The patch includes
1. Changes in encode element for populating the dmai buffer with the information
received from the decode element or the resize element. These elements were not
providing the pitch information which is required for any transcode
2. The pacth cleaned up further the previous patch in which we removed the Line
length duplicacy across the encode element.
3. Kept the copy of the sorce and destination buffer because of some bugs in the
accel copy wlgorithm This code has no impact and can be eleminated later.
4.gstti_videnc1_init_video fuction is being modified for inclusion of buffer
