You can even use ffplay; it is generally able to play RTSP URLs. But I 
guess the best choice for this kind of things is vlc.

The _real_ problem is that on rtsp:// url with a .flv file does not 
really make too much sense. You have to use audio and video which are 
supported by RTPS / RTP (a .mpg file should be ok. If you use ffserver, 
you have to put mpeg1 video in it, because libavformat does not support 
mpeg2video over RTP).

You have to compile it with live555 libraries enabled.

I suspect DSS can stream MPEG{1,2,4}, H.264, and maybe H.263. And AAC 
audio, of course. FLV is not cited in any RFC, so it cannot be supported 
in any standard way.

This is supported by ffserver. I never tried a live feed, but it is 
possible to make it work when streaming from a file.

This should work (in theory), but I never tried.

This cannot be streamed over RTSP / RTP.
