Problem when using nv_omx_hdmi_videosink

When using the gstreamer plugin nv_omx_hdmi_videosink with input-selector, I find the ram usage raises every time the input-selector switches.
The elements linking is like:
fakesrc -> nvvidconv -> -----------
______________________________|
v4l2src -> nvvidconv -> input_selector -> nv_omx_hdmi_videosink

When monitoring the file “/proc/meminfo” , it is found that “NvMapMemUsed” increases as input-selector switchs. And every time “NvMapMemUsed” increases by the same amount of about 3.5MB.

I tried to replace nv_omx_hdmi_videosink with fakesink, the problem has never happened.

Anybody gives me a help?
Thanks!
