no
it averages timestamps over time, so small errors are ok.

max_pts_correction sets the upper limit of timestamp correction per frame,
in seconds. if you set it to 0, you disable this correction (see -mc 0),
but i don't recommend that. maybe set to something lower than default 0.01,
for example 0.001 (+-1ms/frame correction allowed)
