FAQPage Schema
How do I debug an OBS Studio plugin crash?

To debug an OBS Studio plugin crash, set up a debug build, attach a debugger like GDB or LLDB, and analyze memory issues using tools like AddressSanitizer or Valgrind.

Can I write unit tests for OBS plugins written in Rust?

Yes, you can write unit tests for OBS plugins written in Rust using `cargo test`, while C/C++ plugins can be tested using custom harnesses to verify individual components.

What is the best way to log variables inside an OBS Studio plugin?

The best way to log variables inside an OBS Studio plugin is using the built-in `blog()` function, which captures runtime information for debugging and integrated testing.

Does AddressSanitizer work with C++ OBS Studio plugins?

Yes, AddressSanitizer works with C++ OBS Studio plugins to detect memory errors, and you can complement it with Valgrind for deeper memory checks during testing.

How do I set up a test environment for OBS plugin development?

You set up a test environment for OBS plugin development by configuring a debug build, integrating testing frameworks like `cargo test` or custom harnesses, and utilizing OBS's `blog()` logging for integrated testing.

Why use Valgrind when debugging OBS plugins?

Use Valgrind when debugging OBS plugins to perform comprehensive memory checks and detect leaks or invalid memory access that might not surface during standard unit testing.
