 Behaviour changes depending on how much of the provided file is read
 before the reception error, the following command starts encoding shortly
 before the issue above but also shows the remaining 40 seconds of the
 input stream:
 {{{
 $ ffmpeg -skip_initial_bytes 70000000 -vsync cfr -i input_with_error.h264
 -qscale 2 out.avi
