[streaming] H264 streaming using VLC

[Robert Howard]

Hi

I need some help with streaming H264 encoded video using VLC.

I have a hardware encoder using which I am encoding H.264 file. I am able to
play the file in latest version of VLC 0.8.6d, however I am unable to stream
the file. I am getting following trace while streaming,

=============================================

status change: ( stop state: 0 )

 =============================================

After parsing the entire file, the streamer just stops without streaming.
Any idea what H264 format VLC is looking for?

I am also attaching the H.264 encoded file.

MPEG4IP Tool output for the encoded file is as follows:
