libswscale: Memory leak in gst_video_frame_map. 

gst-libav-1.12.1/gst-libav-1.12.1/ext/libswscale

In function "gst_ffmpegscale_transform" at line: 587
gst_video_frame_map at line 596:

if  "gst_video_frame_map" failed then there is no unmap of in_frame.So I think
it will cause memory leak.


Solution:  if gst_video_frame_map is failed then there should 
gst_video_frame_unmap (&in_frame);

Please consider it.
