If the checkerboard * pattern is still visible after conversion, this indicates a faulty * conversion. Image manipulation, such as adjusting contrast or * brightness, can also cause the pattern to be visible. * * The Zone Plate pattern is based on BBC R&D Report 1978/23, and can * be used to test spatial frequency response of a system. This * pattern generator is controlled by the xoffset and yoffset parameters * and also by all the parameters starting with 'k'. The default * parameters produce a grey pattern. Try 'videotestsrc * pattern=zone-plate kx2=20 ky2=20 kt=1' to produce something * interesting. */ typedef enum { GST_VIDEO_TEST_SRC_SMPTE, GST_VIDEO_TEST_SRC_SNOW, GST_VIDEO_TEST_SRC_BLACK, GST_VIDEO_TEST_SRC_WHITE, GST_VIDEO_TEST_SRC_RED, GST_VIDEO_TEST_SRC_GREEN, GST_VIDEO_TEST_SRC_BLUE, GST_VIDEO_TEST_SRC_CHECKERS1, GST_VIDEO_TEST_SRC_CHECKERS2, GST_VIDEO_TEST_SRC_CHECKERS4, GST_VIDEO_TEST_SRC_CHECKERS8, GST_VIDEO_TEST_SRC_CIRCULAR, GST_VIDEO_TEST_SRC_BLINK, GST_VIDEO_TEST_SRC_SMPTE75, GST_VIDEO_TEST_SRC_ZONE_PLATE, GST_VIDEO_TEST_SRC_GAMUT, GST_VIDEO_TEST_SRC_CHROMA_ZONE_PLATE, GST_VIDEO_TEST_SRC_SOLID, GST_VIDEO_TEST_SRC_BALL, GST_VIDEO_TEST_SRC_SMPTE100, GST_VIDEO_TEST_SRC_BAR, GST_VIDEO_TEST_SRC_PINWHEEL, GST_VIDEO_TEST_SRC_SPOKES, GST_VIDEO_TEST_SRC_GRADIENT, GST_VIDEO_TEST_SRC_COLORS } GstVideoTestSrcPattern; typedef struct _GstVideoTestSrc GstVideoTestSrc; typedef struct _GstVideoTestSrcClass GstVideoTestSrcClass; /** * GstVideoTestSrc: * * Opaque data structure. */ struct _GstVideoTestSrc { GstPushSrc element; /*< private >*/ /* type of output */ GstVideoTestSrcPattern pattern_type; /* video state */ GstVideoInfo info; GstVideoChromaResample *subsample; gboolean bayer; gint x_invert; gint y_invert; /* private */ /* FIXME 2.0: Change type to GstClockTime */ gint64 timestamp_offset; /* base offset */ /* running time and frames for current caps */ GstClockTime running_time; /* total running time */ gint64 n_frames; /* total frames sent */ gboolean reverse; /* previous caps running time and frames */ GstClockTime accum_rtime; /* accumulated running_time */ gint64 accum_frames; /* accumulated frames */ /* zoneplate */ gint k0; gint kx; gint ky; gint kt; gint kxt; gint kyt; gint kxy; gint kx2; gint ky2; gint kt2; gint xoffset; gint yoffset; /* solid color */ guint foreground_color; guint background_color; /* moving color bars */ gint horizontal_offset; gint horizontal_speed; /* smpte & snow */ guint random_state; void (*make_image) (GstVideoTestSrc *v, GstVideoFrame *frame); /* temporary AYUV/ARGB scanline */ guint8 *tmpline_u8; guint8 *tmpline; guint8 *tmpline2; guint16 *tmpline_u16; guint n_lines; gint offset; gpointer *lines; }; struct _GstVideoTestSrcClass { GstPushSrcClass parent_class; }; GType gst_video_test_src_get_type (void); G_END_DECLS #endif /* __GST_VIDEO_TEST_SRC_H__ */
