问题:

I've tried using JMF on a 64 bit environment and 64 bit JDK but to no avail. There isn't a 64 bit jmvfw DLL available for JMF.

My question is: Is there any alternative Media Framework out there that is fully 64 bit or a Java Media Framework 64 bit?

I need it to do camera capturing and video streaming and it has to run on 64 bit environment and JDK.

Thanks

They used to supply an installer .exe, now you have to read the documentation on their website to build the 64 bit windows version yourself, if you want a 64-bit linux build, you can get it at the second URL. Xuggle will let you convert/stream video or audio, I believe it uses a 64-bit compile of ffmpeg with Java as a wrapper around it so that you don't have to think about the ffmpeg command line options.

you can have both 32-bit jre/jdk and 64-bit on the same machine. JMF IS 32-bit. But the java application can still be 64-bit, check out JMStudio code for it and use the 64-bit for the java.awt.Image for example and the 32-bit to bring in the images.

JNI code written in c++ and assembler would be a possible solution if you need it, create custom jar ( java libraries ) and link in .d or .dll files as needed.
