Suppress Duplicate Frames?

I just noticed this in the network settings.  What does this do?  I cannot find any definition what the checkbox does anywhere.  Thanks!

Would you believe it suppresses duplicate frames ... basically if the data to be sent to the controller hasnt changed from the last one sent ... xlights skips sending it. You also need to set the keyframe interval to make sure controllers still see something periodically.

Really only useful for very low end controllers and wifi networks which can easily get swamped.

I suppose this is only from xLights output from a PC and not from a Pi or BBB running FPP?

In settings, I changed "Duplicate frames to suppress" to 10

and then saved a new FSEQ after renaming the old one. They are the same size but I'm curious if they are any different internally? (don't have the tools to verify)

FSEQ doesn't change cause that wouldn't make sense.

Sounds like a player only option to me and would not have any effect on an fseq since xlights would not know what player was going to used.

Jim and Gil, I agree with both of you - but was actually trying to clarify for someone this feature might help.

On the face of it, it reminds me of a DMX-Pro dongle feature that could reduce traffic based on data not changing. The same basis as the "Run-Length-Limited" algorithms used in hard drive storage.

FSEQ files must have data for every frame by definition.

Thanks all!
