• Save screenshots taken with FFmpeg into Amazon S3 bucket

  30 mars 2021, par HomeAlone

  In my python app I take screenshots of videos. I save them locally and it works just fine but now I want to save them in an Amazon S3 bucket.

  


  subprocess.run(["ffmpeg", "-ss", "00:00:30", "-i", src, "-map", "0:v", "-vframes", "1", "pipe:pic.jpeg | aws s3 cp - s3://mypublicbucket"])


  


  I get an Unable to find a suitable output format when running this command. What I try to do is to upload the picture straight into my public amazon bucket.

• Getting An Indexed Color Table to Encode Custom Filetype FFmpeg

  16 février 2018, par ThoseKind

  I am messing with a custom image format to be supported in FFmpeg with a custom encoder and decoder. In order to encode images, it seems like using an indexed color table is a good approach, but I am unsure if this is something that FFmpeg can already provide me or if this is something that I will have to build functionality for myself.

  Does FFmpeg have built-in functionality to get an indexed color table from an input stream ?

  If so, what are they ?

  If not, are there any good resources to learn about the best way to do this ?
