OSX + GSvideo cannot make applications that runs

in Contributed Library Questions • 2 years ago

I am on 10.6.8 with the latest stable Processing and (32-bit) GSvideo. My script works from within Processing (video capture and processing, sound output), but when I export an application and run it separately, there is no video, and the Console returns the following error:

This is similar to a problem here: http://forum.processing.org/topic/problems-with-gsvideo-on-a-mac-unsatisfiedlinkerror-gstreamer-0-10 but it's from well over a year ago, and all indication was that the dependency issue was fixed.

I would like, eventually, to run this program at startup, but I need a standalone application in order to do that. Does anyone know what the problem could be?

I ended up having to manually copy the gstreamer folder from the lib into the exported file. I was working on a pc, so it was in an application folder. on a mac you may have to right-click and show package contents to access the place to drop it into.

Hope this gets you started.

good luck!

yup, the current export mechanism in 1.5.1 doesn't work anymore with gsvideo, so you need to copy the gstreamer libs manually. As ak pointed out:

1) On windows, copy the gstreamer folder from GSVideo/library into the exported app folder.

2) On OSX, show package contents and copy gstreamer into Contents/Resources/Java

I'll have to wait until I get back on the production machine, but that sounds like it'll work. Thanks!

I'm afraid that doesn't work.

1) Exported my sketch as an application. It shows up in ~/Documents/Processing/myproject/application.macosx/myproject

2) Did a "Show Package Contents" on that "myproject"

3) Copied ~/Documents/Processing/libraries/GSVideo/library/gstreamer directory into myproject/Contents/Resources/Java/

The application runs, opens a window of the proper size (it didn't do this before), but no video shows up, and no sound is played. And the CPU doesn't heat up. =0)

I thought maybe is was the extended attributes, so I went through all of the directories in "gstreamer" and did a "xattr -d com.apple.quarantine *" on them. No help.

It probably can't find your movie. Have you checked the Console? What does it say?

A lot of people (me included) have had problems with the data-folder not being exported correctly into the .jar file.

right, this is an important point when running a movie playback sketch as an exported application, as gsvideo won't be able to load any media from inside a jar file.

Do something like this in the sketch code, before exporting:

movie = new GSMovie(this, sketchPath("data/station.mov"));

and then copy movie file to application.{macosx,windows,linux}/data.

I don't load in any movies, only sound files. So I suppose I can use the same syntax in my GSPlayer line?

I forgot about Console. I typically only use Linux, and having a console open and available is just second nature. Console shows that it can't find my first audio file. I should have looked there first.

Re: OSX + GSvideo cannot make applications that runs

yes, I think you should use a similar syntax to play audio files from the exported app.

Okay, thanks tons. Here's what wound up working:

crowd = new GSPlayer(this,sketchPath("../data/crowd.wav"),GSVideo.AUDIO);

But that only works when I export the application. For editing and running from within the Processing IDE, I have to remove the preceding "../" from all the file names. I hope this helps someone else.

Unrelated, but I also learned that Processing/GSVideo can use more than 2 channels of audio: just load in multi-channel audio files and play them normally. The external USB audio interface recognized the multichannel output from Processing and I was able to route the channels to more than two speakers.
