What it does

What Dr.Player does.

Everything listed here ships today. Nothing is planned or in progress.

Play

Opens .mp4, .m4v, .mov and .webm from Explorer’s Open with menu
Play, pause, seek and volume
Becomes the default only when you pick it in Windows’ own UI

Waveform seek bar

Thin live bar from the first frame, waves fill in left to right
Finished decodes are cached on disk, so reopening is instant
Undecodable audio keeps the working thin bar, no error

Frame stepping

Steps at the file’s own rate, 24 to 120 fps
Falls back to 1/60 s where the engine stays silent
A measured step, not a frame-accurate seek

Resume

Continue from HH:MM:SS chip, up for ten seconds
Written on pause and on close, cleared at the end
Never written while loop is on
