Inputs / Sample code to build frame grabber on gstreamer-0.10

[Ashish Kumar Mishra]

Dear All , 

1) We are having an TI Dm816x core with Video and Audio input which is
stitched together to form 
    an avi / mkv  file . 

2) In one of our proposed plan , we need to support below mentioned
functionalities :-
    Rewind 
    Fast Forward / Backward 
    Slow Play
    Capture Frame 
    Forward Frame 
    Reverse Frame

Now could group members please provide an input based on their previous
exposure / any idea as to 
how could these be supported. 
The exposure i have is to create pipeline , pause ,start the pads and create
. 

3) Could team members let me know of any standard plugin we can use or to
achieve above mentioned functionality we have to build custom plugin ?

We are able to create an avi / mkv file by capturing audio & video and store
it to mSATA . 
Loosely this is our pipeline now ( created as proof of concept on Gstreamer
1.6 )
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 


Thanks,
