Created by: Bret Wittmann on 22-04-2011 02:30:50 AM I think there may be a bug when compositing hdmi camera input 1 full screen to output 3 composite. It seems to work intermittently at best. I am using the layout commands to control this by updating a frame. Thanks Bret
Subject: RE: C60 Presenter camera input to composite output Replied by: Jeremy Justin on 08-05-2011 05:59:15 AM Bret sent me some additional information that might help...he has not received a response on this yet. Here it is
"The problem I am having is when I use the xcommands to send HDMI input 1 [presenter camera] to output 3 composite full screen. I am not in a call, but just using the C60 as a switcher/scalar. I am very familiar with the API as I have been using the C90’s as switchers in our rooms for over a year now. I add the layout, create the frame, then update the frame as needed as described in the API for setting up layouts. I am pretty sure this is not a code error as I am getting the proper feedback from the C60 saying frame updated successfully."

"Hi Justin – Here is a picture of the send/receive from the Crestron processor:  As you can see, when I want the Video Conference output to go fullscreen [the first three lines], I unassign the layer from the output. This brings the VTC unit output back to its original state, just like it first appears out of the box. When I want to assign the camera to the preview monitor, or input 1 to output 3 full screen, I assign the layer to output three [lines 8-10], and update the frame with the proper parameters [lines 10-14]. As you can see, the C60 response replies that it has taken the command just fine. Please keep in mind that this happens after I have added the layers and updated the frames as described in the “Video Compositor” section of the how to guide on the API – referenced here: http://developer.tandberg.com/web/guest/howtos/cseries-api/video-compositor Thanks, Bret

Looks like the commands being sent to the codec are the correct ones. Just be aware that you are only able to assign a layout with one full screen frame with x:0 y:0 width:10000 height:10000 to the composite output The API will unfortunately NOT give any warning/errors if a layout not following these rules are assigned.
Could this be the issue in the intermittent cases you are describing?
Cheers, David
Subject: RE: C60 Presenter camera input to composite output Replied by: Bret Wittmann on 03-06-2011 12:12:18 AM Hi David, I am only using one frame on this output. After I create it, I am just updating it with a different input, and then either unassigning or assigning it; So this couldn’t be the issue. Are you able to mock up this problem in your lab over there ? Thanks, Bret
Subject: RE: C60 Presenter camera input to composite output Replied by: David Bruun-Lie on 27-06-2011 11:57:22 AM Bret, sorry for the late followup. I have just tested this myself now in the lab and I get it to work as intended, routing HDMI1 to composite3 on a C60. Can you describe what you mean by "works intermittently"? In which scenarios does it work/not work?
Cheers, David

Subject: RE: C60 Presenter camera input to composite output Replied by: David Bruun-Lie on 28-06-2011 04:00:00 PM Bret, I actually found a bug :-)
The bug is that any layouts that are created with the "layer" set to higher than 1 will not be displayed on the composite output.
So:
The following WILL work:
xcommand Video Layout Add xcommand Video Layout Frame add layoutId:1 positionx:0 positiony:0 width:10000 height:10000 layer:1 border:off videosourcetype:localinput videosourceId:1 xcommand Video Layout assign callId:1 OutputId:3 layoutid:1 (or better: xcommand Video Layout AssignLocalOutput OutputId: 3 layoutId:1)
So will this: xcommand Video Layout Add xcommand Video Layout assign callId:1 OutputId:3 layoutid:1 (or better: xcommand Video Layout AssignLocalOutput OutputId: 3 layoutId:1) xcommand Video Layout Frame add layoutId:1 positionx:0 positiony:0 width:10000 height:10000 layer:5 border:off videosourcetype:localinput videosourceId:1
However, this will fail (and what is what you are doing):
xcommand Video Layout Add xcommand Video Layout Frame add layoutId:1 positionx:0 positiony:0 width:10000 height:10000 layer:5 border:off videosourcetype:localinput videosourceId:1 xcommand Video Layout assign callId:1 OutputId:3 layoutid:1 (or better: xcommand Video Layout AssignLocalOutput OutputId: 3 layoutId:1)
Any special reason why you are using layer:5 ? Solution is to use layer:1
Cheers, David
Subject: RE: C60 Presenter camera input to composite output Replied by: Bret Wittmann on 28-06-2011 07:11:29 PM The API states the following " Layer: The stacking order of the frames (1-5). Must be unique per frame per layout. Layer 5 will be on top."
This is for the instructions for adding a layer using xcommands, so I have been using layer 5 since it has priority - it this wrong ?
Thanks for working on this and finally tracking down this bug. I will go over there today and try this fix... Thanks, Bret

Subject: RE: C60 Presenter camera input to composite output Replied by: Bret Wittmann on 29-06-2011 07:47:42 PM The fix you provided works when I use layer 1 instead of 5. -- Thanks for the help with mocking it up on your end.. Cheers, Bret
