Script/Plug-In Trigger on Data

[Bwinter]

Is it possible to trigger action (ie., GPIO pin) based on whether or not any type of pixel-data is being output (whether it being a playlist playing, a sequence playing, or even display-testing being output)?

I know I can toggle GPIO pins at the start/end of a playlist, by adding the GPIO function to the playlist itself.  But that doesn't handle instances for playing a single sequence or display-testing.

Is there something that can be done (script or plug-in or other?) that can do this automatically anytime something is playing (playlist/sequence/test-data)?

No

It doesn't do exactly what you want, but here's a bash script I use to determine if something is playing.  You can add your code inside the case statements.  Maybe you can do something with this?

#!/bin/sh
############################################################################
#
# Run scripts based on whether or not FPP is currently playing a sequence of some sort.                        
#
############################################################################

# Get our current status
STATUS=$(/opt/fpp/src/fpp -s | cut -d',' -f2)

# Act on the current status
case $STATUS in
	# IDLE
	0)
                echo "Not playing."
		;;
	# PLAYING
	1)
                echo "Playing."
		;;
	# STOPPING GRACEFULLY
	*)
		echo "Unknown status."

You could use the PLAYLIST_STARTED/PLAYLIST_STOPPED/SEQUENCE_STARTED/SEQUENCE_STOPPED Command Presets and turn on/off a GPIO in the command.

Correct—that's what I currently do for playlists (and it works fine, as long as I remember to add the command at the start/end of each playlist).

However, it doesn't work when playing a single song/sequence (or anything from display-testing).

So I'm looking for a something a little higher-level, that can be globally set for anytime something is playing

You misunderstand Chris's suggestion.

Go into the command preset page, in the preset name type PLAYLIST_STOPPED etc, then define what the action is you want to happen.

Ah thanks--I see it now. Seems to be working exactly the way I need!

I've never fully understood what that section was used for, but now it makes perfect sense.

it doesn't cover all of your use cases (eg display testing) but it gets closer than adding stuff to playlists.

I did notice that, but I rarely use display testing...so at least having it function for playlist and sequences is sufficient.

My intended use is for a RPI PiCape situation, where I'm operating in Master/Remote mode.  If I set these commands in the Master, would checking the "multi sync" button also trigger the GPIO pins in all the remotes?  Or if not, is there a way to do that?

I would bet that you would need to use the "run a remote script" command to do that and then install the GPIO ON and OFF scripts on your remotes to set the desired GPIO's.

Not sure, you'd need to test it.

Worst cast call a remote trigger preset command thing.
