I was able to troubleshoot the code to the point of getting verbose=true to output to console, however no sound is being transmitted.

Hi there! Awesome project! 🎉

I've been poking around, and found a few ways that I think I could help offer some enhancements. Are you open to contributions?

Hello,

I failed to send multiple streams, either to two separate devices or to one, even with different ports.
I then tried with Python Process but the result is the same.
I also cannot use send and receive at the same time.
Here is my code:

import pyVBAN
from multiprocessing import Process

def send(ip, port, streamName, sampleRate, deviceId):
    vbanSendSlot = pyVBAN.VBAN_Send(ip, port, streamName, sampleRate, deviceId, verbose=False)
    vbanSendSlot.runforever()

def recv(ip, port, streamName, deviceId):
    vbanRecvSlot = pyVBAN.VBAN_Recv(ip, streamName, port, deviceId, verbose=True)
    vbanRecvSlot.runforever()

def startSend1():
    sendSlot1 = Process(target=send, args=("10.0.254.6", 6980, "Stream1", 48000, 12))
    sendSlot1.start()
    sendSlot1.join()

def startSend2():
    sendSlot2 = Process(target=send, args=("10.0.254.6", 6981, "Stream2", 44100, 12))
    sendSlot2.start()
    sendSlot2.join()

def startRecv1():
    recvSlot1 = Process(target=recv, args=("10.0.254.6", 6980, "RECV", 14))
    recvSlot1.start()
    recvSlot1.join()


if __name__ == '__main__':
    startSend1()
    startSend2()
    startRecv1()

Is this normal or is there a specific setting to be made?

Sorry if my English is not very good, I use Google Translate.

Hi, I was playing around with this and I found the following problems:

• When I run VBAN_Recv(), it yields the following error: struct.error: unpack requires a buffer of 8 bytes on the line self.stream_frameCounter = struct.unpack("l",data[24:28])[0]. I just tried to replace the line with self.stream_frameCounter = struct.unpack("l",data[24:32])[0] and it works fine. Not sure why this 8 bytes constraint was not the case on your system...

• When I run VBAN_Send(), it keeps yielding the following error [Errno 56] Socket is already connected. I tried to change the PORT number, assuming socket refers to that, without success.

Any idea of why that might be?

VBAN_Send runs for a while then quits with the following message:-
src/hostapi/alsa/pa_linux_alsa.c:3641: PaAlsaStreamComponent_BeginPolling: Assertion 'ret == self->nfds' failed

I have tried different sample rates but no change and the time before aborting varies.
Looking at htop the system (Intel© Core™ i3-3110M CPU @ 2.40GHz × 2 Linux Mint 20.1 Cinnamon) is not stressed, process taking about 5% CPU and total CPU load ~30%.

VBAN_Recv runs without stopping.

Hi, I just got around to trying out pyVBAN, and your updates could not have been better timed.

However, the README may still need to be updated for Python 3, specifically the print statements in the PyAudio script to list devices.

Thanks!

I was curious if you had preferences on the license for this project? Others in the same space have seemed to have gone with either the GPL 3.0 or Apache 2.0, and I was wondering if you had any thoughts on this?
