411Enhancing Simulation Environments with TRAFIL
When all the required parameters have been set, the simulation can be executed. If the simula-
tion has been successful, then the postsimulation parameters become available, namely, the sender
and receiver les, the .dat les, as well as the MP4 video traces. Thus, the user is able to select
various combinations of these les and retrieve QoS statistics for his or her video transmission. The
rst phase of the video simulation, the presimulation phase, is shown earlier in Figure 14.16. In this
phase, all the necessary parameters for the video encoding using FFmpeg must be dened.
Then using the MP4 ...
