# `threefive`


## `SCTE35 Decoder Ring` 
* `Parse SCTE 35 messages from Mpeg-ts files.` 
* `Parse SCTE 35 messages encoded in Base64 or Hex.`

### `New Feature`
#### threefive.SHOW_SPLICE_NULL

If you want to surpress displaying Splice Null commands: 

* `threefive.SHOW_SPLICE_NULL=False.`

Set it before doing anything else. 
Here's an example:
```go
 python
Python 3.7.4 (default, Jul 16 2019, 07:12:58) 
[GCC 9.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import threefive
>>> threefive.SHOW_SPLICE_NULL=False
>>> tf=threefive.parse_tsfile('/home/a/mpegwithscte35.ts')

```

### `Specification`
* https://www.scte.org/SCTEDocs/Standards/ANSI_SCTE%2035%202019r1.pdf

### `Splice Commands`
* `Splice Null`
* `Splice Schedule` (maybe)
* `Splice Insert`
* `Time Signal`
* `Bandwidth Reservation` (maybe)

### `Splice Descriptors`
* `DTMF Descriptor`
* `Segmentation Descriptor` (mostly)
  * `segmentation upid` (some)
  * `segmentation type and messages`
* `Time Descriptor` (maybe)
* `Audio Descriptor`

### `Dependencies`
* Python 3
* bitstring

## `Install`
```go
pip install threefive
