seg fault on 64 bit ARM
Locked

Hello,
I am trying to run a gst-launch pipeline on 64 bit ARM architecture. The only warning I see is from libde265dec. "dec.c:860:gst_libde265_dec_handle_frame:<libde265dec0>[00m warning: Cannot run decoder multi-threaded because stream does not support WPP (code=1000)" Can you tell what the problem is from the following debug output?

No, we can't tell what's wrong from that. You'll have to debug it. It's unlikely to be related to that warning debug message. Start by getting a stack trace of *all* threads, I don't think the thread you pasted there is the thread that crashes.

Hi Tim,
I issued the thread apply all bt command. I see that there are many threads and that the pthreads library is in use. Some of the threads seem to be waiting on a mutex. GDB suggests that some of the threads have a stack corruption. I am not sure what to look at next. Do you have any suggestions based on the output below?

No, we can't tell what's wrong from that. You'll have to debug it. It's unlikely to be related to that warning debug message. Start by getting a stack trace of *all* threads, I don't think the thread you pasted there is the thread that crashes.
