If I were doing this, I *wouldn't* change the existing "FileSink" 
implementation, or add anything to the "liveMedia" library.  Instead, I 
would add your new "decoder" code to the Makefile that builds the actual 
*application*.

Suppose, for example, that you wanted to modify the 
"testMPEG1or2VideoReceiver" to use your "decoder".  To do this, I would 
edit "testProgs/Makefile.tail" as follows:
1/ Add
         decoder.$(OBJ)
to the end of the
         MPEG_1OR2_VIDEO_RECEIVER_OBJS =
line, so that it becomes:
         MPEG_1OR2_VIDEO_RECEIVER_OBJS = testMPEG1or2VideoReceiver.$(OBJ) 
decoder.$(OBJ)

2/ Add
         -lm -lz -ldl -lm
to the end of the
         LIBS =
line, so that it becomes
         LIBS =  $(LOCAL_LIBS) $(LIBS_FOR_CONSOLE_APPLICATION) -lm -lz -ldl -lm

3/ Then, in "testMPEG1or2VideoReceiver.cpp", replace "FileSink" with the 
name of your modified class.

4/ Then, in the parent directory, re-run
         genMakefiles <your-os-type>

You should then be able to run "make" in the "testProgs" directory, to 
build your modified version of "testMPEG1or2VideoReceiver".

I hope this helps.
