vp8enc : Failed to initialize encoder

[Saurabh Sabnis]

Yes, it was problem with the framerate. I added "videorate ! video/x-raw,
framerate=30/1" after the vp8dec in the pipeline and it worked.
Just FYI, without the framerate cap, it was giving the same error on 1.0 as
well.

Thanks a lot for helping.
