one program with Gstreamer to play the real time camera video on one rtsp server. Just like the followed coding:
appdata->pipeline = gst_parse_launch ( "rtspsrc name=my_rtspsrc ! rtpmp4vdepay ! xviddec ! ffmpegcolorspace ! xvimagesink sync=0", &error );
But when I check my scratchbox armel and Nokia N810, it only installed gst-plugin-base & gst-plugin-good. Because xviddec plugin is in gst-plugin-bad (libgstxvid.so). Therefore, I need to install this xvid plugin in my scratchbox and N810. But when I install gst-plugins-bad, it only generate libgstxvid.a & libgstxvid.la (libgstxvid.so does not exist). I don`t know which descrepency lib is needed by libgstxvid, or I miss some steps of installation? Thanks!
