Test_20100411_Vdubtestrgbcube4secs_ifps.ogv with empty thumbnail
Between 03:23, 8 April 2010 and 08:40, 9 April 2010 new video uploads started
to render with empty or corrupt thumbnails (Firefox, Google Chrome, Opera and
Safari, with cache and file purging; thumbtime also tested). New uploads are
still rendering incorrectly. I *believe* I have eliminated file corruption
because the file uploaded is identical to the file on my PC (I download the
file from mediawiki and use emacs to compare).
See
http://commons.wikimedia.org/wiki/Commons:Village_pump#Video_thumbnails_corrupt_since_9_April
Duplicated problem on skins: Monobook, Vector and Classic. Other skins not
tried.
How to replicate:
1: choose any small video from Category:Calibration videos at
http://commons.wikimedia.org/wiki/Category:Calibration_videos and download to
computer
2: upload same file with name prefixed with "Test_reupload_"; click the "ignore
warning and save anyway" button
3: see the corrupt or empty video thumbnail
