I had to update the prefered extensions map in src/Symfony/Component/Mime/Resources/bin/update_mime_types.php

-   'yaml' => ['application/yaml'],
-   'yml' => ['application/yaml'],
+   'yml' => ['application/yaml'],
+   'yaml' => ['application/yaml'],

This is the only way to make

• 'application/yaml' first type for 'yaml' extension
• 'application/yaml' first type for 'yml' extension
• 'yaml' first extension for 'application/yaml' type
• 'yml' second extension for 'application/yaml' type

---

If it's still possible before 7.2 ?

(last one was 8 months ago)

This one and the next one seem suspicious to me.

[smnandre]

application/mp4 is a registered mime type

• https://www.iana.org/assignments/media-types/application/mp4
• https://datatracker.ietf.org/doc/rfc4337/

Do you think we should add a special case for it to grant the first place to "video/mp4" (as we do for mp3 and audi) ?

symfony/src/Symfony/Component/Mime/Resources/bin/update_mime_types.php

Line 92 in fa0a13f

'mp3' => ['audio/mpeg'],

Done it / cf last comment

[smnandre]

Updated preferences for aac (same thing), mp4 and mpeg4

Yaml has changed due to our preferences (not sure why it did not in first commit, and a small new change for "vor" in the meanwhile)

[fabpot]

Let's not change this one as this is commonly used.

Ok i understand where the problem is coming from.

I updated the issue comment and added a comment in the update_mime_types.php file

(and fixed the MimeTypes.php file)

Thank you @smnandre.
