修改后的代码如下：

import os import glob from natsort import natsorted

dir_path = r'E:\home\up' output_dir = r'E:\home\up\1'

当前文件夹下的所有mp4路径

L = [] for root, dirs, files in os.walk(dir_path): files = natsorted(files) for file in files: if os.path.splitext(file)[1] == '.mp4': file_path = os.path.join(root, file) L.append(file_path)

生成ffmpeg命令

commands = [] for l in L: ts_file = os.path.join(os.path.dirname(l), os.path.splitext(os.path.basename(l))[0] + '.ts') commands.append(f"ffmpeg -i "{l}" -vcodec copy -acodec copy -bsf:v h264_mp4toannexb "{ts_file}"")

获取文件名 + '.mp4'

new_file_name = os.path.splitext(os.path.basename(L[0]))[0][1:] + '.mp4' concat_command = ( f'ffmpeg -i "concat:{"|".join([os.path.join(os.path.dirname(l), os.path.splitext(os.path.basename(l))[0] + ".ts") for l in L])}" ' '-acodec copy -vcodec copy -bsf:a aac_adtstoasc ' f'"{os.path.join(output_dir, new_file_name)}"' )

执行ffmpeg命令

for command in commands: os.system(command)

os.system(concat_command)

删除ts文件

for ts_file in glob.glob(os.path.join(dir_path, '*.ts')): os.remove(ts_file)

输出文件命名

for mp4_file in glob.glob(os.path.join(output_dir, '*.mp4')): file_name = os.path.splitext(os.path.basename(mp4_file))[0][1:] if '00' in file_name: # 仅替换英文字母之后的00 for i in range(len(file_name)-2): if file_name[i:i+2] == '00' and file_name[i+2].isalpha(): file_name = file_name[:i] + '-' + file_name[i+2:] # 替换h_开头的00 if file_name.startswith('h_') and file_name[2:4] == '00': file_name = 'h-' + file_name[4:] file_name = file_name.strip('0123456789.-_') # 截取到最后一个英文字母之前 new_file_name = '' for i in range(len(file_name)-1, -1, -1): if file_name[i].isalpha(): new_file_name = file_name[:i] break new_file_name += '.mp4' os.rename(mp4_file, os.path.join(output_dir, new_file_name)
