Hi Malathi,
Thanks for the patch!

Any request for a change in bitrate after both planes
are streamed on is handled by setting the target bitrate
property to hardware.

Hmm, hfi_session_set_property already checks the instance state so
I
don't think those checks are needed. Another thing is that we need
to
take the instance mutex to check the instance state.
Yes Stan, "hfi_session_set_property" this property check the
instance
state,
but returns EINVAL if this is set at UNINIT instance state.
Controls initialization happens much earlier than session init and
instance init.
So the instance is still in UNINIT state which causes failure while
setting.
Through this patch we try to meet the client request of changing
bitrate
only
when both planes are streamed on.
Where does this requirement come from? It should be possible to set
the control at any time and it should apply to any encoding
happening
after the control is set.
With the patch, now video driver will set the control whenever client
sets
and will apply to encoder.
That's good, thanks for clarifying. I guess I misunderstood Malathi's
comment.
OK, just wonder about locking when we check streamon_out/cap flags?
Yes Stan, I agree that we should add an instance lock for these flags
check.
Posting the updated patch. Please review.
