One possible solution woul be JavaCPP: http://code.google.com/p/javacpp/
Its author - Samuel Audet - has already wrote a Java wrapper for 
libavcodec and libavformat, named as avcodec.java and avaformat.java 
respectively. You can find those in the JavaCV package:
http://code.google.com/p/javacv/source/browse/src/main/java/com/googlecode/javacv/cpp/avcodec.java?r=5bbb841a1d9b03328ad0c3dbc723ad6903220d62
http://code.google.com/p/javacv/source/browse/src/main/java/com/googlecode/javacv/cpp/avformat.java?r=5bbb841a1d9b03328ad0c3dbc723ad6903220d62

You probably need to access libavresample. JavaCV doesn't provide any 
wrapper for that but you could easily derive your own by looking at the 
above mentioned sources.

I've gathered some experience in working with JavaCPP by creating a 
cross-platform java wrapper for Google's Tesseract OCR engine. Don't 
hesitate to contact me if you need some further help...
