Latency

Metric Mean Min Max StdDev
Demuxer Open 426µs 414µs 462µs 14µs
First Packet 533µs 487µs 625µs 41µs
First Frame 14.8ms 13.8ms 16.1ms 650µs
First Encoded Packet 25.9ms 24.1ms 27.4ms 838µs
Pipeline Total 26.0ms 24.6ms 27.6ms 923µs

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