Warning: preg_match() expects parameter 2 to be string, object given in FFMpeg\FFProbe\OptionsTester->has() (line 44 of vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\FFProbe\OptionsTester.php)

Can you provide the full stack trace for the error?

I have the same issue. This is the full stack trace:

This is actually a bigger deal than it seems, as it can lead to ffprobe and ffmpeg not being loaded in certain circumstances.

I believe the issue is that this module provides a cache for the phpffmpeg library, but data being returned to ffmpeg needs to be a string, while Drupal's cache normally returns and object.

The attached patch fixed the issue for me.

cache->get() either returns an object or nothing, there is no reason to ever return $return. The common pattern for this would be something like this:

if ($cache = $this->cache->get($this->getCid($id)) {
return $cache->data;
}

Updated the patch. I still left the return FALSE fallback because \Doctrine\Common\Cache\Cache seems to define it.

Yes, keeping that makes sense.

Applying the patch #11 fixes this crash. Thanks!
