For some reason ffmpeg-php has started generating blue tinted thumbnails when generating thumbnails for .flv files downloaded from youtube, since the site I'm working on moved servers. I have no idea why, or how to track this issue down - so any help you could provide would go a long way, since I have no experience with ffmpeg.
The code that does it:
@exec("".$this->smclass->config['ffmpeg_path']." -i ".$this->thumb_info['video_path']." -an -ss ".$create_time." -t 00:00:01 -r 1 -y -s ".$this->thumb_info['thumb_width']."x".$this->thumb_info['thumb_height']." ".$this->thumb_info['save_dir'].$this->thumb."%d.jpg");
This code has not changed since the move, and I'm under the impression that whoever setup ffmpeg did it the "same way" as they did for the previous server, however on the off chance they didn't - what could be doing this? Is there some setting, or bug in an older (or newer) version that does this?
