adbreak2 Generates SCTE-35 Cues for Sidecar files.

a@fu:~$ ./adbreak2 -h
usage: adbreak2 [-h] [-d DURATION] [-e EVENT_ID] [-i] [-o] [-p PTS]
                [-s SIDECAR] [-v]

options:
  -h, --help            show this help message and exit
  -d DURATION, --duration DURATION
                        set duration of ad break. [ default: 60.0 ]
  -e EVENT_ID, --event-id EVENT_ID
                        set event id for ad break. [ default: 1 ]
  -i, --cue-in-only     only make a cue-in SCTE-35 cue [ default: False ]
  -o, --cue-out-only    only make a cue-out SCTE-35 cue [ default: False ]
  -p PTS, --pts PTS     set start pts for ad break. Not setting pts will
                        generate a Splice Immediate CUE-OUT. [ default: 0.0 ]
  -s SIDECAR, --sidecar SIDECAR
                        Sidecar file of SCTE-35 (pts,cue) pairs. [ default:
                        sidecar.txt ]
  -v, --version         Show version

Install

1. git clone https://github.com/futzu/adbreak2
2. python3 -mpip install threefive
3. cd adbreak2
4. install adbrerak2 /usr/local/bin

Use

• Running adbreak2 with no args will generate a Splice Insert Cue, with Splice Immediate and Out of Network set. A CUE_OUT.
• The Cue data is displayed, and the base64 SCTE-35 string is written to sidecar.txt.
