Frame Loss in mp4 stream

[Prabhakar Lad]

Hi,

I have the following pipeline:-
  gst_element_link_many (appvideosrc, videoqueue, vvalve, videoparse,
mux, filesink, NULL);
  gst_element_link_many (appaudiosrc, audioqueue, avalve, audioparse,
mux, NULL);


initially the vvalve and avalve elements 'drop' property is set to
TRUE, on after an event I set the 'drop' to FALSE and the data is
written to filesink.

I am observing that the there is a frame loss at this particular event
(when drop is set to false) in the video.

NOTE:- both appsrc are live

Any possible reasons why it looses the frames ? any possible solutions
to avoid this would be helpful.

Thanks,
