为下面的python3代码打印已处理文件数量要求只在一条信息上显示处理进度import osimport reimport subprocessimport openpyxlimport mathfrom openpyxlstyles import Font PatternFill Alignment# 支持的视频格式supported_formats = mp4 avi mkv wmv mov
import os import re import subprocess import openpyxl import math from openpyxl.styles import Font, PatternFill, Alignment
支持的视频格式
supported_formats = ['.mp4', '.avi', '.mkv', '.wmv', '.mov', '.flv', '.m2ts', '.ts', '.rm', '.rmvb', '.vob', '.3gp', '.webm', '.hdmov', '.mp4v', '.mpv4', '.divx', '.xvid', '.f4v', '.mpeg', '.asf', '.asx', '.m2t']
需要处理的视频文件夹
video_folder = input("请输入文件夹路径:")
输出Excel文件夹路径
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'
设置表头样式
header_font = Font(bold=True, color='800080') # 紫色 header_fill = PatternFill('solid', fgColor='C5E0B4') header_alignment = Alignment(horizontal='center', vertical='center') headers = ['文件名', '文件路径', '格式', '大小', '时长', '分辨率', '码率', '帧率', '音频码率', '音频采样率', '音频语言', '压缩比率'] for col, header in enumerate(headers, start=1): cell = ws.cell(row=1, column=col, value=header) cell.font = header_font cell.fill = header_fill cell.alignment = header_alignment
锁定表头
ws.freeze_panes = 'A2'
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
遍历所有视频文件,获取视频信息、音频信息和音频语言,并写入Excel文件
for row, video_file in enumerate(video_files, start=2): # 获取文件名 file_name = os.path.basename(video_file)
# 获取文件大小并进行单位换算
size = os.path.getsize(video_file)
if size < 1024:
size_str = f'{size} B'
elif size < 1024 * 1024:
size_str = f'{size / 1024:.2f} KiB'
elif size < 1024 * 1024 * 1024:
size_str = f'{size / 1024 / 1024:.2f} MiB'
else:
size_str = f'{size / 1024 / 1024 / 1024:.2f} GiB'
# 使用mediainfo获取视频信息 / 音频信息和音频语言
video_result = subprocess.run(['mediainfo', '--Inform=Video;%Format%|%Width%x%Height%|%BitRate/String%|%FrameRate%|%Duration/String3%', video_file], stdout=subprocess.PIPE)
video_output = video_result.stdout.decode().strip()

# 解析输出结果

# 时长取整
duration = duration.split('.')[0]

duration = f'{h}:{m}:{math.ceil(float(s))}'
# 以分钟计算的时长
duration_minutes = int(h) * 60 + int(m) + math.ceil(float(s)) / 60
# 计算压缩比率
ratio = round(duration_minutes / size * 1000000000, 2)
# 使用正则表达式替换码率数据中第一个数字和第二个数字之间的空格
bitrate = re.sub(pattern, r'\1\2', bitrate)
# 写入Excel文件
ws.cell(row=row, column=1, value=file_name)
ws.cell(row=row, column=2, value=os.path.dirname(video_file)) # 写入文件夹路径
ws.cell(row=row, column=3, value=format)
ws.cell(row=row, column=4, value=size_str) # 写入文件大小
ws.cell(row=row, column=5, value=duration)

ws.cell(row=row, column=12, value=ratio)
# 打印进度
print(f'已处理 {row-1}/{len(video_files)} 个文件', end='\r')
自动调整列宽
for col in ws.columns: max_length = 0 column = col[0].column_letter for cell in col: try: if len(str(cell.value)) > max_length: max_length = len(str(cell.value)) except: pass adjusted_width = (max_length + 2) ws.column_dimensions[column].width = adjusted_width + 1
调整L列的列宽和对齐方式
l_col = ws['L'] max_length = 0 for cell in l_col: try: if len(str(cell.value)) > max_length: max_length = len(str(cell.value)) except: pass l_col_width = max_length + 5 # 列宽加5 ws.column_dimensions['L'].width = l_col_width for cell in l_col: cell.alignment = Alignment(horizontal='left') # 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) print(f'视频信息已保存到 {excel_file_path}')
