audio2face 有两种驱动方式

nvidia ace模式，docker服务器

2.live link模式，audio2face2023 为代表。

ue 5.1python 接口实时驱动：

/World/audio2face/Player

audio2face 用的

SimpleUDPTCPSocketClient 通讯

角色蓝图里面 socket client init udp receiver

127.0.0.1 5008

绑定事件到 on receiver

版本：audio2face-2023.2.0

audio2face 新增 audio player，选择stream audio player.

可以播放，不能驱动

python 复制代码

import subprocess
import os

# 注意：请替换为你的Audio2Face实际安装路径
A2F_SCRIPTS_DIR = r"D:\pro_2026\audio2face-2023.2.0\exts\omni.audio2face.player\omni\audio2face\player\scripts\streaming_server/"


def stream_audio_to_a2f(wav_file_path):
    """
    向正在运行的Audio2Face Streaming Player发送音频文件
    """
    # 切换到流服务器脚本目录
    os.chdir(A2F_SCRIPTS_DIR)

    # 构建命令：使用test_client.py发送音频
    # 假设你的Streaming Player在USD场景中的路径是 /World/StreamingPlayer
    command = f"python test_client.py {wav_file_path} /World/audio2face/StreamingPlayer"
    # command = f"python test_client.py {wav_file_path} /omni.audio2face.player.Player"
    command = f"python test_client.py {wav_file_path} /World/audio2face/Player"
    command = f"python test_client.py {wav_file_path} /World/audio2face/PlayerStreaming"

    try:
        subprocess.run(command, shell=True, check=True)
        print(f"成功发送音频: {wav_file_path}")
    except subprocess.CalledProcessError as e:
        print(f"发送失败，命令执行错误: {e}")
    except FileNotFoundError:
        print("错误：未找到test_client.py脚本，请检查A2F_SCRIPTS_DIR路径。")


# 使用示例
stream_audio_to_a2f(r"D:\data\audios\post_0.wav")

可以驱动，待测试
