Tim-Philipp Müller 6630236af4 video: add video overlay composition API for subtitles ... Basic API to attach overlay rectangles to buffers, or blend them directly onto raw video buffers. To be used primarily for things like subtitles or logo overlays, not meant to replace videomixer. Allows us to associate subtitle overlays with non-raw video surface buffers, so that subtitles are not lost and can instead be rendered later when those surfaces are displayed or converted, whilst re-using all the existing overlay plugins and not having to teach them about our special video surfaces. Could also have been made part of the surface buffer abstraction of course, but a secondary goal was to consolidate the blending code for raw video into libgstvideo, and this kind of API allows us to do both in a way that's minimally invasive to existing elements, and at the same time is fairly intuitive. More features and extensions like the ability to pass the source data or text/markup directly will be added later. https://bugzilla.gnome.org/show_bug.cgi?id=665080 API: gst_video_buffer_get_overlay_composition() API: gst_video_buffer_set_overlay_composition() API: gst_video_overlay_composition_new() API: gst_video_overlay_composition_add_rectangle() API: gst_video_overlay_composition_n_rectangles() API: gst_video_overlay_composition_get_rectangle() API: gst_video_overlay_composition_make_writable() API: gst_video_overlay_composition_copy() API: gst_video_overlay_composition_ref() API: gst_video_overlay_composition_unref() API: gst_video_overlay_composition_blend() API: gst_video_overlay_rectangle_new_argb() API: gst_video_overlay_rectangle_get_pixels_argb() API: gst_video_overlay_rectangle_get_pixels_unscaled_argb() API: gst_video_overlay_rectangle_get_render_rectangle() API: gst_video_overlay_rectangle_set_render_rectangle() API: gst_video_overlay_rectangle_copy() API: gst_video_overlay_rectangle_ref() API: gst_video_overlay_rectangle_unref()		2011-12-05 15:37:02 +00:00
