You must have been using the player 3 (FLV Player maxi). It is not included since v2.7.1 due to the license issue. The player 4 (Flowplayer 4 ) is used if the player 3 does not exist. But the player 4 does not show the controls when flash image is used.
Starting from V2.7.1 , FLV Player Maxi is no longer included by default because it is licensed under non GPL compatible licenses (CC, MPL 1.1). But you can still download and unzip it manually under your Hana FLV Player plugin path.
You need to download the zip file from http://flv-player.net/players/maxi/download/ and unzip into the hana-flv-player plugin folder. The unzipped folder name must be 'template_maxi_1.6.0'.
Or I recommend you to use the player 5.( MediaElement.js) .
