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?
