从gif转换的mp4没有在网络浏览器中显示

I am trying to convert animated GIFs to MP4 files using ffmpeg. Only this convert GIF to MP4:

  exec('ffmpeg -i ' . $destinationPath . $filename . ' -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" ' . $destinationPath . $newFilename);

And I can play it in my pc when download it from server, but it's didn't want to pay in browser. Browser returns me this error: enter image description here

After that GIF to MP4 converor I get one image for thumbnail image and that is works fine:

exec("ffmpeg -i " . $destinationPath . $video . ".mp4 -ss  00:00:01.000 -vframes 1 ".storage_path().$folderNameThumb."/media.png");

and it's shows me a valid frame of GIF. Can anybody help me how to fix this problem with video?

ffprobe output

Here is what I get from one MP4 file (run ffprobe filename.mp4):

 Metadata:
major_brand     : isom
minor_version   : 512
compatible_brands: isomiso2mp41
encoder         : Lavf56.40.101
Duration: 00:00:02.16, start: 0.000000, bitrate: 593 kb/s
Stream #0:0(und): Video: mpeg4 (Simple Profile) (mp4v / 0x7634706D), yuv420p, 500x312 [SAR 1:1 DAR 125:78], 589 kb/s, 8.33 fps, 8.33 tbr, 12800 tbn, 25 tbc (default)
Metadata:
handler_name    : VideoHandler

Because I use Laravel this is method for return media:

public function getGifImage(Media $media)
{
    $path = storage_path() . '/uploads/gif/' . $media->content;
    if (file_exists($path)) {
        return response()->download($path, null, [], null);
    }
}
