Also commit the JNA interface to the C library interface code
Add a parameter to change the duration that each frame is used for (to support slow encoding)
Make the output file be customizable
Integrate the new encoder, replacing the h264 encoder. Hack the framerate to be 8fps, because the variable fps isn't working
Actually, push the framerate setting out into Java land
Covert all the extensions to .webm, because web browsers seem to like it better
