And, if downstream requests a specific level, the caps are not
negotiated, because there is no mechanism right now to specify a
custom level in the internal encoder.
When the available caps doesn't intersect with the allowed caps in the
pipeline, a new caps is proposed rather than just expecting to
iterate.
Later, the intersected caps (profile_caps) is fixated in order to
extract the configuration.
The current get_profile just return one possible profile for the encode,
which is not enough. For example, if we want to support HEVC 4:4:4
profile, the input of encode should be VYUA rather than NV12 in HEVC
main profile. So the command line:
gst-launch-1.0 videotestsrc num-buffers=200 ! capsfilter \
caps=video/x-raw,format=VUYA,width=800,height=600 ! vaapih265enc \
tune=low-power init-qp=30 ! fakesink
can not work because vaapih265enc just report NV12 in sink caps, we need
to specify the profile obviously like:
gst-launch-1.0 videotestsrc num-buffers=200 ! capsfilter \
caps=video/x-raw,format=VUYA,width=800,height=600 ! vaapih265enc \
tune=low-power init-qp=30 ! capsfilter caps=video/x-h265, \
profile=main-444 ! fakesink
The encode should have the ability to choose the profile based on input
format automatically. If the input video format is VUYA, the main-444
profile should be auto choosed.
We modify to let get_allowed_profiles of each encode sub class to return
an array of all supported profiles based on downstream's allowed caps, or
return NULL if no valid profiles specified by downstream.
If no allowed profiles found, all profiles which belong to the current
encoder's codec will be the candidates.
The function gst_vaapi_encoder_get_surface_attributes collects the surface's
attributes for that profile list we just get.
So for this case, both NV12 and VUYA should be returned.
TODO: some codec like VP9, need to implement the get_profile() function.
The commit 67e33d3de2 ("vaapiencode: h264:
find best profile in those available") changed the code to pick a profile
that is actually supported by the hardware. Unfortunately it dropped the
downstream constraints. This can cause negotiation failures under certain
circumstances.
The fix is split in two cases:
1\ the available VA-API caps doesn't intersect with pipeline's allowed
caps:
* The best allowed profile (pipeline's caps) is set as the encoding
target profile (it will be adjusted later by the available profiles
and properties)
2\ the available VA-API caps does intersect with pipeline's allowed
caps:
* The intersected caps are fixed, and its profile is set as the
encoding target profile. In this case the is not the best profile,
but the minimal one (if VA-API reports the profiles in order).
Setting the minimal profile of the intersected caps is better for
compatibility.
This patch fixes other tests related with caps negotiation, for
example, it handles baseline profile, even when VA only supports
constrained-baseline.

Instead to look for the best profile in the allowed profiles by
downstream, the encoder should look for the base profile in the
available profile in VA-API.

Coverity scan bug:
An unsigned value can never be negative, so this test will always
evaluate the same way.
As len is guint32, there is no need to check it if it is equal or
bigger than zero.
So far vaapi encoder does not set profile to src caps. This patch makes it
setting profile to src caps, which is determined by itself.
In addition, if encoder chose different profile, which is not negotiated with
downstream, we should set compatible profile to make negotiation working.

Check if the requested profile in source caps, is supported by the
VA driver. If it is not, an info log message is send saying that
another (compatible?) profile will be used.

First check if downstream requests ANY caps. If so, byte-stream is
used and the profile will be choose by the encoder. If dowstream
requests EMPTY caps, the negotiation will fail.
Lately, byte-stream and profile are looked in the allowed caps.

The check for avc stream format was done in the vaapi encoder's
vmethod get_caps(), but that is wrong since it has to be check
when encoder set_format().

This new virtual method, get_profile(), if implemented by specific
encoders, will return the VA profile potentially determined by the
source caps.
Also it is implemented by h264 and h265 encoders, which are the main
users of this vmethod.

There is no difference in VAAPI surface caps between encoders and decoders.
Thus, the patch makes a simplification by removing encoders specific caps and
shares the same definition of VAAPI surfaces caps for all the elements.
Trying to comply with GStreamer's element names, this patch renames the
encoders using the name format vaapi{codec}enc.
In this way, the plugin documentation is linked correctly.

Refactor the main vaapi caps strings into three macros:
GST_VAAPI_MAKE_SURFACE_CAPS, GST_VAAPI_MAKE_ENC_SURFACE_CAPS and
GST_VAAPI_MAKE_GLTEXUPLOAD_CAPS.
Those are in gstvaapipluginutil.h so all the elements could use them, instead
of re-declaring them every time.
No functional changes.

The support for GStreamer 1.0 has been obsoleted in 0.5.10 release.
GStreamer 1.2 is the a minimal requirement for building the gstreamer-vaapi.
This patch removes all the pre-processor conditional code compilation guarded
for gstreamer-1.0.
Thus, all the video converters were removed too.

The purpose of gstcompat.h is to couple the API differences among
gstreamer-1.0 and gstreamer-0.10. Since gstreamer-0.10 is obsolete, the code
in this compatibility layer shall be removed.
Nevertheless, the gstcompat.h header should be kept, if new incompatibilites
appear in the future, but it shall live in gst/vaapi, not in gst-libs.
This patch removes the crumbs defined gstcompat.h and moves it to gst/vaapi.
In order to avoid layer violations, gstcompat.h includes sysdeps.h and all
the includes in gst/vaapi of sysdeps.h are replaced with gstcompat.h

Attach the codec_data to out_caps only if downstream needed.
For eg: h264 encoder doesn't need to stuff codec_data to the
src caps if the negotiated caps has a stream format of byte-stream.

Add initial support for Subset SPS, Prefix NAL and Slice Extension NAL
for non-base-view streams encoding, and the usual SPS, PPS and Slice
NALs for base-view encoding.
The H.264 Stereo High profile encoding mode will be turned on when the
"num-views" parameter is set to 2. The source (raw) YUV frames will be
considered as Left/Right view, alternatively.
Each of the two views has its own frames reordering pool and reference
frames list management system. Inter-view references are not supported
yet, so the views are encoded independently from each other.

Allow user to precise the largest profile to use for encoding due
to target decoder constraints. For instance, if CABAC entropy coding
mode is requested by "constrained-baseline" profile only is desired,
then an error is returned during codec configuration.
Also make sure that the suitable profile we derived actually matches
what the HW can cope with.

Various clean-ups to improve consistency and readability: rename some
variables, drop unused macro definitions, drop initialization of vars
that are zero-initialized from the base class, drop un-necessary casts.
The specified caps in gst_video_encoder_set_output_state() function
arguments should not contain any resolution, pixel-aspect-ratio,
framerate, codec-data et al. Those rather should be set through the
returned GstVideoCodecState. This means that output caps creation
could be delayed until before gst_video_encoder_finish_frame() is
called.
This greatly simplifies the GstVideoEncoder::set_format() callback
by the way.
Rename a few member functions to make them more consistent:
- alloc_encoder(): now reduced to allocate the encoder object only;
- alloc_buffer(): allocate buffer from srcpad, and copy bitstream.
