That is true. SKIP_SAMPLES can not be reused, though, because it has SAMPLES
in it.

I am not sure what you mean here. Is it: if frames #42 #43 and #44 must be
skipped, set SKIP_FRAME=3 on packet #42 instead of FLAG=SKIP on all three
packets?

This case can already be handled by adjusting the timestamps on the packet,
unless I am mistaken.
