+# externremux.sh - sample remux script using mencoder for remuxing.
+#
+# Install this script as VDRCONFDIR/plugins/streamdev-server/externremux.sh
+#
+# The parameter QUALITY selects the default remux parameters. Adjust
+# to your needs and point your web browser to http://servername:3000/ext/
+# To select different remux parameters on the fly, insert a semicolon
+# followed by the name and value of the requested parameter, e.g:
+#   e.g. http://servername:3000/ext;QUALITY=WLAN11;VBR=512/
+# The following parameters are recognized:
+#
+# PROG   actual remux program
+# VC     video codec
+# VBR    video bitrate (kbit)
+# VOPTS  custom video options
+# WIDTH  scale video to width
+# AC     audio codec
+# ABR    audio bitrate (kbit)
+# AOPTS  custom audio options
+#
