Single or Multiple Video-Ouput on Decklink-Cards developed with Delphi

We need a Software, including all needed Sources which i able to send out HD-Videos to specified Decklink-Output. We will create some small playlists to playout those playlists. If we could get an internal preview of videos it would be great. If we would have to pay extra for 3rd-party-licenses (like FFVCL) we can talk about. In detail we want to have a Delphi-Project (XE2 - XE5) which is using the Blackmagic-SDK. We need to be able to select the possible Output-channel and play one or more Videos on 1 or more channels. For example at Decklink Quad 2 are 8 possible single-output. In this case it would be great if we could playout on all channels a video. The videos must be able to start und ad stop independendly. This is not a php, Java, C or C#-Project. We do not need any offers for websites. Please contact me only if you are able to deliver things we need from above.
