import os
import subprocessdef convert_ogg_to_mp3(directory):for filename in os.listdir(directory):if filename.endswith(".ogg"):# 获取文件的完整路径file_path = os.path.join(directory, filename)# 创建一个新的文件名，只是将扩展名从.ogg更改为.mp3new_filename = os.path.splitext(filename)[0] + ".mp3"new_file_path = os.path.join(directory, new_filename)# 使用ffmpeg命令行工具转换音频格式try:cmd = ["ffmpeg","-i", file_path,"-vn",  # 忽略视频流（如果有的话）"-acodec", "libmp3lame",  # 使用MP3编码器new_file_path]subprocess.run(cmd, check=True)# 删除原始ogg文件os.remove(file_path)except subprocess.CalledProcessError as e:print(f"Error converting {filename}: {e}")except Exception as e:print(f"An error occurred while processing {filename}: {e}")# 使用你的目录路径替换下面的'C://testqq//'
convert_ogg_to_mp3('C://testqq//')
