使用 Google Cloud 在视频中添加水印 function python

Question

I am adding watermark in uploaded video by http google cloud function but my code is return on ffmpeg non zero. my python code

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


def hello_world(request):

client = storage.Client()
bucket = client.get_bucket('bucket_name')
request_json = request.get_json()
req_data = request.get_json()
name = req_data['file']
videofile_name = req_data['file_name']
os.makedirs('/tmp/'+os.path.dirname(name), exist_ok=True)
file_name = '/tmp/' + name
output_file_name = '/tmp/' + name.split('.')[0] + '_.'+name.split('.')[1]
print(output_file_name)
logo_path = '/temp/watermark.png'
logo_name = 'watermark.png'
print('logo found')

print(file_name)

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

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

print("File has been removed")

# Downloading the video to the cloud functions
blob = bucket.get_blob(name)
blob.download_to_filename(file_name)

blob_logo = bucket.get_blob(logo_name)
blob_logo.download_to_filename(logo_path)

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)
    # 19-7-2020
    check_output('ffmpeg  -i '+file_name+' -i '+logo_path +
                 ' -filter_complex overlay=10:10 -codec:a copy -preset ultrafast -async 1 '+output_file_name, shell=True)
    thumbnail_blob = bucket.blob(
        os.path.dirname(name) + '/'+videofile_name)
    thumbnail_blob.upload_from_filename(output_file_name)
    # -------------------------------------
else:
    print("MP4 not created")

print("uploaded")

In this code accessing video add watermark also accessing from bucket and applying with ffmpeg and uploading.

error is:-

raise CalledProcessError(retcode, process.args, subprocess.CalledProcessError: Command 'ffmpeg -i /tmp/Upload/Video/1060/ad69ec74-49db-4fdb-b118-d23b9468a7b8.mp4 -i /temp/watermark.png -filter_complex overlay=10:10 -codec:a copy -preset ultrafast -async 1 /tmp/Upload/Video/1060/ad69ec74-49db-4fdb-b118-d23b9468a7b8_.mp4' returned non-zero exit status 1.

I have solved and using with http request base trigger in google cloud function. May be help to someone in future
