A resume control chooses a saved playback position when usable media remains available. It cannot manufacture a past programme section that the source does not provide.

Why HDR-to-SDR conversion is different from changing the container
Tone mapping changes how HDR image values are represented for SDR output. Simply repackaging compressed media does not perform that picture conversion.
Why an SDR capture can look different from the HDR television image
The display branch and capture branch can apply different processing. Identify the capture device and output mode before treating the recorded appearance as proof of the original signal’s look.
Why video orientation metadata can change presentation without rewriting every pixel
A track’s presentation transform and physically rotated image buffers are different mechanisms. Preserve that distinction when two applications show the same file differently.
Why an audio scheduling period is not the total sound delay
Dividing PipeWire quantum by rate gives a graph scheduling period. Other stages can contribute to the complete delay a listener experiences.
Why a system network graph is not a measurement of one programme
A desktop’s network activity can combine several applications and transfers. Keep the measurement scope separate from a single media stream’s bitrate.
