Memory leak on usage of Line21 decoder
-
Tuesday, February 21, 2012 6:21 AM
Hi,
I am building a simple render application which reads the data from an
asf file and render it with VMR-9.It is being observed that the usage of Line21 decoder causes memory
leak of around 6MB.The line 21 decoder is just connected but it is not fed any cc data
since my source has no cc samples.After the graph build and cleanup I observe the process private bytes
gradually increase on each itteration.If I dont add the Line21 decoder I dont see the memory leak.Also have
checked the code with bounds checker tool which does not show any
leak.Here is the graph report:
