• How to take screenshots of streamers using the Twitch API

  10 décembre 2020, par oo92

  My goal is to create a dataset of gameplays on Twitch using the API. How I want to do it is this :

  


  

  1. Get a list of live streams using the API.

  


  2. Use streamlink and ffmpeg on Python to take the screenshots through the Stream source

  


  


  To get the streams, I have the following code thanks to a SO user :

  


  from twitch import TwitchClient&#xA;&#xA;client = TwitchClient(client_id=&#x27;<my client="client">&#x27;)&#xA;streams = client.streams.get_live_streams(limit=100)&#xA;&#xA;print(streams)&#xA;</my>

  


  The output is this. Its a lot larger, I just made it shorter... :

  


  [{'id': 40889579422, 'game': 'Among Us', 'broadcast_platform': 'live', 'community_id': '', 'community_ids': [], 'viewers': 74594, 'video_height': 1080, 'average_fps': 60, 'delay': 0, 'created_at': datetime.datetime(2020, 12, 9, 23, 53, 34), 'is_playlist': False, 'stream_type': 'live', 'preview': {'small': 'https://static-cdn.jtvnw.net/previews-ttv/live_user_sykkuno-80x45.jpg', 'medium': 'https://static-cdn.jtvnw.net/previews-ttv/live_user_sykkuno-320x180.jpg', 'large': 'https://static-cdn.jtvnw.net/previews-ttv/live_user_sykkuno-640x360.jpg', 'template': 'https://static-cdn.jtvnw.net/previews-ttv/live_user_sykkuno-{width}x{height}.jpg'}, 'channel': {'mature': False, 'status': 'amongus at 4 !!', 'broadcaster_language': 'en', 'broadcaster_software': '', 'display_name': 'Sykkuno', 'game': 'Among Us', 'language': 'en', 'id': 26154978, 'name': 'sykkuno', 'created_at': datetime.datetime(2011, 11, 15, 1, 29, 29, 140794), 'updated_at': datetime.datetime(2020, 12, 10, 0, 35, 50, 916363), 'partner': True, 'logo': 'https://static-cdn.jtvnw.net/jtv_user_pictures/sykkuno-profile_image-6ab1e70e07e29e9b-300x300.jpeg', 'video_banner': 'https://static-cdn.jtvnw.net/jtv_user_pictures/4b654ce5-58dc-4fa6-b77c-7250bb2d5269-channel_offline_image-1920x1080.png', 'profile_banner': 'https://static-cdn.jtvnw.net/jtv_user_pictures/1caee146-3323-4d45-9907-96c20c224d3e-profile_banner-480.png', 'profile_banner_background_color': '', 'url': 'https://www.twitch.tv/sykkuno', 'views': 23590965, 'followers': 1928724, 'broadcaster_type': '', 'description': 'Hi ! ', 'private_video': False, 'privacy_options_enabled': False}}, ... 


  


  First, I want to know how I can iterate through the JSON to get the channel name using the id. I tried to do it on my own but it said that it isn't subscriptable.

  


  Second, I have the following code that tries to use ffmpeg to get a screenshot of the stream through its source :

  


  import streamlink, os

# This code connects to the streamer's source
# Get the Twitch API to work so you can add the streamer's name at the end of the link
username = 'Sykkuno'
streams = streamlink.streams('http://twitch.tv/' + username)

# Stream source
stream = streams["best"].url

# Directory where the screenshots will be saved
dir_path = os.getcwd() + '/' + username

# number of streamers
streamers = 1

os.system('ffmpeg -i ' + stream +' -r 0.5 -f image2 ${dir}/output_%09d.jpg')


  


  But that is throwing the following error :

• ffmpeg takes screenshots all at once

  19 décembre 2020, par oo92

  I am trying to use ffmpeg to grab screenshots of twitch streams. This is my command :

  


  ffmpeg -i https://stream-link.m3u8 
-ss 30 
-frames:v 10 
-r 1
-f 
image2 
/home/me/Desktop/images/image-dataset/my-dataset/World-of-Warcraft/filename.jpg&


  


  My goal is to take 1 screenshot per second for a total of 10 screenshots. I've added the & at the end of the filename.jpg to take these screenshots concurrently. However, the screenshots I get are all the same thing. No difference. The exact spitting moment in all 10 images. My take is that ffmpeg is not listening to -frames:v 10 and instead takes 10 screenshots all at once.

  


  I tried to run it sequentially and the same problem happened. So the issue isn't concurrency..

  


  Is there a way I can fix this ?

• Adaptive part in MPD using MP4box

  28 janvier 2019, par enigmaVada

  I have used ffmpeg to encode audio and video files of my video sample.mp4 for the dash player. The commands are as follows :

  ffmpeg -i sample.mp4 -s 426x240 -c:v libx264 -b:v 640k -g 90 -an sample_video_240.mp4
  
  ffmpeg -i sample.mp4 -s 480x360 -c:v libx264 -b:v 960k -g 90 -an sample_video_360.mp4
  
  ffmpeg -i sample.mp4 -s 640x480 -c:v libx264 -b:v 1280k -g 90 -an sample_video_480.mp4
  
  ffmpeg -i sample.mp4 -s 1280x720 -c:v libx264 -b:v 2560k -g 90 -an sample_video_720.mp4
  
  
  
  ffmpeg -i sample.mp4 -c:a aac -b:a 128k -vn sample_audio.mp4

  I have generated 240p,360p,480p and 720p videos and audio file.

  Then I have used mp4box to generate the mpd file using the following command :

  mp4box -dash 10000 -rap -profile dashavc264:onDemand -mpd-title BBB -out sample.mpd -frag 5000 sample_audio.mp4 sample_video_240.mp4 sample_video_360.mp4 sample_video_480.mp4 sample_video_720.mp4 

  I am using the dash.js player to play the video. The problem is, the adaptive part of DASH isn’t working. The player is just using the 240p video and not switching to a better format even if proper bandwidth is available. I am checking using the network tab of chrome dev tools.

  What am i doing wrong ? Please help.

  Here is the mpd file for reference :
