GStreamer linux segfault on examples

Hello everyone,

I am going through the tutorials of GStreamer to start a project with it .

The first example from Basic tutorial 1: Hello world!

gives me a segfault on the code with the line “gst_bus_timed_pop_filtered”

No additional information comes along with it, even on a debug build. An strace shows

child_tid=0x7f7ae7fff910, parent_tid=0x7f7ae7fff910, exit_signal=0, stack=0x7f7ae77ff000, stack_size=0x7fff00, tls=0x7f7ae7fff640} => {parent_tid=[106083]}, 88) = 106083 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 futex(0x55efd9f09e60, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x55efda1bc188, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x55efda1b4198, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x55efda1b2c18, FUTEX_WAKE_PRIVATE, 1) = 0 futex(0x55efda1b2c48, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x55efda197ec0, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x55efda1b4168, FUTEX_WAKE_PRIVATE, 2147483647) = 0 futex(0x55efda1b4198, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x55efda1b2ca0, FUTEX_WAKE_PRIVATE, 2147483647) = 0 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x43} --- +++ killed by SIGSEGV +++

I have tried it on another physical computer, but it does the same segfault. Any ideas? The second example has similar issues. Is there a way to check my libraries, codes?

Both machines are on ubuntu

Edit1:

I mage a Ubuntu 22.04 Virtual Machine with the exact same code and cmake file. The example there works inside the VM but on the same (native) physical machine is does not work.

After some digging, I start my application like this:

GST_DEBUG=*:5 ./MainC

The environment variable gives additional debug printouts, here is the last few lines right before the crash.

I am working on the VM now and assume I have some library / dependency hell issue in the native OS which I cant clear out.

I moved this to a more appropriate category, as Nsight Compute is for the kernel profiling tool, only.

Hello @JohnMyer , Sorry for the late reply, Does the issue still exist?
As it is a pure GStreamer issue, we suggest you go to Gstreamer forum to get support, DeepStream forums focuses on DeepStream related topics, thanks.
