使用 Google Cloud Function 创建带有子目录路径的视频缩略图

Question

我正在通过休息 api 将视频上传到 google 云存储桶并添加一个功能以使用 python 生成缩略图。代码在主目录上工作，但我的视频上传到 sub/sub/ 目录，所以我的代码不工作。

import os
from google.cloud import storage
from subprocess import check_output
from videoprops import get_video_properties

client = storage.Client()
def hello_gcs(data, context):
  
  print(context)
  print(data)

  if data['contentType'].startswith('video/'):

     bucket = client.get_bucket(data['bucket'])
     name = data['name']
    
     file_name = '/tmp/'+ name
     print(file_name)

     thumbnail_file_name = '/tmp/' + name.split('.')[0] + '.jpg'
     print(thumbnail_file_name)

     try:
          os.remove(file_name)
     except OSError:
          pass

     try:
          os.remove(thumbnail_file_name)
     except OSError:
          pass

     print("File has been removed")

   
     blob = bucket.get_blob(name)
     blob.download_to_filename(file_name)

     print("Video Downloaded")

     props = get_video_properties(file_name)

     

     if os.path.exists(file_name):
          print("NEW MP4 EXISTS")            
          check_output('ffmpeg  -itsoffset -4  -i '+file_name+' -vcodec mjpeg -vframes 1 -an -f rawvideo -s '+str(props['width'])+'x'+str(props['height'])+' '+thumbnail_file_name, shell=True)
          thumbnail_blob = bucket.blob('thumbnail.jpg')
          thumbnail_blob.upload_from_filename(thumbnail_file_name)
     else:
          print("MP4 not created")
         
     print("uploaded")

  else :
     print("Not a Video")

所以我只能访问 tmp 但不能创建像 /tmp/Upload/Video/232/video.mp4.

这样的文件夹

谢谢达美什

这里我的子目录视频代码可以生成缩略图并在同一目录中上传。

    import os
from google.cloud import storage
from subprocess import check_output
from videoprops import get_video_properties

client = storage.Client()


def hello_gcs(data, context):
  
  print(context)
  print(data)

  if data['contentType'].startswith('video/'):

     bucket = client.get_bucket(data['bucket'])
    
     name = data['name']
     os.makedirs('/tmp/'+os.path.dirname(name), exist_ok=True) 
     file_name = '/tmp/'+ name
     print(file_name)

     thumbnail_file_name = '/tmp/' + name.split('.')[0] + '.jpg'
     print(thumbnail_file_name)

     try:
          os.remove(file_name)
     except OSError:
          pass

     try:
          os.remove(thumbnail_file_name)
     except OSError:
          pass

     print("File has been removed")

   
     blob = bucket.get_blob(name)
     blob.download_to_filename(file_name)

     print("Video Downloaded")

     props = get_video_properties(file_name)

     

     if os.path.exists(file_name):
          print("NEW MP4 EXISTS")            
          check_output('ffmpeg  -itsoffset -4  -i '+file_name+' -vcodec mjpeg -vframes 1 -an -f rawvideo -s '+str(props['width'])+'x'+str(props['height'])+' '+thumbnail_file_name, shell=True)
          thumbnail_blob = bucket.blob(os.path.dirname(name)+'/thumbnail.jpg')
          thumbnail_blob.upload_from_filename(thumbnail_file_name)
      
     else:
          print("MP4 not created")

     
     print("uploaded")

  else :
     print("Not a Video")
