- Every subtitle and audio track the file carries, switched mid-playback.
- Picture in Picture, background listening and gestures that fit the medium.
FoxDL Almost every “cannot play this format” on an iPhone comes from the same place. The system player understands a short list of containers; anything else is handed back with a suggestion to convert it, and half an hour later you have a second copy of a film you already had.
A player carrying its own decoding stack has no such list. What changes in practice is not only which files open, but what survives inside them — the language tracks, the subtitles, the chapter marks that a conversion quietly throws away.

How do I play MKV files on iPhone, iPad or Mac?
Open the MKV in FoxDL and it plays. FoxDL decodes MKV itself instead of handing the file to the system player, so there is no conversion step and no waiting — and the subtitle and audio tracks inside the file stay selectable while it plays.
Read the guideWhich video and audio formats does FoxDL play?
FoxDL plays MKV, MP4, M4V, MOV, AVI, WebM, FLV and WMV video, MP3, M4A, AAC, FLAC, WAV, OGG, Opus and WMA audio, and HLS (m3u8) streams. Files play directly — there is no conversion step and no separate codec to install.
Read the guideHow do I turn on subtitles and choose between them?
Open the player menu while a video is playing and pick a subtitle track — every caption track inside the file is listed, along with an Off row. Subtitles are never switched on for you: a file with ten tracks opens silent until you choose one.
Read the guideCan I switch the audio track on a dual-audio file?
Yes. Every audio track inside the file is listed in the player menu and can be switched while the video is playing, without restarting it. Dual-audio MKVs — original language plus a dub — are the common case and are handled natively.
Read the guideDoes FoxDL support Picture in Picture and background playback?
Yes. Picture in Picture keeps video playing in a floating window while you use other apps, and audio keeps playing when the screen locks. Background audio is free for everyone; Picture in Picture is part of FoxDL Pro on every platform.
Read the guideDoes FoxDL have an equalizer?
Yes — a 10-band equalizer with presets, applied to whatever is playing: local files, podcasts, radio and IPTV audio alike. It is part of FoxDL Pro, and one subscription enables it on iPhone, iPad and Mac.
