vp8 v/s vp9 encoder in terms of performance

[Saurabh Bora]

Hi,
As suggested I added the property deadline=1 to the pipeline
gst-launch-1.0 videotestsrc ! autovideoconvert ! vp8enc deadline=1 ! vp8dec
! autovideosink

Still video streaming lags significantly when vp9 encoder is used.

Can you please help understand when must one use vp9 over vp8 and vice
versa?
Or is there a way to use vp9 encoder and achieve same performance as that
of vp8 encoder?
