When the tune is NONE, we now can choose entrypoint freely. So the
GST_VAAPI_ENCODER_TUNE macro may not return the correct current
entrypoint.
We also delay CTU size calculation after entrypoint has been decided.
Some profile, such as H265_MAIN_444 on new Intel platform, may only
support ENTRYPOINT_SLICE_ENCODE_LP entrypoint. This leads two
problems:
1. We need to specify the tune mode like `vaapih265enc tune=low-power`
every time when we need to use this kind of profile. Or we can not
create the encoder context successfully.
2. More seriously, we set the entrypoint to a fixed value in
init_context_info() and so the create_test_context_config() can not
create the test context for these profile and can not get the
supported video formats, either.
We now change the entrypoint setting based on the tune option of the
encoder. If no tune property provided, we just choose the first
available entrypoint.
Instead of init_context_info() setting the passed profile, it is
assumed that it has to be set by each encoder.

GstVaapiMiniObject and GstVaapiObject are deprecated.
This is the first step to remove them by porting GstVaapiCodedBuffer
as a GstMiniBuffer descendant.

This patch makes use of GST_PARAM_USER_SHIFT to define the internal
param in encoders to decide which parameters to expose. Thus
gstreamer-vaapi will not interfere with any change in GStreamer in the
future.
Also, the internal symbol was change to
GST_VAAPI_PARAM_ENCODER_EXPOSURE to keep the namespacing.
G_PARAM_CONSTRUCT make all properties init correctly, we do not
need to init the properties manually.
G_PARAM_FLAG_VAAPI_ENCODER_EXPOSURE is a vaapi encoder specific
flag, means need to expose the property to according encode class.
Install properties for h265 encoder class. Also set the new get/set
property functions for gobject class. Still use the old properties
way now and this new feature will be enabled later.
Replace all gstvaapiobject in vaapi encoders with standard gstobject.
Let the gstobject common logic to handle all the init and finalize
works. But the property install/set/get still use the old way, need
to be improved later.
gst_vaapi_profile_get_name() returns a proper name for
GstCaps. Nonetheless, there are many profiles which don't have a name
representation for that realm.
gst_vaapi_profile_get_va_name() returns the name of the profile
according to its VAProfile name.
This new funtion is used in the encoder error message.
When enable low delay B, the reference list 1 will be same with
reference list 0, so need reset the num_ref_idx_l1_active_minus1
to num_ref_idx_l0_active_minus1.
Fixes: #160
g_assert will take no effect when glib's G_DISABLE_ASSERT macro is
defined. The function inside the g_assert will take no effect and
we will fail to set the correct slice number.
This patch fixes a regression from commit 5b1fe9c6.
max_qp, in rate control configuration, appeared in libva release
2.1 (API 1.1), thus it is required to guard the VA API version.
Fixes: #150
The current manner can not recognize the correct level and always
set the tier to main. Need to add frame rate check to recognize
levels such as 4.1, 6.2, etc. We also add a logic to check main
and high tier based on bitrate.
Fixes: #145
media-driver currently fails to set a correct value of max_qp when
min_qp is different to zero, in CBR and VBR mode, generating full
quality frames, thus unexpected huge output.
This patch sets max_qp to an arbitrary value to avoid this output
temporary.
Fixes: #144
Currently the minimal value for either min_qp and init_qp are 1,
but VA documentation specifiy that zero is also valid and means
to ignore the quantiser.
The default value is not changed though to avoid behaivor changes
to users.
In order to flush the pending pictures, a new internal encoder vmethod
is used: get_pending_reordered()
This method follows an iterator pattern which will return the next
picture to encode and push.
The base encoder will call this function in a loop when flush() is called.
For now, only H.264 and H.265 encoders implement this flushing mechanism.
Low delay B frame provide the function of transforming
P frame into low delay B frame which frame type is B, but
only reference predictive frames. This can be used when P
frame unsupported. Especially for P and B both unsupported,
in this case, I and low delay B frame can be encoded in a
stream.

The specification says,
"log2_max_pic_order_cnt_lsb_minus4 shall be in the range of 0 to 12, inclusive."
This patch changes the upper limit from 6 to 12.
https://bugzilla.gnome.org/show_bug.cgi?id=796179
pic_width_in_luma_samples/pic_height_in_luma_samples can be 16-bit rounded
instead of 32-bit.
In addition, codedbuf_size must be calculated according to this change.
https://bugzilla.gnome.org/show_bug.cgi?id=753229
Check input buffers for ROI metas and pass them to VA. Also added a
new "default-roi-delta-qp" property in order to tell the encoder what
delta QP should be applied to ROI by default.
Enabled it for H264 and H265 encoders.
https://bugzilla.gnome.org/show_bug.cgi?id=768248
Increased max values of periodic key frame for h26x codecs.
This allow more fine tunning of encoder that in certian scenario
want higher periodic key frame.
For example: it doesn't want a key frame each 10 seconds but
each 120 seconds.

Instead of handling the macroblock bitrate control as a integer, this
patch changes it as a enum, which is more self documented in the
GStreamer elements.
https://bugzilla.gnome.org/show_bug.cgi?id=787855
Creates 2 properties, qp-ip and qp-ib for setting different QP for P/B
frames
and set slice_qp_delta for each frame according to the value provided.
https://bugzilla.gnome.org/show_bug.cgi?id=785923
Creates new variable for QP for I frame and keep it at configuration and
use this for pic_init_qp and slice_qp_delta setting.
Since changing min qp doesn't make sense, keep min qp as is.

This is doing the same as h264 encoder as the following:
Using num_ref_frames provided and the result of the Query
VAConfigAttribEncMaxRefFrames, it determines the size of reference list
and perform encoding with multi reference frames as the following:
1\ The num_ref_frames is being considered as the number of
reference picture list0
2\ Encoder adds 1 reference frame more to the reference picture list1
internally if b-frame encoding.
3\ If num_ref_frames is bigger than the number of refrence frames
supported in the driver, it will be lowered.
Also this patch includes:
- Set num_negative_pics and num_positive_pics according to the number of
refs.
- Set delta_poc according to the number of refs.
- Increase max_dec_pic_buffering according to the number of refs
- Change max_num_reorder_pics according to num of bframes
https://bugzilla.gnome.org/show_bug.cgi?id=783804
Users can provide the number of reference frame by this property,
which is exaclty same as h264.
The value of the property will be considered as the number of
reference picture list0 and will add 1 reference frame more to the
reference picture list1 internally if b-frame encoding.
If the value provided is bigger than the number of refrence frames
supported in the driver, it will be lowered.
The maximum value is aligned to the value of the driver supported now.

Follows the specification as below:
7.4.7.1 in Rec. ITU-T H.265 v4 (12/2016)
num_ref_idx_active_override_flag equal to 1 specifies that the syntax
element num_ref_idx_l0_active_minus1 is present for P and B slices and
that the syntax element num_ref_idx_l1_active_minus1 is present for B
slices.
num_ref_idx_active_override_flag equal to 0 specifies that the syntax
elements num_ref_idx_l0_active_minus1 and num_ref_idx_l1_active_minus1
are not present.

Remove FIXME code, which makes previous assignation spurious.
This also means to make idr_period equal to keyframe period,
which is same as h264 encoder.
https://bugzilla.gnome.org/show_bug.cgi?id=783804
Coverity scan bug:
An assigned value that is never used may represent unnecessary
computation, an incorrect algorithm, or possibly the need for cleanup
or refactoring.
ip_period is assigned first to be rewritter inmediatly after. The
first assignation is spurious.
