We are talking about a program that definitely demonstrates leaks in vaapisink, and not about (any number of) your particular programs which do not.

Your program does not confirm that there are no leaks, whereas mine definitely PROVES there are leaks in vaapisink, fullstop. Explain to me what isn't still clear.

</span>The problem here is that it doesn't leak for others. For me using<br>
vaapisink after a videotestsrc or anything else really does not cause<br>
increased memory usage. So either you have to provide the information<br>
you're asked for or have to debug and fix it yourself.<br>
