What packages do I need...?

[majix560]

I have Slacko Puppy version 5.7, released Mar 2014.
What packages do I need to install to install these missing libraries?

File /usr/local/jre1.7.0_15/lib/i386/fxavcodecplugin-53.so has these missing library files:
libgstreamer-lite.so libavcodec.so.53 libavformat.so.53
File /usr/local/jre1.7.0_15/lib/i386/libjawt.so has these missing library files:
libmawt.so
File /usr/local/jre1.7.0_15/lib/i386/fxplugins.so has these missing library files:
libgstreamer-lite.so
File /usr/local/jre1.7.0_15/lib/i386/libgstplugins-lite.so has these missing library files:
libgstreamer-lite.so
File /usr/local/jre1.7.0_15/lib/i386/libsunec.so has these missing library files:

I think your post may have got lost in here. Although you have thought about the best place to put it (many don't), it would have been ok to ask in the Slacko thread.
Most of those libs are already there I think, but slightly different (newer) versions - symlinks may work.
The missing ones are libmawt.so libgstreamer-lite.so.
libjava should be in the jre I would think.
If you decide to post again, please say what you are trying to run.

OscarTalks made an sfs of a more recent JRE, maybe it will help:

Not a Java guru sorry, can't help much more.
