Download chats from past broadcast

notebook.ipynb has examples of statistics functions.

from twitch_chat_analyzer import analyzer

# Create an analyzer object from video ID.
# Video ID is the last part of the video URL (1234567890 in https://www.twitch.tv/videos/1234567890)
# If the chat log was not downloaded before, it will download automatically and create an analyzer.
ann = analyzer.FromVideoId('REPLACE_HERE_TO_VIDEO_ID')

# Some pre-built statistics functions to draw graph
ann.DrawChatPerMinute(10)  # Chat counts for each N-minute interval
ann.DrawTopChatters(20)  # Top N viewers with most chats
ann.DrawTopEmotes(15)  # Top N most used emotes

# If you just want to get the data
ann.GetChatPerMinute(10)  # Chat counts for each 10-minute interval, list of (offset, count)
ann.GetTopChatters()  # Viewer names and chat counts, list of (name, chat_count), sorted by chat count
ann.GetEmoteCounts()  # Emotes and usage counts, list of (emote_name, count), sorted by count

# If you want to handle dataframe yourself
df = ann.ToDataFrame()

# Some useful functions to deal with dataframe
df[df['is_sub_notice']]  # Show new/renew subscription notice messages
df[df['bits'] > 0]  # Show messages with bits
df['text_body'].apply(len).mean()  # Average chat length (excluding emotes)
