Using gstreamer buffer instead of v4l2src

Mazahir Poonawalla
Hi,

I use the following plugin to capture data from camera:

"gst-launch  v4l2src chain-ipipe=true always-copy=false input-src=composite ! 'video/x-raw-yuv,format=(fourcc)NV12, width=736, height=480, framerate=(fraction)30000/1001' ................................"

I would like to know whether I can replace "v4l2src chain-ipipe=true always-copy=false input-src=composite"  by some buffer. I mean can I pass a buffer with similar data to the rest of the pipeline in gst-launch? If yes, how can I do it. I do not want to use filesrc. It has to be a buffer containing the frame data (i.e. some kind of array).

Please let me know.

Thanks,
Maz
