Functions

func Initialize

func Initialize() (err error)

Initialize ensures that the ffmpeg WebAssembly module is decoded and pre-compiled in memory to a format that the WebAssembly runtime can instantiate.

If the module is already pre-compiled, this is a noop. This is called within Run(), but you can opt to call this yourself as the pre-compilation stage can be slow.

Note that this is safe to call concurrently.

func Run

func Run(ctx context.Context, args wasm.Args) (uint32, error)

Run will run ffmpeg with the given arguments, returning exit code or error. The first call to Run() may be slow if Initialize() has not already been called.
