• Extract thumbnail from video in amazon s3 and store it in amazon s3 [closed]

  24 juin 2021, par Kanav Raina

  I want to extract thumbnail from video and store it on s3.

  


  import ffmpeg

url="https://link_to_s3_video.mp4"

(
    ffmpeg
    .input(url, ss='00:00:03')  
    .output("frame.png", pix_fmt='rgb24', frames='1')  
    .overwrite_output()
    .run()
)


  


  I am able to extract image but now how should I pass this image to file_upload function and store it on s3

  


  def file_upload(file, filename):
    link = f"https://{PUBLIC_BUCKET_NAME}.s3.us-east-2.amazonaws.com/images/{filename}"
    try:
        s3.Object(PUBLIC_BUCKET_NAME, f"images/{filename}").load()
    except ClientError as e:
        if e.response['Error']['Code'] == "404":
            try:
                s3_client.upload_fileobj(
                    file,
                    PUBLIC_BUCKET_NAME,
                    f"images/{filename}",
                    ExtraArgs={'ACL': 'public-read'}
                )

                return 200, link
            except ClientError as e:
                logging.error(e)
                return 500, ""
        else:
            return 500, ""
    else:
        return 409, link


  


  Thanks

  


• Amazon S3 : how to combine all images into a video ?

  9 septembre 2021, par scientiffic

  I'm in my Rails app, I enable users to upload images, which get processed using ffmpeg to create a video slideshow.

  



  I have this working locally, but am wondering how to do this when deploying the app using Heroku. In particular, I know Heroku has limited storage and has a read-only filesystem, so using Carrierwave without S3 or an external storage option doesn't seem like an option.

  



  But how would I run a task like the following using S3, where I combine all images into a video ?

  



  The ffmpeg command is

  



  ffmpeg -r 5 -i https://s3.amazonaws.com/[]/uploads/image/image_file/26/img%03d.jpg output.mp4 -y


  



  And the AWS "folder" contains the following :
https://s3.amazonaws.com/[]/uploads/image/image_file/26/img001.jpg
https://s3.amazonaws.com/[]/uploads/image/image_file/26/img002.jpg
https://s3.amazonaws.com/[]/uploads/image/image_file/26/img003.jpg

  



  When I try to do the following, I get an error with ffmpeg not knowing what to do with :

  



  https://s3.amazonaws.com/[]/uploads/image/image_file/26/img%03d.jpg


  



  Note, this whole video compilation process works fine for me locally, so I know in theory it should work.

  


• install ffmpeg on amazon ecr linux python

  27 mai 2024, par Luka Savic

  I'm trying to install ffmpeg on docker for amazon lambda function.
Code for Dockerfile is :

  


  FROM public.ecr.aws/lambda/python:3.8

# Copy function code
COPY app.py ${LAMBDA_TASK_ROOT}

# Install the function's dependencies using file requirements.txt
# from your project folder.

COPY requirements.txt  .
RUN  yum install gcc -y
RUN  pip3 install -r requirements.txt --target "${LAMBDA_TASK_ROOT}"
RUN  yum install -y ffmpeg

# Set the CMD to your handler (could also be done as a parameter override outside of the Dockerfile)
CMD [ "app.handler" ]


  


  I am getting an error :

  


   > [6/6] RUN  yum install -y ffmpeg:
#9 0.538 Loaded plugins: ovl
#9 1.814 No package ffmpeg available.
#9 1.843 Error: Nothing to do
