We rotuinely generate clips from recorded streams and seem to run into weird behavior of -ss and -t. also it seems the hls stream always has a start-time of 1.4s. This is not the core problem though. when we generate short clips deep in to the stream i.e. -t 1000 -s 10 it often happens we get no output at all.

or to compress that last mail:
the hls has a start offset of 1.4 (even though the transcoding source does not).
when clipping a 1s segment from 0 the output start offset is 0
when clipping a 1s segment from 1 the output start offset is 0.6
when clipping a 1s segment from 2 the output start offset is 0.6
