From: Wim Taymans Date: Mon, 20 Aug 2007 16:52:03 +0000 (+0000) Subject: gst/rtp/: Added an H263 depayloader. Fixes #369392. X-Git-Tag: RELEASE-0_10_7~320 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7d92376d3b9217c21731aa3c6d0966aded892e1f;p=platform%2Fupstream%2Fgst-plugins-good.git gst/rtp/: Added an H263 depayloader. Fixes #369392. Original commit message from CVS: * gst/rtp/Makefile.am: * gst/rtp/gstrtp.c: (plugin_init): * gst/rtp/gstrtph263depay.c: (gst_rtp_h263_depay_base_init), (gst_rtp_h263_depay_class_init), (gst_rtp_h263_depay_init), (gst_rtp_h263_depay_finalize), (gst_rtp_h263_depay_setcaps), (gst_rtp_h263_depay_process), (gst_rtp_h263_depay_set_property), (gst_rtp_h263_depay_get_property), (gst_rtp_h263_depay_change_state), (gst_rtp_h263_depay_plugin_init): * gst/rtp/gstrtph263depay.h: Added an H263 depayloader. Fixes #369392. * gst/rtp/gstrtph263pdepay.c: (gst_rtp_h263p_depay_setcaps), (gst_rtp_h263p_depay_process): * gst/rtp/gstrtph263ppay.c: (gst_fragmentation_mode_get_type), (gst_rtp_h263p_pay_class_init), (gst_rtp_h263p_pay_flush): Make the H263+ pay/depayloader support H263-1998 and H263-2000 payloads. Also alow plain H263 on the h263p payloaders.
