I have a program which has a lot of music decks (deck 1, deck 2, music_clip_deck, speackers_deck, ip_call_1, ip_call_2, ip_call_3). Each deck works in a seperate process. The chunk time I use to crop the mp3 files/retransmitions stream/voice from microphone/voice from aiortc-pyav is 125msec. After that I fill some queues (one for each seperate process) and I send the final queue to the final thread for the final audio processing before hearing and transmitted to clients.
How can I synchronize all the process together, so one while run time of each process takes exactly 125 msec?
Here is one figure for help:
This approach may not help at all:
class Deck_1_Proc(Process):......... def run(self): while(True): t1 = time.time() ... ... ... t2 = time.time() if t2 - t1 < 0.125: time.sleep(0.125 - (t2 - t1))Maybe a better approach should be use something like javascript setInterval with time parameter: 125msec
from threading import Event, Threaddef call_repeatedly(interval, func, *args): stopped = Event() def loop(): while not stopped.wait(interval): # the first call is in `interval` secs func(*args) Thread(target=loop).start() return stopped.set#call:cancel_future_calls = call_repeatedly(0.125, run)#stopping to app termination:cancel_future_calls()
