<div dir="ltr">Like I said, I can't even find out whether I have to link an audio pad to a fakesink or just drop it unlinked, whether I have to explicitly unlink pads (as long as I link them dynamically, on the "pad-added" signal, with a callback), or not. Each time I get source pads from decodebin with incremented ordinal numbers, which does not seem correct. This isn't explained in the manuals. Maybe I just don't unreference something correctly. What's the point in debugging something which doesn't probably comply to the developer's intentions?

Have you thought about installing all debug symbols (including
libvaapi and xorg video driver symbols) and running this through
valgrind ?<span class="HOEnZb"><font color="#888888"><br>
