// media optimization test
// This test simulates a complete encode-decode cycle via the RTP module.
// allows error resilience tests, packet loss tests, etc.
// Does not test the media optimization deirectly, but via the VCM API only.
// The test allows two modes:
// 1 - Standard, basic settings, one run
// 2 - Release test - iterates over a number of video sequences, bit rates, packet loss values ,etc.
