For single binary libraries you need both the path and startup, or you can [declare] them, first -path and then -lib.

I've modified some abstractions created by @60hz for prototyping fast with ofelia (BTW, thanks a million for your abstractions they're great! And of course a million thanks to @cuinjune for creating Ofelia!). Things seem to work OK, but there's this happening. I have the following patch (I've changed the names from [gl.draw] to [ofelia.draw] for this and other abstractions)

[ofelia.draw]
|
[ofelia.cube]

and I see a white cube in the Ofelia window. Then I make the following connections:

[ofelia.draw]
|
[ofelia.movie]
|
[ofelia.cube]

and I get a video playing in the same cube. Till now everything is fine. But if I go back to the first patch, I don't get a white cube anymore but a still from the video file from [ofelia.movie]. Here are the scripts of the abstractions (almost identical to @60hz abstractions):
[ofelia.draw] (I'm returning ofColor because I want to have all abstractions output pointers and not bangs, maybe there's a better solution for this):

ofelia d draw$0;
local c = ofCanvas(this);
local args = c:getArgs();
local depth = true;
local screenwidth;
local screenheigh;
local widthHeigh;
;
function M.new();
  if args[2] == nil then depth = true;
  else;
  M.depth(args[2]);
  end;
  if ofWindow.exists then;
  screenwidth = ofGetWidth();
  screenheight = ofGetHeight();
  end;
end;
;
function M.screensize(list);
  screenwidth, screenheight = list[1], list[2];
end;
;
function M.depth(string);
  if string == "3d" then;
  depth = true;
  else;
  depth = false;
  end;
end;
function M.bang();
  ofSetDepthTest(depth);
  ofTranslate(screenwidth*0.5, screenheight*0.5);
  return ofColor(255, 255, 255);
end;

[ofelia.movie]:

ofelia d -c17 videoplayer-$0;
local canvas = ofCanvas(this);
local args = canvas:getArgs();
local videoplayer = ofVideoPlayer();
local filename, start, loop = args[1], args[2], args[3];
local loaded = 0;
;
function M.new();
  ofWindow.addListener("setup", this);
  if args[1] == nil then print("No file found");
  else M.open(filename);
  end;
  if args[2] == 1 then M.play();
  end;
  if args[3] == nil then loop = 0;
  end;
end;
;
function M.free();
  ofWindow.removeListener("setup", this);
end;
;
function M.setup();
  M.open(filename);
end;
;
function M.open(string);
  if ofWindow.exists then;
    videoplayer:close();
    videoplayer:load(string);
    if (videoplayer:isLoaded()) then;
    print("loaded " .. string);
    videoplayer:update();
    end;
  end;
end;
function M.url(string);
  if ofWindow.exists then;
    videoplayer:close();
    videoplayer:load(string);
    if (videoplayer:isLoaded()) then;
      print("loaded " .. string);
      videoplayer:update();
    end;
  end;
end;
function M.play() videoplayer:play() end;
function M.stop() videoplayer:stop() end;
function M.pause() videoplayer:setPaused(true) end;
function M.speed(float) videoplayer:setSpeed(float) end;
function M.frame(float) videoplayer:setFrame(float) end;
function M.volume(float) videoplayer:setVolume(float) end;
function M.loop(float);
  if float == 0 then videoplayer:setLoopState(OF_LOOP_NONE);
  elseif float == 1 then videoplayer:setLoopState(OF_LOOP_NORMAL);
  elseif float == 2 then videoplayer:setLoopState(OF_LOOP_PALINDROME);
  end;
end;
function M.get()
  return ofTable (videoplayer, videoplayer:isLoaded(), videoplayer:isPlaying(), videoplayer:getCurrentFrame(), videoplayer:getTotalNumFrames(), videoplayer:getWidth(), videoplayer:getHeight());
end;
;
function M.pointer(p);
  videoplayer:update();
  videoplayer:bind();
  return videoplayer;
end;
function M.bang();
  videoplayer:update();
  videoplayer:bind();
  return videoplayer;
end;

Inside [ofelia.movie] there's this patch:

