And to answer Olivier, that file is busted indeed. Over chunks of 3-5 packets
it only increases the timestamp by 1-3ms ... and then syncs to the expected
timestamp (give or take a millisecond).

Once you:
* Only set timestamps on valid buffers (ones where the difference with the
previous one is greater than a certain margin (1-4ms)
* Set CLOCK_TIME_NONE on the invalid buffers (ones where the difference with
the previous one is less than a certain margin (1-4ms)

Then you end up with a resulting stream that jitters by less than a
millisecond.

I have no idea how that file was created but it was definitely created by a
broken software, ergo => broken file.
