Q: What is sufficient information, including any required input files, to reproduce the bug and confirm a potential fix?

  • I have searched bugzilla and google, and have spent several hours trying numerous options to ffmpeg/ffprobe but cannot get around this issue.
  • Not only can't Youtube process these mp4 (stuck at 0% processed), but Handbrake, and other video converter tools fail to process the videos as well.
  • Chrome, Firefox, and IE, all play the videos fine:
    <html><body>
    <video controls src="http://MediaHTTP.IQM2.com/LincolnCityOR/1531_480.mp4"/>
    </body></html>
    
    so the files are not corrupted.
  • ffmpeg/ffprobe can read all .mp4s on http://lincolncityor.iqm2.com/Citizens/Media.aspx that were created before 1-Dec-2016. ffmpeg/ffprobe return "unspecified pixel format" on all .mp4s on http://lincolncityor.iqm2.com/Citizens/Media.aspx that were created after 1-Dec-2016:
