# A simple RTP server
#
# Transcodes and streams audio and video to H263p and AMR respectively from any
# file that is decodable by decodebin.
#
# use ./client-H263p-AMR.sh to receive the RTP stream.
#
# change these to change the server sync. This causes the server to send the
# packets largly out-of-sync, the client should use the RTCP SR packets to
# restore proper lip-sync between the streams.
