PHP-FFMpeg Error while opening encoder for output stream

Question

I'm trying to use this PHP-FFMpeg library, but I'm keep getting errors like

Error while opening encoder for output stream #0:0

This is my PHP code

private function createTeaserVideos($fullVideoPath, $databasePath, $uploadPath) {
        $ffmpeg = FFMpeg::create([
            'ffmpeg.binaries' => '/usr/bin/ffmpeg',
            'ffprobe.binaries' => '/usr/bin/ffprobe',
            'timeout'          => 0,
        ]);

        $ffmpeg->getFFMpegDriver()->listen(new \Alchemy\BinaryDriver\Listeners\DebugListener());
        $ffmpeg->getFFMpegDriver()->on('debug', function ($message) {
            var_dump($message);
        });

        // Create teaser_video_thumb
        $videoNameThumb = $this->randomTimeString() . '-thumb.mp4';
        $video = $ffmpeg->open($fullVideoPath);
        $video
            ->filters()
            ->resize(new \FFMpeg\Coordinate\Dimension(400, 280))
            ->synchronize();
        $video->save(new \FFMpeg\Format\Video\X264('aac', 'libx264'), $uploadPath . $videoNameThumb);
    }

So what I'm trying to do here. User uploads his video and I'm trying to resize it and create one smaller video for the preview. The problem that I'm keep getting it is

I can't figure out what is the problem or how to solve it. Can someone please help me out? I'm using Ubuntu 16 and I have installed ffmpeg via apt-get install ffmpeg. If you need any additional infomations, please let me know and I will provide. Thank you

1. Please show the actual `ffmpeg` command being executed by your script. 2. Your `ffmpeg` is ancient. [Download](https://johnvansickle.com/ffmpeg/) a build from the git master branch and try again. 3. Refer to [FFMPEG (libx264) “height not divisible by 2”](https://stackoverflow.com/q/20847674/1109017). — llogan, Jan 04 '19 at 19:28

The solution for me was following. First i have reinstalled my ffmpeg with more latest version. I did a following

cd
wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-amd64-static.tar.xz
tar xvf ffmpeg-git-amd64-static.tar.xz
sudo mv ffmpeg-git-20190101-amd64-static/ffmpeg ffmpeg-git-20190101-amd64-static/ffprobe /usr/local/bin/
whereis ffmpeg
rm -f ffmpeg-git-amd64-static.tar.xz

Then I have changed the code, to look like following

private function createTeaserVideos($fullVideoPath, $databasePath, $uploadPath) {
    $ffmpeg = FFMpeg::create([
        'ffmpeg.binaries' => '/usr/local/bin/ffmpeg',
        'ffprobe.binaries' => '/usr/local/bin/ffprobe',
        'timeout'          => 0,
    ]);

    // Create teaser_video_thumb
    $videoNameThumb = $this->randomTimeString() . '-thumb.mp4';
    $video = $ffmpeg->open($fullVideoPath);
    $video
        ->filters()
        ->resize(new \FFMpeg\Coordinate\Dimension(THUMBNAIL_WIDTH, THUMBNAIL_HEIGHT))
        ->synchronize();

    $format = new \FFMpeg\Format\Video\X264();
    $format->setVideoCodec('libx264');
    $format->setAudioCodec('aac');
    $format->setAdditionalParameters( [ '-crf', '10'] );

    $video->save($format, $uploadPath . $videoNameThumb);

    return [
        'thumb' => $databasePath . $videoNameThumb,
    ];
}

Another problem that I had, was my new video height was not dividable by / 2. So it looks like, ffmpeg needs to have height which can be divided by 2.
