capture video h264, miss header

Hi all,

I use this pipeline on dm365 to capture h264 video from rtsp-server:

  gst-launch \
     rtspsrc latency=50 rtsp:// ! \
     rtph264depay \
     rtph264pay \
     valve drop=TRUE \
     filesink location=/var/tmp/record.264

When I send ad interrupt valve drop parameter change rom TRUE to FALSE,
and after Xsecs, re-change from FLASE to TRUE. So I obtain a h264 video of Xsecs.

The problem is that I can't play the video.
For me, probably, this is due to the missing of heander h264 beacuse I didn't captured video
from the beginning of the stream. Mainly, I capture video from time X to time Y.

Any suggestions about this isseu?

Tnx in advance,
