Facility Control

We are hoping to use Dashboard to control playback of files from a Black Magic Hyperdeck.

We have downloaded the Panel used in Dashboard U 304. For the most part it seems to be working. The playback buttons work fine, and the "refresh clips" button seems to grab all the filenames without an issue.

But the cuing seems a bit off. It always seems to cue the file before the one you've chosen. For example, if I choose "C.mov" from the dropdown, it will actually cue "B.mov"
If you try to cue the first item in the dropdown, then nothing happens at all, and nothing is cued.

Any idea why?

Thanks

It's possible that there is an off-by-one issue where you are getting back clips with ID starting at 1 instead of 0.
The implementation of this panel is assuming the clip IDs are 0-based.

Another approach would be to have the response builder include the ID returned by the Hyperdeck. I do not have a Hyperdeck handy but, if you replace the code in the listener task with this, you may get better results (added/changed code marked in bold/red). Please report back if this solves your issue.

#DashBoard

Hi James,

Yes that worked perfectly, thanks very much!

#DashBoard

Same problem as above, but pasting James' code fix didn't help.  I'm useless at scripting however, so quite possible I did something wrong.  Pasted bolded lines in Listener task in the BMD Panel. 

Recap - BMD Panel is fully functional except that clips are cued at a -1 position.  eg; clip 002 when cued recalls clip 001.

#DashBoard

Hi all,

Same problem here. Can you explain where the "listener task" is to paste this into? I can't find it.

All the "listener tasks" I look at are currently blank...

Thanks!

#DashBoard

It appears to be at the bottom of the panel:

Hiya

Using this fix (which I needed, as I too had clips cued wrong, and includes the missing + ); I get a bung response here in the debug:

15:37:15:678: end of response

15:37:15:684: making callback with [object Object],[object Object],[object Object],[object Object],[object Object]

15:37:15:691: WE GOT SOMETHING![object Object]

What is the obvious that I've missed?

FYI this is one deck in a grid of 5 of these controller panels. Below is the code from one.

Is there a chance another parseInt() is needed elsewhere?...
