In commit 18031dc6 surface's parent context is not assigned because of
circular references. Since then (2013), there's has no issue with
subpictures attached to a context, the current only users of this API.
This patch cleans up all of related code with the unused surface's
parent context.
This code doesn't define the profile used by the internal encoder, but
it used to "predict" which is going to be used and to get the caps
restrictions.
Before the profile was predicted by checking the donwstream caps, but
sometimes they are not defined, setting an unknown profile. In order
to enhances this situation, the encoder asks to internal encoder if it
has one. If so, it is used.
To ask the internal encoder's profile a new accessor function was
added: gst_vaapi_encoder_get_profile()
Now that vaapipostproc can possible handle video-direction, it
should also handle the image-orientation event from upstream if
video-direction property is set to auto.
It is requiered to know if postproc is capable to change the video
direction before fixating the source caps.
In order to do it, it'ss required to know if there's a functional VPP,
but that's checked at create() vmethod, which occurs after caps
fixating.
This patch checks for a functional VPP at fixate caps and, if so,
checks for the enabled filtes and later do the caps fixations.
If the video direction is unsupported by the driver, an element
warning is posted in the bus to notify the application.
gst_vaapi_enum_type_get_nick() was added in the library thus it can
be used elsewhere. It retrives the nick from an enum gtype.
The main reason to demote the message's level is because it is not an
error, it's a possible output of the trial and there's a code path
that handles it.
Secondly, it's very annoying when using gallium driver for radeon.
Otherwise the queue will swallow all the available decoder's surfaces
reaching a dead-lock.
This setting might impact the bin's peformance, but it's a trade-off.
When the code path goes to push buffers downstream when no surface
available in decoder context, and it fails the code bails out with a
fatal error.
That behavior is wrong, since it shouldn't be fatal. The use case is
when the video stream is disabled.
This patch just ignores the errors in this situation and demotes the
level of a log message.
For surfaces with different chroma type, it is prefer to initialize
a format which chroma type should be same with surface chroma type
instead of using fixed NV12.
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.
If the allocation caps and negotiated caps are the same,
then ensure any previously negotiated video info is also
removed. This can occur when multi-resolution video
decoding returns to it's original resolution.
Fixes#170
This fixes a deadlock in gst_vaapiencode_change_state, which was due to
srcpad's chain function was locked waiting for available buffers. Since the
coded buffers in codedbuf_queue become available after sinkpad consume the
encoded frames, Paused -> Ready state change leads to deadlock. Coded buffers
are never consumed and marked free, hence gst_vaapiencode_handle_frame waits for
available buffers and holds the stream_lock of the srcpad.
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.
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
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 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.

[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.

Fix the deinterlace black frame when playing with glimagesink:
gst-launch-1.0 filesrc location=test.264 ! h264parse ! vaapih264dec \
! vaapipostproc deinterlace-mode=1 deinterlace-method=1 ! glimagesink
The gst_vaapi_plugin_base_get_allowed_raw_caps is used for both sink
pad and src pad, which cause some bugs. For sink pad, we need to verify
vaPutImage() while for the src pad we need to verify vaGetImage().
For vaapidecoderXXX kind of plugins, the case is more complex. We need
to verify whether the decoded result(in some surface, NV12 format most
of the time) can be vaGetImage to some raw image format. Add more check
to fix all these problems.

Add 444 10bit yuv format Y410, which can be used to decode
main-444 10bit streams. Currently, this feature is only
supported by media-driver in Icelake.
The extract_allowed_surface_formats function just check whether
we can support some kind of surface/image format pair. We just
need to create a surface, create an image with the same video-format
and putImage from image to surface. All these operations success,
that kind of video-format is supported.
The old manner do not work for some kind of video-format. For example,
the RGBA kind of format will create a NV12 surface and RGBA image,
and the putImage will fail because the format is not same. And so
the RGBA format is not supported but actually it is supported.
gst_vaapi_plugin_base_close() removed the raw caps that are used indirectly
in gst_vaapipostproc_transform_caps(). The usage is already protected by
the mutex.
This is needed when the pipeline is stopped during startup.
gl_platform_type in gst_vaapi_get_display_type_from_gl_env generate
unused-variable warning and may block build when Werror enabled.
Several functions like gst_vaapi_display_egl_new_with_native_display
have no prototype warning and link error when GL is enabled but EGL
is disabled. Fix all these warning and link error.
