How to create a conversion to transform videos to WebM?

^{Originally posted by AlejandroAkbal May 16, 2022} Hi, I'm trying to optimize all videos that are added to my Post Model. I try to accomplish this goal by converting videos to WebM format.

This is my Post Model:

class Post extends Model implements HasMedia
{
    use InteractsWithMedia;

    public bool $registerMediaConversionsUsingModelInstance = true;

    public function registerMediaCollections(): void
    {
        $this->addMediaCollection('default')
            ->singleFile()
            ->acceptsFile(function (File $file): bool {
                return
                    Str::startsWith($file->mimeType, 'image/')
                    ||
                    Str::startsWith($file->mimeType, 'video/');
            });
    }

    /**
     * @throws InvalidManipulation
     */
    public function registerMediaConversions(\Spatie\MediaLibrary\MediaCollections\Models\Media $media = null): void
    {
        if (!$media) {
            return;
        }

        switch ($media->type === 'video') {

            case true:
                $this->addMediaConversion('default')
                    ->extractVideoFrameAtSecond(1)
                    ->quality(90)
                    ->withResponsiveImages();
                break;

            case false:
                $this->addMediaConversion('default')
                    ->quality(90)
                    ->format('webp')
                    ->withResponsiveImages();
                break;
        }
    }
}

I currently transform the videos by listening to the MediaHasBeenAdded event

class EventServiceProvider extends ServiceProvider
{
    protected $listen = [
        MediaHasBeenAdded::class => [
            ProcessVideoFromMedia::class,
        ],
}

And then running some chained jobs. In that ProcessVideoFromMedia class I replace the current Post Media with a WebM version by adding it again to the Media collection E.g.

        $media->model
            ->addMedia($webmMediaPath)
            ->toMediaCollection();

While this works, I'm creating two Models in the database and wasting some CDN data and queries by uploading the content twice.

What I would like to do is create a Media Manipulation/Conversion that transforms any video to WebM.

Ideally like this:

public function registerMediaConversions(\Spatie\MediaLibrary\MediaCollections\Models\Media $media = null): void
    {
        $this->addMediaConversion('default')
                    ->format('webm') // Important bit
                    ->optimize();
    }
    

I've seen some solutions like https://github.com/spatie/laravel-medialibrary/pull/1279 and https://github.com/spatie/laravel-medialibrary/issues/1277, but I cannot get them to work.

Can someone help me?
