Implementation of hook_file_default_displays() {media module} makes it impossible to export image display settings via features

Question

This is a issue I am dealing with for days. It looks like is related to: https://drupal.org/node/1702700

I've created a feature relying on media, file_entity and media_youtube, vimeo... whose main purpose is to embed youtube, vimeo videos etc.

I've correctly set up the file_entity displays weights: Structure » File types » Video » Manage file display so that the thumbnails shows ok

    e.g 
    "Large filetype icon"   weight: 50 
    "Youtube Image Preview" weight: -40.
    {GOOD}

After complete feature export,
"Large filetype icon" weight: 0 
"Youtube Image Preview" is set 2.
{WRONG}

I even edited manually the feature's .info and default_displays.inc file with no luck.

Secondly, there are also feature overrides unable to revert. It looks like somethings alters the file display weights.

Answer 1

The problems comes from the heart of Media module which programatically add default overrides.

I have managed to solve the problem in 2 steps: (1) Sunk the Media Icon to the bottom

apply a patch to Media module:

(2) I exported my feature but manually edited the File Display like this:

YOURFEATURE.features.field.inc

For Default the order is

Vimeo 
Vimeo Preview 
Youtube 
Youtube Preview

For Preview the order is

Vimeo Preview 
Vimeo 
Youtube Preview
Youtube
