The initial-segment-number option allows for passing in the number for the first
segment. This is useful if you want to append to an existing live
stream.

Use the revision just before libspeexdsp split

Using lowest PTS or DTS is a bad idea, as lower video packets are sent
ahead of pts, and most audio tracks are sending packets near to pts.
So we had audio packets coming late, with a lower pts, and corrupted
our PCR as we take the lowest pts among tracks.
We can't also guess the full tracks rolls, so updating after a full
roll instead of each packet is useless.
Send time is a reliable base time.

Offsets pts & duration

Reads keyframe flag from payload extensions.
Some formats like DVR-MS ships keyframe info into
payload extensions and not as packet flag. Why make things simple ?

already microseconds

Sub-Payloads must have their pts computed from deltapts.

Use pts as track time, and then for pcr.
