 Myself and several others spent five years developing threefive, 
 and then I got F2A'ed out of the github account.
 threefive3 is the next step.
  
 Welcome to the show.

The threefive3 SCTE-35 Cli Super Tool

and python3 library.

✅ SCTE-35 Parser ✅ SCTE-35 Encoder ✅ SCTE-35 HLS ✅ SCTE-35 Xml+binary ✅ SCTE-35 Cli ✅ SCTE-35 library

• Parses SCTE-35 from MPEGTS, HLS, XML+Binary, Base64, Bytes, Hex, Integers, or JSON.
• Encode SCTE-35 to Base64, Bytes, Hex, Int, JSON, or Xml+binary.
• Built-in network support for HTTP(S), UDP, and Multicast.
• Automatic AES decryption for HLS.
• All HLS SCTE-35 Tags are Supported.

Latest release is v3.0.35

Released Thursday April 3rd, 2025 4am EDT

Stay up to date, only the latest release is supported.

Checkout the Super Cool SCTE-35 Examples

MPEGTS streams can be parsed for SCTE-35 with three lines of code.

Cli

• SCTE-35 Cli Super Tool Encodes, Decodes, and Recodes. This is pretty cool, it does SCTE-35 seven different ways.
  • The cli tool comes with builtin documentation just type threefive3 help

HLS

• Advanced Parsing of SCTE-35 in HLS with threefive3 All HLS SCTE-35 tags, Sidecar Files, AAC ID3 Header Timestamps, SCTE-35 filters... Who loves you baby?

Classes

• Class Structure
• The python built in help is always the most up to date docs for the library.

The Cli tool

The cli tool installs automatically with pip or the Makefile.

• SCTE-35 Inputs
• SCTE-35 Outputs
• Parse MPEGTS streams for SCTE-35
• Parse SCTE-35 in hls
• Display MPEGTS iframes
• Display raw SCTE-35 packets from video streams
• Repair SCTE-35 streams changed to bin data by ffmpeg

Inputs

• Most inputs are auto-detected.
• stdin is auto selected and auto detected.
• SCTE-35 data is printed to stderr
• stdout is used when piping video
• mpegts can be specified by file name or URI.

threefive3 udp://@235.2.5.35:3535

• If a file comtains a SCTE-35 cue as a string( base64,hex,int,json,or xml+bin), redirect the file contents.

  threefive3 < json.json  

• quoted strings(( base64,hex,int,json or xml+bin), can be passed directly on the command line as well.

threefive3 '/DAWAAAAAAAAAP/wBQb+ztd7owAAdIbbmw=='

Outputs

• output type is determined by the key words base64, bytes, hex, int, json, and xmlbin.
• json is the default.
• Any input (except HLS,) can be returned as any output
  • examples Base64 to Hex etc...)

Stream Multicast with the threefive cli, it's easy.

• The threefive3 cli has long been a Multicast Receiver( client )
• The cli now comes with a builtin Multicast Sender( server).
• It's optimized for MPEGTS (1316 Datagrams) but you can send any video or file.
• The defaults will work in most situations, you don't even have to set the address.
• threefive3 cli also supports UDP Unicast Streaming.

usage: threefive3 mcast [-h] [-i INPUT] [-a ADDR] [-b BIND_ADDR] [-t TTL]

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT, --input INPUT
                        like "/home/a/vid.ts" or "udp://@235.35.3.5:3535" or
