Browse source 
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.
