mod_deflate rules conflict with video in Safari

[webtrainingwheels]

Customers report that they have a background video (.mp4, .webm) which disappears only in Safari when WP Rocket is active.

The solution is:
add_filter('rocket_htaccess_mod_deflate', '__return_false');

Examples:

https://secure.helpscout.net/conversation/226153355/18034/?folderId=273766

In both cases the customers also have Cloudflare active, not sure if that's a factor or not.

i just also resolved this issue :

i had to
sudo a2enmod headers
because the way wp-rocket define the line .(?:gif|jpe?g|png|rar|zip|exe|flv|mov|wma|mp3|avi|swf|mp?g|mp4|webm|webp|pdf)$ no-gzip dont-vary
is in the if (mod_headers) ...

<IfModule mod_deflate.c>
# Active compression
SetOutputFilter DEFLATE
# Force deflate for mangled headers
<IfModule mod_setenvif.c>
<IfModule mod_headers.c>
SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)\s*,?\s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding
RequestHeader append Accept-Encoding "gzip,deflate" env=HAVE_Accept-Encoding
# Don’t compress images and other uncompressible content
SetEnvIfNoCase Request_URI \
\.(?:gif|jpe?g|png|rar|zip|exe|flv|mov|wma|mp3|avi|swf|mp?g|mp4|webm|webp|pdf)$ no-gzip dont-vary
</IfModule>
</IfModule>

so i had deflate but not headers, so the setup was partial to make video on ios/safari behind cloudflare

Unfortunately, add_filter('rocket_htaccess_mod_deflate', '__return_false'); didn't solve the issue for me. The site on which I experienced this issue does not use any CDN.

It seems like every time we save WP Rocket settings in any tab, the video works in Safari for a few minutes.

When it works in Safari the server responds with the 200 status code in the file header when inspected using CURL.
curl -i https://mysite.com/my-video.mp4

When it does not work, the status code is the 206 Partial Content.

@laurentdebricon Could you give a bit more details on how you solve this issue? I still experience this issue :(
