Reg - Video File Chunk issue

Hi Team,

In one of the projects, I have faced the issue of chunking the file. Below
is the code I used to chunk the file.

$fp = fopen($mediaUrl, 'r');
$segment_id = 0;

while (!feof($fp)) {
      $chunk = fread($fp, 4 * 1024 * 1024); // chunk the file as 4MB
}
fclose($fp);

If we try to push any video file with above 10MB, we didn't get the proper
chunk file. Its generated randomly with different bytes.

Can you please help with this?

Thanks & Regards,
