[ Latest version is v3.0.71 ]

• why can`t you be more cyclomatic like your brother?
• All ansi color codes striped when output is not a tty.
• threefive.Cue.xmlbin() now returns a threefive.xml.Node instance like threefive.Cue.xml().
• threefive.Stream has a new method threefive.Stream.rt(func=show_cue) that parses SCTE-35 and proxies the stream to stdout at realtime speed.

• Cli tool new features
  • __New bump keyword to adjust SCTE-35 PTS. Supports positive and negative adjustments.
  • New rt keyword parses SCTE-35, writes a SCTE-35 sidecar file, and outputs the MPEGTS stream to stdout at realtime speed.
  • All MPEGTS related tasks show parsing speed.

• Stream.decode_next() is now a generator

	from threefive import Stream

    strm =Stream(some_url)
    for cue in strm.decode_next():
		your_complicated_function(cue, one_arg , two_arg, 13,)

[Quick Start]

• Most of the stuff in threefive all works the same way.

[cli tool]

• The default action is to read a input and write a SCTE-35 output.

  • Inputs: mpegts, base64, hex, json,and xml, and xmlbin.

  • Outputs: base64, bytes, hex, int, json, xml, and xmlbin.

  • Sources: SCTE35 can read from strings, files, stdin, http(s), multicast,srt and udp.

Input	Output	How to use
mpegts	base64	threefive https://example.com/video.ts base64
base64	hex	threefive '/DAWAAAAAAAAAP/wBQb+AKmKxwAACzuu2Q==' hex
xmlbin	int	threefive < xmlbin.xml int
xml	json	threefive < xml.xml
mpegts	xml+bin	threefive video.ts xmlbin
json	xml	threefive < json.json xml

[ 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.

threefive 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.

  threefive < json.json  

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

[ threefive Streams Multicast, it's easy. ]

• The threefive cli has long been a Multicast Receiver( client )
• The cli now comes with a builtin Multicast Sender( server).
• Start the Receiver first
• It's optimized for MPEGTS (1316 byte 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.
• threefive cli also supports UDP Unicast Streaming.
