2021-09-23test: gstreamer: Simplify single stream test using functions from GstUtilsVedant Paranjape
Simplify memory handling and complexity of the test by using gst_parse_bin_from_description_full [1].

2021-09-23test: gstreamer_single_stream_test: Fix memory leakVedant Paranjape
The test hold a valid reference to convert0_ and sink0_ but not released. This results in a memory leak and can be checked via valgrind. Drop the references with test cleanup() virtual function.

2021-09-08test: gstreamer: Factor out code into a base classVedant Paranjape
A lot of code used in the single stream test is boiler plate and common across every gstreamer test. Factor out this code into a base class called GstreamerTest. Also update the gstreamer_single_stream_test to use the GstreamerTest base class.

2021-08-26test: gstreamer: Disable gstreamer registry forksVedant Paranjape
ASan needs to be loaded first before gstreamer is loaded. This was not possible, so verify_asan_link_order was disabled. Better way to tackle this issue was disabling forks on the gstreamer side. verify_asan_link_order=0 disables the check on ASan side which checks if ASan was loaded before any other shared objects. Since, gstreamer spawns a child helper process while building the registry, we needed to disable this check. But with gst_registry_fork_set_enabled() it is possible to disable spawning this child helper process, so this ensures that ASan is loaded before any other shared object is loaded.

2021-08-26test: gstreamer: Clean up memory managementVedant Paranjape
This patch simplifies memory management, i.e., by replacing bare pointers with g_autoptr or g_autofree according to use case. While at it also update time representation of timeout variable with GST_SECOND.

2021-08-14test: gstreamer: Add test for gstreamer single streamVedant Paranjape
This patch adds a test to test if single stream using libcamera's gstreamer element works. We need to work around two distinct issues with ASan when enabled in the build: - glib has a known leak at initialization time. This is covered by the suppression file shipped with glib, but it's not clear how to use it automatically. For now, disable leak detection to avoid test failures. - GStreamer spawns a child process to scan plugins. If GStreamer is compiled without ASan (which is likely) but libcamera is, dlopen()ing the libcamera plugin will cause an ASan link order verification failure. Disable the verification child processes to work around the problem. This requires gcc 8 or newer.