[ofelia d movie_script] <- this is the ofelia object that loads the script above
|
[t a a]
|    |
|    [outlet]
|
[ofelia d videoplayer_unbind;] <- this is one object
[function M.pointer(p);      ]
[p:unbind;                   ]
[end;                        ]

and this is [ofelia.cube]:

ofelia d $0-box;
local c = ofCanvas(this);
local args = c:getArgs();
local width, height, depth, resw, resh, resd, drawmode, strokeweight = args[1], args[2], args[3], args[4], args[5], args[6], args[7], args[8];
local position, orientation, scale = ofVec3f(0, 0, 0), ofVec3f(0, 0, 0), ofVec3f(1, 1, 1);
;
function M.new();
  ofWindow.addListener("setup", this);
  if args[1] == nil then width = 100 end;
  if args[2] == nil then height = 100 end;
  if args[3] == nil then depth = 100 end;
  if args[4] == nil then resw = 5 end;
  if args[5] == nil then resh = 5 end;
  if args[6] == nil then resd = 5 end;
  if args[7] == nil then drawmode = "fill" end;
  if args[8] == nil then strokeweight = 1 end;
  M.setup();
end;
;
function M.free();
  ofWindow.removeListener("setup", this)
end;
;
function M.setup();
  box$0 = ofBoxPrimitive();
end;
;
function M.resw(float) resw = float end;
function M.resh(float) resh = float end;
function M.resd(float) resd = float end;
function M.width(float) width = float end;
function M.height(float) height = float end;
function M.depth(float) depth = float end;
function M.draw(string) drawmode = string end;
function M.stroke(float) strokeweight = float end;
function M.position(list) position = ofVec3f(list[1], list[2], list[3]) end;
function M.orientation(list) orientation = ofVec3f(list[1], list[2], list[3]) end;
function M.scale(list) scale = ofVec3f(list[1], list[2], list[3]) end;
;
function M.pointer(p);
  ofSetLineWidth(strokeweight);
  box$0:setPosition (position:vec3());
  box$0:setOrientation (orientation:vec3());
  box$0:setScale (scale:vec3());
  box$0:set(width, height, depth, math.abs(resw), math.abs(resh), math.abs(resd));
  if drawmode == "fill" then box$0:drawFaces() end;
  if drawmode == "point" then box$0:drawVertices() end;
  if drawmode == "line" then box$0:drawWireframe() end;
  return p;
end;
function M.bang();
  ofSetLineWidth(strokeweight);
  box$0:setPosition (position:vec3());
  box$0:setOrientation (orientation:vec3());
  box$0:setScale (scale:vec3());
  box$0:set(width, height, depth, math.abs(resw), math.abs(resh), math.abs(resd));
  if drawmode == "fill" then box$0:drawFaces() end;
  if drawmode == "point" then box$0:drawVertices() end;
  if drawmode == "line" then box$0:drawWireframe() end;
  return anything;
end;

This is a bit too much information but I think it's necessary if anyone can help. There's probably stuff I'm ignorant of. @cuinjune any hints?

right inlet of [symbol].

@ricky TBH, I don't know. Perhaps you can skip the sleep part and just type the pd launching command right after "reboot". Your Pi is being shut down and powered up again every day or something like this? It sounds strange as to why this is happening, and even though Linux is my OS, I'm no guru by any means. Perhaps the Pd list is the place to find the answer to this.

You need something to drive this. In the code chunks of the link you provided, t is a variable that increments by one on every loop of the code. Perhaps feed a [phasor~] multiplied by some value to an [expr~] which will run this code. Be careful to check the output and normalize it before sending it to [dac~], no idea what the function above produces.

Mind that the videos in the link produce 8-bit audio. If you want to achieve something similar you should probably multiply [phasor~] by 255 and truncate the decimal part, in [expr~ int($v1)], or something like this.

Katja Vetter created a vanilla abstraction that simulates [freeverb~]. I can only find a fork by Derek Kwan, but it's the same abstraction. It's here https://github.com/derekxkwan/pd-vfreeverb

I'm just using the latest Raspberry Pi OS in one Pi and the one before that (can't remember the code name now) on another Pi. I'm always using the Lite version though, don't know if that has anything to do with it.

This sounds strange as I'm using the Pi all the time with Pd, and never get these crushes. Are you guys sure it's not the patch causing the crash? One thing that might work is to launch Pd without loadbangs, by typing this in a terminal pd -noloadbang
Maybe you want to add the -stderr and/or the -verbose flags so that Pd prints its output to the terminal and gives more information as to what it's trying to do. In case of a crash, the log will remain in the terminal window so you can inspect it.
Disabling loadbangs and checking Pd's output might give some hints.

You can also check IOhannes' [aconnect] external object, it works great!

how about [list split]? Although you'll might have a problem as Pd doesn't like the curly bracket. Don't really know...

If [list split] works and you don't really know where "lon" and "lat" are in your list, you can use [list fromsymbol] to convert the strings to their ASCII characters and compare with a message "symbol lon" passed through another [list fromsymbol] via [list-abs/list-compare] (or just make your own list comparison algorithm).
