  • WebM file not seekable in Chrome when loaded through PHP (other browsers work)

    13 avril 2014, par Zoon

    I am having a mind-boggling problem, I just can't seem to resolve.

    Providing a WebM file through PHP is nothing new in my world, and I even know how to work with HTTP 206 Partial Content. But for some reason Chrome does not like it.

    A simple HTML5 video playback

    <video width="640" height="360" poster="picture/preview/V00000006.jpg" controls="controls" preload="preload">
    
    <source type="video/webm" src="/video/V00000006.webm">
    
</source></video>

    where /video/V00000006.webm is rewritten to a PHP-file in Apache, will playback just fine.
    But in Chrome the seekbar is not effective. When clicking on the seekbar the player will freeze and no longer playback until page is refreshed. Firefox handles it just fine !

    If I change /video/V00000006.webm to be a direct link to the same video it works just fine. I even compared the network requests between the two versions (with and without PHP) and there is barely any difference in the first request, but the second is failing in the PHP-delivered video.

    Initial request and seek request for Apache-delivered video file :

    echo fread($f, $chunk);
    
    flush();
    

    
    $pos += $chunk;
    
}
    
?>

    Please note, entering the PHP-delivered video URL directly into the browser does not make a difference from showing it in a HTML page.

    I hope someone has an answer to why seeking might not work. Let me know if you have any suggestions.

    Thanks !

  • Rotate video, output maximum 1920 x 1080 pixels

    9 avril 2014, par Fabien Biller

    I used

    ffmpeg.exe -ss 310 -i "H:\_REC\100MEDIA\someavi.AVI" -ss 0 -t 14 -vf "rotate=&#39;54*PI/180:ow=hypot(iw,ih):oh=ow&#39;" -vf scale=1920:1080 "H:\_REC\100MEDIA\somemp4.mp4"

    which should rotate the video(currently 1920 x 1080, MJPEG, 30fps) around 54° and fit it into 1920 x 1080 Pixels.

    What it does is, it ignores the -vf "rotate=&#39;54*PI/180:ow=hypot(iw,ih):oh=ow&#39;" -vf scale=1920:1080 and returns the snippet.

    What to change ?

    PS : ffmpeg version N-59696-gc0a33c4
