6 years ago I need more detail. Can you write a small program which uses openCV to read an image with cv2.imread and display it with cv2.imshow followed by cv2.waitKey(0). If that works the simulator should work.

6 years ago Dear Brian. Yes openCV reads and show a picture:
import cv2
img = cv2.imread('messi.jpg', 0)
cv2.imshow('image', img) cv2.waitKey(0)
But this not works why because the opencv version? It is another way to fix this problem? How can I start a simulator panel example in python? Thank you for your help.

6 years ago I have added the openCV constant values (as comments) in Constants.py and changed ImageCache.py to use my definitions. You'll experience similar problems trying to use HERSHEY fonts unless you download the new Constants.py plus a couple of other other updates to avoid your problem.
According to my research on the internet, the problem you are seeing with cv2.XXX constants not being recognised is (possibly) due to python picking up the wrong openCv library (previous V2 leftovers?). If you built openCV on your PC you will find the library python needs in the build/python folder. I had to copy that to my python site-packages folder (save the old one if it exists). If you installed openCV using PIP then I don't know what version you got but cv2.version will tell you.

6 years ago Dear Brian. My opencv version is 3.4.0.12 >= 3.0. I set the constants python file with the constants numbers but gives me an error when compile MatrixTest.py file with te compiler python 2.7.13. How can I fix this error please to run the simulator? Thank you for your help.
C:\Python27\python.exe C:/Users/User/Desktop/rpi-rgb-led-matrix-animator/Simulator/MatrixTest.py RGBMatrix: Not recording video RGBMatrix.run() starting the simulator window. RGBMatrix.run() setting up window failed (keyboard key stuck?). Image display took 0.048910
BNNorman

6 years ago It isn’t really an error – the MatrixTest.py just opens a simulator window – it does nothing with it except display the red box image and wait for you to press a key.
It thinks a key is already pressed. Possibly it need more time on your machine.
If you look at lines 173 to 176 in RGBMatrix.py you will see the error message. It is saying waitKey(1) returned a value other than 255 (-1) after waiting 1ms. This is just to allow the openCV imshow() code to display the image.
255 means it timed out waiting for a key press. Any other value indicates it thinks a key is pressed before it enters the “while self.running” loop.
This explains waitKey :-
https://docs.opencv.org/2.4/modules/highgui/doc/user_interface.html?highlight=waitkey#waitkey
If you print the value of r it will tell you which key openCV thinks is pressed.
You can increase the delay from 1 to any number you like. Possibly your system hasn’t created the window in time and you need to increase the value on line 173 – did the window appear at all? If not then try increasing the delay slightly.

6 years ago Dear Brian. For the question:
Possibly your system hasn’t created the window in time and you need to increase the value on line 173 – did the window appear at all? - The windows appears for a second and disappears after. I will increase the delay to see what happens. Thank you for your atention.

6 years ago I’ve just uploaded a patched RGBMatrix.py – apparently some systems don’t return -1 (255) on timeout. I have added masking to waitKey() which might fix your problem – the patch works on my machine (it worked ok anyway).
Basically do this:-
r=0xFF & waitKey(1) on line 173
and also in the while loop – I’ve closed PyCharm so I can’t say which line it was – you could just download the updated RGBMatrix.py.
Let me know how you get on.

6 years ago You haven’t told me what the errors are. Grab a screen shot of all the messages, please.
Fourcc isn’t mine, I assume you want to record the video in a different format –I’m guessing (tired and going to bed) it should be :-
def startVideo(self,fname): self.video = cv2.VideoWriter_fourcc(*'DIVX')
if you can provide the full error messages I’ll reply in the morning.

6 years ago I made an error in my last email – I should have looked at my code again first.
This may be the problem – (you didn’t send me the actual error message so I was guessing) – I’m guessing it’s the same problem you had with openCV on your machine
Try this…
fourcc=cv2.cv.CV_FOURCC(*'DIVX')
it’s doesn’t give an error on my system.
Instead of DIVX you might also specify XVID if it’s the DIVX encoder that’s the problem.
Let me know if this fixes your problem – if so I’ll add something to Constants.py.

