2022-12-24test: v4l2_compat: Reduce indentationLaurent Pinchart
Return early with subdir_done() to reduce indentation in case the v4l2_compat layer is not enabled. This matches our usual code patterns in meson.build files, and prepares for enabling the v4l2_compat test with ASan.

2022-01-17test: v4l2_compat: Add --verbose argumentLaurent Pinchart
Add a -v/--verbose argument to the v4l2_compat test to print the output of v4l2-compliance, even when the test passes. This can be useful when debugging.

2021-09-23test: v4l2_compat: Skip vimc as a test candidatePaul Elder
As the vimc scaler prevents us from passing v4l2-compliance, skip it until the fix has been merged. Instead of removing it from the supported_pipelines list, add an extra check, since we will have the same construct later when we check for the kernel version.

2021-09-19test: v4l2_compat: Report test as skipped if no compatible driver foundLaurent Pinchart
The V4L2 compatibility layer test includes a list of supported devices, as V4L2 compatibility isn't officially supported with all devices yet. If no supported device is present, the test reports success, while it actually hasn't run. Report it being skipped in that case.

2021-09-10test: v4l2_compat_test: Fix v4l2-compliance version parsingPaul Elder
v4l2-compliance changed their version string: v4l2-compliance 1.21.0-4618 v4l2-compliance SHA: cc211b76476aca2c072ffa83a9b003957d5f3909, 64 bits, 64-bit time_t v4l2-compliance 1.21.0-4838, 64 bits, 64-bit time_t The current parsing takes the last result of split, which works for the former, but not the latter. Take the second result of split instead, and strip away any commas.

2021-09-01test: v4l2_compat: Disable test when ASan is enabledLaurent Pinchart
The V4L2 compat test runs v4l2-ctl and v4l2-compliance with v4l2-compat.so preloaded. If libcamera is compiled with the address sanitizer enabled, the ASan library will be loaded due to preloading v4l2-compat.so. This however doesn't occur early enough in the dynamic linking process due to the v4l2 executables not being themselves linked to the ASan runtime, which causes ASan to abort with ==2198==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. Using LD_PRELOAD to load the ASan runtime would fix this issue, but it requires knowing the absolute path to the ASan shared object. This is compiler-dependent and for clang, architecture-dependent as well. Until we figure out how to safely retrieve that information, disable the test when ASan is enabled as a quick fix.

2020-07-17tests: v4l2_compat: Fix v4l2-compliance and v4l2-ctl version parsingPaul Elder
v4l2-compliance originally printed the SHA before the version, leading to the indexing that was used previously. Now that the version is printed before the SHA, the indexing is incorrect. Fix this. Although v4l2-ctl doesn't suffer the same issue, it is more correct to use the zeroth index like the v4l2-compliance version check now does, so fix that as well.

2020-07-13tests: v4l2_compat: Prettify failure outputPaul Elder
When a test is being run on a video device, there is output like so: Testing /dev/video0 with uvcvideo driver... and when it succeeds, "success" is appended: Testing /dev/video0 with uvcvideo driver... success On failure, however, the output of v4l2-compliance is printed before "failure" is printed, resulting in the first line of the v4l2-compliance output to be printed on the same line as the message: Testing /dev/video2 with uvcvideo driver... v4l2-compliance SHA: not available, 64 bits <v4l2-compliance output> failure Refactor the code to make "failure" print before the output of the test, to prettify the output upon failure.
