Comment (by kyl416):

 If you aren't familiar with MediaTomb, basically this is called by a
 subprocess within MediaTomb, %in is replaced with the input, and %out goes
 to a temp file that the client accesses.

 Output of a working build:
 -i %in -b 4096k -maxrate 4096k -minrate 4096k -bufsize 2458k -bt 380k
 -threads 2 -ar 48000 -ab 160k -acodec mp2 -f dvd -y %out
