From 1361d068742cde907d2932a1ab1589d1311dc086 Mon Sep 17 00:00:00 2001 From: Wim Taymans Date: Tue, 20 May 2008 09:29:28 +0000 Subject: gst/smpte/: Add new plugin that adds the SMPTE transition in the alpha channel of Original commit message from CVS: * gst/smpte/Makefile.am: * gst/smpte/gstsmpte.c: (gst_smpte_plugin_init): * gst/smpte/gstsmpte.h: * gst/smpte/gstsmptealpha.c: (gst_smpte_alpha_transition_type_get_type), (gst_smpte_alpha_get_type), (gst_smpte_alpha_base_init), (gst_smpte_alpha_class_init), (gst_smpte_alpha_update_mask), (gst_smpte_alpha_setcaps), (gst_smpte_alpha_get_unit_size), (gst_smpte_alpha_init), (gst_smpte_alpha_finalize), (gst_smpte_alpha_do_ayuv), (gst_smpte_alpha_do_i420), (gst_smpte_alpha_transform), (gst_smpte_alpha_set_property), (gst_smpte_alpha_get_property), (gst_smpte_alpha_plugin_init): * gst/smpte/gstsmptealpha.h: * gst/smpte/plugin.c: (plugin_init): Add new plugin that adds the SMPTE transition in the alpha channel of I420 and AYUV frames so that they can be blended with videomixer later on. Uses all niceties such as using base transform for efficient alloc and negotiation. It currently requires GstController to control the position in the transition effect. --- gst/smpte/plugin.c | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 gst/smpte/plugin.c (limited to 'gst/smpte/plugin.c') diff --git a/gst/smpte/plugin.c b/gst/smpte/plugin.c new file mode 100644 index 00000000..cacc80c4 --- /dev/null +++ b/gst/smpte/plugin.c @@ -0,0 +1,43 @@ +/* GStreamer + * Copyright (C) <2008> Wim Taymans + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Library General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
