An FFmpeg runtime that can probe its version and run one encode from a pre-built argument array.
Two implementations exist: ProcessFfmpegRunner spawns a native binary
(desktop/CI) and WasmFfmpegRunner drives ffmpeg.wasm in a browser.
All argument planning happens upstream in FfmpegArgsBuilder, so both
runtimes execute the identical, fully-validated plan — a provider never
composes or rewrites arguments.

Methods
-
encode(
{required List< String> args, required Directory sandbox}) → Future<void> -
Runs one encode with exactly
args, resolving every relative file name againstsandbox(the per-render temp directory that confines all inputs and the output). -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
probeVersion(
) → Future< FfmpegVersion?> -
The runtime's FFmpeg version, or
nullfor an embedded runtime that has no honest banner to parse (ffmpeg.wasm ships a pinned build). -
toString(
) → String -
A string representation of this object.
