# pyVBAN
python implementation of the VBAN (VB Audio network) protocol
Specification here: https://www.vb-audio.com/Voicemeeter/VBANProtocol_Specifications.pdf
The module supports audio receiving and transmitting + text transmitting

## Requierments
Need of the pyaudio module
Python implementation of the VBAN (VB Audio network) protocol

## pyVBAN.VBAN_Recv() usage:
```python
cl = VBAN_Recv("IP-FROM","StreamName",Port,OutputDeviceIndex,verbose=False)
cl.runforever()
```
Original specifications here: https://www.vb-audio.com/Voicemeeter/VBANProtocol_Specifications.pdf

Example:
```python
cl = VBAN_Recv("127.0.0.1","Stream7",6981,10,verbose=False)
cl.runforever()
```
or
Supported sub-protocols:
- [x] Audio
- [x] Serial **(To verify)**
- [x] Text
- [ ] Service

As I'm currently not using VBAN nor VB-Audio products I have no plans to implement this further.
I will do my best to maintain it!

For any feature request, the specs are open, feel free to open a PR 😀

## Using the built-in utilities
### List devices
```bash
$ python -m pyvban.utils.device_list
```
```python
cl = VBAN_Recv("127.0.0.1","Stream7",6981,10,verbose=False)
while True:
cl.runonce()
import logging
import pyvban
logging.basicConfig(level=logging.DEBUG)
pyvban.utils.device_list()
```

## pyVBAN.VBAN_Send() usage:
### Receiver
```bash
$ python -m pyvban.utils.receiver --address 127.0.0.1 --port 6980 --stream Stream1 --device 11
```
```python
cl = VBAN_Send("IP-TO",PORT,"StreamName",SampleRate,DeviceInId,verbose=False)
cl.runforever()
import logging
import pyvban
logging.basicConfig(level=logging.DEBUG)
receiver = pyvban.utils.VBAN_Receiver(
sender_ip="127.0.0.1",
stream_name="Stream1",
port=6980,
device_index=11
)
receiver.run()
```

Example:
### Sender
```bash
$ python -m pyvban.utils.sender --address 127.0.0.1 --port 6980 --stream Stream1 --rate 48000 --channels 2 --device 1
```
```python
cl = VBAN_Send("127.0.0.1",6980,"Stream8",48000,3,verbose=True)
cl.runforever()
import logging
import pyvban
logging.basicConfig(level=logging.DEBUG)
sender = pyvban.utils.VBAN_Sender(
receiver_ip="127.0.0.1",
receiver_port=6980,
stream_name="Stream1",
sample_rate=48000,
channels=2,
device_index=1
)
sender.run()
```
or

### Send text
```bash
$ python -m pyvban.utils.send_text --address 127.0.0.1 --port 6980 --stream Command1 "Strip[5].Mute = 0"
```
```python
cl = VBAN_Send("127.0.0.1",6980,"Stream8",48000,3,verbose=True)
import logging
import pyvban
import time
logging.basicConfig(level=logging.DEBUG)
send_text = pyvban.utils.VBAN_SendText(
receiver_ip="127.0.0.1",
receiver_port=6980,
stream_name="Command1"
)
state = False
while True:
cl.runonce()
state = not state
if state:
send_text.send("Strip[5].Mute = 0")
else:
send_text.send("Strip[5].Mute = 1")
time.sleep(1)
```

## pyVBAN.VBAN_SendText() usage:
```python
cl = VBAN_SendText("IP-TO",PORT,BAUDRATE,"StreamName")
cl.send("Command")
```

Example:
## Craft a packet manually

```python
cl = VBAN_SendText("127.0.0.1",6980,9600,"Command1")
cl.send("Strip[0].Gain = -6")
```
import pyvban

## Help
To find the output device index you can use this code:
pcm_data = b"" # 128 sample stereo data
header = pyvban.VBANAudioHeader(
sample_rate=pyvban.subprotocols.audio.VBANSampleRates.RATE_48000,
samples_per_frame=128,
channels=2,
format=pyvban.subprotocols.audio.VBANBitResolution.VBAN_BITFMT_16_INT,
codec=pyvban.subprotocols.audio.VBANCodec.VBAN_CODEC_PCM,
stream_name="Stream1",
frame_counter=0,
)

```python
import pyaudio
p = pyaudio.PyAudio()
info = p.get_host_api_info_by_index(0)
numdevices = info.get('deviceCount')

print("--- INPUT DEVICES ---")
for i in range(0, numdevices):
if (p.get_device_info_by_host_api_device_index(0, i).get('maxInputChannels')) > 0:
print("Input Device id ", i, " - ", p.get_device_info_by_host_api_device_index(0, i).get('name'))

print("--- OUTPUT DEVICES ---")
for i in range(0, numdevices):
if (p.get_device_info_by_host_api_device_index(0, i).get('maxOutputChannels')) > 0:
print("Input Device id ", i, " - ", p.get_device_info_by_host_api_device_index(0, i).get('name'))
vban_packet = header.to_bytes() + pcm_data
vban_packet = vban_packet[:pyvban.const.VBAN_PROTOCOL_MAX_SIZE]
```

## Parse a packet manually
```python
import pyvban

def run_once(self):
data, addr = socket.recvfrom(pyvban.const.VBAN_PROTOCOL_MAX_SIZE)
packet = pyvban.VBANPacket(data)
if packet.header:
if packet.header.sub_protocol != pyvban.const.VBANProtocols.VBAN_PROTOCOL_AUDIO:
print(f"Received non audio packet {packet}")
return
if packet.header.stream_name != self._stream_name:
print(f"Unexpected stream name \"{packet.header.stream_name}\" != \"{self._stream_name}\"")
return
if addr[0] != self._sender_ip:
print(f"Unexpected sender \"{addr[0]}\" != \"{self._sender_ip}\"")
return
```
