§ 5 · Push/Pull URLs

5.1 URL Format

推流地址：rtmp://push.livestream.com/live/{StreamName}?签名参数
拉流地址：
  - RTMP: rtmp://play.livestream.com/live/{StreamName}
  - HLS: http://play.livestream.com/live/{StreamName}.m3u8

import time

def generate_push_url(app_key, stream_name, domain):
    # 计算过期时间（当前时间+6小时）
    expire = int(time.time()) + 21600

    # 生成签名
    plain = f"{app_key}{stream_name}{expire}"
    sign = hashlib.sha1(plain.encode()).hexdigest()

    return f"rtmp://{domain}/live/{stream_name}?expire={expire}&sign={sign}"

• Graceful degradation for non-critical issues
• Timeout handling: 30s default, 300s max
