The way backward playback is implemented doesn't break basic assumptions
about timestamps after the decoder, so I guess all the encoding mode
needs to do is to adjust for the start offset, which it already does.
Though I might be wrong and my test was possibly flawed.
Stream recording on the other hand will fail immediately with
--record-file, and --stream-record will probably yield unexpected
results if any backstep seeks are done.
