FFMPEG command line options to produce HLS stream video output

For a project I need to stream H264 video using HLS so that it can be natively supported by iPhone/iPad IOS and hopefully Android too. We are using FFMPEG to capture a window content and encode it in H264 in real time using GPU. We cannot simply save it to a file and make it available through web server, so we need to configure the FFMPEG output to produce the HLS stream directly. No multicast is needed as we only expect one client per stream. Trying out all the FFMPEG parameter combinations until I put it to work seems a bit stupid and prefer to request help from experts in this widely used tool.
