  • How to set the destination folder of a Node.js fluent-ffmpeg screenshot to your AWS S3 bucket using getSignedUrl() ?

    10 juillet 2017, par Madhavi Mohoni

    I’m writing a program to generate .png thumbnails (with the same name, in the same folder) for a set of .mp4 videos in my Amazon S3 bucket. For this example, I’m going to create a /folder/file.png for a /folder/file.mp4 in the bucket. I’ve managed to set the source URL using the s3 object and getSignedUrl as follows :

    var srcurl = s3.getSignedUrl('getObject', {
           Bucket: 'bucket-name',
           Key: '/folder/file.mp4'
         });

    and

    new ffmpeg({ source: srcurl })
        .screenshots({
           count: 1,
           filename: '%f'.substr(0, '%f'.indexOf('.')) + '.png',
           /* To shorten the long string that's returned */
           folder: desturl,
           size: MAX_WIDTH + 'x' + MAX_HEIGHT
         });

    The destination URL has to be the same folder as the source. So I set it as follows :

    var desturl = s3.getSignedUrl('putObject', {
           Bucket: 'bucket-name',
           Key: '/folder/file' + '.png'
         });

    This combination doesn’t work - is there a way to do this correctly ?

  • xdotool to tab to a button on a web page and use the mouse to disable a drop down menu option

    25 juin 2023, par Mash

    I have a Bash script that open a Amazon chime meeting URL in firefox, uses XDOtool to enter a meetig participant name, and tab and mouse click functions. and next uses ffmpeg to stream the video and audio output of the Amazon chime meeting to an RTMP destination.

    


    When this is streamed, the Amazon chime web app has "More" drop down Menu. Within the Menu it has a option to disable the self view. I want to add xdotool commands to disable this self view option from the more drop down menu on the amazon chime web app page.

    


    the Amazon chime meeting URL is - https://app.chime.aws/meetings/

    


    Here is the Bash Script
