For some main-10 stream, sometime the luma is 8 bits while chrome is more
than 8 bits, which cause using the wrong NV12 surface as the render target
and decoding error.
Fix#176
When create vaapi surface, it is better to use the chroma type get
from jpeg file instead of using fixed 420 format. And the correct
chroma type can be determined by horizontal_factor/vertical_factor
flags that get from jpegparse.
The old mapping values return by gst_vaapi_utils_h265_get_profile_idc is
wrong, though GST_H265_PROFILE_IDC_MAIN and GST_H265_PROFILE_IDC_MAIN_10
happened to be the correct value.
We only support Annex A profile_idc (1-4).
When input frame's formate changes, vp{8,9} encoders don't reset their frame
counter, hence the newly created frame could become a P-frame, leading to some
major troubles (sigabrt in libdrm in case of vp9). This patch adds some frame
prediction-related reset logic to the `flush' methods of GstVaapiEncoderVP8 and
GstVaapiEncoderVP9 implementations.
There are many profile levels that can support
more than 102400 kbps. Thus, increase the max
allowed bitrate property value from 102400 kbps
to 2048000 kbps (same as msdk encoder plugins).
Adds vpp mirroring support to vaapipostproc. Use
property video-direction. Valid values are identity,
horiz or vert. Default is identity (no mirror).
Closes#89
v2: Use GstVideoOrientationMethod enum
v3: Don't warn for VA_MIRROR_NONE.
Use GST_TYPE_VIDEO_ORIENTATION_METHOD type.
v4: Query VAAPI caps when setting mirror value
instead of during per-frame processing.
v5: Return TRUE in warning cases when setting mirror value.
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.
fixes: #151
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.
Fixes#155
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.
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.
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.

This code is just confused. It's asking for at least as many bits of
(z-axis) depth as the root window has bits of (color) depth. For rgb565
or rgb888 this is harmless, but at 10 bits per channel this demands a
30-bit or deeper Z buffer. While some hardware could in principle do a
32-bit Z buffer, Mesa does not expose such fbconfigs (at least on Intel
and AMD).
We're not actually using the Z buffer, so just stop asking for one.
[wl_shell] is officially [deprecated], so provide support for the
XDG-shell protocol should be provided by all desktop-like compositors.
(In case they don't, we can of course fall back to wl_shell).
Note that the XML file is directly provided by the `wayland-protocols`
dependency and generates the protocol marshalling code.

native-id property is problematic since the variable that stores it is
gsize, which is platform specific, and in some is bigger than unsigned
long, and there are not way to handle gsize properties.
Also, GST_VAAPI_ID_INVALID is defined in gsize terms, and we would
like to keep using it for this scope.
This patch removes the native-id property and set it manually in
gst_vaapi_window_new_internal().
gst_vaapi_encoder_put_frame() and gst_vaapi_encoder_flush() duplicates
the same code segment where the coded buffer is created, the picture
encoded on it and pushed to the async queue.
The function gst_vaapi_encoder_encode_and_queue() refactor this.
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.
