FfmpegPool

axon::ots::subprocess::ffmpeg

Struct FfmpegPool 

Source 
pub struct FfmpegPool { /* private fields */ }
Expand description

TTL-bounded warm cache. The wrapper doesn’t keep the ffmpeg process alive across calls (we spawn per-call today) — the pool’s value is in caching the resolved pipeline descriptor

  • metrics, which is where the meaningful cost sits for small audio chunks. A follow-up revision can upgrade to a pipe-in / pipe-out long-running ffmpeg worker without changing this API.

Implementations§

Source§

impl FfmpegPool

Source

pub fn new(config: FfmpegPoolConfig) -> Self

Source

pub fn register(&self, pipeline: FfmpegPipeline)

Source

pub fn execute( &self, pipeline: &FfmpegPipeline, payload: &[u8], ) -> Result<Vec<u8>, OtsError>

Execute ffmpeg for this pipeline. Spawns per-call today; future revision upgrades to a long-running pipe-in worker.

Source

pub fn snapshot(&self) -> Vec<(String, u64, Duration)>
