     27 // allows error resilience tests, packet loss tests, etc.
     28 // Does not test the media optimization deirectly, but via the VCM API only.
     29 // The test allows two modes:
     30 // 1 - Standard, basic settings, one run
     31 // 2 - Release test - iterates over a number of video sequences, bit rates, packet loss values ,etc.
