[FFmpeg-user] HELP!HELP! ffmpeg+ffserver stability issue via 127.0.0.1 http post

[Soho Soho123]

Hi All,

When I try to setup a stream server with ffmpeg+ ffserver.
the problem I got is :
ffmpeg use tcp to connect ffserver. then ffmpeg use http post to send video
data to ffserver via loopback.

the source of video data is from usb webcam,
ffmpeg capture video then post to ffserver via tcp socket through loopback
netdev.
it is not stable via http 127.0.0.1 post.
since sometime ffserver says : there is not new data ready for read (the
result is from poll).
then no any data can be sent to remote vlc client for preview.
the video stream will be disconnected.
Does anyone have idea about http post to 127.0.0.1 from ffmpeg to ffserver?

why it is not stable?
