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.
Use VAPictureParameterBufferHEVCExtension&
VASliceParameterBufferHEVCExtension to pass extension setting from
some extension profile clips which may include these information.
The hevc extension setting only supported after libva release 2.2.0
(API 1.2.0).
Allow users to set the target-percentage for
variable rate controls. The default value is
70 (as hard-coded prior).
v2: minimum allowed value changed from 0 to 1
v3: target-percentage unchanged if CBR used
Resolves#129
The advanced trellis algorithm is supported in VA driver. We add
its support as a property named "trellis" of encoder.
It only works for H264 now, should be more in future.
Can not find a suitable chrome_type for this GST_VIDEO_FORMAT_RGB
packed 24 format. Just use GST_VAAPI_CHROMA_TYPE_RGB32 as its chrome
type. This kind of surface will just be created by new API with fourcc
and no old style chrome based creation is available.

Coverity scan bug:
If the function actually returns a null value, a null pointer
dereference will occur.
In gst_vaapi_encoder_ensure_param_roi_regions(): Return value of
function which returns null is dereferenced without checking
The decoder's surface chroma type should depend on the bit depth
of VP9's parser. For 10bits VP9 stream, we need to use P10LE kind
10 bits surface as the decoder result.

https://bugzilla.gnome.org/show_bug.cgi?id=748184 has resurrected
with commit 3e992d8a
Since gst_vaapi_find_preferred_caps_feature() returns a color format
from caps negotiation, different from the default one (NV12), the
postproc enables the color transformation. But when GL_TEXTURE_UPLOAD
feature is negotiated, no color transformation shall be done.
Nonetheless, with commit 3e992d8a the requested format changes
firstly, because there's no video sink yet, so ANY caps are
negotiated; but later, when there's a video sink and a caps
renegotiation, the GL_TEXTURE_UPLOAD is negotiated though the color
format conversion still ongoing. It is required to reset that
conversion.
This patch force default color format when GL_TEXTURE_UPLOAD is
selected as preferred, thus avoiding the color conversion.
Fixes: #157
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
string_of_va_chroma_format() gets a wrong string format description.
For example, the YUV420_10BPP get a string of 0x00000100 as output.
It's because VA_RT_FORMAT_xxx values are macro definitions. And
STRINGIFY(VA_RT_FORMAT_xxx) will expand to its real value
0x00000XXX.
To avoid the macro evaluation, it is changed to show only the color
format without VA_RT_FORMAT_ prefix.
When the downstream has any caps, then raw video feature will
be used. At this situation, the preferred format should be chose
from caps which contains "vide/x-raw" feature instead of from
the fist allowed caps.
Fixes#142
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.
x11_dep and libva_x11_dep are optional and meson ignores these
dependencies even if they are added into the dependency list.
This fixes the error below when libva-x11 is not avaiblabe:

GValueArray is deprecated. Use GstValueArray instead.
gst_param_spec_array can be deserialized from command line using:
vaapih264enc view-ids="<(uint)40,(uint)100>" num-views=2
While the g_param_spec_value_array() can not, and always get
error: "gst_value_deserialize_g_value_array: unimplemented"
Also fixed an out-of-range bug.
The order in gst_vaapi_enc_picture_encode when encoding one
picture is not very correct. The misc parameters are set before
the picture parameters. Some of the misc parameters such as
ROI may change the current picture parameters. But the later
setting of picture parameter will re-init all picture related
parameters and clear the previous setting. The right order
should be picture parameter first and then misc parameters.

The vaapi internal encoder's property id are negative, thus they are
different from GObject's property ids.
gst_vaapi_encoder_set_property() should map to the internal encoder
property id, assigned in gst_vaapiencode_default_set_property().
When downstream has any caps, vaapi should not shovel vaapi featured
buffers, but rather plain raw video, assuming always the worst case
scenario (downstream cannot handle featured video memory but raw
system memory buffers).
This patch query the peer caps without any filter, to know if
donwstream just ask for any caps, if so jump to the color space
checking, otherwise do the caps intersection and continue with the
feature selection algorithm.
Fixes: #139
We prefer to use the same format between image and surface for gst
vaapi allocator. The old way may choose different formats between
image and surface. For example, the RGBA image may have a NV12 surface.
So we need to do format conversion when we put/get image to surface.
Some drivers such as iHD can not support such conversion and always
cause a data flow error. There may also have some performance cost
for format conversion when put/get images.
So we prefer to use the same format for image and surface in the
allocator. If the surface can not support that format, we then
fallback to find a best one as the surface format.
