can't seek/goto in vlc player

Postby Rahul Patel » 21 May 2009 16:58

I am using 0.9.9 vlc player as a client for playing RTSP/RTP streaming data.
VLC is playing video properly until I do seek/goto operation on it. Means when I move slider, vlc starts dropping the packets. :(
VLC messages window show following warning messages.

main warning: late picture skipped (97706880)
main warning: PTS is out of range (97587092), dropping buffer
main warning: late picture skipped (97713641)
main warning: PTS is out of range (97590585), dropping buffer
main warning: PTS is out of range (97588301), dropping buffer
main warning: PTS is out of range (97592571), dropping buffer
main warning: computed PTS is out of range (32426), clearing out
main warning: PTS is out of range (97591578), dropping buffer
main warning: output PTS is out of range (32454), clearing out
main warning: PTS is out of range (97585579), dropping buffer


And surprisingly this happens only in RTP over UDP when I do same thing in RTP over TCP or RTP over HTTP, everything works fine. :roll:
It seems vlc is not flushing it's buffer in case of RTP over UDP after seek operation.
I also observed that when I do backward seek/goto (move slider on back side), slider is coming back to it's previous position.

Is anybody facing same problem or having solution? :wink:
Is there any setting in vlc which can solve my problem?

Note: My RTSP server has support for npt range and RTP-Info. So it can handle seek request.
