Original commit message from CVS: 2005-07-01 Andy Wingo <wingo@pobox.com> * ext/theora/theoradec.c (theora_dec_src_getcaps): Implement a getcaps to do explicit caps. Needs to be done in all decoders, possibly via a base class. * configure.ac (GST_PLUGIN_LDFLAGS): Add videoscale. * ext/ogg/gstoggdemux.c (gst_ogg_pad_typefind): No need to set caps on the sink pad, just rely on the pad template. Also, setting ANY caps on a pad is not valid because the caps are not fixed. * sys/ximage/ximagesink.c (gst_ximagesink_buffer_alloc): Set the caps on the buffer, and get the width from the desired_caps if they're set. (gst_ximagesink_renegotiate_size): Implement via setting the desired_caps on the ximagesink. (gst_ximagesink_setcaps): Only reset the width of the player if it wasn't already set. Not sure if this is right. (gst_ximagesink_show_frame): Memcpy only for normal buffers. * sys/ximage/ximagesink.h (desired_caps): New field, is the caps that the user wants. NULL unless the window has been resized. * gst/volume/gstvolume.c (volume_transform): Adapt to basetransform refcount changes.
