我要评论将aac转为mp3,保持原有目录结构
需要提前安装ffmpeg
import os
import subprocess
import time
from concurrent.futures import threadpoolexecutor, as_completed
def convert_file(input_path, output_path):
command = [
'ffmpeg',
'-y', # 自动覆盖现有文件
'-i', input_path,
'-acodec', 'libmp3lame',
'-b:a', '192k',
output_path
]
try:
subprocess.run(command, check=true, stderr=subprocess.pipe, timeout=300) # 5分钟超时
return f"converted: {output_path}"
except subprocess.calledprocesserror as e:
return f"error converting {input_path}: {e.stderr.decode()}"
except subprocess.timeoutexpired:
return f"timeout converting {input_path}"
def convert_aac_to_mp3(input_dir, output_dir):
start_time = time.time()
total_files = 0
processed_files = 0
converted_files = 0
with threadpoolexecutor(max_workers=os.cpu_count()) as executor:
futures = []
for root, _, files in os.walk(input_dir):
for filename in files:
if filename.lower().endswith('.aac'):
total_files += 1
input_path = os.path.join(root, filename)
rel_path = os.path.relpath(root, input_dir)
output_filename = os.path.splitext(filename)[0] + '.mp3'
output_path = os.path.join(output_dir, rel_path, output_filename)
os.makedirs(os.path.dirname(output_path), exist_ok=true)
futures.append(executor.submit(convert_file, input_path, output_path))
for future in as_completed(futures):
result = future.result()
print(result)
processed_files += 1
if "converted" in result:
converted_files += 1
print(f"progress: {processed_files}/{total_files} files processed")
end_time = time.time()
print(f"\nconversion completed.")
print(f"total files: {total_files}")
print(f"converted files: {converted_files}")
print(f"failed conversions: {total_files - converted_files}")
print(f"total time: {end_time - start_time:.2f} seconds")使用脚本
input_dir = input("请输入包含 aac 文件的目录路径: ")
output_dir = input("请输入 mp3 文件的输出目录路径: ")
convert_aac_to_mp3(input_dir, output_dir)总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持代码网。
