buffering issue with vlc 1.0.1

[Rahul Patel]

Hi,

I am playing h264 video in vlc-1.0.1 using RTSP streaming. It's playing video properly. But When I perform seek action means move slider in vlc, video got stopped after buffering 8% of data. Following is vlc log messages.

After this It continuously printing same message. I also observed one change in vlc-1.0.1 behaviour, in older version when I perform seek vlc was sending only play request with ntp time whereas in newer version it is first sending pause request than sends play request with ntp time. Is it issue with vlc buffering in 1.0.1?

Thanks in advance..
