Download binary from custom mirror, e.g. S3

[n1ru4l]

Currently, it seems like the binary can only be downloaded from S3. I created przemyslawpluta/node-youtube-dl#351 on node-youtube-dl

Since this package supersedes node-youtube-dl I think there should be an option for a custom mirror.

A possible implementation could use the YOUTUBE_DL_DIRECT_BINARY_DOWNLOAD_URL environment variable:

YOUTUBE_DL_DIRECT_BINARY_DOWNLOAD_URL - download the youtube-dl binary from the given download url, completely ignoring the ** YOUTUBE_DL_HOST** option, while performing no lookup for retrieving the latest version of the binary. This is useful if you are hosting the youtube-dl binary on your own S3 bucket. The platform-specific extension will be appended.
E.g. the value https://xxxxx.s3.xxxxxx.amazonaws.com/2020.11.12-youtube-dl will result in downloading https://xxxxx.s3.xxxxxx.amazonaws.com/2020.11.12-youtube-dl.exe on windows.

Hello, can you give me a valid S3 URL for testing? 🙂

@Kikobeats Here you go :) https://youtube-dl-mirror.s3.eu-central-1.amazonaws.com/2020.11.12-youtube-dl, https://youtube-dl-mirror.s3.eu-central-1.amazonaws.com/2020.11.12-youtube-dl.exe

shipped at youtube-dl-exec@1.1.0, can you confirm to me it works as you expected?

just you need to setup YOUTUBE_DL_HOST environment variable:

YOUTUBE_DL_HOST=https://youtube-dl-mirror.s3.eu-central-1.amazonaws.com/2020.11.12-youtube-dl

or

YOUTUBE_DL_HOST=https://youtube-dl-mirror.s3.eu-central-1.amazonaws.com/2020.11.12-youtube-dl.exe

Also, I added some details about environment variables into the documentation:

why cant we just append .exe based on the detected os? This now requires setting up environment variables based on the OS before installing the package. 😕

it auto-detects the platform and add .exe under windows:
