Stuttering rendering using ffmpeg and sdl2
22 décembre 2020, par Wiesen_WalleWith the following Code I get a stuttering rendering of the movie file. Interesstingly, when dumping information with ffmpeg it says it has 25 fps and a duration of 00:01:32.90 ; however when counting the frames and time it runs by myself it gives a time of about 252 seconds, I guess the code receiving the frames and sending the package (int cap(vid v)) draws the same frame multiple of times. But I cannot see what's wrong ?


//PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/:/usr/lib64/pkgconfig/ --> add path to PKF_Config search path

How to take screenshots of streamers using the Twitch API
10 décembre 2020, par oo92My goal is to create a dataset of gameplays on Twitch using the API. How I want to do it is this :


- 

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

client = TwitchClient(client_id='<my client="client">')
streams = client.streams.get_live_streams(limit=100)

print(streams)
</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
ffmpegto 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 :
