Comment 21 for bug 82307

Gstreamer comes with a plugin, cdxaparse, that parses a .dat file from (S)VCD into raw MPEG-1.

Reference: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-plugins/html/gst-plugins-bad-plugins-plugin-cdxaparse.html

Do gst-inspect-0.10 | grep -i vcd
to check if you have the plugin.
