Question 1

What file formats does Media Player support?

Accepted Answer

Whatever your browser supports natively — typically MP4, WebM, MOV (H.264), MKV (limited), MP3, WAV, OGG, M4A, FLAC — plus MIDI (.mid) and Yamaha SMAF ringtones (.mmf), which are synthesized in the browser. Drag-and-drop a file or pick from disk.

Question 2

Are my files uploaded?

Accepted Answer

No. Files stay on your device. Regular audio/video uses object URLs; MIDI and MMF are decoded locally and played through the Web Audio API. Nothing is uploaded; no server is involved.

Question 3

Can it play MIDI or old phone MMF ringtones?

Accepted Answer

Yes. Drop a .mid / .midi file and it plays through a General MIDI synth in the browser. Yamaha SMAF .mmf ringtones are converted locally from their score track and played the same way. Use the timeline slider or skip buttons to seek. Playback speed is not available for MIDI/MMF.

Question 4

Can I cast to my TV?

Accepted Answer

AirPlay (Safari) and Chromecast (Chrome on Android) icons appear automatically in the standard browser video controls. Local files cast successfully on most modern TVs.

Question 5

Does it remember my play position?

Accepted Answer

Per-file resume position is stored in localStorage keyed by file name and size, so reopening the same file picks up where you left off.
