STREAM_GET_POSITION/LENGTH are still in bytes. But DEMUX_GET_* now try
to use the PCR to have real values, and the seeks in the demuxer
are based on PCR.
The issue comes probably from the fact that now the TS demuxer does 10
seek at the start. Dunno how the http live streaming copes with it.
I will deactivates this mode when the stream_t layer report slow seek
