Is there a plugin or something that can send a command to an external controller for screen masking?

[1971camaroguy 32]

Trying to automate my theater CIW theater screen, and building a masking system.

I'm running emby premiere on a dedicated windows machine, and was wondering if there was something out there that can send a command to my external controllers for the automation based on movie screen aspect ratio?

I am hoping there is a way to do it within emby as that's what I use to play back movies to an nvdia shield pro.

Thanks in advance

Hi. There is webhooks but it is not going to have any knowledge of aspect ratio.

If you use the Android TV app, the zoom modes are remembered for a particular item but that isn't going to automatically trigger your mask.  You actually have a CIW setup?  That is basically how all TVs are but projector setups are usually Constant Height (that's what mine is but I use a lens).

Yeah mine is an Optma UHD51A, it does have alexa....but it doesn't have lens memory or the zoom like your projector.

I might be bakwards on the terminology the the height always stays the same, just with 2:40 or 2:35 movies I have the bars at the top and bottom. The screen is a 110" accoustically transparent so my center in behind the screen. 

I've got four Limoss 450626 Model MD141-27-L1-157-333 actuators (used in recliners) that have a mounting base and would work perfect to move masking panels. It also has a up and down switch I am going to wire in to manual move them, but it would be nice to have something automated.

If it is a 1.85 screen then it is constant width - just like a normal TV.  Many projector setups are with 2.35 screens which are constant height just like the real cinema.  This keeps the image the same actual size regardless of aspect ratio.

In any case, no, I don't think we have anything at this point that would allow you to automate this.

Write code that runs a ffmpeg command to get the ratio numbers you need and send it to your screen controller.

Then call the file or function either from the event of starting a video or maybe with a custom button controller window on it's own HTML page.  Seems like it's a lot of work to automat something you can just look up and enter yourself.  If it works, it would be nice to see a solution posted back.

The ffmpeg part will only be effective if his videos are actually cropped to the proper resolution, however.

Ok, I switched gears a bit.

Doing some research, I decided to sell my old projector and picked up an Epson projector with lens memory. Also am selling my 16:9 110" screen and bought a 2:35 127" screen.

Going to set lens memory to remember the 16:9 setting and have black bars on the sides and a 2:35 / 2:40 setting to zoom that format fit the screen (with black bars outside of the coverage area).

I might make some press in side black out panels for 4:3 and 16:9 if that bothers me too much.

No motors, no headache, and will be a cleaner set-up once I build the false wall to put my speakers behind (it's an accoustically transparent screen)
