These * filters vary depending on the installed and chosen * [VA-API](https://01.org/linuxmedia/vaapi) driver, but usually * resizing and color conversion are available. * * The generated surfaces can be mapped onto main memory as video * frames. * * Use gst-inspect-1.0 to introspect the available capabilities of the * driver's post-processor entry point. * * ## Example launch line * ``` * gst-launch-1.0 videotestsrc ! "video/x-raw,format=(string)NV12" ! vapostproc ! autovideosink * ``` * * Cropping is supported via buffers' crop meta. It's only done if the * postproccessor is not in passthrough mode or if downstream doesn't * support the crop meta API. * * ### Cropping example * ``` * gst-launch-1.0 videotestsrc ! "video/x-raw,format=(string)NV12" ! videocrop bottom=50 left=100 ! vapostproc ! autovideosink * ``` * * If the VA driver support color balance filter, with controls such * as hue, brightness, contrast, etc., those controls are exposed both * as element properties and through the #GstColorBalance interface. * * Since: 1.20 * */ /* ToDo: * * + HDR tone mapping */ #ifdef HAVE_CONFIG_H #include "config.h" #endif #include "gstvavpp.h" #include #include #include "gstvaallocator.h" #include "gstvabasetransform.h" #include "gstvacaps.h" #include "gstvadisplay_priv.h" #include "gstvafilter.h" #include "gstvapool.h" #include "gstvautils.h" GST_DEBUG_CATEGORY_STATIC (gst_va_vpp_debug); #define GST_CAT_DEFAULT gst_va_vpp_debug #define GST_VA_VPP(obj) ((GstVaVpp *) obj) #define GST_VA_VPP_GET_CLASS(obj) (G_TYPE_INSTANCE_GET_CLASS ((obj), G_TYPE_FROM_INSTANCE (obj), GstVaVppClass)) #define GST_VA_VPP_CLASS(klass) ((GstVaVppClass *) klass) #define SWAP(a, b) do { const __typeof__ (a) t = a; a = b; b = t; } while (0) typedef struct _GstVaVpp GstVaVpp; typedef struct _GstVaVppClass GstVaVppClass; struct _GstVaVppClass { /* GstVideoFilter overlaps functionality */ GstVaBaseTransformClass parent_class; }; struct _GstVaVpp { GstVaBaseTransform parent; gboolean rebuild_filters; guint op_flags; /* filters */ float denoise; float sharpen; float skintone; float brightness; float contrast; float hue; float saturation; gboolean auto_contrast; gboolean auto_brightness; gboolean auto_saturation; GstVideoOrientationMethod direction; GstVideoOrientationMethod prev_direction; GstVideoOrientationMethod tag_direction; gboolean add_borders; gint borders_h; gint borders_w; GList *channels; }; static GstElementClass *parent_class = NULL; struct CData { gchar *render_device_path; gchar *description; }; /* convertions that disable passthrough */ enum { VPP_CONVERT_SIZE = 1 << 0, VPP_CONVERT_FORMAT = 1 << 1, VPP_CONVERT_FILTERS = 1 << 2, VPP_CONVERT_DIRECTION = 1 << 3, VPP_CONVERT_FEATURE = 1 << 4, VPP_CONVERT_CROP = 1 << 5, VPP_CONVERT_DUMMY = 1 << 6, }; /* *INDENT-OFF* */ static const gchar *caps_str = GST_VIDEO_CAPS_MAKE_WITH_FEATURES (GST_CAPS_FEATURE_MEMORY_VA, "{ NV12, I420, YV12, YUY2, RGBA, BGRA, P010_10LE, ARGB, ABGR }") " ;" GST_VIDEO_CAPS_MAKE ("{ VUYA, GRAY8, NV12, NV21, YUY2, UYVY, YV12, " "I420, P010_10LE, RGBA, BGRA, ARGB, ABGR }"); /* *INDENT-ON* */ #define META_TAG_COLORSPACE meta_tag_colorspace_quark static GQuark meta_tag_colorspace_quark; #define META_TAG_SIZE meta_tag_size_quark static GQuark meta_tag_size_quark; #define META_TAG_ORIENTATION meta_tag_orientation_quark static GQuark meta_tag_orientation_quark; #define META_TAG_VIDEO meta_tag_video_quark static GQuark meta_tag_video_quark; static void gst_va_vpp_colorbalance_init (gpointer iface, gpointer data); static void gst_va_vpp_rebuild_filters (GstVaVpp * self); static void gst_va_vpp_dispose (GObject * object) { GstVaVpp *self = GST_VA_VPP (object); if (self->channels) g_list_free_full (g_steal_pointer (&self->channels), g_object_unref); G_OBJECT_CLASS (parent_class)->dispose (object); } static void gst_va_vpp_update_passthrough (GstVaVpp * self, gboolean reconf) { GstBaseTransform *trans = GST_BASE_TRANSFORM (self); gboolean old, new; old = gst_base_transform_is_passthrough (trans); GST_OBJECT_LOCK (self); new = (self->op_flags == 0); GST_OBJECT_UNLOCK (self); if (old != new) { GST_INFO_OBJECT (self, "%s passthrough", new ?
