import os from natsort import natsorted

获取当前文件夹路径

current_dir = os.path.dirname(os.path.abspath(file))

存储当前文件夹下的所有mp4文件路径

L = [] for root, dirs, files in os.walk(current_dir): files = natsorted(files) for file in files: # 只处理mp4文件 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: commands.append(f"ffmpeg -i '{l}' -vcodec copy -acodec copy -bsf:v h264_mp4toannexb '{os.path.join(current_dir, os.path.splitext(l)[0] + '.ts')}' ")

concat_command = f'ffmpeg -i 'concat:{'|'.join([os.path.join(current_dir, os.path.splitext(i)[0] + '.ts') for i in L])}' -acodec copy -vcodec copy -bsf:a aac_adtstoasc '{os.path.join(current_dir, 'output.mp4')}'

rm_command = f'rm '{os.path.join(current_dir, '*.ts')}'

执行ffmpeg命令

for command in commands: os.system(command)

os.system(concat_command) os.system(rm_command)
