I would like to broadcast 24/7 via wowza streaming cloud to facebook an IP camera and mix on top of it a static audio track from a file.

How could I achieve that?

The audio and video would need to be sent together prior to arriving to the Wowza Streaming Cloud transcoders. We do “mix” sources in Cloud. There is an Engine option to do this using the AVMix module:
