Question 1

How do I install astiav with FFmpeg on Windows?

Accepted Answer

Follow the README's steps using msys2 and mingw64: install the toolchain, clone the repo, and set CGO_CFLAGS, CGO_LDFLAGS, and PKG_CONFIG_PATH to point to your FFmpeg build directory. This ensures proper linking for compilation.

Question 2

Is astiav stable enough for production use?

Accepted Answer

While it has full test coverage, the library explicitly warns about breaking changes without versioning, so you should regularly check the BREAKING_CHANGES.md file and plan for updates in your deployment pipeline.

Question 3

How does astiav compare to other Go FFmpeg bindings like goav?

Accepted Answer

astiav is a from-scratch rewrite aiming for a more idiomatic Go API with better error handling and examples, whereas goav might be older and less maintained. However, goav could offer broader FFmpeg version compatibility in some cases.

Question 4

Can I use astiav for real-time video streaming?

Accepted Answer

Yes, it supports hardware acceleration and filtering, but performance depends on your FFmpeg build and Go runtime; test with the provided examples and monitor resource usage, as the C bindings add some overhead.

Question 5

How to handle memory leaks in astiav?

Accepted Answer

Use the Alloc(), Unref(), and Free() methods as shown in the README patterns, which mirror FFmpeg's C memory management. Failing to call these properly can lead to leaks, so follow the examples closely.

Question 6

What's the learning curve like for astiav if I know FFmpeg C API?

Accepted Answer

It's relatively low because the library maps directly to C functions with Go idioms, but you still need to understand FFmpeg concepts; the detailed documentation with C links helps bridge the gap efficiently.
