Split JavaSE-specific code into separate project #107

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
I'd like to contribute a Android port of this library, but in order to do so I 
need you to first separate all JavaSE-specific code (Swing/SWT) into one 
project and the rest into another project. I propose three projects:

core (classes common to all platforms)
javase (swing/swt)
android (android-specific classes)

Interesting. What mechanism will be used for accessing the native C Gstreamer 
implementation on Android?

JNA, I'm going to port that as well.

There is already a JNA Android port. Check in with the JNA mailing list if 
you're not on it.

Right, I meant I would do the JNA-related porting work. For example, you're 
missing structure.setFieldOrder() in all your classes.

I'm working on a patch but your use of static methods in Gst is killing me.

I need a different "Gst" implementation for Android and JavaSE because the 
variable "nativeClasses" needs to be different for each platform (e.g. you 
cannot load OSXVideoSink). The first thing I did was split the codebase into:

1. Core
2. JavaSE
3. Android

JavaSE and Android define their own Gst class. The problem is that many classes 
reference Gst directly (due to the use of static methods). So now I am forced 
to duplicate these classes in Android and JavaSE modules even though their 
implementation is identical. I'm trying to introduce some Gst "superclass" but 
it's turning into a total disaster.

I could really use your help here.

we can convert Gst into a singleton and reduce the static function, but i don't 
look into how and where Gst functions are called.
