The network-mount skip made SMB/NFS libraries fall back to live mpv text for
any release shipping subtitles only inside the container, losing karaoke
reconstruction, sidebar cues, and mining. The starvation it guarded against
had a different cause, and measured extraction runs at wire speed (~10s/GB
on gigabit) once per episode. Skip extraction only for true remote URLs,
which have no on-disk container to demux, and raise the extraction timeout
to cover large Bluray remuxes read over the network.
When embedded-track extraction is skipped (network-mounted media), live mpv
text during per-glyph typeset karaoke is a wall of simultaneous one-glyph
lines plus the syllable being typed. No parsed cues exist to substitute, so
the wall reached both overlays and recording verbatim. Detect bursts of many
single-glyph lines in the live fallback paths and drop them with their short
syllable companions, keeping concurrent dialogue lines.
