Original commit message from CVS: * gst/flx/flx_color.h: * gst/flx/flx_fmt.h: * gst/flx/gstflxdec.c: (gst_flxdec_init), (gst_flxdec_src_query_handler), (flx_decode_color), (gst_flxdec_chain): * gst/flx/gstflxdec.h: Set MALLOCDATA for the temp buffers so we don't leak. Some debug cleanups. Consume all data in the adapter before leaving the chain function. Fixes #330678.
