1 year ago Hello, could you please add
-DCMAKE_BUILD_TYPE=DebugTo your CMake command so we could get line numbers in the gdb backtrace? additionally please use
bt -fullSo we can see variables with the added debug symbols, thank you.

(*): Shared library is missing debugging information.Hi,
We're currently investigating this issue. At this time we've found that the issue is unrelated to kvssink or gstreamer, and there is actually a build issue with alpine when constructing libcproducer.so . The samples in our producer-c reproduce the same issue. The segfault occurs because the memory address of the function is inaccessible memory.
We're still looking for solutions at this time.

1 year ago Hello,
We've resolved the issue in a PR that's undergoing review. The issue is due to the smaller default stack size of Alpine Linux. You'll need to call cmake -DCONSTRAINED_DEVICE=ON .. with the fix to get around this problem.

Logging

Describe the bug This is the same issue previously reported in #939. I'd like to use Alpine based images for our deployment, and while the build is successful, and
gst-inspect-1.0 kvssinkworks, at runtime the process fails with a segfault as detailed above in the logs. I also included any other relevant details I could dig up. It appears that the binaries forkvssinkare linked with the libcurl used in the SDK. I included my Dockerfile in the Open source Building section below.To Reproduce Steps to reproduce the behavior:
docker build . -t kvssink:latestsudo docker run -it --network="host" kvssink:latest /bin/shapk add gstreamer-toolsand optionallyapk add gdbgst-launch-1.0 -v videotestsrc ! x264enc ! kvssink stream-name=<stream> aws-region=<region> access-key=<key> secret-key=<key>Expected behavior The pipeline should run and sink test video to KVS (or indicate connection error if valid region/keys are not provided)
