Title: Use Python to connect with the Tencent Cloud interface to implement the video live broadcast function

Abstract: This article will introduce how to use the Python programming language to connect with the Tencent Cloud interface to implement the video live broadcast function. Through the SDK and API provided by Tencent Cloud, we can quickly implement live streaming and playback functions. This article will use specific code examples to introduce in detail how to use Python for live streaming and playback operations.

1. Preparation work

Before we start writing code, we need to do some preparation work.

1. Register a Tencent Cloud account and activate the live broadcast service. After registering a Tencent Cloud account, activate the live broadcast service in the Tencent Cloud console to obtain information such as application ID, key, push domain name, and playback domain name.
2. Install the Python environment and dependent libraries. Python is a simple and easy-to-learn programming language that can be downloaded and installed on the official website (https://www.python.org/). After the installation is complete, you can use the pip command to install related dependent libraries.

pip install qcloudlive-python-sdk

2. Implementation of push function

Next, we will implement the push function of live video. Push streaming is to transmit the video stream to Tencent Cloud so that it can be watched by the audience.

1. Import dependent libraries and set parameters

At the beginning of the Python code, we need to import the qcloudlive-python-sdk library and set relevant parameters, such as application ID and key , push domain name, etc.

from qcloudlive import QCloudLive
from qcloudlive import PusherConfig

app_id = "your_app_id"  # 替换为真实的应用ID
secret_id = "your_secret_id"  # 替换为真实的密钥ID
secret_key = "your_secret_key"  # 替换为真实的密钥

pusher_config = PusherConfig()
pusher_config.app_id = app_id
pusher_config.secret_id = secret_id
pusher_config.secret_key = secret_key
pusher_config.push_domain = "your_push_domain"  # 替换为真实的推流域名

2. Create a push instance and start pushing

Next, we need to create a push instance and use the start_push method to start pushing.

qcloud_live = QCloudLive(pusher_config)

stream_id = "stream1"  # 推流流ID，自定义命名
push_url = qcloud_live.create_push_url(stream_id)
qcloud_live.start_push(stream_id)

# 可在控制台输出推流地址，供观众观看
print("Push URL: ", push_url)

3. Implementation of playback function

In addition to the push function, we also need to implement the playback function of live video. Playback is to obtain the pushed video stream from Tencent Cloud and play it on the viewer end.

1. Import dependent libraries and set parameters

Different from the push function, the playback function requires the use of different configuration classes and methods. We need to import the PlayerConfig class and play method, and set relevant parameters.

from qcloudlive import PlayerConfig

player_config = PlayerConfig()
player_config.app_id = app_id
player_config.secret_id = secret_id
player_config.secret_key = secret_key
player_config.play_domain = "your_play_domain"  # 替换为真实的播放域名

2. Create a play instance and start playing

Next, we need to create a play instance and use the play method to start playing.

qcloud_live = QCloudLive(player_config)

stream_id = "stream1"  # 推流流ID，与推流时保持一致
play_url = qcloud_live.create_play_url(stream_id)
qcloud_live.play(stream_id)

# 可在控制台输出播放地址，供观众观看
print("Play URL: ", play_url)

Conclusion

Through the introduction of this article, we have learned how to use Python to connect with the Tencent Cloud interface to implement the video live broadcast function. Through the SDK and API provided by Tencent Cloud, we can quickly implement live streaming and playback functions. This article gives detailed code examples, hoping to be helpful to readers in their actual development work.
