  • OS X uploads .mp4 as quicktime ? [on hold]

    15 janvier 2014, par daled

    I'm running into a rather peculiar issue uploading .mp4 from any browser on OS X. I'm using ffmpeg to convert files and .mp4's uploaded from OS X are causing issues.

    First off, the file I'm uploading is not corrupt. Here is the relevant exiftool output on the file I'm uploading. This is the original file on the client.

    File Type                       : MP4
    
MIME Type                       : video/mp4
    
Major Brand                     : MP4 Base w/ AVC ext [ISO 14496-12:2005]
    
Minor Version                   : 0.0.0
    
Compatible Brands               : avc1, isom

    Now here's the exiftool output on the server for the same file :

    File Type                       : MOV
    
MIME Type                       : video/quicktime
    
Major Brand                     : Apple QuickTime (.MOV/QT)
    
Minor Version                   : 2005.3.0
    
Compatible Brands               : qt

    Ffmpeg will recognize the first file just fine. Everything will work perfectly and I can convert it however I choose. But the second file, I'll get this error :

    [mov,mp4,m4a,3gp,3g2,mj2 @ 0x3855180] stream 0, error opening alias: path='/Users/', dir='20130602-113438', filename='GOPR0018.MP4', volume='Macintosh HD', nlvl_from=-1, nlvl_to=-1
    
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x3855180] stream 1, error opening alias: path='/Users/', dir='20130602-113438', filename='GOPR0018.MP4', volume='Macintosh HD', nlvl_from=-1, nlvl_to=-1

    Here is the FFmpeg command I am using :

    ffmpeg -y -probesize 2147483647 -analyzeduration 2147483647 -i "'.$oldFilename.'" -vcodec libtheora -q:v 0 -acodec libvorbis -q:a 0 "'.$newFilenameOGG.'" 2>&1

    This command works fine with every file type besides this file. It seems like ffmpeg is seeing the uploaded file as a corrupt quicktime file instead of a valid mp4 file. So my question is, how is this metadata magically changing ?
