I entirely agree with this. Libavformat should export what is stored in
the file as accurately as possible. It does not have enough information
about the context/use case to fix timestamps, nor whether fixing is even
required.

We can and eventually should provide optional code for timestamps
generation/manipulation, e.g. in the form of a bitstream filter which
would have access to accurate reordering information. But it should be
entirely separate from the demuxer.
