Buggy GigE support + unresponsive matworks

Hi,
I am trying to use a Mako G-234 GigE camera (12 bits, 1216 X 1936 pixels) with the goal to acquire continuous images to disk at 20 fps. ( Win 10 laptop, Matlab R2016).
OK, I took the technical stand of choosing MatLab for this task. Or was it a mistake ?
Up to now, I have been failing to achieve this reportedly "Matworks documented" data acquisition goal of a GigE camera streaming to hard disk. I have explored the various pages Matworks devotes to GigE problems, but with no success.
Here below is the present state of communication between the camera and matlab.
Simple bug, right ? or simple problem easily spotted ?
Matworks, any idea or suggestion ?
Or Matworks not willing to propose anything if a user has not paid for the "support" option ?

"Or Matworks not willing to propose anything if a user has not paid for the "support" option ?"
In this resource, MATLAB Answers, questions are answered by volunteers, some of whom happen to work for Mathworks, but mostly outside volunteers. The volunteers answer if they have time, and if they have an interest, and if they have experience in the topic, and if they happen to notice the question.
I missed your original question because I was rather ill that day. There is also the small problem that I do not have a GigE camera to test with. And apparently it is my turn to do a bunch of house cleaning, and to do some cooking, and to rake up more apples (I already harvested 600 apples this afternoon.)

OK, trying below to give ample time for video initialization. Does not work either...
vid = videoinput('gige', 1, 'Mono12') ;
src = getselectedsource(vid);
src.PacketSize = 9014;
triggerconfig(vid, 'manual');
vid.FramesPerTrigger = 10;
vid.TriggerRepeat = Inf;
start(vid); pause(10); % give MATLAB ample time to initialize the camera
disp('snapshot request now ')
m=getsnapshot(vid);
Result:
snapshot request now
Error using imaqdevice/getsnapshot (line 65) A timeout occurred during GETSNAPSHOT.

Hello Matworks,
it's me again, one month and a half after my initial post; not seen any reaction from you to my post/help request. I feel a bit lonely with my problem, that seems to point to a bug in the Matlab GigE interface.
Okay, I have read a pile of help pages: "deactivate your antivirus, deactivate your firewall"; I did; same bug.
Should I wait for the election of the next pope, to get an eventual answer /help from matworks ?
In the meantime, googling around, I realized that I was not alone with this kind of GigE problem under matlab (and also the unresponsiveness of Matworks about it).
GOOD NEWS: I have discovered ab-soft.com and their GigE sdk "ActiveGigE" *; In a nutshell, it *allows to connect to GigE devices, and in particular FROM WITHIN MATLAB, but NOT using the failing Matlab GigE interface (via the image acquisition toolbox). I was not convinced by the talking. I tried (the sdk is freely downloadable, and the use is free for a month. Also, the tech guy there is very willing to help for eventual problem encountered.
Using this ActiveGigE sdk from ab-soft, (actually simply using a m function), I now can access my GigE camera FROM WITHIN MATLAB, get images, stream to hard disk, etc...
BINGO, IT WORKS FOR ME (WITHOUT MATNOTWORKS GigE...) :-) :-) !
