Uplink with ffmpeg: playback with ffplay, vlc and rtmpdump fails

[GoogleCodeExporter]

I uplink using ffmpeg...
ffmpeg -i somevideo.mp4 -re -vcodec copy -acodec copy -f flv 
rtmp://localhost/live/livestream

In this case the video is H264/MP3 and known to work with other live rtmp 
streaming software e.g. Wowza and rtmpd.

If I try to connect to the stream using VLC using...
vlc -vvv rtmp://localhost/live/livestream

I get the following error report...

If I open with ffplay...
ffplay rtmp://localhost/live/livestream

I get the following error report...

Closing connection: NetStream.Play.StreamNotFound
rtmp://localhost/live/livestream: Operation not permitted

If I connect using rtmpdump piped into ffplay...
rtmpdump -r rtmp://localhost/live/livestream -q -o - -v | ffplay -

I get only sound, no picture, and the following error report...
