Description Guillaume Desmottes 2017-10-27 07:58:56 UTC 
gst-docs/examples/tutorial/basic-tutorial-8.c is raising a crash in audiovisualizer with master.

(It would be good to somehow integrate those examples in our CI system).

Thread 5 "video_queue:src" received signal SIGSEGV, Segmentation fault.

Comment 1 Tim-Philipp Müller 2017-11-04 10:57:24 UTC 
Works fine for me and is valgrind clean as well for me.

What videosink is this with in your case?

Does it happen pretty much immediately or only after a while?

Could you investigate?

> What videosink is this with in your case?

vaapisink (master).
If I remove it it switches to xvimagesink which is indeed working.
