Note: html5 player doesn’t have any known issues like this.

Flash player appears to require videos to have extra meta data added using qt-faststart.

ffmpeg command needs this entry at the end of the command:

-movflags faststart

If you have current videos that need to be fixed, then please get us a list of videos and we can patch them all.

– Full path to the video is required.

Also change this line in your mechbunny config.php file.

$forceEncodeAll = true; //set this to true if you want to force encoding of all videos including flv/mp4
