As in a Ruby block to upload a large file to S3, pre-encoded it in Base64?

You must download a large media file (more available RAM) in S3, the pre-coding it in Base64.

Help to optimize the Ruby code to read a file, encode to Base64 and then loading up on S3 was performed in blocks.
blob = Base64.encode64( IO.binread('big_file.mp4')), 'rb' )
 key: target_name,
 body: blob
 acl: 'public-read'

Documentation Base64.encode64 is not possible to process the file stream in chunks. Are there any tricks?

Official S3 Ruby client is able to upload files by chunks (at least so says the documentation). (section Uploading Files)
Yes, I know that. It was about chunked transfer encoding to Base64.encode64. - alfonso56 commented on June 26th 19 at 14:09
Then you need to create a class that will be at the entrance to the path to the file and implement the IO interface, and inside this class will encode in base64 chunks. - jayme7 commented on June 26th 19 at 14:12
: show a simple example - alfonso56 commented on June 26th 19 at 14:15
