It is possible to interrupt playback while * being in this mode by pressing the Escape key. * * * This mode handles navigation events for every input device supported by * the DirectFB library, it will * look for available video modes in the fb.modes file and try to switch * the framebuffer video mode to the most suitable one. Depending on * hardware acceleration capabilities the element will handle scaling or not. * If no acceleration is available it will do clipping or centering of the * video frames respecting the original aspect ratio. * * * * * Embedded: this mode will render video frames in a * #GstDfbVideoSink:surface provided by the * application developer. This is a more advanced usage of the element and * it is required to integrate video playback in existing * DirectFB applications. * * * When using this mode the element just renders to the * #GstDfbVideoSink:surface provided by the * application, that means it won't handle navigation events and won't resize * the #GstDfbVideoSink:surface to fit video * frames geometry. Application has to implement the necessary code to grab * informations about the negotiated geometry and resize there * #GstDfbVideoSink:surface accordingly. * * * * For both modes the element implements a buffer pool allocation system to * optimize memory allocation time and handle reverse negotiation. Indeed if * you insert an element like videoscale in the pipeline the video sink will * negotiate with it to try get a scaled video for either the fullscreen layout * or the application provided external #GstDfbVideoSink:surface. * * * Example application * * * * * * Example pipelines * |[ * gst-launch -v videotestsrc ! dfbvideosink hue=20000 saturation=40000 brightness=25000 * ]| test the colorbalance interface implementation in dfbvideosink * */ #ifdef HAVE_CONFIG_H #include "config.h" #endif /* Our interfaces */ #include #include /* Object header */ #include "dfbvideosink.h" #include #include /* Debugging category */ GST_DEBUG_CATEGORY_STATIC (dfbvideosink_debug); #define GST_CAT_DEFAULT dfbvideosink_debug /* Default template */ static GstStaticPadTemplate gst_dfbvideosink_sink_template_factory = GST_STATIC_PAD_TEMPLATE ("sink", GST_PAD_SINK, GST_PAD_ALWAYS, GST_STATIC_CAPS ("video/x-raw-rgb, " "framerate = (fraction) [ 0, MAX ], " "width = (int) [ 1, MAX ], " "height = (int) [ 1, MAX ]; " "video/x-raw-yuv, " "framerate = (fraction) [ 0, MAX ], " "width = (int) [ 1, MAX ], " "height = (int) [ 1, MAX ]") ); /* Signals and args */ enum { ARG_0, ARG_SURFACE, ARG_CONTRAST, ARG_BRIGHTNESS, ARG_HUE, ARG_SATURATION, ARG_PIXEL_ASPECT_RATIO, ARG_VSYNC }; static void gst_dfbvideosink_bufferpool_clear (GstDfbVideoSink * dfbvideosink); static DFBSurfacePixelFormat gst_dfbvideosink_get_format_from_caps (GstCaps * caps); static void gst_dfbvideosink_update_colorbalance (GstDfbVideoSink * dfbvideosink); static void gst_dfbvideosink_surface_destroy (GstDfbVideoSink * dfbvideosink, GstDfbSurface * surface); static GstVideoSinkClass *parent_class = NULL; static GstBufferClass *surface_parent_class = NULL; #ifndef GST_DISABLE_GST_DEBUG static const char * gst_dfbvideosink_get_format_name (DFBSurfacePixelFormat format) { switch (format) { case DSPF_ARGB1555: return "ARGB1555"; case DSPF_RGB16: return "RGB16"; case DSPF_RGB24: return "RGB24"; case DSPF_RGB32: return "RGB32"; case DSPF_ARGB: return "ARGB"; case DSPF_A8: return "A8"; case DSPF_YUY2: return "YUY2"; case DSPF_RGB332: return "RGB33"; case DSPF_UYVY: return "UYVY"; case DSPF_I420: return "I420"; case DSPF_YV12: return "YV12"; case DSPF_LUT8: return "LUT8"; case DSPF_ALUT44: return "ALUT44"; case DSPF_AiRGB: return "AiRGB"; case DSPF_A1: return "A1"; case DSPF_NV12: return "NV12"; case DSPF_NV16: return "NV16"; case DSPF_ARGB2554: return "ARGB2554"; case DSPF_ARGB4444: return "ARGB4444"; case DSPF_NV21: return "NV21"; default: return "UNKNOWN"; } } #endif /* GST_DISABLE_GST_DEBUG */ /* Creates miniobject and our internal surface */ static GstDfbSurface * gst_dfbvideosink_surface_create (GstDfbVideoSink * dfbvideosink, GstCaps * caps, size_t size) { GstDfbSurface *surface = NULL; GstStructure *structure = NULL; DFBResult ret; DFBSurfaceDescription s_dsc; gpointer data; gint pitch; gboolean succeeded = FALSE; g_return_val_if_fail (GST_IS_DFBVIDEOSINK (dfbvideosink), NULL); surface = (GstDfbSurface *) gst_mini_object_new (GST_TYPE_DFBSURFACE); /* Keep a ref to our sink */ surface->dfbvideosink = gst_object_ref (dfbvideosink); /* Surface is not locked yet */ surface->locked = FALSE; structure = gst_caps_get_structure (caps, 0); if (!gst_structure_get_int (structure, "width", &surface->width) || !gst_structure_get_int (structure, "height", &surface->height)) { GST_WARNING_OBJECT (dfbvideosink, "failed getting geometry from caps %" GST_PTR_FORMAT, caps); goto fallback; } /* Pixel format from caps */ surface->pixel_format = gst_dfbvideosink_get_format_from_caps (caps); if (surface->pixel_format == DSPF_UNKNOWN) { goto fallback; } if (!dfbvideosink->dfb) { GST_DEBUG_OBJECT (dfbvideosink, "no DirectFB context to create a surface"); goto fallback; } /* Creating an internal surface which will be used as GstBuffer, we used the detected pixel format and video dimensions */ s_dsc.flags = DSDESC_PIXELFORMAT | DSDESC_WIDTH | DSDESC_HEIGHT /*| DSDESC_CAPS */ ; s_dsc.pixelformat = surface->pixel_format; s_dsc.width = surface->width; s_dsc.height = surface->height; /*s_dsc.caps = DSCAPS_VIDEOONLY; */ ret = dfbvideosink->dfb->CreateSurface (dfbvideosink->dfb, &s_dsc, &surface->surface); if (ret != DFB_OK) { GST_WARNING_OBJECT (dfbvideosink, "failed creating a DirectFB surface"); surface->surface = NULL; goto fallback; } /* Clearing surface */ surface->surface->Clear (surface->surface, 0x00, 0x00, 0x00, 0xFF); /* Locking the surface to acquire the memory pointer */ surface->surface->Lock (surface->surface, DSLF_WRITE, &data, &pitch); surface->locked = TRUE; GST_BUFFER_DATA (surface) = data; GST_BUFFER_SIZE (surface) = pitch * surface->height; /* Be carefull here.
