## ```Advanced threefive```

###  ```Splice Class```  
   *  source [splice.py](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/splice.py)

   *  The __threefive.Splice__ class decodes a SCTE35 binary, base64, or hex encoded string. 
   *  __threefive.Splice__ provides several methods to access the parsed data.

```python

from threefive import Splice

b64 = "/DBIAAAAAAAA///wBQb+ek2ItgAyAhdDVUVJSAAAGH+fCAgAAAAALMvDRBEAAAIXQ1VFSUgAABl/nwgIAAAAACyk26AQAACZcuND"

scte35 = Splice(b64)

````
#### ```Pretty Print SCTE 35 Message```
```python
scte35.show()
```

#### ```Return SCTE 35 Message```
```python
scte35.get()
```

#### ```Pretty Print Splice Info Section```
```python
scte35.show_info_section()
```

#### ```Return Splice Info Section```
```python
scte35.get_info_section()

```        
#### ```Pretty print Splice Command```
```python
scte35.show_command()

{ 'name': 'Time Signal',
  'pts_time': 22798.906911,
  'time_specified_flag': True}

```

#### ```Return Splice Command```
```python
scte35.get_command()

``` 

#### ```Pretty Print Splice Descriptors```
```python
scte35.show_descriptors()

```    
#### ```Return Splice Descriptors```
```python
scte35.get_descriptors()

```

###  ```Stream Class``` 
  * source [stream.py](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/stream.py)

  * The __threefive.Stream__ class parses SCTE35 messages from a file or stream.

```python3
  threefive.Stream(tsdata, show_null = False)
  ```
   * __tsdata__ is an open file handle or sys.stdin.buffer to read 'piped' in data.
   * __show_null__ if set to True, enables showing SCTE 35 null commands.

 #### ```Parse a Local File with a Stream Instance```

 ```python3

 import sys
 from threefive import Stream
 '''

 if __name__ =='__main__':
    with open(sys.argv[1],'rb') as tsdata:
        Stream(tsdata)

```

#### ```Pipe a Video to Stream```

```sh

###  ```StreamPlus Class``` 
  * source [streamplus.py](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/streamplus.py)
  * __threefive.StreamPlus__ is a sub class of  __threefive.Stream__

```python3
  threefive.StreamPlus(tsdata, show_null = False)
```
   * __tsdata__ is an open file handle or sys.stdin.buffer to read 'piped' in data.
   * __show_null__ if set to True, enables showing SCTE 35 null commands.

   * __threefive.StreamPlus__ adds the PID and PTS timestamp for each SCTE 35 packet.
