Issue exporting an GSVideo appllication

in Contributed Library Questions • 2 years ago

Hey,

I'm trying to export a processing application that uses GSVideo as a windows executable. However when I run the application the whole thing just hangs without any notification as to why. I've managed to figure out that its something to do with the GSVideo library and the gstreamer dlls required by the app. I've copied over the gstreamer folder to the application folder as mentioned here http://codeanticode.wordpress.com/2009/07/26/fresh-releases-of-gsvideo-and-glgraphics/ . Still no joy though, the application still hangs.

I can also recreate this by trying to export the 'Loop' sketch in the GSVideo examples. Runs fine when testing from the PDE, but as soon as I export as a windows app, it doesnt work. Even if I copy over the gstreamer directory.

Is there something I'm missing here? And can anybody replicate this bug on windows 7.

Could you try starting the exported application from the command line and report any error messages you get there? Thanks!

I have the same problem on a Mac running Snowleopard, Processing 1.5.1, GSVideo 0.9 and GLGraphics-20110612.

This is the error message I get when running the app from a terminal:

Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: Unable to load library 'gstreamer-0.10': dlopen(libgstreamer-0.10.dylib, 9): image not found

Just to make sure I'm doing this right: I run the App it by doing:

cd MovieCycler.app/Contents/MacOS
./JavaApplicationStub

I've tried copying the libraries to the inside of the app, but even if that's what I'm supposed to do I'm obviously putting it in the wrong directories or subdirectories.

Thanks for reportint. I just tested on my laptop, also using Snow Leopard, and the gstreamer libraries are not included in the app bundle... It worked before for sure. I will look into this.

In the meantime, any suggestion what files to copy where manually? I'm not really a Mac user myself, I tried to program a simple app for a friend ;)

Hello,

I have the same problem on win 7 64-bit. I used the Loop example from GSVideo.

The folder gstreamer/win with all the dlls was copied manually to D:/Setups/Processing-1.5.1/modes/java/libraries/GSVideo/examples/Movie/Loop/application.windows

But that didn't change anything.

Output of cmd is below.

D:\Setups\Processing-1.5.1\modes\java\libraries\GSVideo\examples\Movie\Loop\appl

ication.windows\lib>java -cp Loop.jar;core.jar;gstreamer-java.jar;GSVideo.jar;jn

@marklundin and @jobleonard: I found a workaround for windows. With the corresponding paths it should work on mac too.

Put the following in void setup() :
GSVideo.localGStreamerPath = sketchPath+"/gstreamer/win";
This variable is empty by default.
Export your application.
Copy the folder _ PROCESSING_LIBRARIES_FOLDER_/GSVideo/library/gstreamer
to the folder of your exported application.
(Now the app folder should include the following folders: source, lib and gstreamer)
Run your app and have fun.

Thank you very much for this tip :)
But I have another problem with present mode : if I export for win 7 (processing 1.5) it works, but if I export it with Present mode, videos does not appear.
I tried with the fullscreen lib, if I press a key to switch in fullscreen mode (same resolution), I can hear my movie but not see it.
Any idea ? Thanks !

Hi,

The workaround worked for me but i had to add a dot : GSVideo.localGStreamerPath = sketchPath+" ./gstreamer/win";

thanks
