(Instead of libfdk_aac, you can use libfaac. The original source did so. It appears that libfdk_aac is a superior replacement.)
Note that the above adds "-movflags faststart" to the mp4 creation. This causes a second pass on the file (slow, sadly) that moves the metadata to the start of the file, making it faster for a web browser to seek into the middle of the file. Instead of "-movflags faststart" you can use the tool qt-faststart.
