Marco Paniconi [Fri, 18 May 2018 22:09:55 +0000 (15:09 -0700)]
vp9-svc: Fix on disabling inter_layer prediction.

In vp9_svc_constrain_inter_layer_pred() we disable the
inter_layer prediction if anything but only the previous
spatial layer (from same supeframe) is used for inter_layer
prediction. This check and disabling was only allowed when
the control VP9E_SET_SVC_INTER_LAYER_PRED is set to
INTER_LAYER_PRED_ON_CONSTRAINED.

But the control VP9E_SET_SVC_INTER_LAYER_PRED is needed for setting:
INTER_LAYER_PRED_ON/INTER_LAYER_PRED_OFF/INTER_LAYER_PRED_OFF_NONKEY.
So there is a conflict with setting INTER_LAYER_PRED_ON_CONSTRAINED.

Fix for now is to always allow for this disabling check
(disable inter_layer reference if its not previous spatial layer) as
long as inter_layer prediction is used (i.e., not set to _OFF).

A separate fix if needed may be to invoke another control for setting
INTER_LAYER_PRED_ON_CONSTRAINED.

This was causing an issue with enabling spatial layers on the fly
(say spatial layer 2), where since INTER_LAYER_PRED_ON_CONSTRAINED was
not set (default), the inter_layer prediction was then using a reference
from 2 spatial layers below (spatial layer 0).

vp9-svc: Fix issue with reseting lst_fb_idx.

When encoding a given spatial layer and the same spatial layer
on previous superframe was dropped (or disabled due to 0 bitrate),
the lst_fb_idx for current layer is set to the buffer index that
was last updated on TL0 frame (for the same spatial layer).

This condition was to maintain proper temporal prediction pattern
under frame drops, and it should only apply to INTER frames.

But the condition was causing an assert to be triggered on spatial
layers whose base are key frames. Fix is to condition this reset of
lst_fb_idx on the "is_key_frame" flag. Also initialize the
fb_idx_upd_tl0 to -1 and only use it for a given spatial layer
if its been set.

These issues can happen when superframe drop happens just before
a key frame, or when stream starts with lower layers and dynamically
enabled higher spatial layers.

Added datarate unittest the inserts key frame after superframe drop,
and verified that this fix is needed for test to pass.
Also modified the existing DisableEnable spatial layer test to trigger
the issue of using fb_idx_upd_tl0 when it hasn't been set for a
spatial layer.

Improved slide show coding

This patch improves coding of slide shows with fade or other
complex transitions.

Previously, fades and other complex transitions between static "slides"
were sometimes being incorrectly marked such that they were coded
as a single static slide rather than two slides with a transition.

As the initial key frame for the first slide is not necessarily a good
predictor of the second slide and ARFs were turned off, this led to a
poor visual and metrics outcome in some such cases.

This patch allows for long GF groups in static sections before and after
a complex transition (instead of just with  simple slide transitions) with
one or more normal ARF groups during the transition. It also enforces a
single "normal" length GF group after the transition before any extended
group is allowed. The reason for this is that the ARF that spans the
transition my not have a very high quality and hence may not act as a
good GF for the long static section that follows.
