Video loading triggers "Invalid memory access" error

[0x6e69636f]

Description

When loading some simple video examples from the Video or OpenCV library, Processing triggers an Invalid memory access error on line video = new Movie(this, "transit.mov");

Movie movie;

void setup() {
  size(640, 360);
  background(0);
  // Load and play the video in a loop
  movie = new Movie(this, "transit.mov");
  movie.loop();
}

Expected Behavior

The video should be loaded and the sketch should display it

Current Behavior

Invalid memory access error prevents the sketch to run

Steps to Reproduce

1. Install the Video library in Processing 4
2. Open the example under : Examples > Libraries > Video > Movie > Loop
3. Try to run the sketch

Your Environment

• Processing version: 4.0a1
• Operating System and OS version: Windows 10 Pro, 64 bits, 16GB ram
• Other information: Java JDK 11.0.3

Possible Causes / Solutions

• No idea what's going on
• Works on Processing 3

Thank you for surfacing this @NicolasBD! We will look into it...

Hey there @NicolasBD! I ran into a different issue on Windows (NoClassDefFoundError com.sun.jna.Native) both with https://github.com/processing/processing-video/releases/tag/r6-v2.0-beta4 and https://github.com/processing/processing-video/releases/tag/latest. Just hoping to get lucky, I tried updating JNA and gst1-java-core (1.2.0) but no luck. I'm having some build issues at pack_windows_libs.bat (dlls not found but the folder exists with la and a files). @codeanticode, sorry to pull you in but do you have any suggestions?

[sampottinger]

@codeanticode, just FWIW it does seem to work on mac.

[codeanticode]

@sampottinger ok, sounds like this is time for a new beta of the video library... I will look into it this week (apologies for my slow response).

[sampottinger]

Thanks @codeanticode!

Hello all, any news on this ? Still have the issue with the 4.0.1 on Windows 10

[0x6e69636f]

Hello @sampottinger
Still have this issue on Windows 10 x64 v4.1.1
When I run Processing for the first time, I get this security alert from Windows :

Could it be related ?

[sampottinger]

Hello! I think this is unrelated. See benfry/processing4#25.

[0x6e69636f]

Alright, thanks
But then I have no clue what's causing this error 🤷

[sampottinger]

@codeanticode did you get a chance to dig into this any more?

[codeanticode]

@sampottinger not yet, but was able to get some android work done, so will look at the video library next :-)

[sampottinger]

Awesome thanks!

[codeanticode]

@sampottinger Unfortunately I cannot replicate this issue

@NicolasBD What version of the video library are you using?

[0x6e69636f]

@codeanticode ahh good point, since I made updates from old versions of Processing, I had an old version of the lib installed

But in the tools management interface it still shows the old one, although I updated the new one and it now seems to work

Edit : and I can't remove the old one from there, I get a message "Could not move contribution to backup folder."
I think the new one got installed but it still shows the "update" button on it

[0x6e69636f]

Ok so I just removed the Documents/Processing/libraries/video folder (dunno why I had to restart my computer for that because it seemed to be in use even when I closed Processing), and then I reinstalled the "Video Library for Processing 4" from the Tools manager
I can close the ticket, thanks for your help @codeanticode and @sampottinger

Improvements, if needed, would be in tools / library management between Processing version updates

@NicolasBD thanks for the update! Please open other tickets if you come across new issues :-)
