Use the following parameters:

Video codec	H264 Baseline
Key frame period	2880 ms
Frame rate	custom @ 25 fps

Sampling rate	48KHz or 32 KHz

If you plan on encoding live streams with Expression Encoder 4 you also have to configure what you return as the Server HTTP response Header. The default is Full which sends information about the OS-type and compiled in modules.

In your /etc/apache2/conf.d/security:

ServerTokens Full
