Help on module threefive.encode in threefive:

NAME
    threefive.encode - encode.py

DESCRIPTION
    threefive.encode has helper functions for Cue encoding.

FUNCTIONS
    mk_splice_insert(event_id, pts=None, duration=None, out=False)
        mk_cue returns a Cue with a Splice Insert.

        The args set the SpliceInsert vars.

        splice_event_id = event_id

        if pts is None (default):
            splice_immediate_flag      True
            time_specified_flag        False

        if pts:
            splice_immediate_flag      False
            time_specified_flag        True
            pts_time                   pts

        If duration is None (default)
            duration_flag              False

        if duration IS set:
            out_of_network_indicator   True
            duration_flag              True
            break_auto_return          True
            break_duration             duration
            pts_time                   pts

        if out is True:
            out_of_network_indicator   True

        if out is False (default):
            out_of_network_indicator   False

    mk_splice_null()
        mk_splice_null returns a Cue
        with a Splice Null

    mk_time_signal(pts=None)
         mk_time_signal returns a Cue
         with a Time Signal
        if pts is None:
             time_specified_flag   False

        if pts IS set:
             time_specified_flag   True
             pts_time              pts

|  __init__(self, tsdata, show_null=True)
|
|      tsdata is a file or http, https,
|       udp or multicast url.
|
|      set show_null=False to exclude Splice Nulls

|  decode(self, func=show_cue)
|      Stream.decode reads self.tsdata to find SCTE35 packets.
|      func can be set to a custom function that accepts
|      a threefive.Cue instance as it's only argument.
