*Note: FFmpeg CLI memory is measured via /usr/bin/time (macOS: -l, Linux: -v).

Latency

Metric Mean Min Max StdDev
Demuxer Open 466µs 430µs 561µs 41µs
First Packet 530µs 491µs 575µs 30µs
First Frame 11.7ms 7.2ms 15.2ms 2.7ms
First Encoded Packet 25.2ms 23.9ms 26.9ms 856µs
Pipeline Total 25.8ms 22.5ms 27.3ms 1.4ms

Note: Each metric is measured independently. "First Encoded Packet" uses default encoder settings while "Pipeline Total" uses tune=zerolatency for low-latency output.
