Why it's not possible to convert .mp4 with "X265"?

[Diogo2550]

I added the value "libx265" to the return array of the "X264" class and it was possible to convert to X265. Is there any reason why this functionality is not present?

@Diogo2550 , you might want to give this a try:

<?php

namespace YOURNAMESPACE;

use FFMpeg\Format\Video\X264;

/**
 * A custom class for encoding videos with the H.265 (x265) codec, based on the X264 class.
 */
class X265 extends X264
{
    /**
     * Constructor to set audio and video codecs.
     *
     * @param string $audioCodec The audio codec to use. Defaults to 'aac'.
     * @param string $videoCodec The video codec to use. Defaults to 'libx265' for H.265 encoding.
     */
    public function __construct($audioCodec = 'aac', $videoCodec = 'libx265')
    {
        parent::__construct($audioCodec, $videoCodec);
    }

    /**
     * Get the available video codecs, in this case, only 'libx265'.
     *
     * @return array An array containing the available video codecs.
     */
    public function getAvailableVideoCodecs()
    {
        return array('libx265');
    }
}

Now, to use this custom class, you can instantiate it with the desired codecs like so:
new X265('aac','libx265');
