H.264 encoded video has data distortion at the start of file.

[Ashish Kumar Mishra]

Hi All , 

I am working with v4l2src + alsasrc , the application creates multiple files
of user defined chunk 
The basic logic of the could be mapped to :- 
*gst-launch-1.0 -v v4l2src do-timestamp=true !
video/x-raw,width=960,height=720,framerate=30/1 ! timeoverlay
shaded-background=1 ! x264enc tune=zerolatency ! mux. alsasrc !
audio/x-raw,width=16,depth=16,rate=44100,channels=2 ! queue ! mux.
matroskamux name=mux  ! filesink *

The files has some quality issue at the start of every file created
,attached is the snapshot of the same. 
Basic google search pointed to some problems in H.264 frame . 

Could team member please provide some pointers as to how could this problem
be addressed. 
The video is proper after 3-4sec in every file. 

Thanks
