Trying to open file with PHP-FFMpeg after it was encoded once

in the same PHP process I'm trying to open a file that was manipulated and saved, and then I'm trying to open it with as a new FFMpeg\Video. For example, in the same process:

Open -> original.MOV
  Manipulate & save to -> new.mp4
    Open -> new.mp4

However when I'm trying to open the manipulated file I get this InvalidArgumentException exception:

InvalidArgumentException: Unable to detect file format, only audio and video supported

It's thrown by the FFMpeg::open() after it could not detect that it's a either Video or Audio stream.

FFMpeg::open() 

public function open($pathfile)
{
    if (null === $streams = $this->ffprobe->streams($pathfile)) {
        throw new RuntimeException(sprintf('Unable to probe "%s".', $pathfile));
    }

    if (0 < count($streams->videos())) {
        return new Video($pathfile, $this->driver, $this->ffprobe);
    } elseif (0 < count($streams->audios())) {
        return new Audio($pathfile, $this->driver, $this->ffprobe);
    }

    throw new InvalidArgumentException('Unable to detect file format, only audio and video supported');
}

The filters I applied to the video are audio mute and speedup (setpts).

So I wonder, why FFMpeg doesn't recognise it as video?

Solution

  • Apparently I was trying to open a video file that was corrupted or incomplete. Anyway, the problem wasn't with the code or god forbid - php-ffmpeg. 🙃
