Comment (by JEEB):
Similar end result, but the last comments there are most probably off
regarding iTunes-specific metadata in MOV-derivatives in #2325 .
Libavcodec should nowadays be pushing out negative timestamps (which is
correct, and visible by the nonzero start time), but with output formats
that cannot handle negative timestamps either libavformat or ffmpeg cli
moves the first packet to position zero (at least that was the end of the
last technical discussion I had on this). That then leads to this effect
of all samples being output instead of just those having timestamps >=0.
