Detect multiple Simultaneous Live Streams on Youtube

I'm trying to find a way to detect multiple live simultaneous streams on a same youtube channels.

I want to avoid using the search from the API because of the cost (100) and used since now the "get methods" by using this url : https://www.youtube.com/channel/CHANNEL_ID/live.

But when there is multiple streams in the same time this url seems to redirect only to one of the live.

Does anybody have a magic trick for that ?

I'm using Python and made something like that :

def get_channel_live_url(p_channelID):    LiveChannelVideo = re.compile(r'https://www.youtube.com/watch\?v=(.*)')    urlpage = 'https://youtube.com/channel/'+p_channelID+'/live'    links = browse_and_return_balise(urlpage, balise='link', rel='canonical')    for link in links:        isLiveChannelVideo = LiveChannelVideo.search(link['href'])        if isLiveChannelVideo != None:            return isLiveChannelVideo.group(1)

where browse_and_return_balise are something like that :

def browse_and_return_balise(url, balise='a', class_=None, attrs=None, rel=None):   result = []   page = urllib.request.urlopen(url)   soup = BeautifulSoup(page, 'html.parser')   result = soup.find_all(balise, class_=class_, attrs=attrs, rel=rel)   # Collect all links   return result

The issue is that when a youtube channel broadcast 2 live at the same time I only catch the first one.
