Non-Responsive Key Bindings for Visual + Numerical Filters (mpv QC View, #3 and #4)

[bturkus]

Summary

Key bindings 3 and 4 for the "Visual + Numerical" views in the mpv Lua script are currently unresponsive. When pressing these keys, no visualizations appear, despite other key bindings working as expected. Both views combine visual elements with associated numerical scores, intended to display broadcast and full-range views, respectively.

Details

Affected Key Bindings: 3 ("Visual + Numerical: Broadcast Range") and 4 ("Visual + Numerical: Full Range").

Expected Behavior: Display a composite of visual waveform and vectorscope views, with numerical range indicators for each.

Current Behavior: No response or visualization on pressing keys 3 and 4.

Related Issue

This issue is somewhat similar to an existing Audio Passthrough issue (#782), where audio passthrough functionality remains inactive due to a lavfi-complex requirement.

Thanks!
