Okay. will split accordingly.

Actually we are sorting as per node name. Hence kept it here. As per
previous reviewer comments, sorted accordingly.

Please suggest better approach.

Okay. will change accordingly.

Actually we are sorting as per node(codec) name. Hence kept it here. As
per previous reviewer comments, sorted accordingly.

Please suggest better approach.
