GstVaapiPixmap is an abstract base class which only implementation
were GstVaapiPixmapX11. This class were used for a special type of
rendering in the tests apps, utterly unrelated in GStreamer.
Since gstreamer-vaapi is no longer a general-user wrapper for VA-API
we should remove this unused API.
This removal drops libxrender dependency.
That test case only works with drm display, so the build such as
meson -Dwith_x11=yes -Dwith_wayland=no -Dwith_drm=no -Dwith_egl=no
-Dwith_glx=no
gets a failure when run ninja test. Just enable this test when drm
is enabled.
The strides and offsets could be the same, but the allocation
size might be different (e.g. alignment). Thus, ensure we also
set the flag to copy from VA memory to system memory when alloc
size differs.
Fixes#243
If the dependent_slice_segment_flag is true, most slice info derived from last slice.
So we need check the slice type after we call populate_dependent_slice_hdr
Since commit 32bf6f1e GLTextureUpload is broken because i965
doesn't report properly RGBA support. It could be possible to use RGBx
but GLTextureUpload only regotiates RGBA.
The simplest fix to this regression is adding synthetically the RGBA
format in the internal format map.
Instead of break at the fist foud quirk in the table, iterate all over
so it would be feasible to add several quirks for one driver per
element in array.
The intel-media-driver (iHD) can't convert output color
primaries when doing YUV to/from RGB CSC. Thus, we must
keep the output color primaries the same as the input
color primaries for this case.

This reverts commit dd428cc4a1 because
it rewrites the buffer size whilst surface allocation flags are
stored when allocator_params_init() is called since fab890ce.
Fix: #239
When a vaapi allocator is instantiated, it first try to generate a
surface with the specified configuration.
This patch adds, in this tried buffer, the requested allocation flags.
Store surface allocation flags passed to the vaapi allocator in
GObject's qdata, because it might be used by the vaapivideobufferpool
when recreating the allocator given any resolution change.
When creating surfaces it is possible to pass to VA hints of its usage,
so the driver may do some optimizations.
This commit adds the handling of encoding/decoding hints.
In fact, gst_vaapi_create_test_display only test x11, wayland and
drm, no glx and egl entries. So if none of them is enabled, no
vaapi element can be detected.
The bug fixing, in commit 89f202ea, just considers the case when
surface's DMABuf is set through gst_buffer_pool_acquire_buffer(),
which is typically a decoder's behavior. But vaapipostproc doesn't
provide any surface when calling gst_buffer_pool_acquire_buffer(),
thus a surface is created when GstMemory is allocated.
If the surface proxy in buffer's meta is reset at
buffer_pool_reset_buffer(), that surface will be destroyed and it
won't be available anymore. But GstBuffers are cached in the buffer
pool and they are reused again, hence only those images are rendered
repeatedly.
Fixes: #232
I've just discovered iHD driver in Skylake doesn't have VideoProc
entry point, hence, in this platform, when vaapioverlay is tried to be
registered, critical warnings are raised because blend doesn't have a
display assigned.
As it is possible to have drivers without EntryPointVideoProc it is
required to handle it gracefully. This patch does that: only tries to
register vaapioverlay if the testing display has VPP and finalize()
vmethods, in filter and blend, bail out if display is NULL.
Commit 1168d6d5 showed up a regression: decode_sps() stores the unit's
parser info in sps array. If that parser info comes from decoding
codec data, that parser info will have an undefined state which might
break ensure_sps().
This patch sets the parser info state, at decoding codec data, with
the internal parser state. This is similar with h264 decoder apprach.

VAProcColorStandardExplicit and associated VAProcColorProperties
(primaries, transfer and matrix) are not supported until
VA-API 1.2.0.
Use VAProcColorStandardNone instead of VAProcColorStandardExplicit
if VA-API < 1.2.0.
Fixes#231
Addresses #228 on iHD side. It seems iHD can't handle
VAProcColorStandardSRGB in all situations for vpp. But
it has no problem when we specify the sRGB parameters
via VAProcColorStandardExplicit parameters.
We've always sent VA_SOURCE_RANGE_UNKNOWN to the driver.
And, the [iHD] driver essentially computes the same color
range as gstreamer when we send VA_SOURCE_RANGE_UNKNOWN for
cases were gstreamer computes it automatically. But,
if the user wants to make it explicit, we should try
to honor it.
The default output colorimetry is persuaded by the output
resolution, which is too naive when doing VPP cropping
and/or scaling. For example, scaling 4K(sink)->1080P(src)
resolution (i.e. both YUV) results in bt2020(sink)->bt709(src)
colorimetry selection and some drivers don't support that
mode in vpp.
Thus, if output (i.e. downstream) does not specify a
colorimetry then we use the input resolution instead of the
output resolution to create the default colorimetry. Also,
note that we still use the output format since it may be a
different color space than the input. As in the example
above, this will result in bt2020(sink)->bt2020(src)
colorimetry selection and all drivers (afaik) should support
that in vpp.
If colorimetry has been set by a capsfilter (e.g.
vaapipostproc ! video/x-raw,colorimetry=bt709) then
don't try to override it. Previously, the aforementioned
capsfilter will fail to negotiate if default colorimetry
is not the same as the capsfilter (e.g. 4K resolutions).
Some code can be optimized since only if the dmabuf allocator is set,
the internal flag of dmabuf is TRUE, thus there's no need to evaluate
the allocator address.
If the requested allocator in set_config() is not a VAAPI valid one,
reject the configuration, instead of lying and using a private one.
This patch superseeds !254 and !24
