Arquivos Mp4 estão baixando em vez de serem exibidos inline

Em teoria, mp4 deve ser servido inline:

discourse/lib/file_helper.rb at 2d615863d2613a7237451b8997c3c8c6583e7ae8 · discourse/discourse · GitHub

o que usa:

discourse/lib/file_helper.rb at 2d615863d2613a7237451b8997c3c8c6583e7ae8 · discourse/discourse · GitHub

No meta, o discourse também força o download de mp4: https://d11a6trkgmumsb.cloudfront.net/original/4X/3/f/0/3f09f895d21cf0ae897d90c947abb816830b00a2.mp4

Algo está fazendo com que os arquivos mp4 ainda sejam servidos com content-disposition: attachment. Precisamos investigar e corrigir.

Para constar, houve um tópico sobre isso e o Nat trabalhou na questão:

Incorrect mime-types (content-type header) for mp4 and js

Just a quick update - The ext_mime_db above that we use follows IANA Media Types defined here - https://www.iana.org/assignments/media-types/media-types.xhtml. Unfortunately, this means that mp4 is correctly application/mp4 [Screenshot 2025-01-03 at 12.51.40 AM] Though, looking into our S3 uploader implementation further, I do see that we are adding Content-Disposition header "attachment" for pretty much every upload that is not an image, but it feels like it was only intended…
