Any idea _why_ they might be dropped?
The "drop=" statistics corresponds to frames that were dropped to
accommodate the output frame rate. With the segment muxer, ffmpeg
automatically selects CFR mode, and with your video, it guesses 14.99 as the
frame rate. If your input actually has more frames than that, they are
dropped.
Well, it has 15. At least, that is what it is set to. It is quicktime
broadcaster, and I have never read anywhere that its 15 FPS is actually 14.99,
so it should be the 15 that it claims.

and output, match the images together and see what happens to the
timestamps.
I'm not at the moment certain how to do that, but I will try to find a way. I
haven't been able to reproduce this when converting a .mov file to MPEGTS
segments, only when taking input from the network. But I am not sure that I
have tried it with a mov produced by the same software.
