Hi

I have a question about the release of all memory

Let sample_decode execution in loop

Memory is slowly increasing

Not all free memory

Why memory is slowly increasing?

Hello,

This means that there are memory leaks in the sample app. Could you please tell the version you are using?

Thanks,

Could you please try with Media SDK 3.0 Beta version? If you still see the memory leak please provide the command line you use to run sample-decode. Are you using software Media SDK library or a hardware one?

Thanks,
Nina

Ourinvestigationhas not finished, but here is a status update. There is a deeper issue here which we have been able to reproduceoutside oftheMedia SDK and samples. The good news is that, even with multiple simultaneous sessions, the memory use increaseis slow -- and becomes slower with more iterations.

Thank you for your help with pointing out this issue.
