There is an error in the code that sets the time for extracting the thumbnails. I think it is a custom modification of the PHPVideoToolkit made for the Drupal version, because it is not present in the original code available in the project repository.

In lines 1855-1856 it reads:

$this->addCommand('-ss', $this->formatTimecode($seconds - 5, $timecode_format, '%hh:%mm:%ss:%ms', $frames_per_second), TRUE);
$this->addCommand('-ss', $this->formatTimecode(5, $timecode_format, '%hh:%mm:%ss:%ms', $frames_per_second), FALSE);

The timecode format is wrong. Milliseconds must use a dot "." as separator. The correct code is:

$this->addCommand('-ss', $this->formatTimecode($seconds - 5, $timecode_format, '%hh:%mm:%ss.%ms', $frames_per_second), TRUE);
$this->addCommand('-ss', $this->formatTimecode(5, $timecode_format, '%hh:%mm:%ss.%ms', $frames_per_second), FALSE);

You owe me a beer for the time wasted debugging this ;)

Nasty bug. Wasted some of my time too.

The ffmpeg error message (for reference): "Invalid duration specification for ss"
