视频格式

视频文件夹

video_folder = input('请输入文件夹路径：')

输出Excel路径

excel_folder = '.'

输出Excel文件名

excel_file = 'video_info.xlsx'

正则表达式匹配码率数据中的空格

pattern = re.compile(r'(\d+)\s+(\d+)')

创建Excel文件

wb = openpyxl.Workbook() ws = wb.active ws.title = 'Video Info'

获取视频文件列表（包括子目录）

video_files = [] for root, dirs, files in os.walk(video_folder): for file in files: for format in supported_formats: if file.endswith(format): video_files.append(os.path.join(root, file)) break

锁定表头

设置表头样式

处理失败文件个数

遍历所有视频文件

总计处理文件数

调整L列左对齐

保存Excel文件

if not os.path.exists(excel_folder): os.makedirs(excel_folder) excel_file_path = os.path.join(excel_folder, excel_file) wb.save(excel_file_path)

打印处理失败文件个数和总计处理文件数

print( f'已完成，处理成功 {success_count} 个文件，处理失败 {failed_count} 个文件，视频信息已保存到 {excel_file_path}' )