6 years ago Looking at where this error originated it seems that the PoissonLib might have generated Nan values.
Since I didn’t write the original code I don’t know why it is possible. However, I’ve added code to filter the samples and remove any NaN values.
If the filtering results in an empty list you should see this message
"PoissonLib() failed to generate any samples."
I have run the code in a loop 100x and it hasn’t once failed.
I have pushed the new PoissonLib.py to Github – it will be easier for you to download that rather than me explain where to add the extra 8 lines of code.
Regards
Brian

6 years ago I am able to repeat this now. I still don’t understand why it happens. The values of x, y and color are correct and they are/contain integers
There is a simple workaround. I have put a try-except around the offending code to ignore the error – it doesn’t affect the Twinkle animation – but more importantly the animation continues to run.
I have pushed an updated NumpyImage.py to Github – I suggest you download it.

6 years ago This code drives the panel directly through the hzeller library. It has nothing to do with the simulator. It needs a loop to keep the panel refreshed. You need to call SwapOnVSync. Look at zellers python examples for ideas.

6 years ago I am unable to replicate this – though I can think of a workaround for it, but before I add extra code could you please insert the following code before line 489 ,at start of NumpyImage.setPixel() method then let me know what is printed please.
print "type(x)=", type(x), "type(y)=", type(y),"type(color)=",type(color)
I get the following showing that x and y are both integers and color is a tuple e.g. (r,g,b,a)
type(x)= <type 'int'> type(y)= <type 'int'> type(color)= <type 'tuple'>

6 years ago There are two errors in there. The main one causing the AssertionError I have just fixed getPixel() wasn’t returning a tuple.
This error will take more investigation.

I have recently uploaded a new version of UtilLib.py would be worth downloading it to see if it still happens.

Dear Brian. I get this error when I test the PanelDemo.py file. At start of NumpyImage.setPixel() method the result of the print was:
type(x)= <type 'int'> type(y)= <type 'int'> type(color)= <type 'numpy.ndarray'>
How can fix please? Thank you so much for your help my friend.

6 years ago Dear Brian. Yes I have the recently UtiLib.py file and I test the PanelDemo.py and have the same errors. I wait for your help my friend when you can. Thank you for your kindly attention.

6 years ago Dear Brian. Sorry for my mistake. The test that gives 2 errors was made in the file SimulatorCheck.py. Sorry again my friend.

6 years ago Yes I can see that but I uploaded a new NumpyImage.py tonight because that was causing it.

6 years ago Dear Brian. Thank you my friend. The SimulatorCheck.py is working but have the warning UtilLib.alphaBlend() images not the same shape. Ignored. fg (64, 63, 4) bg (63, 63, 4) with the new file UtiLib.py. How can I use multicast UDP using your simulator? Thank you for your help Dear friend.

6 years ago Good stuff.
I think the 'images not same shape' is still an issue in UtilLib.py which I need to work on. It's to do with the calculation of the slice of the foreground image which overlaps the background. Getting the background overlap region is the easy bit but the foreground slice can slide within the foreground image and I think it's that calculation which may be 1 pixel wrong.
UDP:
Check this out: https://stackoverflow.com/questions/22878625/receiving-broadcast-packets-in-python
In RGBMatrix you would add code to send the video frames (self.frameBuffer) at the end of the setImage() method (After line 155). I've not played with UDP so can't help more. Sounds interesting though, what do you plan to do?

6 years ago Dear Brian. Thank you for your attention my friend. I want to use UDP multicast to send the same pixels/data at the same time to a pair of panels instead of using the same entrance from an adafruit hat with a flat cable for both, instead using hardware stuff solve using by software. How can do by only using software? Thank you for your help Dear friend.
I'd just like to says thanks again for your library and the active driver board, which I bought from OSH Park.
You said you like to see what people are doing with your code etc so take a look at this (about 7 minutes long):-
https://www.youtube.com/watch?v=hF6wfx8zTg0&feature=youtu.be
It's a bunch of graphics and image animations running on a hub75 panel 64x64 pixels and driven from a Pi3. I have buffered output to the Panel , using numpy images, in order to handle an alpha channel. And no, I haven't driven a bigger panel (can't afford it).
The code is available here if anyone is interested:-
