WebRTC Translator
=================

Tiny daemon that translates between our protobuf protocol and the HTTP/JSON
protocol that lingjingle's peerconnection_client and peerconnection_server 
examples use.

Intended to live on the SVMP VM instance listening on localhost for connections
from the peerconnection_client-based version of fbstreamer. On the other side
the proxy connects to the input event server. HTTP/JSON messages from fbstreamer
are translated to protobuf and forwarded to the input server.

Building
========

Prerequisites:
*  Oracle JDK 6 (make sure `JAVA_HOME` is set properly)
*  ant
*  Protocol Buffers 2.5.0

Build Steps:
1.  Download the Protocol Buffers distribution and unpack it to a directory we'll call `PROTOBUF_DIR`
2.  Compile and install the protoc compiler, then add it to your PATH.
        cd $PROTOBUF_DIR
        ./configure
        make install
3.  Prepare the protocol buffer java runtime
        cd $PROTOBUF_DIR/java
        protoc --java_out=src/main/java -I../src ../src/google/protobuf/descriptor.proto
4.  Checkout the SVMP protocol to a directory of your choice we'll call `SVMP_PROTO`
        git clone https://github.com/SVMP/svmp-protocol-def.git $SVMP_PROTO
5.  Checkout the translator code to a directory we'll call `SVMP_WEBRTC_PROXY`
        git clone https://github.com/SVMP/android_external_svmp_webrtchelper.git $SVMP_PROXY
6.  Generate the SVMP protocol source and link in the protobuf runtime
        ln -s $PROTOBUF_DIR/java/src/main/java/com $SVMP_PROXY/src/com
        protoc -I $SVMP_PROTO --java_out=$SVMP_WEBRTC_PROXY/src $SVMP_PROTO/svmp.proto
8.  Build using ant. For example:
        cd $SVMP_WEBRTC_PROXY
        ant

If the protocol definition file is changed, re-run the protoc command in step 6 and recompile.
