The APIs being invoked under this condition can't be moved to open.
msm_vidc_session_set_codec is called to set the codec which is not known at
open, and only known at s_fmt.
buffer sizes for different internal buffer will be known only after s_fmt.
hence these setting are being done in start streaming.
