[FFmpeg-user] .wav stream can not play at once

[Soho Soho123]

hi all,

I use ffserver to output a .wav audio stream. Then I use VLC to play
the .wav audio stream with the url "http://localhost:8090/test.wav".
VLC can not play the .wav stream real time. VLC just keep receiving
stream data from ffserver. When I stop ffmpeg, the audio stream is
stop. VLC will play the .wav dat that was recorded earlier.
Does anyone have idea about this issue?
How to fix this issue? the Audio stream should play at once, right?

Thanks!
