That's the first version I tried and it just hangs. Doesn't stream anything, nor return error. After about 2 weeks of researching why it does that I found the version with the mplayer, witch works.The entire goals is to stream with vlc from a computer to a server and then again so that step can not be bypassed. If you can tell me how to do it so the ffmpeg works directly with the stream without mplayer i'd be gladly to skip that step.
I have a setup that uses VLC to grab an 18.3Mbps HDV 720p60 feed over firewire from my camera to a winXP box. This is sent using http streaming over gigE from the XP box which has the firewire card to an ubuntu box which has ffmpeg and ffserver. It works.
In my case, HDV is already mpeg2 transport stream, so VLC does no transcoding, just dumps it to http. My ffmpeg line is something like ffmpeg -i http://blahblahblah:8080/live http://localhost:8090/feed1.ffm
Seems that the two big differences are (1) you're trying to do some processing (-r 24) in your ffmpeg line. I don't think that you can do that. Also I use http rather than rtp. You might changing one or both of these.
Another possible difference is that my ffserver stream is also mpeg2 at 18.3Mbps. Thus, in theory, ffmpeg doesn't have to transcode, either (though in practice it does since ffserver has no way of knowing that the incoming stream is already in the right format). So it could also be a problem with the format of your stream coming from VLC. You don't say what the output format of VLC is, you might try using something different as the output of VLC to see if that helps. I would naturally suggest getting VLC to transcode to mpeg2 transport since I know that works....
You could also try streaming from ffserver in a different format, although, since it does work with the mplayer interposed that's probably not the issue.
If it's any consolation, it took me about 2 months to figure out exactly how to make all this stuff work right, and even now I'm still working out bugs. In case you're interested, my goal is to capture our entire morning worship service in HD, while also streaming the sermon portion of it, that occurs at some unknown time in the middle, to a remote location in quasi-real time just with an arbitrary time delay.
