A note about Rec Splitter timestamps and offsets

The rec_splitter tool requires timestamps to be specified in microsecond. Which is something to keep in mind when splitting recordings with an offset (in seconds).

Let's say you a rec file beginning with something like this :

Launched at 10:29:08.327 (09/07/2020)
[STDB v2.0]
Offset (sec) : 1579251897
[Data]

As you can see there is an offset of 1579251897 (seconds) in the recorded data. To use the splitter, you will need to take this offset value and add 6 following zero to convert that offset defined in seconds to microseconds.

So in order to split the first 10 seconds you will need to specify the following interval

1579251897000000;1579251907000000

And to split from the 4th second to the 8th, that interval becomes:

1579251900000000;1579251940000000

If you need to split several interval, simply add them to a csv file, here called timestampsInterval.csv (make sure each interval is separated with a new-line character) and feed that file to the rec_splitter using :

rtmaps_rec_splitter --timestamps timestampsInterval.csv -i myRecordings.rec
