###   The __decode__ Function


 *   src [decode.py](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/decode.py)   
 * __threefive.decode__ is an all purpose function to decode SCTE 35 messages from a file or string.

 ```python3
import threefive
```
 *   __MpegTS__

```python3
threefive.decode('/path/to/mpegwithscte35.ts') 
```
 * __MpegTS__ over __http and https__

 ```python3
threefive.decode('https://futzu.com/xaa.ts') 
```
* __Base64__

mesg='/DA4AAAAAAAA///wBQb+AAAAAAAiAiBDVUVJAAAAA3//AAApPWwDDEFCQ0QwMTIzNDU2SBAAAGgCL9A='
threefive.decode(mesg)
```
* __Hex String__

```python3
hexed = "0xFC301100000000000000FFFFFF0000004F253396"

```
* __Hex Values( New! )__ 
```python3
raw_hex = 0XFC301100000000000000FFFFFF0000004F253396

###  Cue Class

   *  src [cue.py](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/cue.py)
   *  The __threefive.Cue__ class decodes a SCTE35 binary, base64, or hex encoded string. 
   *  __threefive.Cue__ provides several methods to access the parsed data.

```python3
from threefive import Cue

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

cue = Cue(b64)
cue.decode()
```

* A decoded __Cue__ instance contains: 

     * **cue.info_section** 
       * 1 [threefive.**SpliceInfoSection()**](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/section.py)

     * **cue.command** 	 
       * 1 of these commands:

         *  [ threefive.**BandwidthReservation()** ](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/commands.py#L35)    
         *  [ threefive.**PrivateCommand()** ](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/commands.py#L47 )
         *  [ threefive.**SpliceInsert()** ](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/commands.py#L105)
         * [ threefive.**SpliceNull()** ](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/commands.py#L63) 
         *  [ threefive.**TimeSignal()** ](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/commands.py#L76)


     * **cue.descriptors**  
        * a list of 0 or more of these descriptors :   

          * [ threefive.**AudioDescriptor()** ](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/descriptors.py#L48)  
          * [ threefive.**AvailDescriptor()** ](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/descriptors.py#L80)  
          * [ threefive.**DtmfDescriptor()** ](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/descriptors.py#L94)  
          * [ threefive.**SegmentationDescriptor()** ](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/descriptors.py#L137)  
          * [threefive.**TimeDescriptor()**](https://github.com/futzu/SCTE35-threefive/blob/master/threefive/descriptors.py#L115)

     *  __crc__

     * 'When parsing SCTE35 Cues from MPEGTS streams, 
       threefive attempts to include as many of the 
       following as possible.'   	
       *  __pid__ of the packet  
       *  __program__ of the pid 
       *  __pts__ of the packet 
       *  __pcr__ of the packet 
___


* All instance vars can be accessed via dot notation.

```python3
>>>> from threefive import Cue
>>>> cue = Cue(b64)
>>>> cue.decode()
True
>>>> cue.command
{'command_length': 5, 'command_type': 6, 'name': 'Time Signal', 'time_specified_flag': True, 'pts_time': 22798.906911}
>>>> cue.command.pts_time
22798.906911
>>>> 
```

* call one or more of these methods after decode.

|Cue Method                  | Description                                    |
|----------------------------|------------------------------------------------|
| cue.**get()**              | returns **cue as a dict**                      |
| cue.**get_json()**         | returns **cue as a JSON** string               |
| cue.**show()**             | prints **cue as JSON**                         |
|                            |                                                |

###  __Stream__ Class

 ```python3
  threefive.Stream(tsdata, show_null = False)
  ```

  * src [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.
  * Supports 
  	* __Multiple Programs__.
  	* __Multiple SCTE35 Streams__.
  	* __Multi-Packet PAT, PMT, and SCTE35 tables__. 
  	* __Constant Data Parsing__.
  	     * threefive.Stream is designed to __run continuously__ 

Method                              | Description
------------------------------------| -------------------------------------
[Stream.__show__()](#streamshow)                 |__Prints__ Streams that will be checked for SCTE35 
 [Stream.__decode__(func=show_cue)](#streamdecodefuncshow_cue)                                                                             | __Prints__ SCTE-35 __cues__ for SCTE-35 packets. Accepts an optional function, func, as arg.
[Stream.__decode_next__()](#streamdecode_next)|__Returns__ the next SCTE35 cue as a threefive.Cue instance. 
[Stream.__decode_program__(the_program=None, func=show_cue)](#streamdecode_programthe_program-func--show_cue) |Same as Stream.__decode__ except only packets where program == __the_program__
[Stream.__decode_proxy__(func=show_cue)](#streamdecode_proxyfunc--show_cue)      |Same as Stream.__decode__ except raw packets are written to stdout for piping to another program.


#### Stream.show()

 *  List programs and streams that will be checked for SCTE35 data.

```python3
>>>> from threefive import Stream, version
>>>> version()
'2.2.69'
>>>> with open('video.ts','rb') as tsdata:
....     strm = Stream(tsdata)
....     strm.show()
....     

Program:1030
        PID: 1034(0x40a) Type: 0x6
        PID: 1035(0x40b) Type: 0x86 SCTE35

Program:1100
        PID: 1104(0x450) Type: 0x6
        PID: 1105(0x451) Type: 0x86 SCTE35

Program:1080
        PID: 1084(0x43c) Type: 0x6

```
___


#### Stream.decode(func=show_cue)

 ```python3
 import sys
 from threefive import Stream

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

```

  *   Pass in custom function 

  *  __func__ should match the interface 
  ``` func(cue)```


```python3
import sys
import threefive

def display(cue):
   print(f'\033[92m{cue.packet_data}\033[00m')
   print(f'{cue.command.name}')

def do():
   with open(sys.argv[1],'rb') as tsdata:
    sp = threefive.Stream(tsdata)
    sp.decode(func = display)       

if __name__ == '__main__':
    do()
```
___


#### Stream.decode_next()

* Stream.decode_next returns the next SCTE35 cue as a threefive.Cue instance.

```python3
import sys
import threefive

def do():
    arg = sys.argv[1]
    with open(arg,'rb') as tsdata:
        st = threefive.Stream(tsdata)
        while True:
            cue = st.decode_next()
            if not cue:
                return False
            if cue:
                cue.show()

if __name__ == "__main__":
    do()
```
___


#### Stream.decode_program(the_program, func = show_cue)

* Use Stream.__decode_program()__ instead of Stream.__decode()__ 
to decode SCTE-35 from packets where program == __the_program__

```python3
import threefive

with open('../35.ts','rb') as tsdata:
    threefive.Stream(tsdata).decode_program(1)
```
___


#### Stream.decode_proxy(func = show_cue)

*  Writes all packets to __sys.stdout__.

*  Writes scte35 data to __sys.stderr__.

```python3

import threefive

with open('vid.ts','rb') as tsdata:
    sp = threefive.Stream(tsdata)
    sp.proxy_decode()
```

* Pipe to __mplayer__
```bash
$ python3 proxy.py | mplayer -
```
